Recent research findings suggest that frequent masturbation may be beneficial for men's health.
A study by the Victoria Cancer Center in Australia shows that the more men ejaculate between the ages of 20 and 50, the lower their probability of developing prostate cancer. This cancer kills 500000 men every year.
A study of 1079 prostate cancer patients and 1259 healthy men showed that men who masturbated or had sex every day in their twenties had a one-third lower chance of developing this cancer.
Giles, the leader of the research group, said yesterday that men in their 50s cannot do this.
But he said: Masturbation is not harmful to you, I don't believe in blindness or hairy palms, and there is no scientific basis for prohibiting masturbation.
This study, conducted from 1994 to 1998, investigated respondents' sexual and masturbation habits, and analyzed their responses, which are still ongoing.
Giles pointed out that this study found that semen may have a carcinogenic effect on cells in the prostate duct, and if semen is not regularly excreted, it may lead to cancer.
Ejaculate frequently to avoid semen accumulation in prostate ducts, which may become a carcinogen. He pointed out that semen concentration of 600 times can cause cancer. Semen is a strong liquid containing various chemicals, and due to its biological reactions, it may cause cancer when left idle.
