Hi, welcome to HCM. Thanks for asking your query at this forum. We understand your concern. I have read your question carefully and understood it. I will try my best to answer it. Your concern is right. Due to excessive masturbation there is reduction in quantity and quality of semen. Semen is made up of sperms and secretions of prostate and other genital glands. Sperm production occurs at a constant rate in body, it is collected in seminal vesicles (a storage organ) and get discharged at the time of ejaculation. Frequent ejaculations may deplete the sperm and seminal fluid store and during subsequent orgasm ejaculated semen may be less in quantity and quality. There are few good natural ways to increase quality and quantity of sperm as below:- - Take healthy balanced diet with lots of fresh fruits, salads and sprouts; - Take vitamin supplement like folate, Vit B6, biotin and vitamin E in moderate amount; - Avoid tobacco, alcohol or any other drug; - Reduce the frequency of sexual act to once or twice a week. Hopefully you will try and get benefited with above mentioned measures.
