Sperm are constantly replenished in the adult male body. Understanding the workings of stem cells responsible for this replenishment is expected to shed light on why male fertility diminishes with age, and possibly lead to new treatments for infertility.
Compared with those born from nonsmoking mothers, young children whose mothers smoked while pregnant were 1.24-times more likely to show signs of kidney damage, research shows.
Women with a history of recovered acute kidney injury had an increased rate of preeclampsia and delivered infants earlier than women with a history of normal kidney function, new research concludes.
In the first study of its kind, environmental health scientists and neuroscientists examined the effects of the compound bisphenol S (BPS) on maternal behavior and related brain regions in mice. They found subtle but striking behavior changes in nesting mothers exposed during pregnancy and lactation and in their daughters exposed in utero.
Preterm birth — birth before 37 weeks of pregnancy — affects up to one in every six births in the United States and many other countries. In a recent study has discovered the critical function of a type of mother’s immune cells — B lymphocytes — in resisting preterm birth triggered by inflammation.
The prevalence of past-month marijuana use among reproductive-aged women rose from 2.4 percent in 2002 to 3.9 percent in 2014, an increase of 62 percent. Past-month marijuana use was highest among those ages 18 to 25 years, reaching 7.5 percent in 2014, and significantly higher among those ages 26 to 44 years (2 percent).
A new study is the first to reveal how pregnancy causes long-lasting alterations in brain structure, probably related to improving the mother’s ability to protect and interact with the child.
Vitamin B3 nicotinamide may help treat pregnant women who suffer from preeclampsia by preventing strokes and in some cases, even stimulating the growth of their fetus, research indicates.
Zika-linked abnormalities that occur in human fetuses are more extensive and severe than previously thought, with 46 percent of 125 pregnancies among Zika-infected women resulting in birth defects in newborns or ending in fetal death, researchers report.
Strokes and heart attacks are rare for women with diabetes who use hormonal contraception, with the safest options being intrauterine devices (IUDs) and under-the-skin implants, new research shows.
