A major gonadotropin secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). Luteinizing hormone regulates steroid production by the interstitial cells of the TESTIS and the OVARY. The preovulatory LUTEINIZING HORMONE surge in females induces OVULATION, and subsequent LUTEINIZATION of the follicle. LUTEINIZING HORMONE consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is common in the three pituitary glycoprotein hormones (TSH, LH and FSH), but the beta subunit is unique and confers its biological specificity.

The techniques used to select and/or place only one embryo from FERTILIZATION IN VITRO into the uterine cavity to establish a singleton pregnancy.
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.

Ontogeny of expression of a receptor for platelet-activating factor in mouse preimplantation embryos and the effects of fertilization and culture in vitro on its expression. (1/4970)

Platelet-activating factor (PAF; 1-o-alkyl-2-acetyl-sn-glycero-3-phosphocholine) is a potent ether phospholipid. It is one of the preimplantation embryo's autocrine growth/survival factors. It may act via a G protein-linked receptor on the embryo; however, the evidence for this is conflicting. The recent description of the intracellular form of the PAF:acetlyhydrolase enzyme as having structural homology with G proteins and Ras also suggests this as a potential intracellular receptor/transducer for PAF. This study used reverse transcription-polymerase chain reaction to examine the ontogeny of expression of the genes for these proteins in the oocyte and preimplantation-stage embryo. Transcripts for the G protein-linked PAF receptor were detected in the late 2-cell-stage embryo and in all stages from the 4-cell stage to blastocysts. They were also present in unfertilized oocytes and newly fertilized zygotes but only at relatively low levels. The incidence of expression was generally low and variable in late zygotes and early 2-cell embryos. Expression past the 2-cell stage was alpha-amanitin sensitive. The results indicated that mRNA for this receptor is a maternal transcript that was degraded during the zygote-2-cell stage. New expression of the receptor transcript required activation of the zygotic genome. Fertilization of embryos in vitro caused this transcript not to be expressed in the zygote. Culture of zygotes (irrespective of their method of fertilization) caused expression from the zygotic genome to be retarded by more than 24 h. This retardation did not occur if culture commenced at the 2-cell stage. The transcripts for the subunits of intracellular PAF:acetylhydrolase were not detected in oocytes or at any stage of embryo development examined, despite their being readily detected in control tissue. This study confirms the presence of the G protein-linked PAF receptor in the 2-cell embryo and describes for the first time its normal pattern of expression during early development. The adverse effects of in vitro fertilization (IVF) and embryo culture on the expression of this transcript may be a contributing factor for the poor viability of embryos produced in this manner. The reduced expression of PAF-receptor mRNA following IVF predicts that such embryos may have a deficiency in autocrine stimulation and also suggests that supplementation of growth media with exogenous PAF would be only partially beneficial. The effect of IVF and culture may also explain the conflicting literature.  (+info)

An intact sperm nuclear matrix may be necessary for the mouse paternal genome to participate in embryonic development. (2/4970)

We have been interested in determining the minimally required elements in the sperm head that are necessary in order for the paternal genome to participate in embryogenesis. We used an ionic detergent, mixed alkyltrimethylammonium bromide (ATAB), plus dithiothreitol (DTT) to remove the acrosome and almost all of the perinuclear theca, leaving only the sperm nucleus morphologically intact. We also tested the stability of the sperm nuclear matrix by the ability to form nuclear halos. Sperm nuclei washed in freshly prepared 0.5% ATAB + 2 mM DTT completely decondensed when extracted with salt, but nuclei washed in the same buffer that was 1 wk old, and then extracted with salt, produced nuclear halos, indicating stable nuclear matrices. When we treated sperm heads with freshly prepared ATAB+DTT and injected them into oocytes, none of the oocytes developed into live offspring. In contrast, sperm heads treated in the same way but with 1-wk-old ATAB+DTT solution could support development of about 30% of the oocytes to live offspring. Electron microscopy demonstrated that most of the perinuclear theca had been removed in both cases. These data suggest that at least in the mouse, the only component of the spermatozoa that is crucial for participation in embryologic development is the sperm nucleus with a stable nuclear matrix.  (+info)

Endometrial oestrogen and progesterone receptors and their relationship to sonographic appearance of the endometrium. (3/4970)

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)

Expression of CD44 in human cumulus and mural granulosa cells of individual patients in in-vitro fertilization programmes. (4/4970)

