Study suggests pregnancy and ovarian function are risk factors for coronary artery disease
Coronary artery disease (CAD) is a leading cause of death in both men and women. Women are more susceptible to CAD during the menopause transition because of loss of ovarian function leading to estrogen deficiency. A new study suggests the risk of CAD could be identified earlier by looking at reproductive risk factors. Study results are published online today in Menopause, the journal of The North American Menopause Society (NAMS). (2020-08-05)

Herbicide harming marsupial health and development, research finds
Researchers exposed the adult female tammar wallabies to atrazine contaminated water throughout pregnancy, birth and lactation to help establish the extent of harm being caused by the chemical. They then examined the reproductive development of their young by assessing their growth and development to establish that the herbicide is causing major abnormalities in the male reproductive system in many animals. (2020-08-05)

Penis microbiota predicts if a man's female partner will develop bacterial vaginosis
Penile microbiome composition can vary; however, the presence of some bacterial vaginosis-related bacteria correlates with bacterial vaginosis onset in their female partners. Results highlight 10 bacteria that could be used to accurately predict bacterial vaginosis incidence in women. The study suggests that treatment manipulating the penile microbiome may reduce BV incidence in sex partners. (2020-08-04)

Monkeying around: Study finds older primates father far fewer babies
Older male rhesus monkeys sire fewer offspring, even though they appear to be mating as much as younger monkeys with similarly high social status. Sperm quality or quantity, or the survival of infants, may decline with the age of the would-be father, the new study suggests. A new study from Washington University in St. Louis has implications for understanding some age-related aspects of male reproductive health in primates, including humans. (2020-08-03)

Iowa State University scientists examine reproductive effects of glyphosate in mice
A pair of recently published studies analyzed how ovarian function in mice responded to various levels of exposure to glyphosate, a chemical extensively used to kill weeds. The results showed exposure changed the level of some ovarian proteins but did not impact ovarian steroid production, an indication glyphosate may not adversely affect reproduction. (2020-07-28)

Overweight and obesity are associated with a low sperm quality
Researchers from the Rovira i Virgili University in collaboration with researchers from the University of Utah have carried out a systematic review and meta-analysis evaluating the association between adiposity (normal weight, overweight, obesity, and low weight) and the sperm quality. Overweight and/or obesity were associated with low semen quality parameters and underweight category was likewise associated with low sperm normal morphology. According to the researchers, this work demonstrates the importance of adiposity in semen quality. (2020-07-27)

Same-day IUD placements hard to come by in Ohio, study finds
Though same-day access to IUDs increases the likelihood a woman will get the reproductive health care she wants and decreases the chance she'll become pregnant when she doesn't plan to, most providers in Ohio don't offer the service, a new study has found. (2020-07-27)

Early menstruation linked to increased menopause symptoms
Early menstruation increases the likelihood of hot flushes and nights sweats decades later at menopause, according to a University of Queensland study. (2020-07-22)
