Is male fertility affected by stress?

Philip Werthman, FACS (Director, Center for Male Reproductive Medicine) gives expert video advice on: Is male fertility affected by stress?; What are the emotional consequences associated with infertility and impotence? and more...

I believe male infertility can be impacted by stress. We see that sperm counts can fluctuate over time, and fluctuate with the environment the man is in, with what he ingests, with the condition of his sleep cycle, so certainly stress can affect sperm production in some way. What it is not is consistent among different men, because different men handle stressors differently, and their bodies handle sperm production differently.
