The results cap a seven-year effort by a team of researchers to test whether an ancient, unusual cell-signaling mechanism might explain a mysterious, often fatal disease. Specifically, the work ...

Fifteen years ago, researchers working deep in Uganda's Kibale National Park watched something unsettling unfold. The Ngogo ...

Researchers are inching closer to mass-producing eggs and sperm in the lab from ordinary human cells. The technique could provide new ways to treat infertility but also open a Pandora's box. We are ...

This has implications for their role within human reproduction. Failure of chromosomal organization within human egg and sperm cells result in miscarriages and infertility. However, the mechanisms ...

A new study, which uses a genetic approach to examine this paradox, suggests ribosomopathies are caused by a sequence of mistakes at the molecular level. In this illustration, ribosomes emerge from ...

Human Reproduction is a peer-reviewed scientific journal covering all aspects of human reproduction, including reproductive physiology and pathology, endocrinology, andrology, gonad function, ...

Scientists have detected microplastics — the tiny and pervasive fragments now found in our seas, drinking water, food and, increasingly, living tissue — in human semen and follicular fluid, according ...

(RNS) — Scientists have created a human embryo without the use of sperm or an egg — a true test-tube baby. Such embryos cannot (yet) develop into full-grown human beings. Even if transplanted into a ...

SpaceBorn United wants to conduct an IVF experiment in Earth’s orbit to pave the way for long-term space missions. Egbert Edelbroek was acting as a sperm donor when he first wondered whether it’s ...

In the beginning, no one really understood how babies were made. Thinkers puzzled for millennia about how life arose from one generation to the next. But not until the 17th century did scientists ...
