Preconception zinc deficiency could spell bad news for fertility
The availability of micronutrients in the ovarian environment and their influence on the development, viability and quality of egg cells is the focus of a growing area of research. A new study shows that zinc deficiency can negatively affect the early stages of egg development, reducing the ability of the egg cells to divide and be fertilized. This may affect fertility months in the future. Researchers will present their results at the American Physiological Society annual meeting at Experimental Biology 2018 in San Diego. (2018-04-24)

No sex without kiss! Researchers discover how the brain controls sex
Kisspeptin has already been identified as the key molecule within the brain responsible for triggering puberty and controlling fertility. A new study reveals that a subset of neurons in an evolutionarily ancient part of brain, the hypothalamus, drive both attraction to the opposite sex and sexual behavior by two independent mechanisms.

Both fresh and frozen embryos offer similar chances of baby after IVF
Researchers have found that in women who have infertility but ovulate normally, using fresh or frozen embryos for in vitro fertilization result in similar rates of live births. (2018-01-10)

Estrogen discovery could shed new light on fertility problems
Estrogen produced in the brain is necessary for ovulation in monkeys, according to researchers at the University of Wisconsin-Madison who have upended the traditional understanding of the hormonal cascade that leads to release of an egg from the ovaries. Their findings may reveal the cause of some undiagnosed infertility problems and point the way to new methods of birth control. (2017-12-12)

Vitamin D may be key for pregnant women with polycystic ovary syndrome
Vitamin D may play a key role in helping some women seeking treatment for polycystic ovary syndrome (PCOS)-related infertility get pregnant. PCOS is a hormonal disorder affecting 5 to 10 percent of women of reproductive age. Results of the study show women who were Vitamin D deficient when starting fertility treatments were 40 percent less likely to achieve a pregnancy. (2017-11-03)

50 years ago, Clomid gave birth to the era of assisted reproduction
In the journal Fertility and Sterility, Dr. Eli Adashi writes a history and appreciation of the wonder drug Clomid, which radically changed what doctors could do for couples struggling to have children. (2017-09-13)

Long-term sexual intimidation may be widespread in primate societies
After observing the mating habits of chacma baboons living in the wild over a four-year period, researchers have found that males of the species often use long-term sexual intimidation to control their mates. The findings reported in Current Biology on July 6 suggest that this mating strategy has a long history in primates, including humans, and may be widespread across social mammals -- especially when males of a species are typically larger than females.

Mixed results on effectiveness of acupuncture to treat stress urinary incontinence, infertility
Electroacupuncture improved stress urinary incontinence -- that's when a woman can experience an involuntary loss of urine such as when sneezing or coughing -- but acupuncture did not increase the likelihood of childbirth among women with infertility, according to two studies published by JAMA. (2017-06-27)

Acupuncture may not be effective in treating infertility
Acupuncture, alone or with the medication clomiphene, does not appear to be effective in treating infertility in women with polycystic ovary syndrome (PCOS), according to an international team of researchers. The finding casts doubts on previous smaller trials that have suggested that acupuncture may improve reproductive function in women affected by infertility. (2017-06-27)

Monash discovery may help unlock the key to infertility in older women
Findings from new research led by the Monash Biomedicine Discovery Institute (BDI) and University College London may finally resolve, and potentially provide answers, as to why older women have higher incidences of miscarriage and have babies with chromosomal abnormalities. (2017-05-18)

Children conceived after fertility treatments are at increased risk for pediatric cancers
'The research concludes that the association between IVF and total pediatric neoplasms and malignancies is significant,' Prof. Sheiner says. 'With increasing numbers of offspring conceived after fertility treatments, it is important to follow up on their health.' (2017-04-25)

Dietary supplement may enhance dairy cattle health and reproductive capacity
Dairy cattle diets are often deficient in the essential amino acid methionine; supplements have been shown to increase milk production and protein concentration. A new study shows that rumen-protected methionine supplements can change gene expression in the ovarian follicle, potentially leading to shorter time between ovulation events. Methionine supplements also decrease expression of genes related to inflammation in the cells of the ovarian follicle. (2017-04-17)

Treating polycystic ovary syndrome early may help prevent later drop in fertility
In adolescent girls with polycystic ovary syndrome (PCOS), bringing the amount of abdominal visceral fat and liver fat down to normal restores ovulation, normalizes the symptoms of androgen excess, and may help prevent future subfertility, new research from Spain suggests. The results of the study will be presented Tuesday, April 4, at ENDO 2017, the annual meeting of the Endocrine Society, in Orlando. (2017-04-04)

Male hormone plays key role in ovarian development

Contraception influences sexual desire in committed relationships
How often women in heterosexual couples desire sex depends on how committed the relationship is and what type of birth control the woman uses. (2016-12-08)

