Mounting evidence from research on nematodes to mice indicate that a father's environment, such as what he eats or if he is ...

New scientific methods could one day render animal studies—the standard in research laboratories for more than 100 ...

Research into how a father’s choices — such as diet, exercise, stress, nicotine use — may transfer traits to his children has become impossible to ignore. The standard sperm-meets-egg story posits ...

The mammals' mysterious clicks contain a stunning level of complexity, a new study shows. A group of sperm whales (Physeter macrocephalus) swims together in the Indian Ocean. For years, researchers ...

PORTLAND, Ore. — Researchers have created human embryos by taking nuclei from ordinary skin cells, placing them into donated eggs, and fertilizing them with sperm. The work is a laboratory ...

HINXTON, England — At first glance, the news sounds reassuring: sperm cells accumulate genetic mutations eight times slower than blood cells, making them among the most protected cells in the male ...

In a proof-of-concept experiment, scientists demonstrated that you can create and fertilize human eggs in the lab using sperm, genes from skin cells, and the "shells" of existing egg cells. When you ...

Creating human eggs from adult cells just got one step closer to reality. A technique used in cloning combined with fertilization and a bit of chemical coaxing caused human skin cells to produce eggs ...

In a controversial step that raises the possibility of a new kind of infertility treatment, scientists report that they have produced functional human eggs in the lab that were able to be fertilized ...

Human embryos have been developed from eggs given the DNA of adult skin cells – a feat that had previously been achieved in mice. This could one day provide a way for same-sex couples or women with ...

Microplastics have been detected in human blood, brain tissue, and even bones, where they may weaken skeletal structure and accelerate cell aging. Recent studies suggest that these particles could ...

Scientists in the Netherlands have transformed sperm cells into microscopic robots in a move that could transform the future of fertility. The team from the University of Twente, in the Netherland, ...
