A recent study published by Pam Factor-Litvak in the journal, Fertility and Sterility, suggests that men who feel stressed have fewer and slower sperm. The study includes 193 men, aged 38-49, who rate how stressed they felt in various life situations. The study found that life stress degraded the quality of semen possibly by lowering levels of testosterone. This study, as well as others, reinforces the importance of stress management during fertility attempts.