How human eggs end up with the wrong number of chromosomes
One day before ovulation, human oocytes begin to divide into what will become mature eggs. Ideally, eggs are packaged with a complete set of 23 chromosomes, but the process is prone to error, especially with age. In a Review in Trends in Cell Biology, researchers discuss the latest research on why many human oocytes frequently have a wrong number of chromosomes -- which may lead to genetic disorders, such as Down syndrome and miscarriage. (2016-10-20)

Could assisted reproduction reduce birth defects for older women?
Babies born to women aged 40 and over from assisted reproduction have fewer birth defects compared with those from women who conceive naturally at the same age, according to new research from the University of Adelaide. (2016-10-17)

Strenuous exercise is unlikely to prolong labor or boost risk of premature birth

A molecular alarm clock awakens resting ovules
How does each resting ovule know that it is time to prepare for ovulation? In a study published in the latest issue of Nature Communications, researchers at Instituto Gulbenkian de Ciencia, at University of Algarve, and at University at Albany discovered in the fruit fly a molecular 'alarm clock' that tells resting ovules when is the right time to wake up. Defects in this alarm clock result in female fertility problems. (2016-08-17)

Yale researchers shed light on evolutionary mystery: Origins of the female orgasm
Female orgasm seems to be a happy afterthought of our evolutionary past when it helped stimulate ovulation, a new study of mammals shows. (2016-08-01)

Female bonobos send mixed messages to males
Sexual swellings are unreliable signals of fertility in female bonobos. (2016-07-06)

Deceptive sexual signals keep the peace in a bonobo society
Female bonobos could have become the dominant sex in their societies by deceiving males as to when they are likely to conceive, according to research published in the open-access journal BMC Evolutionary Biology. The females' unreliable sexual swellings, which can remain swollen up to 31 days, make it difficult for a male to monopolize and guard female mates to ensure he sires their offspring. This may reduce aggressive mate competition and male sexual coercion toward females, and result in bonobo societies being relatively peaceful. (2016-06-29)

Are drops in estrogen levels more rapid in women with migraine?
Researchers have long known that sex hormones such as estrogen play a role in migraine. But there's been little research on how that works. Do women with migraine have higher estrogen levels in general? Higher levels at the peak of the monthly cycle? (2016-06-01)

Female smokers more likely to kick the habit by 'timing' their quit date with their menstrual cycle
Women who want to quit smoking may have better success by carefully timing their quit date with optimal days within their menstrual cycle, according to a new study from researchers at the Perelman School of Medicine at the University of Pennsylvania. The results, published online this month in Biology of Sex Differences, were also presented at the annual meeting of the Organization for the Study of Sex Differences, held at Penn. (2016-05-31)

Fish courtship pheromone uses the brain's smell pathway
Research at the RIKEN Brain Science Institute in Japan has revealed that a molecule involved in fish reproduction activates the brain via the nose. The pheromone is released by female zebrafish and sensed by smell receptors in the noses of the males. The neural pathway and brain areas involved in transforming this molecular messenger into courtship behavior in fish were also identified and reported in Nature Neuroscience on May 30. (2016-05-30)

IVF, often cited for high twin birth rate, could reduce it
The US has reached a record-high rate of twin births, and the use of in vitro fertilization is part of the reason. But in a commentary in this month's American Journal of Obstetrics & Gynecology, Dr. Eli Adashi argues that implemented differently, IVF could instead reduce the rate toward natural levels. (2016-03-04)

Female fertility is dependent on functional expression of the E3 ubiquitin ligase Itch
Protein ubiquitination is known to result in its proteasomal degradation or to serve as a signal for tissue-specific cellular functions. Here it is reported that mice with a mutant form of the E3 ubiquitin ligase ITCH display reduced litter sizes due to a maternal effect. Mutant females had decreased numbers of implantations, corpa lutea, and extended estrous cycles. The results indicate for the first time that loss of functional ITCH disrupts female reproduction. (2016-02-29)

Infertility treatments do not appear to contribute to developmental delays in children
Children conceived via infertility treatments are no more likely to have a developmental delay than children conceived without such treatments, according to a study by researchers at the National Institutes of Health, the New York State Department of Health and other institutions. The findings, published online in JAMA Pediatrics, may help to allay longstanding concerns that conception after infertility treatment could affect the embryo at a sensitive stage and result in lifelong disability. (2016-01-04)

Postpartum family planning services should be a top reproductive health priority
Despite their importance for both healthy pregnancies and the well-being of existing children, postpartum and post-abortion family planning have received insufficient attention and resources in recent years. An analysis of data from 35 family planning interventions in low- and middle-income countries provides useful guidance for strategies to promote postpartum family planning, in ways that take different contexts into account. (2015-12-11)

Researchers use ovarian follicles to preserve fertility
Researchers at the University of Michigan have identified a potential new approach to fertility preservation for young cancer patients that addresses concerns about beginning cancer treatment immediately and the possibility of reintroducing cancer cells during the fertility preservation process.
