Since China ended its one-child policy allowing all families to have up to two children, an additional 90 million women have become eligible to have a second child. But new UBC sociology research suggests the new universal two-child policy could be negatively affecting women's status and gender equality.
Princeton researchers identified a key protein in old, poor-quality C. elegans eggs. When they blocked this protein midway through the fertile window, the equivalent of a woman in her early thirties, they successfully extended egg viability beyond the normal span. Another experiment that knocked out this protein's genes entirely extended the worms' fertility by about 10 percent. If applied to humans, that could represent a 3- to 6-year extension of female fertility.
University of Utah Health developed the HER Salt Lake Contraceptive Initiative to evaluate women's contraception choices if cost is not a factor. The research findings are published in the February 22 issue of the American Journal of Public Health.
Midwife-friendly laws and regulations tend to coincide with lower rates of premature births, cesarean deliveries and newborn deaths, according to a new US-wide 'report card' that ranks all 50 states on the quality of their maternity care.
A new Tel Aviv University study identifies novel molecular biomarkers of preeclampsia, a sudden pregnancy complication, signaling the potential for an early diagnostic blood test.
Scientists have identified a hormone that could help prepare the womb lining for pregnancy, research shows.
Researchers find evidence supporting both male-male competition and female choice as factors in the evolution of the enlarged male nose in proboscis monkeys.
A child's growth and development is affected by the health and lifestyles of their parents before pregnancy - even going back to adolescence - according to a new study.

Women in treatment for eating disorders need more nuanced information about reproductive health, and more thought needs to be given to how and why fertility information is delivered, according to new research from the University of East Anglia (UEA).
A highly effective tail is needed in order for a sperm to be able to swim, and for a baby to be conceived. By using cryo-electron tomography, researchers at the University of Gothenburg -- working in partnership with researchers in the USA -- have identified a completely new nanostructure inside sperm tails.
