Post-traumatic epilepsy: its complications and impact on occupational rehabilitation--an epidemiological study from India. (1/4600)

The objective of this study was to assess the prevalence of seizure disorder, neuropsychiatric disorders and reproductive outcome of employees with post-traumatic epilepsy (PTE) and their effect on occupational rehabilitation. A case-comparison group study design was used to compare 30 subjects with PTE with (1) 129 non-PTE and (2) 55 non-PTE matched control employees. The 55 non-PTE matched controls were selected from the 129 non-PTE employees on the basis of age, age at onset of seizure, age at marriage and length of employment. The PTE group had a lower fertility rate than the controls and more neuropsychiatric disorders and seizure disability. PTE employees were more occupationally rehabilitated than non-PTE employees (p = 0.033). Of the 30 PTE subjects, thirteen who were rehabilitated by placement had more seizure disability (p = 0.007) and a higher fertility rate (p = 0.018). High prevalence of seizure disability and increased fertility rate among the placed PTE employees suggested that there might be some association between severity of seizures and increased production of live offspring and work placement. Work suitability or placement should not be judged on clinical assessment only but psychosocial seizure assessment, disability evaluation and other psychometric tests which are of equal importance.  (+info)

Molecular control of the implantation window. (2/4600)

Human endometrium is the end organ of the hypothalamic-pituitary-ovarian axis. Therefore, endometrium is susceptible to changes in the cases of infertility that originate from disturbances in the normal functioning of this axis. In addition, some cases of unexplained infertility may be due to altered endometrial function. This disturbed endometrial function may originate from lesions in the molecular repertoire that are crucial to implantation. Human endometrium becomes receptive to implantation by the blastocyst within a defined period during the menstrual cycle. The duration of this so-called 'endometrial receptivity' or 'implantation' period seems to span from few days after ovulation to several days prior to menstruation. Successful implantation results from a co-ordinated series of events that would allow establishment of a timely dialogue between a receptive endometrium and an intrusive blastocyst. The members of the molecular repertoire that make endometrium receptive to implantation are gradually being recognized. Among these are the cytokines, integrins, heat shock proteins, tastin and trophinin. In addition, the expression of a second set of genes including tumour necrosis factor alpha (TNF-alpha) and ebaf, may be the appropriate signal for the closure of the 'implantation window', for making the endometrium refractory to implantation and for preparing it for the menstrual shedding.  (+info)

Changes in basement membrane thickness in the human endometrium during the luteal phase of the menstrual cycle. (3/4600)

We have examined aspects of the fine structure of the basal laminae associated with the luminal and glandular epithelium and small blood vessels in the human endometrium. Four short studies are presented and reviewed. Study 1 examined biopsies from 20 fertile women taken on days after the luteinizing hormone surge (LH): LH +2, 4, 6, 8 and 10. The basal lamina (both lamina densa and lucida) increased in thickness over the period studied. Study 2 again studied the glandular epithelium and examined the effect of RU486 (a progesterone receptor blocker) administered on day LH +3 and biopsied on day LH +6. The basal laminae were found to be the same as LH +2 control group but thinner than LH +6 control. Study 3 documented increased thickness of the basal laminae between LH +6, 8 and 13 in the luminal epithelium. The within-group coefficient of variation was 16% and 27% for LH +6 and LH +13 groups but only 2 % for LH +8. Study 4 demonstrated an increase in basal lamina thickness associated with small blood vessels between LH +6 and LH +10 in normal fertile women. The basal lamina provides the interface between epithelial and mesenchymal environments; changes in its structure can alter the phenotypic expression of the epithelia. It is one of the maternal barriers that must be transgressed by the trophoblast during implantation. Together, these combined studies provide quantitative baseline structural information on the electron microscopical appearance of the basal lamina during the luteal phase of the menstrual cycle.  (+info)

Endometrial oestrogen and progesterone receptors and their relationship to sonographic appearance of the endometrium. (4/4600)

The rapid development of ultrasonographic equipment now permits instantaneous assessment of follicles and endometrium. The sonographic appearance of the endometrium has been discussed in relation to in-vitro fertilization (IVF) cycles. However, a generally agreed view of the relationship of the sonographic appearance to fecundity in IVF cycles has not emerged. We have studied the relationship between steroid receptors and the sonographic appearance of the preovulatory endometrium in natural cycles and ovulation induction cycles. Preovulatory endometrial thickness was not found to be indicative of fecundity, although a preovulatory endometrial thickness of <9 mm related to an elevated miscarriage rate. The preovulatory endometrial echo pattern did not predict fecundity. No relationships were found among endometrial appearance, endometrial steroid receptors and steroid hormone concentrations in serum. Oestrogen or progesterone receptor concentrations were not related to endometrial thickness or to concentrations of serum oestradiol, the only significant correlation being found between the endometrial concentrations of oestrogen and progesterone receptors. The ratio of progesterone:oestrogen receptor concentration was somewhat less in echo pattern B (not triple line) endometrium compared with pattern A (triple line) endometrium. Oestrogen and progesterone receptor concentrations appeared stable on gonadotrophin induction, though fewer numbers were found during clomiphene cycles than in natural cycles. With regard to the distribution of receptor concentration between clomiphene and natural cycles, most women using clomiphene had very low oestrogen receptor populations. Pregnancy rates were low, in spite of high ovulatory rates during clomiphene treatment and were mainly related to low oestrogen receptor concentrations in preovulatory endometrium.  (+info)

Germ cell development in the XXY mouse: evidence that X chromosome reactivation is independent of sexual differentiation. (5/4600)