CD44 is a polymorphic and polyfunctional transmembrane glycoprotein widely expressed in many types of cells. Here, the expression of this protein on human membrana granulosa was studied by two techniques. Using confocal laser scanning microscopy (CLSM) with the mouse monoclonal antibody to human CD44 (clone G44-26), cells immunoreactive for CD44 were observed in both cumulus and mural granulosa cell masses. On the other hand, using monoclonal antibody to human CD44v9, goat polyclonal antibody to human CD44v3-10 and the clone G44-26, no immunoreactivity for CD44v9 and/or CD44v3-10 was observed in either cell group by flow cytometry. In the flow cytometric analysis of 32 patients, the incidence of CD44 expression in cumulus cells (62.6+/-1.3%) was significantly higher than that in mural granulosa cells (38.5+/-3.2%) (P<0.0001). In the comparison of CD44 expression by flow cytometry according to the maturation of each cumulus-oocyte complex, the incidence of CD44 expression of cumulus cells was significantly higher in the mature group than in the immature group (P<0.05). In a flow cytometric analysis, patients with endometriosis showed a significantly lower incidence of CD44 expression in cumulus cells compared to the infertility of unknown origin group (P<0.05), and compared to both the male infertility group and the unknown origin group in mural granulosa cells (P<0.01). These findings suggest that the standard form of CD44 is expressed in human membrana granulosa with polarity and may play an important role in oocyte maturation.  (+info)

Origin of DNA damage in ejaculated human spermatozoa. (5/4970)

The molecular basis of many forms of male infertility is poorly defined. One area of research that has been studied intensely is the integrity of the DNA in the nucleus of mature ejaculated spermatozoa. It has been shown that, in men with abnormal sperm parameters, the DNA is more likely to possess strand breaks. However, how and why this DNA damage originates in certain males and how it may influence the genetic project of a mature spermatozoon is unknown. Two theories have been proposed to describe the origin of this DNA damage in mature spermatozoa. The first arises from studies performed in animal models and is linked to the unique manner in which mammalian sperm chromatin is packaged, while the second attributes the nuclear DNA damage in mature spermatozoa to apoptosis. One of the factors implicated in sperm apoptosis is the cell surface protein, Fas. In this review, we discuss the possible origins of DNA damage in ejaculated human spermatozoa, how these spermatozoa arrive in the ejaculate of some men, and what consequences they may have if they succeed in their genetic project.  (+info)

In-vitro fertilization and culture of mouse embryos in vitro significantly retards the onset of insulin-like growth factor-II expression from the zygotic genome. (6/4970)

In this study, the effect of in-vitro fertilization (IVF) and culture of mouse embryos in vitro on the normal expression of insulin-like growth factor-II (IFG-II) ligand and receptor was examined. The expression of IGF-II increased in a linear fashion at least up to the 8-cell stage of development. IGF-II expression in embryos collected fresh from the reproductive tract was significantly (P < 0.001) greater than in embryos fertilized in the reproductive tract and cultured in vitro (in-situ fertilized: ISF), and its expression was further reduced (P < 0.001) in IVF embryos at all development stages tested. The expression of IGF-II was significantly (P < 0.001) lower when embryos were cultured individually in 100 microl drops compared with culture in groups of 10 in 10 microl drops of medium. The addition of platelet activating factor to culture medium partially overcame this density-dependent decline of expression. Culture of ISF and IVF zygotes also caused the onset of new IGF-II mRNA transcription from the zygotic genome to be significantly (P < 0.001) retarded, until at least the 8-cell stage of development. This effect was greater (P < 0.05) for IVF than for ISF embryos. Neither IVF nor culture had any obvious effect on IFG-II/mannose-6-phosphate receptor (IGF-IIr) mRNA expression.  (+info)

Detection of benzo[a]pyrene diol epoxide-DNA adducts in embryos from smoking couples: evidence for transmission by spermatozoa. (7/4970)

