Doctor Katarzyna Koziol injects sperm directly into an egg during IVF procedure called Intracytoplasmic Sperm Injection at Novum clinic in Warsaw(Reuters Health) – A man’s ability to produce sperm may depend on his ability to handle stress, according to a new study from Italy.

Researchers found that men with higher levels of both short- and long-term stress and anxiety ejaculated less semen and had lower sperm concentration and counts. Men with the highest anxiety levels were also more likely to have sperm that were deformed or less mobile.

But one fertility researcher not involved in the new work said it’s hard to know how the results apply to the general population because the research included men who were already seeking treatment at a fertility clinic.

“Do you become stressed from becoming infertile or is stress causing infertility?” asked Tina Jensen from Rigshospitalet in Copenhagen, who has studied the effects of environmental factors on sperm quality.

Previous research has found that men going through fertility treatment or evaluation have higher stress levels than the average person, and some studies have also shown links between stress and sperm quality, according to the Italian researchers, led by Elisa Vellani of the European Hospital in Rome.