Prior to entry into meiosis, XX germ cells in the fetal ovary undergo X chromosome reactivation. The signal for reactivation is thought to emanate from the genital ridge, but it is unclear whether it is specific to the developing ovary. To determine whether the signals are present in the developing testis as well as the ovary, we examined the expression of X-linked genes in germ cells from XXY male mice. To facilitate this analysis, we generated XXY and XX fetuses carrying X chromosomes that were differentially marked and subject to nonrandom inactivation. This pattern of nonrandom inactivation was maintained in somatic cells but, in XX as well as XXY fetuses, both parental alleles were expressed in germ cell-enriched cell populations. Because testis differentiation is temporally and morphologically normal in the XXY testis and because all germ cells embark upon a male pathway of development, these results provide compelling evidence that X chromosome reactivation in fetal germ cells is independent of the somatic events of sexual differentiation. Proper X chromosome dosage is essential for the normal fertility of male mammals, and abnormalities in germ cell development are apparent in the XXY testis within several days of X reactivation. Studies of exceptional germ cells that survive in the postnatal XXY testis demonstrated that surviving germ cells are exclusively XY and result from rare nondisjunctional events that give rise to clones of XY cells.  (+info)

Genetic analysis of viable Hsp90 alleles reveals a critical role in Drosophila spermatogenesis. (6/4600)

The Hsp90 chaperone protein maintains the activities of a remarkable variety of signal transducers, but its most critical functions in the context of the whole organism are unknown. Point mutations of Hsp83 (the Drosophila Hsp90 gene) obtained in two different screens are lethal as homozygotes. We report that eight transheterozygous mutant combinations produce viable adults. All exhibit the same developmental defects: sterile males and sterile or weakly fertile females. We also report that scratch, a previously identified male-sterile mutation, is an allele of Hsp82 with a P-element insertion in the intron that reduces expression. Thus, it is a simple reduction in Hsp90 function, rather than possible altered functions in the point mutants, that leads to male sterility. As shown by light and electron microscopy, all stages of spermatogenesis involving microtubule function are affected, from early mitotic divisions to later stages of sperm maturation, individualization, and motility. Aberrant microtubules are prominent in yeast cells carrying mutations in HSP82 (the yeast Hsp90 gene), confirming that Hsp90 function is connected to microtubule dynamics and that this connection is highly conserved. A small fraction of Hsp90 copurifies with taxol-stabilized microtubule proteins in Drosophila embryo extracts, but Hsp90 does not remain associated with microtubules through repeated temperature-induced assembly and disassembly reactions. If the spermatogenesis phenotypes are due to defects in microtubule dynamics, we suggest these are indirect, reflecting a role for Hsp90 in maintaining critical signal transduction pathways and microtubule effectors, rather than a direct role in the assembly and disassembly of microtubules themselves.  (+info)

The Parkes Lecture. Heat and the testis. (7/4600)

The evidence for the lower temperature of the testes of many mammals is summarized, and the reasons suggested for the descent of the testes into a scrotum are discussed. Descriptions are given of the various techniques used for studying the effects of heat on the testis, whole body heating, local heating of the testes (by inducing cryptorchidism, scrotal insulation or immersion of the scrotum in a water bath), and heating of tissue or cell preparations in vitro. The effects of heat are discussed, effects on the testis (weight, histology, physiology, biochemistry and endocrinology), on the numbers and motility of spermatozoa in rete testis fluid and semen, on fertilizing ability of spermatozoa and on the subsequent development of the embryos produced when spermatozoa from heated testes are used to fertilize normal ova. The possible mechanisms for the damaging effects of heat are discussed, as well as the importance of heat-induced abnormalities in male reproduction in domestic animals and humans.  (+info)

Impact of market value on human mate choice decisions. (8/4600)

Mate choice strategies are a process of negotiation in which individuals make bids that are constrained by their status in the market place. Humans provide an unusual perspective on this because we can measure their explicitly expressed preferences before they are forced to make any choices. We use advertisements placed in newspaper personal columns to examine, first, the extent to which evolutionary considerations affect the level of competition (or market value) during the reproductively active period of people's lives and, second, the extent to which market value influences individual's willingness to make strong demands of prospective mates. We show that female market value is determined principally by women's fecundity (and, to a lesser extent, reproductive value), while male market value is determined by men's earning potential and the risk of future pairbond termination (the conjoint probability that the male will either die or divorce his partner during the next 20 years). We then show that these selection preferences strongly influence the levels of demands that men and women make of prospective partners (although older males tend to overestimate their market value).  (+info)