Tobacco smoking is deleterious to reproduction. Benzo[a]pyrene (B[a]P) is a potent carcinogen in cigarette smoke. Its reactive metabolite induces DNA-adducts, which can cause mutations. We investigated whether B[a]P diol epoxide (BPDE) DNA adducts are detectable in preimplantation embryos in relation to parental smoking. A total of 17 couples were classified by their smoking habits: (i) both partners smoke; (ii) wife non-smoker, husband smokes; and (iii) both partners were non-smokers. Their 27 embryos were exposed to an anti-BPDE monoclonal antibody that recognizes BPDE-DNA adducts. Immunostaining was assessed in each embryo and an intensity score was calculated for embryos in each smoking group. The proportion of blastomeres which stained was higher for embryos of smokers than for non-smokers (0.723 versus 0.310). The mean intensity score was also higher for embryos of smokers (1.40+/-0.28) than for non-smokers (0.38+/-0.14; P = 0.015), but was similar for both types of smoking couples. The mean intensity score was positively correlated with the number of cigarettes smoked by fathers (P = 0.02). Increased mean immunostaining in embryos from smokers, relative to non-smokers, indicates a relationship with parental smoking. The similar levels of immunostaining in embryos from both types of smoking couples suggest that transmission of modified DNA is mainly through spermatozoa. We confirmed paternal transmission of modified DNA by detection of DNA adducts in spermatozoa of a smoker father and his embryo.  (+info)

Fertilization, embryonic development, and offspring from mouse eggs injected with round spermatids combined with Ca2+ oscillation-inducing sperm factor. (8/4970)

Round spermatids, precursor male gametes, are known to possess the potential to achieve fertilization and embryonic development when injected into eggs. However, injection of spermatids alone seldom activates eggs in the mouse, as spermatids by themselves cannot induce an increase in intracellular Ca2+, a prerequisite for egg activation. We injected a mouse round spermatid into an egg simultaneously with partially purified sperm factor from differentiated hamster spermatozoa. The combined injection produced repetitive Ca2+ increases (Ca2+ oscillations) lasting for at least 4 h as observed at fertilization, and induced activation in 92% of eggs. This method provided 75% fertilization success associated with male and female pronucleus formation and development to 2-cell embryos, while only 7% of eggs were fertilized by injection of a spermatid alone. Of the 2-cell embryos, approximately 50% developed to blastocysts during 5 days of culture in vitro, while no blastocysts were obtained following injection of sperm factor alone. Furthermore, the 2-cell embryos, that were created by spermatids and sperm factor and transplanted into foster mothers, developed into normal offspring, although the percentage was only 22%. All infants grew into healthy adults carrying normal chromosomes. The sperm factor served as a complementary factor for successful fertilization by round spermatid injection.  (+info)

One of the leading decisions infertile patients need to make is - The way to select an excellent In vitro fertilization treatments clinic?

In an In Vitro Fertilization (IVF) cycle super ovulating drugs (gonadotropins) are usually taken to stimulate the ovaries to produce more than one egg. In Vitro Fertilization protocols are constantly under review in order to improve the recruitment of the follicles, which contain the eggs, whilst minimizing the doses of gonadotrophins required, with the ultimate aim of increasing the live birth rate.. The addition of growth hormone, which is a biological hormone that can be synthetically produced, as a supplement to gonadotrophins in an In Vitro Fertilization cycle has been suggested as a way in which In Vitro Fertilization pregnancy rates may be increased.Growth hormone has been shown, in animal and human studies, to be important in the recruitment of follicles.However, to date, only a limited number of clinical studies have been performed in order to assess whether the addition of growth hormone can improve the probability of pregnancy in women undergoing ovarian stimulation for In Vitro ...

article{3bac4e34-79d1-4847-855e-3a895175d0af, abstract = {Background. To evaluate the relationship between age and poor ovarian response to pregnancy and cancellation rate after IVF stimulation. Methods. Poor ovarian response was defined as <= 5 follicles at ovum pick up (OPU). Out of 1,706 consecutive OPUs performed during 2003/2004, 290 poor responders were identified. This cohort of poor responders was divided into two groups, older and younger, with a cut-off at the median age of 37 years. The pregnancy and cancellation rates after OPU were analysed. Results. Women aged > 37 years, who were poor responders, had a significantly lower pregnancy rate per OPU (3.0%) compared to normal to high responders in the same age group (22.1%, p < 0.05). Also, 43.6% of women > 37 years, who were classified as poor responders, did not receive an embryo transfer ( ET), compared to 13.2% of normal to high responders in this age group ( p < 0.05). Poor responders who were 5/37 years had a ...
According to a study a genetic-screening test is likely to increase chances of pregnancy for women using in-vitro fertilization (IVF).
The aim of this meta-analysis was to evaluate the effect of growth hormone (GH) supplementation in poor responders undergoing in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI). PubMed, MEDLINE and Cochrane Library databases were searched for the identification of relevant randomized controlled trials. Outcome measures were live birth rate, clinical pregnancy rate, miscarriage rate, cycle cancelation rate, number of retrieved oocytes and total dose of gonadotropin. Fifteen randomized controlled trails (RCTs) involving 1448 patients were eligible for the analysis. GH supplementation improved live birth rate (RR, 1.74; 95% CI, 1.19-2.54), clinical pregnancy rate (RR, 1.65; 95% CI, 1.31-2.08) and retrieved oocytes number (SMD, 0.72; 95% CI, 0.28-1.16), while reducing cancelled cycles rate (RR, 0.62; 95% CI, 0.44-0.85) and dose of Gonadotropin (SMD,-1.05 95% CI, − 1.62 - -0.49) for poor ovarian response patients. Besides, there was no significant difference in the miscarriage rate

