Question
Male masturbation: Does frequency affect male fertility?
Does frequent masturbation affect male fertility?
Answer
from Erik P. Castle, M.D.
Frequent male masturbation isn't likely to have much effect on your ability to get your partner pregnant. Frequent orgasms (ejaculations) caused by masturbation don't reduce sperm count or sperm quality.
Having sexual intercourse with ejaculation several times a week will maximize your chances of getting your partner pregnant, whether you masturbate or not.