Natural fertility is the fertility that exists without birth control. The control is the number of children birthed to the parents and is modified as the number of children reaches the maximum. There is evidence that there is little birth control is used in non-European countries. Natural fertility tends to decrease as a society modernizes. Women in a pre-modernized society typically have given birth to a large number of children by the time they are 50 years old, while women in post-modernized society only bear a small number by the same age. However, during modernization natural fertility rises, before family planning is practiced. Historical populations have traditionally honored the idea of natural fertility by displaying fertility symbols. Natural fertility is a concept developed by the French historical demographer Louis Henry to refer to the level of fertility that would prevail in a population that makes no conscious effort to limit, regulate, or control fertility, so that fertility ...
Longer lives and fertility far below the replacement level of 2.1 births per woman are leading to rapid population aging in many countries. Many observers are concerned that aging will adversely affect public finances and standards of living. Analysis of newly available National Transfer Accounts data for 40 countries shows that fertility well above replacement would typically be most beneficial for government budgets. However, fertility near replacement would be most beneficial for standards of living when the analysis includes the effects of age structure on families as well as governments. And fertility below replacement would maximize per capita consumption when the cost of providing capital for a growing labor force is taken into account. Although low fertility will indeed challenge government programs and very low fertility undermines living standards, we find that moderately low fertility and population decline favor the broader material standard of living. ...
Downloadable! In this paper we analyze the distribution of fertility rates across the world using parametric mixture models. We demonstrate the existence of twin peaks and the division of the worlds countries in two distinct components: a high-fertility regime and a low fertility regime. Whereas the significance of twin peaks vanishes over time, the two fertility regimes continue to exists over the whole observation period. In 1950 about two thirds of the worlds countries belonged to the high-fertility regime and the rest constituted the low-fertility regime. By the year 2005 this picture has reversed. Within both the low- and the high-fertility regime the average fertility rate declined, with a larger absolute decline within the high-fertility regime. Visually, the two peaks moved closer together. For the low fertility-group we find both beta- and sigma- convergence but we cannot establish any convergence pattern for the high fertility regime. Overall our findings are difficult to reconcile with the
TY - JOUR. T1 - Contextual Understanding of Lower Fertility Among U.S. Women in Professional Occupations. AU - Shreffler, Karina M.. PY - 2017/1/1. Y1 - 2017/1/1. N2 - Despite decades of research indicating that employed women in the United States have fewer children than other women, it remains unclear what it is about work, beyond work hours, that constrains fertility. The current study links a sample of 1,800 women of childbearing age who are employed at least part-time from the National Survey of Fertility Barriers with the Department of Labors Occupational Information Network to examine how characteristics of womens jobs are associated with their fertility intentions and behaviors. Results indicate that women who work in more professional jobs (e.g., occupations with greater prestige, autonomy, complexity, and supervisory characteristics) are more likely to postpone childbearing than women employed in jobs with lower scores on professional characteristics. Women in more professional jobs ...
Total fertility rate in South Korea is the lowest in the world. A fertility rate below replacement fertility level will result in serious social problems in the long term. Therefore, it is worthwhile to study a general understanding about the low fertility rate phenomenon and to investigate the effectiveness of fertility policies in order to ameliorate the resulting social problems due to the low fertility rate. This research was a descriptive examination into the low fertility rate phenomenon and an investigation of the needs for fertility potties and their effectiveness. The study subjects were consisted of 769 unmarried people aged from 18 to 40 years old. Data were collected from June to August 2004 and were analyzed by frequencies, mean, and standard deviation. The following results were revealed. First, unmarried people in general had positive perspectives about getting marriaged, giving birth, and being a parent. In addition, the primary cause of low fertility rate was economical ...
This study investigated the relationships among parities and variance components in each parity for female fertility traits in Chinese Holsteins. In addition, the present study estimated genetic and phenotypic correlations between heifer traits and between cow traits. The results obtained from the present study will be useful for genetic evaluations in dairy cattle breeding programs, particularly for developing a routine genetic evaluation system for female fertility traits in Chinese Holstein population.. The average performances of fertility traits in the present study were similar to those of other populations in general [6, 12, 22]. It was also observed that all the fertility performances of heifers were better than those of cows, consistent with previous studies [23]. The differences in the reproductive physiology between maiden heifers and cows could be caused by first calving and the negative energy balance resulting from high milk yield [13]. In addition, the larger amount of censored ...
The experiment was conducted in split plot design with fifteen treatments combinations with three replications during rabi season 2018-19. The experiment consisted of three levels of fertility as main factor and five levels of organic sources assigning to sub-plots by replicating thrice. Three fertility levels were 75% recommended dose of fertilizers (RDF), 100% RDF (120:60:60 NPK) and 125% RDF. The five levels of organic sources were control, vermicompost @ 2.5 t ha-1, vermicompost @ 2.5 t ha-1 + Azotobacter + PSB, FYM (farmyard manures) @ 5 t ha-1 and FYM @ 5 t ha-1 + Azotobacter + PSB. Among fertility levels, the application of 100% RDF being at par with 125% RDF recorded maximum growth and yield attributes, grain (40.19 and 41.88 q ha-1, respectively) and straw (58.27 and 60.72 q ha-1, respectively) . Similarly, the application of FYM @ 5 t ha-1 being at par with vermicomposting @ 2.5 t ha-1

The fertility of an individual female is defined as the number of live births of babies to that female. Note that the term fertility rate is typically used when talking about aggregating fertility values across populations, but we simply talk of fertility when referring to a particular individual female. The fertility of an individual female is a nonnegative integer, i.e., it could take values 0, 1, 2, ... Due to biological considerations, it typically would not exceed 20 (there are only about 32 females in recorded history who have had more than 20 children, according to Wikipedias list of people with the most children). Fertility is a loose umbrella term. The more technical terms are described below. Note that in day-to-day parlance, fertility may be used in the sense of ability to produce children. In demographic jargon, we use the term fecundity for that sense of the word fertility, and reserve the use of the term fertility for actual children produced so far or in the future. ...
Recently, according to a weight loss news report, taking weight loss pills has a great impact on fertility, which may cause infertility. According to reports, various ingredients contained in weight loss medicines are at great risk to our body. Its important ingredient, fenfluramine , can cause h...
This paper reports the results of an empirical investigation of sampling fluctuations in age specific fertility rates (ASFR), total fertility rates (TFR), and the ratios of ASFRs used to identify the age pattern of childbearing (ASFR at age X/ASFR at age 20-24). Fertility parameters may be accurately estimated from birth histories collected from as few as 50 women.
Study Purpose: The surprisingly deep drop in Italian birth rates to among the lowest in the world (total fertility rate of 1.3 or below) has dramatically challenged existing social science theory by appearing to contradict population experts predictions of where such very low below replacement fertility would emerge. This interdisciplinary research project, known as ELFI (Explaining Low Fertility in Italy), has made considerable inroads into understanding the puzzle of lowest-low Italian fertility, reevaluating theories of reproduction and human behavior more generally. Through the use of innovative methodologies, an international team of collaborators from anthropology, sociology, and demography has produced key findings using both statistical, quantitative methods and extensive ethnographic, qualitative methods. Study Design: Four Italian cities were studied ethnographically by trained anthropologists. In each, both a working-class and a middle-class neighborhood were identified, and ...