In Vitro Fertilisation (IVF) and Intracytoplasmic Sperm Injection (ICSI) Melbourne. IVF produces good results for couples with male infertility treated by Dr Barak.. Standard IVF procedures produce good fertilisation rates unless the sperm morphology, motility or concentration is very low, or there are sperm antibodies or specific problems with the fertilisation process. For severe semen disorders, for example, if there are less than 2 million normal motile sperm in the semen, sperm morphology is ,95% abnormal or sperm are obtained from above obstructions in the genital tract there is a substantial chance of failure of fertilisation with standard IVF. In these situations ICSI is used to improve the chances of fertilisation occurring.. ICSI is now the method of choice for treating severe sperm problems. With this technique a single sperm is injected into the substance (cytoplasm) of each oocyte with a fine glass needle. This procedure may also be applied in situations where fertilisation could ...
In vitro fertilization is an assisted reproductive technology (ART), which involves retrieving eggs from a womans ovaries and fertilizing them with sperm in vitro. The process involves stimulating a womans ovulatory, removing an ovum from the womans ovaries, and letting sperm fertilize them in a liquid in a laboratory.

Treating Infertility: In Vitro Fertilization. In our last post,[1] we discussed the difference between infertility and impotence, stressing that infertility is not an impediment to marriage and that infertile couples can still be fruitful and open to life. We ended our last discussion by considering the fact that some methods of treating infertility may be perfectly acceptable and even praiseworthy, while others are seriously immoral. In this post, we will consider one such treatment: In vitro fertilization (IVF). While it has become a commonplace treatment for infertility, IVF is not compatible with the ends of marriage nor the human good as such.. So, what is IVF? In vitro fertilization is the process by which several human eggs are aspirated from a womans ovary, mingled with her partners (or someone elses) sperm, and then grown in a petri dish (in vitro is Latin for in glass). When conception takes place, the embryos are then implanted in the womans womb in the hope that at least one of ...

In Vitro Fertilization (literally, fertilization in glass) is a procedure during which the egg, instead of being fertilized in the womans fallopian tube, is fertilized in a test tube or petri dish. When minimal sperm is available, frequently ICSI - intracytoplasmic sperm injection - is performed.

Currently in the UK, women over 40 years old are allowed to have three embryos used in an IVF treatment cycle, but the research published in The Lancet says the chances of success are no greater than for two while the risk of complications is higher.. The finding is likely to result in new UK guidelines for IVF treatment recommending using no more than two embryos in any one cycle of treatment, and similar recommendations being made in other parts of the world.. A major complication of IVF treatment is multiple pregnancy - the birth of twins or triplets - due to the placement of more than one embryo during treatment.. Currently around 40 per cent of US and 21 per cent of European IVF treatment cycles have three or more embryos transferred and around 20-30 per cent of IVF births result in multiple pregnancy. However, multiple pregnancy carries risks such as higher rates of pre-eclampsia, premature birth, caesarean section and blood loss.. The UK Human Fertilisation and Embryology Authority (HFEA) ...

