One of the most common types of cancer afflicting men, prostate cancer, is known to be risky for men above fifty years. It is estimated that annually about 35,000 men in the United Kingdom suffer cancer of the prostate. Almost 10,000 of them do not survive the disease.
During the study, the research team noted the sexual habits of 1,000 men with prostate cancer and 1,250 healthy men. The study revealed that those men who had frequent ejaculations between 20 and 50 years of age received adequate protection against the risk of prostate cancer.
So, how does ejaculation during masturbation offer such protective benefits? Is it the same with sexual intercourse?
During ejaculation, carcinogens are flushed out from the prostate gland. This happens when the prostate gland produces a fluid during ejaculation that energizes the sperms and prevents them from sticking to one another. Dr. Graham Giles, of the Cancer Council Victoria in Melbourne, added, "It's a prostatic stagnation hypothesis. The more you flush the ducts out, the less there is to hang around and damage the cells that line them."
According to Dr. Giles, sexual intercourse may not have the same effect due to the risk of sexually transmitted diseases. STD's could only escalate the risk of cancer rather than mitigate it. "Had we been able to remove ejaculations associated with sexual intercourse, there should have been an even stronger protective effect of ejaculations," he said.
Happy with the findings of the study, Anthony Smith, deputy director of the Australian Research Centre in Sex, Health and Society at La Trobe University in Melbourne, said, "Masturbation is part of people's sexual repertoire. If these findings hold up, then it's perfectly reasonable that men should be encouraged to masturbate."