Adult men with autoimmune conditions are commonly prescribed anti-tumor necrosis factor (anti-TNF) agents; however, there is a paucity of quality evidence as to their effect on male fertility (e.g. semen parameters and sperm quality). Our objective was to determine if men with autoimmune conditions are being counseled regarding the unknown reproductive effects of anti-TNF agents prior to initiation of therapy. A retrospective analysis of 1010 male patients age 18-45 who were prescribed an anti-TNF agent were assessed for (1) receipt of counseling regarding potential reproductive effects; (2) screening for anatomic or laboratory abnormalities associated with infertility; (3) election for sperm cryopreservation. Only 10.3% of men received counseling, and this was not associated with age (p = 0.77). Those who received counseling were significantly more likely to have a genitourinary exam performed, be assessed for presence of a varicocele, be asked about or endorse low libido or erectile dysfunction, have
Obesity: The obesity epidemic has recently become is a serious issue, particularly in industrialized nations. The rising number of obese individuals may be due in part to an energy-rich diet as well as insufficient physical exercise. In addition to other potential health risks, obesity can have a significant impact on male and female fertility. BMI (body mass index) may be a significant factor in fertility, as an increase in BMI in the male by as little as three units can be associated with infertility. Several studies have demonstrated that an increase in BMI is correlated with a decrease in sperm concentration, a decrease in motility and an increase DNA damage in sperm. A relationship also exists between obesity and erectile dysfunction (ED). ED may be the consequence of the conversion of androgens to estradiol. The enzyme aromatase is responsible for this conversion, and is found primarily in adipose tissue. As the amount of adipose tissue increases, there is more aromatase available to ...
The aim of the current study were two fold; Firstly to establish the mechanism and timing of occurrence of fertility parameters associated with the onset of puberty and to investigate the effects, mechanisms and mode of action of restricted energy intake on growth rate, and age at puberty. Secondly, to study the effects of mating at different intervals post-partum on early fertility parameters and to identify the fertility parameters affected by early remating in three breeds of rabbits - the Local Cameroonian, the Californian and the New Zealand. The effects of two energy levels of intake on the onset of puberty were investigated. The results showed that restricted energy intake had no effect on mating behaviour but that, a critical level of oestradiol 17? was necessary to render the pituitary sensitive to GnRH following mating. It also revealed that the effects of nutrition on fertility parameters at puberty were mediated through the body weights achieved. Both a critical concentration of ...
Downloadable! Starting from the assumption that economic insecurity is a key factor behind childbearing decisions, we empirically assess how fertility intentions are affected by job instability, which may severely compromise the employment status of workers, and economic disadvantages in terms of household income and wealth. We show that the instability of women�s work status (i.e. the holding of occasional and precarious jobs) significantly postpones maternity decisions for medium/high level income households; the chances of further childbirth are significantly and negatively affected by household income insecurity. Finally, low levels of household wealth influence the decision of having a first child.
To the Editors:. In sub-Saharan Africa, stable heterosexual HIV-1 serodiscordant couples (ie, one member is HIV-1 infected and the other uninfected) account for a substantial proportion of new infections and are a priority population for novel prevention interventions.1 Serodiscordant couples frequently have high pregnancy incidence and intentionally risk HIV-1 transmission to conceive.2,3 Earlier antiretroviral therapy (ART) initiation (ie, at CD4 counts ,350 cells/μL) substantially reduces the risk of HIV-1 transmission within HIV-1 serodiscordant couples.4 Early ART may reduce periconception HIV-1 transmission risk due to decreased HIV-1 viral load and infectiousness.5,6 We investigated fertility intentions and interest in early ART for HIV-1 prevention among East African HIV-1-infected individuals in serodiscordant partnerships.. Between July and December 2011, we conducted a cross-sectional study among Kenyan and Ugandan heterosexual HIV-1 serodiscordant couples participating in the ...
A life cycle model of fertility based on the quantity-quality model of fertility successfully explains changes in completed fertility in a period in which completed fertility first fell and then rose. This model furthermore accurately predicts the timing and level of the subsequent peak in completed fertility. Regressions based on Easterlins relative economic status theory of fertility are less successful in predicting fertility over a fifteen year period than regressions based on the quantity-quality model. Upon investigation, much of the increase in completed fertility associated with the baby boom appears to be primarily attributable to sporadic wage growth. ...
How Exactly Does Cannabis Affect Female Fertility?. We now have tackled the consequences of cannabis on male potency in a past post. Now, lets discuss exactly how it impacts the ladies..

