With human research trials resulting in dozens of successful deliveries in the US and abroad, doctors move toward offering the surgery clinically, while working to learn all they can about uterine and transplant biology from the still-rare procedure.

CRISPR and other innovations are likely to open up a wealth of new options for how people have children.

A combination of approaches, including uterus transplantation and the joining of two animals’ circulatory systems, allowed males to bear pups, according to a preprint. But some experts say the experiments were not justified.  

The hardy animals were pulled from the permafrost in Siberia, giving scientists the opportunity to study how they survive extreme conditions.

A single gene called BMP11 regulates not only the size and proportions of a water strider’s massively long third legs, but also how it uses the limbs in fights.

Following vaccination, some women claim their periods have changed, leading to rumors about how the shots affect recipients’ reproductive systems, and even others’ by proxy.  

Female mice modeling the hormonal disorder can pass symptoms down for several generations, likely via changes in genome methylation that are similarly observed in women with PCOS.

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.

Meet Shoko Sakai, a scientist at Kyoto University's Center for Ecological Research, who explains some of the remarkable reproductive adaptations of plants.

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

In most vertebrates, the absence of adaptive immunity would be catastrophic, but in some deep-sea angler fish species, it enables their “wild” and “wacky” mating habits.

Fossils from Newfoundland, Canada, reveal the extensive connections that existed among Earth’s earliest, sea-dwelling animals.

Before the joey is born, another pregnancy has already started.

A phthalate commonly found in shampoos, cosmetics, and cleaning products disrupts reproduction in worms.

Building simulations based on real genetic data, researchers conclude Gattaca-like tactics to choose the traits of future offspring would yield little payoff.

A protein present in the ejaculate of male fruit flies activates long-term memory formation in the brains of their female partners.

It could be a throwback to a mechanism that induces ovulation during sex, researchers propose, but not everyone thinks the results can be extrapolated to people.

Groups of corals release all of their eggs and sperm once a year, but the timing of their spawning is under threat from climate change.

Funnel-web spiders change the timing of their distinct courtship behavior depending on what microbes they’re carrying.
