Embryonic loss of potential lambs resulting in partial failure of multiple ovulations is a significant factor in the reproductive rate of prolific breeds. The roles of genetic and nutritional variation (and their possible interaction) on embryonic loss were studied by mating blackface and whiteface ewes of either high or low body condition to either Suffolk or Polypay rams. Variation in body condition was created by placing ewes on either high or low planes of nutrition for 13 weeks prior to breeding and the first 30 days of pregnancy with the goal of achieving mean body condition scores of 4.0 and 2.5, respectively. Low ewes were flushed to overcome expected depression in ovulation rate due to poor body condition. The actual difference achieved was 1.0 condition score units (and 11 kg) at the commencement of mating. Embryo loss was defined as difference between ovulation rate as measured by laparoscopy shortly post-mating, and litter size at term. Mean ovulation rate for ewes conceiving to ...

Ovulatory activity. During the course of the 12 month experimental period, and according to serum progesterone profiles, a clear seasonal pattern of ovulatory activity became apparent in the 3 genotypes evaluated (Fig. 3). 45.8 % of the goats experienced at least one short- increase in serum progesterone concentrations (≥1.0 ng/ml of progesterone in only one sample) before the first recorded ovulation. The percentage of does experiencing these short- increases in progesterone was greater (P =0.07) in the Criollo x Nubian (75 %) as compared to the Nubian (25 %) genotype. No differences in this response were found when considering the other genotype comparisons (Nubian vs. Alpine and Nubian vs. Criollo x Nubian). Once initiating cyclic ovulatory activity and before its end, 7 does (29.1%) presented other short-increases in serum progesterone (1, 2 and 4 does in the Nubian, Alpine and Criollo x Nubian genotype, respectively; P ,0.10).. Two does (one in the Alpine and one in the Criollo x Nubian ...
Initially egg freezing was used for medical reasons where women suffering from diseases like cancer used to freeze their eggs before going in for chemotherapy, which affects the ovulation process. However, this technique is now being used for lifestyle reasons too. Women in their mid- to late-twenties are taking recourse to the method that lets them focus on their careers, without having to bother about the perils of a late conception. Or, worry about turning infertile by the time they are ready for pregnancy. Those afflicted with a disease that could lead to infertility are opting for it as well. Since the motherhood age coincides with the time when their careers are taking off, women face a dilemma. They are often scared of late conception and force themselves into motherhood even if they are not ready for it. Many women presently face Polycystic ovarian syndrome which may hamper the quality of the egg. To avoid complications in future, they opt for egg freezing. Now, with egg banking, many ...

Dieters are shunning carbohydrates, but scientists are hungry for information about these molecules. They help the immune system discriminate friend from foe, are an ingredient in the goo that surrounds and supports cells, and may play a role in aging and diseases such as cancer.. The Japanese site Glycoforum, sponsored by the Seikagaku Corp. and the Mizutani Foundation for Glycoscience, is a gathering place for researchers with a taste for carbohydrate biology. Four main sections post short articles, written by academic experts in Japan and other countries, on topics from the evolution of the sugars in milk to the importance of carbohydrate-adorned receptors for flu susceptibility. One focus of the site is hyaluronan, a molecule prevalent in the gel around cells. You can learn about its effects on ovulation and development and read about how the cells carbohydrate milieu can encourage the spread of cancer. Malignant cells exude more hyaluronan, which in turn alters the cells internal skeleton ...
Many signaling pathways that contribute to tumorigenesis are also functional in pregnancy, although they are dysregulated in the former and tightly regulated in the latter. Transformation-related protein 53 (Trp53), which encodes p53, is a tumor suppressor gene whose mutation is strongly associated with cancer. However, its role in normal physiological processes, including female reproduction, is poorly understood. Mice that have a constitutive deletion of Trp53 exhibit widespread development of carcinogenesis at early reproductive ages, compromised spermatogenesis, and fetal exencephaly, rendering them less amenable to studying the role of p53 in reproduction. To overcome this obstacle, we generated mice that harbor a conditional deletion of uterine Trp53 and examined pregnancy outcome in females with this genotype. These mice had normal ovulation, fertilization, and implantation; however, postimplantation uterine decidual cells showed terminal differentiation and senescence-associated growth ...