Background: Literature is limited on the effects of high prevalence HIV on fertility in the absence of treatment, and the effects of the introduction of sustained access to antiretroviral therapy (ART) on fertility. We summarize fertility patterns in rural northeast South Africa over 21 years during dynamic social and epidemiological change. Methods: We use data for females aged 15-49 from the Agincourt health and socio-demographic surveillance system (1993-2013). We use discrete time event history analysis to summarize patterns in the probability of any birth. Results: Overall fertility declined in 2001-2003, increased in 2004-2011, and then declined in 2012-2013. South Africans showed a similar pattern. Mozambicans showed a different pattern, with strong declines prior to 2003 before stalling during 2004-2007, and then continued fertility decline afterwards. There was an inverse gradient between fertility levels and household socioeconomic status. The gradient did not vary by time or ...
When weighing the options, the pros and cons of intrauterine insemination (IUI) and in vitro fertilization (IVF) will, of course, be explored fully in discussion with your physician. In general terms, you can expect IUI to be a simpler process, less invasive, and lower cost. Some fertility specialists recommend attempting one or more cycles of artificial insemination before moving to IVF but this does not apply to everyone. For example, for an older woman, to try artificial insemination first may take up valuable time and the recommendation could well be to move straight to IVF. But before you can compare the two treatments, you need to know what exactly you could expect from IVF. ...
Analyzes the correlates of fertility levels in societies and childbearing among individuals and couples. Examines classical theories of fertility change at the societal level and contemporary critiques of these theories. Also examines the determinants of fertility at the individual level, with an emphasis on differences in the timing first birth and total family size by social class and ethnicity in developed and developing countries.
Schoen et al. (1999). 1. In what ways does Schoen et al.s study move ahead from prior research? How do their findings contradict those from previous studies?. 2. Schoen et al. state that it is important to distinguish the additional information effect and mediation effect of fertility intention. Why? What is the implication for this distinction?. 3. Does fertility intention have the same meaning as fertility desire?. 4. Schoen et al. summarized that fertility intention could be mediated by some variables (e.g. spouses intention, lifecycle factors and reproduction related changes), of which the individual has various degree of control. However, how can we understand the mediating factors that are out of an individuals control? (for example, one-child policy.). 5. According to Schoen et al.s regression results on married and unmarried persons, educational level is significant for unmarried persons, but loses its significance for married persons. How can we interpret this result?. 6. ...

Laptop computers are being studied in health circles because of their possible impact on fertility, particularly in men. Previous studies looked at the laptop as a heat source, raising the temperature of the scrotum and possibly damaging sperm in the process. A new study, conducted by Argentinian researchers at Nascentis Medicina Reproductiva, finds that another possible culprit to male infertility may be the Wi-Fi signal in their laptops.. Conrado Avendano MS and colleagues obtained semen samples from 29 healthy men and placed a few drops under a laptop connected to the Internet via Wi-Fi. After four hours, a quarter of the sperm showed a significant decrease in progressive sperm motility, compared to just 14% from semen samples stored at the same temperature away from the computer. This means that the sperm exposed to the signal were less capable of moving toward an egg to fertilize it. In addition, nine percent of the sperm samples showed DNA damage, three-fold more than the comparison ...
About her use of the FertiliCare Phase 1 & 2 Program, Emilie says, Had irregular cycles, with no ovulation. First month got my cycle down to 30 days, did not ovulate. Month two, ovulated and conceived. Would recommend this product. Was taking the lowest suggested dose. 30 drops twice a day.. Emilie wanted to share more of her story with you! Read more of her story below…. My cycles have been irregular for quite a while. I knew from research that this would indicate anovulation. Went to my GYN to see if there was possibly something wrong and what my next steps were. Blood work said there wasnt anything wrong. Great news, but I still wasnt ovulating or pregnant. Gyn said I needed to see a fertility specialist. I grappled with that idea for about a week and decided I was not going. I did not want that for my body. After reading many articles on Natural Fertility Info, I looked into the Fertilica FertiliCare Phase 1&2, as well as the Self Fertility Massage. My first cycle using the product ...
The study confirmed the UNAIDS assumptions of higher fertility for women 15-19 years old and lower fertility for women older than 20 years old for HIV-positive women in 20 national population-based surveys. The result also indicated that sexually active women with HIV infection had a lower fertility across all age groups compared with women who were sexually active but who were not infected with HIV. However, the analyses suggested that the previous assumptions, which set the ASFR ratio to 1.5 for 15-19 years and 0.7 for the remaining age groups,3 15 could be improved. We recommended an updated fertility adjustment, 1.2, 0.76, 0.71, 0.65, 0.59, 0.53 and 0.47, for each 5-year age bracket from 15-19, 20-24, 25-29, 30-34, 35-39, 40-44 and 45-49 years old, respectively. In addition, we proposed that the ASFR ratio in the 15-19-year-old age group should be adjusted based on the proportion of sexually active women in that age group if country-specific information is available.. One major concern of ...

The impact of persistent organochlorine pollutants (POPs)[4], of which PCBs and DDT are two, on human fertility is still unknown and there are limited and contradictory findings so far as to whether PCBs and DDT/DDE damage human sperm. This study, which is part of a wide-ranging project known as INUENDO[5], set out also to see whether these two POPs damage sperm by altering its chromatin integrity. (Chromatin is the DNA and associated proteins that make up a chromosome ...
Talk to your doctor or OB/GYN or fertility specialist. If you have questions about your reproductive health you should discuss your options with your doctor, OB/GYN, or a fertility specialist (like AZCREI). There are many health conditions that impact fertility, including hormone imbalances, PCOS, thyroid disorders, uterine fibroids, damage to the fallopian tubes, endometriosis, and STIs. Age, BMI, and your family medical history can all affect fertility as well. You may want to write down your questions ahead of time, before your visit, so you can get all the answers you need to create a plan for your next steps.. Evaluate your lifestyle and habits. A chat with your doctor may spur you to evaluate a few of your lifestyle choices and habits. Since BMI can affect fertility, you may want to gain or lose weight before you start trying to conceive in order to increase your chances of a successful pregnancy. Exercise, regardless of your BMI, is also important for your general health. If you smoke, ...
Diagnosis of male infertility has been based mainly on the traditional semen parameters (concentration, motility and morphology). Historically, the semen analysis results are the foundation on which clinicians base their decision for treatment for a given couple. It has, however, become clear that semen parameters are insufficient for the determination of male fertility potential. A continuous search for better markers of male fertility has led to an increased focus on testing of sperm chromatin integrity in fertility workup and ART. Sperm DNA damage is a useful biomarker for male infertility diagnosis and prediction of assisted reproduction outcomes. It is associated with reduced fertilization rates, embryo quality and pregnancy rates, and higher rates of spontaneous miscarriage and childhood diseases. Successful fertilization of the human oocyte from spermatozoa with damaged DNA may lead to paternal transmission of defective genetic material with adverse consequences to embryo development. ...
August 26, 2011. By Patricia Nicholson. A new study of cancer survivors suggests that chemotherapy may affect womens fertility, even if their periods return after treatment. Many women undergoing chemotherapy experience amenorrhea, meaning that their periods stop during treatment. In most cases, their periods return within one year, especially in younger women. However, some women experience permanent ovarian failure. A study of more than 600 cancer survivors found that even among those whose periods returned, women who had undergone chemotherapy were at increased risk for infertility and early menopause.. Researchers at the University of California at San Francisco School of Medicine surveyed 620 women who were diagnosed with cancer between the ages of 18 and 40. All of the women had been treated with chemotherapy alone (not with pelvic radiation, pelvic surgery or bone marrow transplants that may affect fertility). The women were treated for either Hodgkins disease, non-Hodgkins lymphoma, ...

