Believe it or not, your genes are 50% parasite, and opportunistic at that. They tend to jump onto sperm and egg cells to replicate in the next generation, a process that can devastate an egg or sperm ...

A team of scientists at the University of Seville has identified an essential process that protects DNA integrity in reproductive cells, providing new clues about how organisms avoid genetic defects ...

A team of researchers from the US has turned DNA from human skin cells into "functional" eggs, which were able to be fertilised by sperm in a lab. While only around 10 per cent of the fertilised eggs ...

WOODS HOLE, Mass. -- While humans can’t renew their reproductive cells and organs if damaged, many invertebrates can as part of whole-body regeneration. Understanding how and why could have major ...

Scientists have built a detailed timeline of the gene activity leading up to meiosis in corn, a finding with potential implications for plant breeding as well as sexually reproductive organisms more ...

During mammalian reproduction, millions of sperm undertake a journey that only one will finish. This journey to fertilization has been commonly viewed as a race: a sea of sperm competing to get to the ...

There are countless facts regarding sperm, the male reproductive cells. For this reason, it can be hard to split truth from myth. Although many people have some knowledge about sperm, many ...

It’s not just about chromosomes. Or reproductive cells. Or any other binary metric. Many genetic, environmental and developmental variations can produce what are thought of as masculine and feminine ...

Developing egg cells conduct tests to select the healthiest of their energy-making machines to be passed to the next generation. Developing egg cells conduct tests to select the healthiest of their ...
