Low sperm, high cancer risk

Men with low sperm production face increased cancer risk.

MEN who are diagnosed as azoospermic – infertile because of an absence of sperm in their ejaculate – are more prone to developing cancer than the general population, a study led by a Stanford University School of Medicine urologist has found. A diagnosis of azoospermia before age 30 carries an eight-fold cancer risk, the study says.
