Stem cell IVF could enable same-sex couples and single parents to have genetically related children. It’s time to think ...

(Reuters) -Human skin cells may one day be used to create functional human eggs in a step toward helping women have their own genetic children when their natural eggs are dysfunctional, according to ...

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 ...

Older mice have more new mutations -- changes in DNA sequence that occur in the individual rather than being inherited from a parent -- than younger mice in the genomes of their mitochondria, ...

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 known that sex-determination in vertebrates happens in the germ cells, a body's reproductive cells, and the somatic cells, the cells that are not reproductive cells. Yet they have not ...

New research has mapped the cell types that specialise to form reproductive organs in both sexes, identifying key genes and signals that drive this process. The findings offer important insights into ...

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 ...

The fruit fly Drosophila is powerful for studying development and disease and there are many tools to genetically modify its cells. One tool, the Gal4/UAS system, has been a mainstay of Drosophila ...

Scientists have separated the sperm which carry X and Y chromosomes, in a study which could one day have "colossal" implications for choosing the sex of animals including humans. Sperm carry either an ...
