A man's ability to produce sperm may depend on his ability to handle stress, according to a study from Italy that looked at the impact of short- and longer-term stress. The researchers, who published their findings in the journal Fertility & Sterility, found that men with higher levels of both short- and long- term stress ejaculated less semen and had lower sperm counts. Men with the highest anxiety also more likely to have sperm that were deformed.
