Do valium, xanax, (alprazolam) or klonopin affect male fertility?

Probably: There are no direct studies on sperm function with these drugs but anxiety/stress can be bad for male fertility. Since these are all drugs used to treat anxiety, there may be an underlying problem.

No: Have not seen any reports of this. However, it does effect libido and erectile function, with low levels perhaps increasing those while higher levels (as with alcohol) reducing them.

No, No, Yes: Sedatives have not been shown to reduce male fertility. Some antidepressants have been shown to reduce fertility by impairing sperm dna integrity.