In vitro fertilization has resulted in an estimated 4000-5000 births in the world. The procedure has been accepted in Europe, America and Australia and several hundred IVF clinics are operating successfully. The newer procedures of GIFf, embryo freezing and donor oocyte IVF have become established and are dealt with in several chapters. GIFf has become the procedure of choice for patients with infertility of unknown origin. Oocyte freezing represents an important new technology which is being developed. The routine IVF procedure has improved slightly; variation in results can be reduced by quality control of laboratory and clinical techniques. Male factor infertility has been dealt with by IVF in mild and moderate cases, but newer techniques will be required to deal with severe problems in the male. Most countries have accepted that the straightforward IVF pro cedure is ethical. Limitations concerning the use of donor oocytes and embryo experimentation exist in some religions and countries; legal
Recurrent IVF Failure is the failure to achieve a pregnancy after several IVF efforts. Recurrent Implantation Failure (RIF) is very unsatisfying for patients and Doctors. After a failed IVF cycle, it will be important for your IVF specialist to go over your file and correlate previous test results with the details of the failed cycle.. We have had patients achieve pregnancy on their very first IVF cycle and we have seen patients achieve pregnancy on their fifth cycle! In such cases, when the problem is with egg count or quality, the treatment protocol can be modified and a more aggressive approach can be adopted to maximize ovarian response. Depending on the patients age bracket, ovarian function, and the nature of the specific problem. For a better assessment, your case will need to be analyzed with all aspects included because each patient will necessitate a different approach.. ...
As abortion opposition rallies, some activists are taking aim at in vitro fertilization, frozen embryos. CHICAGO - Rosaries in hand, a small group of abortion opponents gathered outside a medical facility to pray for the unborn.. It was a familiar ritual held at an unconventional location: a fertility clinic.. An annual Bike for Life fundraiser culminated on a recent Saturday at the Naperville Fertility Center, a site where technology and science are typically heralded for enabling life where it was once deemed impossible.. Yet the crowd out front expressed concern for the fate of frozen embryos inside - particularly those that might be discarded, cryo-preserved indefinitely or donated for research - as a result of in vitro fertilization, considered the most effective form of assisted reproductive technology.. When you do IVF, you create a life, but how many lives does it take? said John Zabinski, founder of the bicycling event, which is organized by a local council of the Knights of Columbus. ...
Objectives: Pregnancy rate in in vitro fertilization (IVF) depends on many factors, such as the characteristics of the couple and the clinicobiological parameters. Interest in alternative and complementary medicine (ACM) for IVF is discussed because of the lack of scientific evidence. Energy resonance by cutaneous stimulation (ERCS), an acupuncture-like technique, consists of skin stimulation to transmit vibratory messages. The aim of this study was to evaluate the effect of ERCS on live birth rates (LBRs) in IVF. Design: A prospective observation study was performed in the Unit of Assisted Reproductive Technologies of a University Teaching Hospital. Every woman who agreed to participate in this study and received a fresh embryo transfer (ET) after IVF or Intracytoplasmic Sperm Injection (ICSI) was included. Patients randomly underwent an ERCS session on the day of ET according to the schedule of the midwife performing this technique. The control group consisted of women undergoing ET under usual
Introduction. There are many ways that human reproduction can be controlled either for better or for worse. One of the ways of controlling human reproduction is with in vitro fertilisation (IVF), this is widely used across the country for various reasons, for example IVF can be used to help infertile couples, single women, gay couples and many others to have children. IVF is quite a long process that has become more successful and popular in recent years. The process involves the womens ovaries being stimulated with hormones such as FSH (follicles stimulating hormone) or HMG (human menopausal gonadotrophin) so as to make sure that she produces several eggs, which means that there will be more eggs available to be collected. The eggs are removed from the ovaries using a special needle. On the same day that the egg is retrieved a semen sample is collected form the man. After they have both been collected the sperm are added to the eggs and then left to incubate over night. If fertilisation occurs ...
Serge at Imago Dei has some thoughts on in vitro fertilization in a series of posts: Part 1, Part 2, and Part 3 (Unfortunately, I cant get the link to Part 3 to work, so I just gave a link to his front page. Ill update it as soon as there is a valid link.). I first thought seriously about in vitro fertilization when I was leading the Responsible Technology discussion group at MIT. At the time, I thought that while there is nothing inherently wrong with in vitro fertilization, there is something truly abhorrent in its wastefulness. Many more embryos are produced than are ever used, and this practice should be an outrage to those who believe life begins at conception. The sad truth is that the pro-life movement, while opposing the deliberate destruction of the embryos, makes little effort to address the practices that lead to it. And I cannot say that I myself have done any better, since I saw the practice as terrible, but at the time it was easier just not to think about it too much: I had more ...
Global In-Vitro Fertilization (IVF) market is expected to reach USD 27 billion by 2022, according to a new report by Grand View Research, Inc. The market is driven by the increasing incidence of infertility owing to, lifestyle changes, expansion of fertility procedures for treating male infertility such as ICSI, government initiatives to provide better reimbursement policies, and continuous efforts by the industry contributors. Moreover, the availability of genomic testing enabling the prevention of the transfer of genetic disease during IVF use is further expected to drive the market demand. The increase in the number of IVF treatment has led more insurance players to cover the IVF procedures. This has ultimately led to competitive pricing and has moderated the treatment costs as IVF has been a successfully practiced technology. This will most likely drive the market by introducing treatment standardization and automation. The behavioral shift in the society is a major factor contributing to ...

