Anti-Depressants Can Damage Men's Sperm

NEW YORK - Add anti-depressants to the list of substances that can damage men’s sperm and potentially impair their fertility.
In a new study, New York researchers report that as many as half of men taking the anti-depressant paroxetine (brand names, Seroxat and Paxil) have higher levels of sperm fragmentation.
The study was published online today by the journal Fertility & Sterility.
“It’s fairly well known that SSRI anti-depressants negatively impact erectile function and ejaculation. This study goes on step further, demonstrating that they can cause a major increase in genetic damage to sperm,” said Dr. Peter Schlegel, the study’s senior author and professor of reproductive medicine at Weill Cornell Medical College in New York.
“Although this study doesn’t look directly at fertility, we can infer that as many as half of men taking SSRIs have a reduced ability to conceive. These men should talk with their physicians about their treatment options,” he added.
The study followed 35 healthy men who took paroxetine for five weeks. Tests were used to examine DNA fragmentation, which occurs when sperm DNA is missing pieces of the genetic code. The results showed that 50 percent of men had signs of abnormal DNA fragmentation while taking the drug, compared with less than 10 percent at the start of the trial.
The men’s sperm returned to normal after discontinuing the drug.
Dr. Cigdem Tanrikut speculated that the anti-depressant caused mens’ sperm to slow down as it makes its way through the male reproductive tract. Sperm gets “hung up,” she said in a statement, allowing it to age and become damaged.
The amount, concentration and motility of sperm were not significantly changed by the medication.
Though men may not know it, sperm can be damaged by various substances, including smoking, alcohol, heat, anabolic steroids, drug abuse, sexually transmitted diseases and some environmental exposures.