Can I get pregnant the first day of my period - Can I get pregnant on the first day of my period if my partner ejaculates inside of me? Could be ovulation. If it is the true first day of your period coming two weeks after ovulation when the uterine lining is shedding, it would not be possible to conceive. However, sometimes bleeding can occur at ovulation, and if a woman interprets this as the first day of her period it would be the exact wrong time to have unprotected sex!
RIVERA LOZANO, María Teresa et al. Seasonal variation in ovulatory activity of nubian, alpine and nubian X criollo does under tropical photoperiod (22° N). Trop. subtrop. agroecosyt [online]. 2011, vol.14, n.3, pp.973-980. ISSN 1870-0462.. In the present study, seasonal variation in ovulatory activity of Nubian, Alpine and Criollo x Nubian goats in the semiarid region of central-northern Mexico (22° 14 N) was examined. The study was conducted under natural photoperiod and climate conditions during a whole year. Eight female goats per breed were grouped separately and exposed to visual, olfactory and audible signals of bucks. Blood samples were obtained twice per week and serum progesterone concentrations were determined. All goats presented a clear pattern of seasonal ovulatory activity based on serum progesterone profiles. Length of the ovulatory activity period did not differ between genotypes (P ,0.10), and had an average duration of 4.3 months. Nevertheless Criollo x Nubian goats ...
Definition of multiple ovulation in the Legal Dictionary - by Free online English dictionary and encyclopedia. What is multiple ovulation? Meaning of multiple ovulation as a legal term. What does multiple ovulation mean in law?
Q. So how do you prove that the pill acts as an abortifacient?. A. The answer to this question can be found by comparing the rate of break-through ovulation and the detected pregnancy rate. The ovulation rate has been reported to be about 27 ovulations in 100 women using the pill for one year. But the detected pregnancy rate is much lower at around 4 pregnancies per 100 women using the pill for one year.. As you can see, there is a big difference between the number of women who ovulation (27) and the number of detected pregnancies (4). What has happened within the woman s body to reduce the high ovulation rate to such a low number of detected pregnancies? I suggest that one answer to this important question is that pregnancies have begun, because ovulation and fertilization have occurred, but some of these pregnancies are terminated because implantation cannot take place. The pill has damaged the lining of the womb, stopping implanation.. Q. You talk about the pill causing damage to the lining ...
These studies were undertaken to establish whether there are gene-specific differences in FSH and LH concentrations in the plasma of ovariectomized ewes that are crosses between local breeds (German Mutton Merino, Texel or Suffolk) and carriers and non-carriers of Booroola (FecB) or Cambridge (FecC) genes for prolificacy. The relationships of FSH or LH levels to ovulation rates, predetermined over two oestrus cycles before ovariectomy, were also determined. Ewes that were carriers (F+) or non-carriers (F++) of Booroola or Cambridge genes included in the studies were: Booroola x German Merino (BM), Booroola x Texel (BT), Cambridge x Cambridge (CC), Cambridge x Suffolk (CS) and Cambridge x Texel (CT). Ovulation rates were significantly higher in the F+ genotypes than in the F++ genotypes. Basal and LHRH-induced FSH and LH secretion in ovariectomized ewes were measured in plasma of blood collected by venipuncture. The effects of oestradiol-17beta (E2) or progesterone (P4) implants for 8 days, ...
Eleven generations of selection for increased index of ovulation rate and embryonal survival rate, followed by three generations of selection for litter size, were practiced. Laparotomy was used to count corpora lutea and fetuses at 50 d of gestation. High-indexing gilts, approximately 30%, were farrowed. Sons of dams in the upper 10% of the distribution were selected. Selection from Generations 12 to 14 was for increased number of fully formed pigs; replacements were from the largest 25% of the litters. A randomly selected control line was maintained. Responses at Generation 11 were approximately 7.4 ova and 3.8 fetuses at 50 d of gestation (P | .01) and 2.3 fully formed pigs (P | .01) and 1.1 live pigs at birth (P | .05). Responses at Generation 14 were three fully formed pigs (P | .01) and 1.4 live pigs (P | .05) per litter. Number of pigs weaned declined (P | .05) in the index line. Total litter weight weaned did not change significantly. Ovulation rate and number of fetuses had positive genetic
During the follicular phase of the primate menstrual cycle, a single follicle usually matures to the preovulatory stage and releases its oocyte for fertilization and the potential establishment of pregnancy. In assisted reproductive technology procedures, it is desirable to override the natural process of follicle selection to produce many oocytes that are capable of being fertilized and undergoing normal embryo development. The goal of this chapter is to summarize the current views regarding the natural process of follicle selection in primates and to discuss how this process may be amplified to produce a greater number of oocytes.
Antioxidants neutralize these potentially harmful substances (free radicals) and may improve health and slow down the aging process.. The Effect of Antioxidants on Ovulation and Female Fertility. But when Dekel and her research team including her former and present Ph.D. students Dr. Ketty Shkolnik and Ari Tadmor applied antioxidants to the ovaries of female mice, the results were surprising: ovulation levels dropped precipitously. That is, very few eggs were released from the ovarian follicles to reach the site of fertilization, compared to those in untreated ovaries.. To understand what lies behind these initial findings, the team asked whether it is possible that the process of ovulation might rely on the very harmful substances destroyed by antioxidants - reactive oxygen species.. Further testing in mice showed that this is, indeed, the case. Antioxidants may be connected to infertility in women because they interfere with the ovulation process.. This fertility research results help fill ...
SO WHAT IS IUI?. So if youre wondering what IUI is about, IUI stands for intrauterine insemination. It is one of the types of infertility treatment available. Another known type of treatment is IVF.. Normally, every month, a womans ovary releases an egg which travels down the fallopian tubes for the possibility of being fertilized by a male sperm. In the case that conception does not occur, the egg and the uterine lining get shed which is what we see as our menstrual period. The process of which the ovary develops the follicle that matures to release the egg is called ovulation. This process is controlled by hormones such as luteinizing hormone and follicle stimulating hormone.. In IUI, a womans ovaries are stimulated to produce multiple eggs through the use of hormones to increase the chances of conception. Hormones can be given orally or given through injection. Through blood work and ultrasounds, your ovulation process will be externally monitored and controlled to optimize your chances of ...

