Zika targets the male reproductive system, at least in mice, say researchers. Three weeks after Zika infection, male mice had shrunken testicles, low levels of sex hormones and reduced fertility. The results suggest that Zika infection may interfere with men’s ability to have children.
Sperm and mathematics don’t appear to be the likeliest of bedfellows, but new research bringing the two together could lead to devices that could cut infertility rates.
Celebrity news reports over the past four decades appear to have contributed to the changing makeup of the traditional American family by helping to destigmatize out-of-wedlock childbirths in the United States, according to a study.
Going hungry at an early age can cause lifelong health problems. But the extent of malnutrition’s damage depends on mom’s diet too — at least in worms. A new study of the tiny nematode worm C. elegans finds that young worms that don’t get anything to eat in the first few days of life are buffered from early starvation’s worst effects if their mothers had also been underfed.
Vitamin D supplements are less effective at raising vitamin D levels in pregnant women if they deliver their babies in the winter, have low levels of vitamin D early in pregnancy or gain more weight during pregnancy, a new study has shown.
Men can take birth control shots to prevent pregnancy in their female partners, according to a new study. Researchers are still working to perfect the combination of hormonal contraceptives to reduce the risk of mild to moderate side effects, including depression and other mood disorders.
Epidural anesthesia may do more than relieve pain during labor; in some women it may decrease the likelihood of postpartum depression, suggests a preliminary study.
An increase in the frequency of polymorphic variants among infertile patients compared with fertile donors suggest they have an impact on fertility, report scientists.
The U.S. Preventive Services Task Force (USPSTF) recommends providing interventions during pregnancy and after birth to support breastfeeding.
A family of small RNA molecules affects the development of cells that give rise to the placenta — an organ that transfers oxygen and nutrients from mother to fetus — in ways that could contribute to a serious pregnancy complication, researchers report.