Clinical trial: Sibling Oocyte Study of Medium for In Vitro Fertilization/Intracytoplasmic Sperm Injection (IVF/ICSI) With no Human Serum Albumine
In previous years of in-vitro fertilization research, it was thought that fresh embryo transfers were superior to frozen embryo transfers and that frozen embryo transfers should be avoided and only used when there was no other option. New research in recent years however has changed the data on fresh and frozen embryo transfer cycles and the effectiveness of each in terms of pregnancy and live birth rates. This has in turn impacted many providers decisions to perform a freeze-all delayed embryo transfer versus a fresh embryo transfer.. Many people may become confused about the terminology regarding frozen embryo transfers. A freeze-all approach is where all embryos from the resulting IVF cycle are cryopreserved (frozen) and a fresh embryo transfer is not attempted until a later date. This is different from freezing extra or leftover embryos which are the result following a fresh IVF transfer.. The three main things that affect the pregnancy and live birth rate following IVF treatment are ...
Polycystic Ovary Syndrome is the most common endocrine disorder in women, is estimated to affect more than 5% of the population and is associated with chronically elevated serum androgen concentrations.Evidence suggests that polycystic ovary syndrome has a negative impact on pregnancy outcomes, with an increased risk of gestational diabetes, hypertensive disease during pregnancy,and preterm birth,which is partially related with the hyperandrogenic environment.Diane-35 has been proved to be the most effective anti-androgenic drug.At present, there is no direct evidence that Diane-35 has a positive effect on the clinical outcome of polycystic ovary syndrome patients undergoing In-vitro fertilization/Intracytoplasmic sperm injection ...

OBJECTIVE: To compare the obstetric outcome of in vitro fertilization pregnancies with normally conceived pregnancies. STUDY DESIGN: The obstetric outcome of in vitro fertilization pregnancies achieved in 763 British residents at two in vitro fertilization clinics resulting in the births of 961 babies were compared by means of the relative risk statistic with a control group of naturally conceived primiparous pregnancies matched by maternal age and multiplicity of pregnancy. RESULTS: Twenty-five percent of in vitro fertilization pregnancies were multiple pregnancies. The incidence of singleton term breech presentation was similar to that among controls. As compared with controls there was an increased incidence among in vitro fertilization pregnancies of vaginal bleeding and hypertension requiring hospitalization (p less than 0.001) and cesarean births (p less than 0.001) and, among in vitro fertilization singleton pregnancies, an increased incidence of intrauterine growth retardation (p less than 0.05)

Effect of levothyroxine treatment on in vitro fertilization and pregnancy outcome in infertile women with subclinical hypothyroidism undergoing in vitro fertilization/intracytoplasmic sperm injection.
Children born after intracytoplasmic sperm injection (ICSI) are at increased risk of specific major birth defects compared with children born after in vitro fertilization (IVF). However, whether this risk is due to the treatment itself (i.e., IVF or ICSI) or underlying male subfertility is unknown. This study investigated the associations between male subfertility and the risk of major birth defects in children born after IVF and ICSI. We conducted a retrospective cohort study using data from the Japanese assisted reproductive technology registry between 2007 and 2014. Fresh embryo transfer cycles registered from 2007 to 2014 that resulted in singleton live births, still births, or selective terminations were included (n = 59,971). Major birth defects were defined by the US Centers for Disease Control and Prevention guidelines, excluding chromosomal abnormalities. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using generalized estimating equations adjusting for potential
INTRODUCTION: Mild ovarian stimulation has been conceived, proposed and implemented in clinical practice as a safer and cheaper alternative to conventional strategies of controlled ovarian hyperstimulation in preparation for in vitro fertilization (IVF). Our aim was to summarize the key evidence on this topic and explore its possible role as the standard treatment option for women undergoing IVF. MATERIALS AND METHODS: A short narrative review of the existing literature, with emphasis on mild ovarian stimulation clinical and cost effectiveness, as well as treatment limitations. RESULTS: Numerous studies highlight mild ovarian stimulations favorable characteristics with respect to oocyte/embryo quality, reduced patient risk, and ease of intervention. There is, however, a need for high-quality laboratory environment. Limitations regarding poor responders, older women, or those seeking ovarian stimulation for non-infertility indications should also be considered. Finally, outcomes on the cumulative
To investigate the impact of follicular flushing on the number of oocytes retrieved and embryo quality and to determine the optimal number of flushings for poor ovarian responders (PORs) undergoing in vitro fertilization (IVF). This retrospective study included 291 IVF cycles in 224 patients who were PORs and had no more than three dominant follicles on retrieval day. During oocyte retrieval, follicular fluid was aspirated and examined for an oocyte. If no oocyte was identified, follicular flushing was repeated until an oocyte was retrieved or up to a maximum of nine times. The mean number of oocytes retrieved by aspiration and subsequent flushes was significantly higher than the number retrieved from the initial aspirate (1.73 ± 0.96 VS. 1.23 ± 1.00, P = 0.000). The total recovery rate was 83.7% (503/601), which was significantly higher than the 59.6% recovery rate for direct aspiration (P = 0.000). Before the 4th follicular flushing, the cumulative recovery rate increased significantly as flushing