Yesterday I met with my gynecologist. Despite an insanely long wait my actual appointment was brief. I described my symptoms and he did an exam. He ordered blood work and told me he wanted me to have a sono done. Then he said I should schedule an appointment and well "figure things out." When I described what had happened with the ovulation tests he said I was likely having overlapping cycles. A LH surge doesnt necessarily mean ovulation. I interpret this as Im likely making cysts ...
Mitt Romney ripped into Donald Trump on Wednesday afternoon, claiming that Trump is unfit for the presidency if he doesnt release his tax returns. Romney took to Facebook to share his message, saying "it is disqualifying for a modern-day presidential nominee to refuse to release tax returns to the voters, especially one who has not been subject to public scrutiny in either military or public service.". Romneys attack comes a day after Trump swatted aside suggestions that he should release his tax returns before the election. "Theres nothing to learn from them," Trump told the Associated Press on Tuesday.. Romney disagreed and played the role of armchair psychologist, speculating about Trumps true motivations for refusing to make his records public. "There is only one logical explanation for Mr. Trumps refusal to release his returns: there is a bombshell in them," Romney wrote. "Given Mr. Trumps equanimity with other flaws in his history, we can only assume its a bombshell of unusual ...
The answer to the question is: No, the Romney employees in the Michigan office did not "blow it" by showing Stacy the door. To begin with, Staacy is an unofficial Santorum campaign operative-he even solicits donations for the candidate. He puts a pro-Santorum and an anti-Romney spin on his coverage, and he is a fervent member of the anybody-but-Romney brigade. He showed up unannounced, after hours, wanting to "take a picture" of the office. What the hell? No sane employee of any non-Santorum campaign would have let Stacy barge in and roam around their office.. And then, after getting just the reaction he should have expected, Stacy blogs a round-up of hit pieces on Romney, including a cheap shot that misconstrues and mocks Romneys religious devotion. Which, of course, only confirmed that the Romney folks did the right thing by blocking Stacy from doing whatever it was he planned to do at the Romney office.. Dick move, Stacy. Dick move.. ...
I was doing a search for abnormal bleeding and came acrost this site.I am in my late 30s, 2 kids and always had normal 29 day periods lasting four or five days (two of heavy bleding).But this month, I started bleeding again (pink-red at first, then brown after awhile) about a week after my period stopped.This continued for four days.Then it stopped and I had signs of ovulation.It stopped for four-five days while I was ov.I did research online and managed to convince myself this was normal ovulation bleeding, in spite the fact that id never had it before.But now, after five days of no bleeding, the bleeding/spotting has returned.I have a gyn appointment early next week.I am very afraid of cancer, even though i know theres not a high chance of that.I havent been as good about getting PAPs as I should be, but my last was about two years ago and was normal.

Romney and Santorum each finished with 25 percent of the vote, and Paul won 21 percent. But these numbers dont get at the underlying dynamics. One thing you can often count on from the Iowa presidential caucuses: the unexpected. Tuesday nights vote was no exception, at least if you subscribe to the conventional wisdom proffered by corporate media and political experts, when former Massachusetts Gov. Mitt Romney, the presumptive nominee, finished locked in a near three-way tie with two candidates deemed marginal by political wags: Rep. Ron Paul and former U.S. Sen. Rick Santorum.