Abstract. Infertility is an important aspect of human and animal reproduction and still presents with much etiological ambiguity. As fifty percent of infertility is related to the male partner, molecular investigations on sperm and seminal plasma can lead to new knowledge on male infertility. Several comparisons between fertile and infertile human and other species sperm proteome have shown the existence of potential fertility markers. These proteins have been categorized into energy related, structural and other functional proteins which play a major role in sperm motility, capacitation and sperm-oocyte binding. The data from these studies show the impact of sperm proteome studies on identifying different valuable markers for fertility screening. In this article, we review recent development in unraveling sperm fertility related proteins.. Keywords: proteomics, sperm, fertility, protein, infertility. ...

The total of the answers to the questions relating to living children, present and absent, provides the total number of children born and surviving; adding the reported numbers of children dead gives the total number of children ever born to the woman. When summing these individual answers, care must be taken not to treat error or missing value codes as legitimate responses. For example, if a missing value is coded as 9, the process of deriving measures of the total children ever born, surviving and dead must make sure to exclude these codes.. It is not uncommon for the total number of children ever born to be truncated at some relatively high number (e.g. 11+). When this is the case, the only plausible assumption is that women in that category have had the lower bounds number of children. The resulting errors are generally small, except in the case of extremely high fertility and, even then, only at the oldest ages.. In evaluating the quality of data on lifetime fertility, the analyst should ...
By definition, Azoospermia means that a man does not have a measurable amount of sperm in his ejaculate. The condition is typically diagnosed when a patient and their partner are experiencing difficulty conceiving and seek testing and diagnosis from a fertility specialist. A semen analysis will be performed in order to determine the number of viable sperm found in the male patients ejaculate. If virtually no sperm is found, your doctor may suggest additional testing as necessary2 (Jarow et al. 2011. AUA). This testing can include a semen analysis at a fertility laboratory such as The Fertility Center of California (FCC), the partner laboratory of The Male Fertility Specialists. A fertility lab, like FCC, with a technique called high speed centrifugation (HSC), a few sperm can often be found that may have been missed by testing in some of the larger, less-specialized laboratories or by at-home sperm count tests. Indeed, HSC can find sperm in approximately 15% of specimens initially thought to ... offers information about fertility and fertility treatments but this information should not be used as medical advice.

85 George E. Mann PROGESTERONE AND FERTILITY George E. Mann1 ABSTRACT Fertility in the modern dairy cow is currently low and appears to be declining. Poor fertility is due to a number of factors, one of which is inadequate progesterone secretion by the mother during early pregnancy. While the reasons for poor progesterone secretion are still to be fully elucidated a number of factors have been implicated. Treatment with progesterone can yield improvements in pregnancy rate but it is important to ensure that treatment is administered at an appropriate time and targeted at those cows that actually need it. INTRODUCTION In the wild ancestors of the modern dairy cow fertility is high, with first service pregnancy rates approaching 90% leading to most cows calving within an 8 week period. Despite continued efforts to improve fertility, these figures represent little more than a dream to the modern dairy farmer. Poor fertility is a major problem and in many countries is approaching a level where ...

This research details the influence of fertility on plant growth, photosynthesis, ethylene evolution and herbivore abundance of chrysanthemum (Dendranthema grandiflora Tzvelev `Charm) inoculated with cotton aphids (Aphis gossypii Glover). We tested five fertility levels that consisted of 0%, 5%, 10%, 20%, and 100% (375 ppm N) of recommended nitrogen levels. Aphid abundance was greatest at high fertility. Fertility affected the vertical distribution of aphids. A higher population of aphids were observed in physiologically mature and older leaves at low fertility, whereas at high fertility young leaves had 33% more aphids than older, basal leaves. Aphids depressed plant vegetative and reproductive growth, and altered carbohydrate partitioning at high fertility. Aphid-inoculated (AI) plants at high fertility had increased specific leaf area [(SLA), i.e., thinner leaves] and greater leaf area than aphid-free (NonAI) plants. Aphids caused greater ethylene production in reproductive buds and young ...

Present study was conducted on 53 healthy cyclic cow of 2-5 parity and ,90 day postpartum to evaluate the efficacy and subsequent fertility of three estrus synchronization protocols i.e. CIDR-PG (n=13), Ovsynch (n=15), Heatsynch (n=15). The animals of control group (n=10) remained untreated. After end of the protocol all the treated cows were observed daily morning-evening for 7 days for the occurrence of signs of estrus and inseminated artificially 12 to 18 hrs after the onset of estrus. Cohort development of developing follicles (5 mm) was monitored by ...
Poking around Google Data Explorer I reacquainted myself with an interesting fact: though the teen birth rate in Bangladesh is greater than that in Pakistan, the total fertility rate is far lower. The disjunction has emerged over the last generation, as Bangladeshs TFR has dropped much faster than Pakistans. To the left you see a scatter plot, which shows teen fertility rates (age 15-19) as a function of total fertility rates. Ive labeled a few nations, and also added the color coding by region. It is notable that the nations above the trend line seem to be Latin American, while those below are disproportionately Middle Eastern. That means that Latin American nations have higher teen fertility in relation to their total fertility, while Middle Eastern nations have lower teen fertility in relation to their total fertility. Sweden actually has a rather high fertility rate in relation to its teen birth rate. The expectation is generated by world wide patterns, so I thought Id look more closely ...