Placing embryos in the optimal location within the uterus is a key factor determining the success of in-vitro fertilization. The studys lead author, Robert Gergely, M.D., has identified a new embryo placement target as the point where the fallopian tubes would intersect if they were extended beyond their natural length.. This imaginary intersection, which has been dubbed the Maximal Implantation Potential (MIP) Point, is where embryos typically implant and develop in natural pregnancies. Precision in embryo placement has become especially critical in recent years given the trend to limit the number of embryos transferred during in-vitro fertilization to just a single embryo in order to reduce the likelihood of multiple births.. The study, titled Maximal Implantation Potential (MIP) Point - Suggested Target for Optimal Embryo Placement Within the Uterine Cavity During Embryo Transfer (ASRM: P-665), was led by Dr. Gergely, who serves as medical director of the 3D Sonography Center of Beverly ...
Indeed, the focused work of these authors (and others) over the past decade is helping to end a subculture of debulking advanced-stage endometriosis that has vexed our fertility patients for a generation. If the pendulum is finally swinging towards a minimalist approach to severe endometriosis in infertility patients we owe it - aside from the great progress of ART - to the accumulation of evidence such as this. Your latest work also gives us the chance to remind to all of us in the field that indications for excision of endometriomas in infertility patients still exist (aside from patients with pain, obviously) and should remain very clear in our mind. I am referring in particular to two relatively common clinical scenarios: 1) radiologic diagnosis of endometriomas over 4 cm in diameter without prior pathologic diagnosis, and 2) endometriomas as the sole identifiable infertility factor. Surgery in the former will avoid the rare but unforgivable occurrence of missing a patient with ovarian ...
In vitro fertilisation (IVF) is the last technique used because it is more complicated and expensive. In vitro fertilisation will be suggested when other reproductive methods have failed or are impossible.. Some male or female conditions prevent fertilisation other than with IVF. This might be women who dont ovulate or whose fallopian tubes are completely blocked or who have moderate or severe endometriosis, which makes fertilisation or implantation impossible. ou encore qui souffrent dendométriose modérée ou sévère qui rend souvent impossible la fécondation ou limplantation.. On the male side, there are also severe sperm production issues (absent or very low quantities). The mans ejaculatory duct may be obstructed, which prevents the sperm from being ejected. Each couple has a story, and each one will have a road they need to take when trying to procreate. Du côté masculin, il y a aussi les troubles sévères dans la production de spermatozoïdes,.

Introduction. Low ovarian response to stimulation protocol in intracytoplasmic sperm injection (ICSI) is frustrating to physicians and patients especially when the initial evaluation seems to be fair. Regarding this emerging problem, different measures usually taken trying to rescue the cycle and avoid cancelation. It was estimated that about 9-18% of cycles result in this low response with small number of follicles and low estradiol level.1. The term poor responder has been used to determine women who require large doses of stimulation medications and who make less than an optimal number of eggs. The definition of low responders differs from center to other, but the most used one is that less than four dominant follicles on day of human chorionic gonadotropin (hCG) administration.2. The occurrence of low response to ovarian stimulation is usually suspected in old age, although it could occur at any age. Ovarian reserve is the main factor affecting response to stimulation, it could be assessed ...
In the majority of cases when a fertility treatment cycle fails or when someone suffers a miscarriage the cause is embryo-related.

