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 ...

Chinese researchers are developing a humanoid robot with an artificial womb designed to replicate the entire human pregnancy process from conception to birth. This ambitious project, though raising ...

Scientists have identified microplastics in over two-thirds of ovarian follicular fluid and more than half of semen samples, suggesting widespread internal exposure. The findings spotlight a growing ...

Recently, scientists have reviewed the existing literature to understand how space travel, space radiation, and microgravity affect human reproductive functions. This review was published in Npj ...