30] Studies of actual couples trying to conceive have come up with higher results: one 2004 study of 770 European women found that 82% of 35- to 39-year-old women conceived within a year,[31] while another in 2013 of 2,820 Danish women saw 78% of 35- to 40-year-olds conceive within a year.[32] The use of fertility drugs and/or invitro fertilization can increase the chances of becoming pregnant at a later age.[33] Successful pregnancies facilitated by fertility treatment have been documented in women as old as 67.[34] Studies since 2004 now show that mammals may continue to produce new eggs throughout their lives, rather than being born with a finite number as previously thought. Researchers at the Massachusetts General Hospital in Boston, US, say that if eggs are newly created each month in humans as well, all current theories about the aging of the female reproductive system will have to be overhauled, although at this time this is simply conjecture.[35][36] According to the March of Dimes, ...
This paper illustrates evolutionary approaches to population issues. Life history theory is a general theoretical framework that incorporates environmental influences, contextual influences, and heritable variation. In general, physically or psychologically stressful environments delay maturation and the onset of reproductive competence. Perceptions of scarcity also result in lower fertility by delaying reproduction or having fewer children-a phenomenon viewed as an adaptation to ancestral environments. The desire for upward social mobility is viewed as an evolved motive disposition affecting fertility decisions. The opportunity for upward social mobility typically results in delaying reproduction and lowering fertility in the interest of increasing investment in children. Variation in life history strategies is also influenced by genetic variation, but genetic variation interacts with cultural shifts in the social control of sexual behavior. Finally, I discuss the effects of between-group ...

According to new a report release by the National Center for Health Statistics, fertility rates in the United States are continuing to decline and we have now reached a point where the number of new babies born is below whats needed for the population to replace itself.. For the population to be able to replace itself, the total fertility rate needs to be 2,100 births per 1,000 women of childbearing age over their lifetime. But, according to the new report, the total fertility rate in 2017 was 1,765.5 births per 1,000 women. In 2016, it was 1,820.5 births per 1,000 women. The total fertility rate has been declining for the past seven years, but the 2017 numbers show the biggest drop in recent history.. While this information may sound grim, it it not necessarily a picture of doom. Fertility rates were bound to decline after the peak rates that were seen during the time of the baby boom generation. So, this is not unexpected news. In addition, year after year, we have been seeing a decline in ...

that a medication has that is not its primary intended effect. In this sense, nearly every type of medication has some side effect or another. Fertility drugs are no exception.. Fertility drugs generally come into two types. The first type, which is given in the form of a pill, would include drugs such as Clomid. Other types of fertility drugs are typically injected, such as Repronex, Follistim, Pergonal, Repronex, and Gonal-F. In general, the injectible fertility medications tend to have fewer side effects than pill fertility drugs.. One side effect that is common in both types of fertility drugs is the risk of multiple births. In somewhere around half of cases, fertility drugs lead to a pregnancy with twins or multiples. Multiple births and multiple pregnancies carry with them certain inherent risks, which should be discussed with your health care provider before starting fertility drugs.. Another concern with fertility drugs is the risk of ovarian cancer. There is some research to suggest ...
p,Fertility, being a major study unit in population dynamics, should be analyzed from different perspectives as it plays a pivotal role in understanding the complex issues integral to population growth. The main objective of this study was, therefore, to understand what the micro level major socio - economic determinants of fertility are in the case of urban Ethiopia. Count data models were used to estimate fertility, given by the number of children ever born by a woman, using the Ethiopian Demographic and Health Survey (EDHS) data of 2005. The main findings of the study showed that education, age at first marriage, labor force participation and wealth status of women are negatively related to fertility while child mortality was not found to be a significant determinant of fertility. The findings of the study revealed that fertility decision is influenced by various socio-economic variables and, hence, achieving a low level of fertility rate requires an all rounded sustainable development ...
Apr 28 2017, 9:00 AM When a man is diagnosed with testicular cancer, providers work quickly to begin treatment. In this fast process, one big concern can move down the list of priorities: fertility. While men of all ages can have testicular cancer, it is the most common cancer for men in their teens, 20s, and 30s, and men in this age group may want to have children someday.. For some, fertility is impacted during treatment but returns when treatment ends. For others, the effects on fertility are permanent. It is important to ask your doctor about the impact treatment can have on your fertility before treatment begins.. Fertility in men with testicular cancer can be affected by several things:. ...
Major Finding: Many oncologists are not likely to mention fertility preservation to cancer patients who have a poor prognosis, contrary to guidelines.. Data Source: A national 53-item survey of 513 U.S. oncologists.. Disclosures: The study was sponsored by the American Cancer Society. Dr. Quinn and her associates stated that they have no conflicts of interest.. ATLANTA - Physicians attitudes may conflict with recommended guidelines for fertility preservation and reduce the likelihood that cancer patients will receive information about this reproductive option.. That conclusion was drawn from a national 53-item survey of 513 U.S. oncologists, specifically examining physicians attitudes toward fertility preservation referral among cancer patients with a poor prognosis.. Sixty percent of respondents agreed with the statement that fertility preservation is a high priority for me to discuss with newly diagnosed cancer patients, while 26% were unsure and 14% disagreed, Gwendolyn Quinn, Ph.D., and ...
The following are the fertility drugs which are the best treatment for the women who are infertile due to ovulation disorder and these are:. a) Clomid: Clomid is a fertility drug which is taken by mouth and stimulates ovulation by causing the pituitary gland to release more FSH (Follicle-stimulating hormone) and LH (Luteinizing hormone) so that it will stimulate the growth of an ovarian follicle that is containing an egg.. b) Metformin: Metformin is a fertility drug which is given to women when insulin resistance is a known or suspected cause of infertility. Usually, the fertility experts at Fertility Center Nepal recommend Metformin to the women who diagnosed with PCOS. Metformin is a fertility drug which helps in improving insulin resistance and also it will help in improving the likelihood of ovulation.. c) Gonadotropins: Gonadotropins is an injectable fertility drug which is given to the women so that it will directly stimulate women ovaries to produce multiple eggs, instead of stimulating ...
BackgroundThere is growing recognition of the difficult reproductive decisions faced by HIV-positive women. Studies in both resource-constrained and developed countries have suggested that many HIV-positive women continue to desire children in spite of their understanding of the possible risks that HIV poses. This study investigates the factors associated with fertility desire among HIV-positive women in Tigray region, Ethiopia.MethodsA cross-sectional survey was conducted among 964 HIV-positive women receiving HIV care in 12 health centers of Tigray region. In each health center, the number of study participants was allocated proportionally to the load of HIV-positive women in the chronic care clinics. A descriptive summary of the data and a logistic regression model were used to identify factors associated with fertility desire using odds ratios with a 95% confidence interval and P-value of 0.05.ResultsFour hundred and thirty nine (45.5%) of the participants reported a desire to have children ...

