A gene that normally ensures sperm quality in fruit flies can be hijacked by 'selfish chromosomes' to bias inheritance, showing how some genetic elements determine which sperm survive...
Knocking out a single gene on the Y chromosome has been found to cause infertility in male mice...
Organoids grown from testicular cells of young mice have shown characteristics of normal mouse testes and have potential to produce sperm...

Dr Simon Fishel, founder of the CARE Fertility Group, has a long and distinguished career behind him. As a young biochemist he began his research career at the University of Cambridge with IVF pioneer Professor Robert Edwards, who together with Dr Patrick
Scientists in China have used stem cells to create rudimentary sperm that successfully fertilised mouse eggs to produce healthy offspring...
Men previously considered sterile have successfully fathered children thanks to a newly improved technique called round spermatid injection (ROSI)...
Healthy mice have been born using sperm grown in the lab from a sample of cryopreserved testicular tissue...
Dancing cocks (that's male chickens, cheeky) in tight speedos fighting over a scantily clad egg might not be the first thing that comes to mind when thinking about PhD theses. However, that just about describes this year's winner of Science magazine's Dance Your PhD contest...
