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.

Researchers have captured the very first real-time, three-dimensional images and videos of a human embryo implanting into collagen designed to mimic uterine tissue —a key stage in reproduction ...

Sixty percent of miscarriages are caused by the failure of an embryo—the developmental stage before a fetus—to implant in the ...

The creation of a human embryo without sperm or egg also goes beyond what we have seen in previous artificial reproductive technology and genetic engineering techniques.

Scientists say they are closer than ever to growing human eggs from body tissue. At George Church’s lab at the Wyss Institute of Harvard, researchers say this process could open up reproductive ...

Human reproduction rewritten? Could lab-grown egg cells revolutionize fertility treatments and stem the menopause? Written by Charlie Osborne, Contributing Writer April 8, 2012, 8:44 p.m. PT ...

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 ...

Beyond future space colonies, there is also a more pressing need to understand the effects of space on the human reproductive system. No one has ever become pregnant in space—yet.

Microplastics have been discovered in human follicular fluid and semen, according to new research, raising concerns about possible risks to reproductive health.
