Masturbation reduces the risk of prostate cancer, but…

Two news from the Inopressa website: good and...

A study conducted by Australian scientists confirms that frequent masturbation can help men under the age of 50 to reduce the risk of prostate cancer in older age. Experts from the Melbourne Cancer Research Center, who conducted the study, asked more than 2,000 men about their sexual habits. Their answers showed that those who engaged in masturbation, the chances of getting prostate cancer are three times lower than those who were not fond of masturbation (Tatiana Lopez, La Voz de Galicia, 23/4/2008). 

And the next news has gone for the third year, but it is, perhaps, even better:

Sex with a partner is 400% better than masturbationLovers are well aware that men usually need a break after orgasm, a "recovery period".

It is also known that an orgasm during sexual contact with a partner satisfies more than an orgasm during masturbation. Now scientists believe that these two phenomena may be interrelated.

After orgasm, the hormone prolactin is released in the body of men and women and enters the bloodstream. This hormone gives us a feeling of satisfaction, reflecting the effect of dopamine, which is produced at the moment of sexual arousal.

Stuart Brody from Paisley University in the UK and Tilman Kruger from the Swiss Federal Institute of Technology in Zurich measured the level of prolactin in the blood of volunteers of both sexes who, after watching pornographic films, masturbated or had sex to achieve orgasm in the laboratory.

To their surprise, in both men and women, the increase in prolactin levels in the blood as a result of orgasm after sexual contact with a partner turned out to be 400% higher than from orgasm during masturbation.

This explains why we experience more pleasure from sexual intercourse with a partner than reaching orgasm through masturbation, says Brody. Since elevated prolactin levels are associated with erection problems, it also helps to understand why men need rest after sex (NewScientist, 04/22/2006).
