Masterbation for sperm collection

Refrain from any sexual activity including masturbation for at least 2 days and no more than 10 days. Longer or shorter periods of abstinence may result in a lower sperm count or decreased sperm motility. A private room is available for semen collection within close proximity of our laboratory and is recommended for collection. The semen specimen should be obtained by masturbation.
