New research presented at the 41st Annual Meeting of the European Society of Human Reproduction and Embryology (ESHRE) reveals the presence of microplastics in human reproductive fluids, raising ...

New research has mapped the cell types that specialize to form reproductive organs in both sexes, identifying key genes and ...

Scientists have detected microplastics in human semen and follicular fluid, the liquid that surrounds an egg in an ovarian follicle. "This is not an isolated finding –– it appears to be quite common," ...

Scientists have found significant quantities of microplastics present in human and canine testicles, raising concerns surrounding their potential impact on the human reproductive system. Microplastics ...

Microplastics are thousands of times smaller than a grain of rice, and they can wreak havoc on the human reproductive system. A new study found them in the testes of both humans and dogs. The rise of ...

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 ...

Despite the fact that we all start out as an egg cell in one of our mother's ovaries, these human reproductive organs are surprisingly under-studied. Scientists have been working on creating in vitro ...

A comparison of seven nonhuman primate species has found both similarities and differences among the effects of age on female reproduction. Reproductive senescence has two components. One is fertility ...

A Vermont elementary school says it will no longer use the words “male” or “female” when teaching fifth-grade students about puberty and human reproductive systems. Families of students at Founders ...

Polluted, noisy and crowded urban environments can impair physical performance. Living in modern cities may not be good for human health, according to evolutionary scientists from Loughborough ...
