Drugs that enhance glycolysis, the release of sugar through the breakdown of glucose, have been found to increase the self-renewal capacity of sperm stem cells.
Female Chickens Store Sperm From Multiple Males With Help From Fat Cells
Droplets of fat transferred from female cells to sperm cells may contribute to keeping sperm alive for long periods of time.
Crocodile Sperm Swim Like Human Ones
Studying crocodiles could help us understand male infertility in humans, since their sperm also continue to mature as they ‘swims’ towards the egg.

Six healthy monkeys have been born using sperm grown from testis tissue transplanted onto the backs of mice.
‘Smelly Egg Gas’ Might Help With Male Infertility
Hydrogen sulphide, the gas which gives rotten eggs their characteristic smell, could be used to mitigate heat-induced testicular injury.
Keeping Mammalian Sperm Production Flowing
The maintainance of stem cells during mouse spermatogenesis depends on hierarchical differences in response to retinoic acid, study says.
Cell Fusion Ensures Only One Sperm Gets Through
Research shows that flowering plants prevent polytubey through the extremely rare process of cell fusion.
