Endocrine disruptors alter female reproduction throughout multiple generations
Endocrine disruptors, hormone-altering chemicals that are widespread in our environment, can shape the brain through four generations, altering offspring's maternal behavior, sexual development and reproduction, according to a new animal study. The results of this study will be presented Monday at the Endocrine Society's annual meeting in New Orleans, La. (2019-03-25)

Brain's reward circuit activity ebbs and flows with a woman's hormonal cycle
Fluctuations in sex hormone levels during women's menstrual cycles affect the responsiveness of their brains' reward circuitry, an imaging study has revealed. While women were winning rewards, their circuitry was more active if they were in a menstrual phase preceding ovulation and dominated by estrogen, compared to a phase when estrogen and progesterone are present. These first pictures of sex hormones influencing reward-evoked brain activity in humans may provide insights into mood and anxiety disorders. (2007-02-02)

Prostate cancer drug slows memory loss in women with Alzheimer's disease
Women with Alzheimer's disease showed stable cognition for a year when a drug that is more commonly used to treat advanced prostate cancer was added to their drug regimen, according to a new study from researchers at the University of Wisconsin-Madison. (2015-01-20)

Respiratory symptoms vary according to stage of menstrual cycle
Respiratory symptoms vary significantly during different stages of the menstrual cycle, with higher frequencies during the mid-luteal to mid-follicular stages, according to a new study. (2012-11-09)

Women, quitting smoking for New Years? Time it with your period
'Our data reveal that incontrollable urges to smoke are stronger at the beginning of the follicular phase that begins after menstruation. Hormonal decreases of oestrogen and progesterone possibly deepen the withdrawal syndrome and increase activity of neural circuits associated with craving,' Adrianna Mendrek says. She believes that it could therefore be easier for women to overcome abstinence-related withdrawal symptoms during the mid-luteal phrase, i.e., after ovulation. (2015-01-04)

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)

Standard treatment more effective than diabetes drug for achieving pregnancy in fertility disorder
Metformin, a drug used to treat diabetes and thought to hold great promise at overcoming the infertility associated with polycystic ovary syndrome (PCOS), is less useful for helping women with the condition achieve pregnancy than is the standard treatment with the infertility drug clomiphene, report researchers in an NIH research network. (2007-02-07)

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. (2017-07-06)

Scientists prove bird ovary tissue can be preserved in fossils
A research team led by Dr. Alida Bailleul from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences has proved that remnants of bird ovaries can be preserved in the fossil record. (2020-07-28)

How an egg cell's "operating manual" sets the stage for fertility
Recently published work from Carnegie's Allan Spradling and Wanbao Niu revealed in unprecedented detail the genetic instructions immature egg cells go through step by step as they mature into functionality. Their findings improve our understanding of how ovaries maintain a female's fertility. (2020-10-08)

Female mice are able to smell male pheromones only when ready to mate
An American study in mice reveals that hormones that dictate a female's attraction towards males do so in part by controlling her sense of smell. The findings, published June 4 in Cell, provide an example of how hormones may use the nose to circumvent the brain and influence behavior. (2015-06-04)

Birth after cancer treatment with removal and storage of ovary
For the first time in Germany, a woman has given birth to a child after removal and preservation of tissue from one of her ovaries. This course of action was necessary to avoid infertility owing to chemo- and radiotherapy. Andreas Mueller and his colleagues report the case in the current issue of Deutsches Aerzteblatt International. (2012-01-26)

What women really want
Earlier research purported to show links between a woman's cycle and how attracted she was to men's behavior. Research at the University of Göttingen questions this. It showed shifts in women's cycles did not affect their preferences for men's behavior. Researchers found, however, that when fertile, women found all men slightly more attractive. Irrespective of their cycle, flirtier men were evaluated as more attractive for sexual relationships but less for long-term relationships. Results appeared in Psychological Science. (2020-03-06)

Letrozole is a promising new treatment of male infertility, researcher says
A letrozole pill once a week restored fertility in obese, infertile men and led to their partners giving birth to two full-term, healthy babies, according to a new study from Canada. The results will be presented Thursday at the Endocrine Society's 97th annual meeting in San Diego. (2015-03-06)

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)

Big butts aren't everything to male baboons
While the female baboon's big red bottom may be an eyesore to some, it has an aphrodisiac effect on her mates. Biologists have long thought that baboon males prefer females with bigger backsides as the mark of a good mother, but a Duke study reveals that the size of a female's swollen rump doesn't matter as much as previously thought. (2015-04-20)

'Wild idea' opens possible new frontier for preventing ovarian cancer
A laboratory study published in Clinical Cancer Research offers a new hypothesis about how ovarian cancer forms and suggests how it might be prevented. The study is the first to show that the natural stiffening of the ovaries called fibrosis occurs with age. It also suggests that the diabetes drug metformin may be able to halt this process. (2019-10-09)

Oral contraceptive pills protect against ovarian and endometrial cancer
A comprehensive study from Uppsala University, involving more than 250,000 women, shows that oral contraceptive use protects against ovarian and endometrial cancer. The protective effect remains for several decades after discontinuing the use. The study is published in the journal Cancer Research. (2020-12-17)

Cedars-Sinai researchers: Fat behaves differently in patients with polycystic ovary syndrome
Fat tissue in women with polycystic ovary syndrome produces an inadequate amount of the hormone that regulates how fats and glucose are processed, promoting increased insulin resistance and inflammation, glucose intolerance and greater risk of diabetes and heart disease, according to a study conducted at the Center for Androgen-Related Research and Discovery at Cedars-Sinai Medical Center.
