ScienceDaily (Sep. 26, 2008) — Exposure to an excess of sexual steroids, like testosterone, during fetal development may be a potential risk factor for low sperm count and motility, according to a new study.

“The majority of disorders affecting sperm count in humans are originated during fetal life,” said Professor Sergio Recabarren of the University of Concepcion in Chillan, Chile and lead author of the study. “A developing fetus is very vulnerable to its environment, and when that environment is exposed to excess sexual steroids, it may have a significant deleterious effect on a male offspring’s fertility.”
