Study Identifies Genetic Fingerprint Of Healthy Sperm
The genetic fingerprinting of sperm cells-detailed in this week's issue of THE LANCET-could be a major step forward in our understanding of male infertility. Around one in six couples experience difficulty in conceiving a child, and male fertility problems account for half of assisted reproductive techniques. However, the underlying cause of... view more... (2002-09-04)