The incidence of ICSI cycles containing at least one fragmented oocyte was 3.3% (93/2,844). Twelve patients were represented more than once in these 93 index cycles. Only the first cycles (n = 81) were included, of which 28 contained fragmented oocytes at cumulus stripping, 48 at fertilization check, and five at both. Compared with matched controls, index cycles had fewer good-quality embryos available for transfer (18.8% vs. 32.1%) and significantly lower rates of implantation (20.3% vs. 32.7%), clinical pregnancy (33.3% vs. 58.0%), and ongoing delivery (29.6% vs. 49.4%). The cumulative ongoing delivered rate was also significantly lower for index cycles (32.1% vs. 55.6%), with no difference in the percentage of cycles with cryopreserved embryos remaining at study conclusion (13.5% vs. 23.5%).. Conclusion(s): ...

Purpose: To investigate impact of the one‐carbon metabolism (OCM) on oocyte maturity and embryo development. Methods: This prospective study analyzed 18 women who agreed to participate. We measured the OCM biomarkers concentrations including Vitamin B12 (VB12), folic acid (FA), and homocysteine (Hcy) in serum and follicular fluid (FF), and assessed their correlation. We also evaluated the influence of such OCM biomarker concentrations in mono‐FF on oocyte maturation, fertilization, embryo quality, and consequent pregnancy after embryo transfers. Results: All biomarkers showed a high concentration variability in different follicles of each woman, but their mean levels correlated with the serum levels. Among the 106 collected oocytes, 92 were mature, 59 were fertilized, and 16 yielded good‐quality embryos. We performed 26 single embryo transfers, and 7 patients achieved clinical pregnancies. VB12 concentration (FF) was significantly lower in fertilized than unfertilized oocytes by univariate
Utrogestan at 100 mg/d is as effective as Utrogestan at 200 mg/d in reducing premature luteinizing hormone surge during controlled ovarian hyperstimulation in normally ovulating women undergoing in vitro fertilization or intracytoplasmic sperm injection treatments in combination with embryo cryopreservation.
In Vitro Fertilization (IVF) is a method of assisted reproduction in which the mans sperm and the womans egg are combined in a laboratory. Following fertilization and early embryo development in the laboratory, an appropriate number of embryos are transferred to the womans uterus.. Natural conception begins with the release of a single ovum (egg) from the womans ovaries. The fallopian tube picks up the egg, and it is within the fallopian tube that the sperm will fertilize the egg. Following fertilization, the zygote, or early embryo, stays in the tube for about three days while it divides into more and more cells. The embryo is then transported to the uterus where it will float for approximately three days until it implants into the wall of the uterus.. IVF was originally designed for couples in which the womans fallopian tubes were absent or damaged. The events normally occurring in the fallopian tubes, including fertilization and early embryo development, occur in the laboratory ...

A poster presentation showed that omega-3 fatty acids are beneficial in improving the fertilization rate in IVF cycles.. 98 couples with unexplained fertilization failure were randomized to 1,000 mg omega-3s versus no treatment. The fertilization rate was higher (76.5% versus 50.4,%), there were more good quality embryos, and the implantation rate was increased.

Background: Delayed pregnancy in women and marked increase in the numbers of older women who fail to respond to ovarian stimulation had been a significant issue. This study aims to assess the value of basal serum testosterone level as a predictor of ovarian response for induction of ovulation in women with unexplained infertility undergoing IVF (in vitro fertilization) cycle. Patients and Methods: A prospective study was conducted in Ain Shams University Maternity hospital Infertility Center during a period of time from October 2016 to June 2017. This study recruited 89 women. On day 2 or 3 of a spontaneous menstrual cycle of the included women within 3 months before fresh IVF cycle, basal hormonal (FSH, LH, estradiol, total testosterone) concentrations, AFC (antral follicle count) were performed. Using the Long-protocol for induction of ovulation, serial monitoring of ovarian response was assessed by transvaginal ultrasound. When the expected ovarian response was reached (at least three oocytes ≥ 17

Mitochondria are the most abundant organelles within the oocyte and are fundamental for energy metabolism, spindle formation and chromosome segregation. Therefore it is likely that a reduction in mitochondria number or function may explain the decreased quality, developmental potential and increased frequency of chromosomal non-disjunction in oocytes from older women, especially when coupled with IVF stimulation regimens. The aim of this study was to delineate, using a novel bovine model of human IVF stimulation, the effects of ovarian stimulation regimens and maternal age on mitochondrial DNA copy number and function of the cumulus-oocyte-complex. Seven young (4 years old) and five old (11 years old) cloned cows with an identical genetic background, and managed as one herd, were subjected to repeated rounds of ovarian stimulation; four natural (hCG), three mild (FSH and hCG) and two heavy stimulated (GnRH agonist, FSH and hCG) cycles. Individual cumulus-oocyte-complexes were collected. The ...
