A previously unknown kind of ribosome is responsible for folding sperm proteins, which decay before fertilization if prepared by other ribosomes.

Mice rendered infertile through ovary cell–targeting mutations gave birth to seemingly normal offspring through natural mating after a virus-based gene therapy was injected into their ovaries.

Hearing others’ perspectives on infertility and pregnancy has me reconsidering my own reproductive journey.

A long-term study finds that these rhythms align at certain times of women’s lives, shedding new light on the controversial idea that lunar phases influence human reproduction.

In human male-female pairs with a less similar suite of genes for human leukocyte antigens, sperm fare better when exposed to cervical mucus.

Independently produced knockout mouse strains fail to find evidence of the bone protein’s endocrine functions, and divide researchers’ opinions.

The controversial oogonial stem cells eluded a team of Swedish researchers who mapped high-quality tissue samples of the human ovary, prompting more questions about the cells’ existence.  

A cancer patient who underwent the new fertility preservation procedure successfully gave birth five years after her immature eggs were collected.

Oxidative stress associated with aging damages ovarian cells in both humans and nonhuman primates.

Eggs from girls and from older women show higher rates of errors in chromosome number.

George Rosenkranz was part of a team in Mexico City that first synthesized norethindrone in 1951.

A study links having a male twin with women’s educational, financial, and childbearing decisions. Researchers suspect prenatal exposure to testosterone may play a role.

The girl was born in Brazil in December 2017.

A small study based on circulating RNA in the blood of moms-to-be describes a technique that could be used to help predict who’s most at risk of preterm labor.

Bigger, older mothers produce disproportionately more eggs than their smaller counterparts do.

The technique could combat infertility, but it's still not clear whether these eggs are normal and functional.

Women who ate more produce known to harbor pesticides were less likely to succeed with fertility treatment than women who ate fewer of these fruits and vegetables.

Scientists plan to use in vitro fertilization to preserve a species with only three remaining members in the wild.

An estimate derived from fertility rates concludes that at least 75 percent of our DNA has no critical utility.
