A man in his early 20s received a transplant of his own sperm-producing stem cells, which had been frozen since his childhood, in an attempt to regain fertility. Doctors are waiting to see if the ...

A MAN has received the world's first sperm-making stem cell transplant in a groundbreaking experiment to reverse infertility. Jaiwen Hsu, 26, has azoospermia, a condition where no sperm is present ...

In most cells, DNA is wrapped around proteins called histones, allowing it to be loosely packed and accessible for gene activity. However, in sperm cells, histones are replaced by protamines ...
