Masturbation protects against prostate cancer: study
LONDON - A new study suggests frequent masturbation by men in their 20s
provides protection against prostate cancer later in life.
Scientists in Australia determined that men in their 20s who ejaculated
more than five times a week were a third less likely to develop
aggressive prostate cancer later in life.
The study suggests ejaculation by means of masturbation provides better
protection than ejaculation in sexual intercourse because men can pick
up infections from intercourse that actually increase the risk of
getting prostate cancer.
The Australian team was headed by Graham Giles of The Cancer Council of
Victoria in Melbourne.
The team asked 1,079 men with prostate cancer to detail their sexual
habits. The responses were compared with those of 1,259 healthy men.
The team concluded that the more men between the ages of 20 and 50
masturbate, the less likely they are to develop prostate cancer. The
study emphasizes that this is especially so for men in their 20s.
"The more you flush the ducts out, the less there is to hang around and
damage the cells that line them," Giles said in New Scientist magazine.
"Masturbation is part of people's sexual repertoire," said Anthony
Smith, deputy director of the Australian Research Centre in Sex, Health
and Society at La Trobe University in Melbourne. "If these findings hold
up, then it's perfectly reasonable that men should be encouraged to
masturbate."
