Older men had a higher overall proportion of sperm with abnormal morphology, lower sperm vitality and a higher proportion of sperm tail defects, cytoplasmic droplets and teratozoospermia index. Handelsman DJ and Staraj S Imagine that the testicle made 10 sperm an hour. Generally, men should identify their own frequency by determining how strong and refreshed they feel after and between intercourse sessions.