The aim of any holistic treatment which is addressing fertility is to help to create and maintain a healthy environment within the uterus for foetal development. Fertility Reflexology can help to facilitate this state of homeostasis by balancing hormones which then in turn helps to reduce the impact of any menstrual irregularity.. Stress can be one of the most significant factors impacting upon fertility. Anxiety around fertility can cause huge amounts of stress which can be a cause of infertility. Often women struggling with fertility will have visited medical doctors on a number of occasions and will have had numerous investigative tests, whilst also monitoring their own menstrual cycle which leads to a vicious cycle.. The reason for stress and anxiety having such an impact upon fertility is because this leads to an elevation of stress hormones in the body which includes adrenaline, norepinephrine and cortisol, which are both produced by the adrenal glands. These stress hormones then divert ...
Using U.S county level data on lead in air for 1978-1988, this paper provides the first causal evidence on the effects of airborne lead exposure on the general fertility rate and the completed fertility rate in the broad population. Instrumental variable estimates show the increase in completed fertility implied by the average observed decrease in airborne lead is 0.14 children per woman, which is 6.4 percent of mean fertility. To explore the current relevance of our findings, we estimate the effect of lead historically accumulated in topsoil on fertility in the 2000s. The results suggest that lead may continue to impair fertility today, both in the United States and in other countries that have significant amounts of lead in topsoil. ... stock an extensive range of natural fertility products for both men and women available in many forms including tablet, capsule, sprays and liquids.

Marijuana use affects fertility treatment outcomes Fri Mar 31, 2006 By Will Boggs, MD NEW YORK (Reuters Health) - The likelihood of a good outcome of fertility treatment is reduced if either the man or the woman uses marijuana, compared with couples that dont use it, the results of a new study suggest. If these study findings are confirmed by additional research, we would recommend that physicians tell couples to not use marijuana for at least one year before starting fertility
Presented in Session 144: Timing of Fertility.) Iraqs fertility transition is largely undocumented. This paper provides a detailed account of recent fertility trends in the country, with a particular focus on the changes resulting from the 2003-2011 war and the factors underlying them. The study is based on retrospective birth history data from the 2006 and 2011 Iraq Multiple Indicator Cluster Surveys. Estimates from the two surveys indicate that total fertility remained stable from 1997 to 2010 at a rate of about 4.5 children per woman. However, an examination of the age patterns of fertility reveals an abrupt shift in the timing of births, with adolescent fertility rising by over 30% soon after the onset of the war. A decomposition analysis shows that the rise in early childbearing is due to an increased prevalence of early marriage among the less educated. These findings have serious implications for womens health and empowerment in Iraq and similar war-affected settings.. ...
There are many fertility clinic options in New York city and surrounding boroughs. Choosing one may seem rather difficult. One way to begin comparing the fertility clinics is to look at their success rates. Fertility clinic success rates for New York City fertility clinics, as well as for clinics across the United States, can be found in the Assisted Reproductive Technology (ART) Report. The ART Report, which is compiled by the CDC, lists success rates for every fertility clinic in the United States for IVF procedures using fresh and frozen non-donor eggs, and fresh and frozen donor eggs. The success rates for non-donor egg IVF cycles are broken out by age group.
Before you begin fertility care at The Fertility Institute, you will meet with one of our doctors to determine which services and treatments are right for you.

For the female, these tests may include a hormonal evaluation and the examination of the physical integrity and structure of the ...
We know that certain chemicals can adversely affect sperm development (spermatogenesis) and lower sperm counts. Long-term exposure to these chemicals can cause irreversible damage; however, removing the toxin can often restore fertility.. Accidental and medically prescribed exposure to large amounts of radiation to the gonads (to combat a malignant tumor, for example) can also impair sperm production. If the tissue damage is not extensive, however, some degree of fertility may regenerate. We also know that excessive exposure to heat can interfere with sperm production. One reason that the sperm-producing testicles are located in the scrotum is to lower their temperature one or two degrees below the bodys. Some jobs may overheat the scrotum for example, the foundry worker or the sedentary long-distance truck driver. Oligozoospermia in the wheelchair-bound paraplegic also may be due to excessive scrotal heat. Removal of the heat exposure will usually resolve this type of fertility problem.. If ...
