Key regulator of male fertility identifed


When it comes to male reproductive fertility, timing is everything. Now scientists are finding new details on how disruption of this timing may contribute to male infertility or congenital illness. Researchers are identifying the key molecular and genetic switch that activates production of healthy male sperm — but only when the time is right.

Cell-based therapy success could be boosted by new antioxidant

Lab tests found that the human-made molecule — a type of antioxidant — helps to shield healthy cells from damage such as would be caused when they are transplanted into a patient during cell therapy.
