Sex with more than 20 women reduces risk of prostate cancer

I know that it’s been said that there are “lies, dammed lies and statistics” but the findings of a recent survey are interesting
Scientists are at a loss to adequately explain the results of a recent statistical survey in Montreal and I’m not going to speculate. However, I will refer readers to Daniel Reid’s “The Tao of Health, Sex and Longevity“, a modern guide to the ancient Taoist principles for good health.
In outlining the ancient principles that form the foundations of Traditional Chinese Medicine, Reid reveals some interesting facts that have a bearing on what follows.

According to Reid the ancient Taoist masters considered sexual energy and general health and well being to be intimately linked. Sexual energy was seen as a manifestation of Chi, or life force, and a balanced, measured approach was recommended.
However complete abstinence, such as the celibacy ordained by some religious orders, was viewed as harmful. While in contrast, habitual masturbation among older men and excessive ejaculation was also considered harmful to health.
According to Reid:
“Dr Sun repeatedly warned his male patients of the dangers involved in excessive ejaculation. He compared the situation to that of a sputtering oil lamp: just before the fuel is spent and the lamp is about to extinguish, the flame suddenly flares up brightly, then dies:
“Each and every time a man restrains himself and retains his semen it is like adding new oil to a lamp that is about to extinguish.”
This wasn’t a moral view but a judgement based purely on what was considered best for health and well being.
Likewise, promiscuous homosexual activity was considered very detrimental to health. Again this wasn’t an ethical judgement, but a conclusion based purely upon practical considerations. According to Reid:
“Taoist physicians regarded homosexuality among men … as a dangerous practise — for several reasons. First of all, Yang is by nature an active, aggressive force, and, when two aggressive forces meet, a fundamental conflict of energies and intentions results. male homosexuality requires that one partner yield to the other by adopting the female role, both physically and psychologically, and when this practise becomes a habit it completely undermines the fundamental role of Yang in the order of nature. Looking at this situation of Yang conflict at a microscopic scientific level, when the sperm from two different men are mixed together and observed under magnification, they may clearly be observed fighting one another in a desperate struggle for supremacy…
“Ancient Taoist physicians noted a pathological condition called ‘Dragon Yang Syndrome’ which occurred exclusively among promiscuous male homosexuals”.

Sex with more than 20 women reduces risk of prostate cancer

There’s good news for the Casanovas of the world – sleeping with numerous women could help to protect men from prostate cancer, according to a new study.
Researchers at the University of Montreal and INRS-Institut Armand-Frappier found that men who had slept with more than 20 women during their lifetime were 28 per cent less likely to develop the disease.
They were also 19 per cent less likely to develop an aggressive type of cancer, compared to those who had had only one female sexual partner.
However, the same did not apply to gay men, according to the Canadian scientists. They found that having more than 20 male partners doubled the risk of prostate cancer and made an aggressive cancer five times more likely. Sleeping with one male partner did not affect the risk.
Meanwhile, men who were virgins were almost twice as likely to be diagnosed with prostate cancer as those who were sexually experienced.
The findings are from the Prostate Cancer & Environment Study in which 3,208 men answered questions about their lifestyle and sex lives.
Of these men, 1,590 were diagnosed with prostate cancer between September 2005 and August 2009, while 1,618 men were part of the control group.
Overall, men with prostate cancer were twice as likely as others to have a relative with cancer, but the study also found a possible link with their number of sexual partners.
Lead researcher Professor Marie-Elise Parent, from the University of Montreal, said: “It is possible that having many female sexual partners results in a higher frequency of ejaculations, whose protective effect against prostate cancer has been previously observed in cohort studies.”
According to one theory, large numbers of ejaculations may reduce the concentration of cancer-causing substances in prostatic fluid, a constituent of semen.
They may also lead to fewer crystal-like structures in the prostate that have been associated with prostate cancer.
Suggesting why the same did not apply to male partners Professor Parent admitted she could only provide “highly speculative” explanations.
One explanation she said “could be that anal intercourse produces a physical trauma to the prostate”.
The age at which men first had sexual intercourse, and the number of times they had been infected by a sexually transmitted disease, had no bearing on prostate cancer risk.
A total of 12 per cent of the group reported having had at least one sexually transmitted infection (STI) in their lifetime.
Professor Parent added: “We were fortunate to have participants from Montreal who were comfortable talking about their sexuality, no matter what sexual experiences they have had, and this openness would probably not have been the same 20 or 30 years ago.
“Indeed, thanks to them, we now know that the number and type of partners must be taken into account to better understand the causes of prostate cancer.”
On the question of whether promiscuity might now be recommended in health advice to men, she said: “We’re not there yet.”
