Hello,
Since the post was pint out @

"This theory has, however, not been firmly established and further research is necessary."

Then why not to learn the benefits of masturbations as follows:

Breaking News On Prostate Health

What is the connection between an enlarged prostate gland and
masturbation? Read on ....

Masturbation has been a taboo subject and associated with a large number
of falsehoods. Perhaps it was believed that human beings are not
entitled to have sexual pleasure unless it is shared !

With a change in perceptions and the acceptance of the biological need
for sex, such myths have been discredited. Now, masturbation as a tool
for self stimulation and prostate health has become a subject matter of
studies conducted all over the world. While there is an inherent risk of
infections and sexually transmitted diseases during sexual intercourse,
masturbation is the manual, self-stimulation of the genital organs and
there is absolutely no risk.

Research Study 1.

The Cancer Council Victoria in Australia has just announced the results
of a study into the relationship between prostate cancer and ejaculation
in men. Masturbation is no longer a taboo subject and the study
published in the British Journal of Urology International suggests that
frequent ejaculation by whatever means will keep the gland healthy. The
more the ducts from the gland are cleared of debris and toxins,
including any carcinogens in the prostatic fluid, the better it is.

New findings on prostate cancer risk and sexual activity

Thursday 17 July, 2003

The Cancer Council Victoria has announced the results of research
undertaken into the relationship between prostate cancer and ejaculation
in men aged under 70.

A research team led by Professor Graham Giles, Director of the Cancer
Council's Cancer Epidemiology Centre, has found that there is evidence
that the more frequently men ejaculate between the ages of 20 and 50,
the less likely they are to develop prostate cancer.

The researched showed that the protective effect of ejaculation is
greatest when men in their twenties ejaculated on average seven or more
times a week. This group were one-third less likely to develop
aggressive prostate cancer when compared with men who ejaculated less
than three times a week at this age.

Professor Giles said, "We looked at a number of different aspects of
sexual activity including the number of sexual partners, the frequency
of ejaculation, as well as the number of times men ejaculated at
different ages, from their twenties through to their fifties.

"The study looked at ejaculation in the context of intercourse with
another person, masturbation, nocturnal emissions etc.

"This is a different approach from previous studies which have mostly
looked at links between sexual intercourse and prostate cancer.

"Our research indicates that there is no association between prostate
cancer and the number of sexual partners, which argues against infection
as a cause of prostate cancer in the Australian population."

"We also found no association between maximum number of ejaculations in
a 24 hour period and prostate cancer. Therefore, it is not men's ability
to ejaculate that seems to be important.

"While it is generally accepted that prostate cancer is a hormone
dependent cancer, apart from age and family history, its causes are
poorly understood."

"For this reason, our explanations are fairly speculative - one possible
reason for the protective effects of ejaculation may be that frequent
ejaculation prevents carcinogens building up in the prostatic ducts."

"If the ducts are flushed out, there may be less build up and damage to
the cells that line them."

"However, this is only one study and our findings require further
corroboration in other studies.

The research was conducted with men who were under the age of 70 when
they were diagnosed with prostate cancer, and with a group of similarly
aged healthy men. There were 1079 men with prostate cancer and 1259
healthy men in the study. The men were from Melbourne, Sydney and Perth.

The men filled in a confidential questionnaire which sought details of
their sexual activity at various times in their life. The results of the
survey were treated confidentially.

Professor Giles said, "We believe that the men who participated in the
study were likely to have been honest about their sexual activity
because of the way the research was conducted, particularly using a
questionnaire that men filled out themselves, and respecting their
privacy."

"The fact that we did not find any association with the number of sexual
partners argues against the possibility of the finding in regard to
ejaculation being due to bias, as if this was the case we would have
expected both associations to be positive."

The project involved researchers from The Cancer Council Victoria, The
University of Western Australia, The European Institute of Oncology and
the Dunedin Medical School, University of Otago, New Zealand.

The research was funded by the National Health and Medical Research
Council and supported by funding from Tattersall's and The Whitten
Foundation, as well as The Cancer Council Victoria.

The research is being published in the /British Journal of Urology
International/ vol 92, p 211.

Research Study 2

A recent US study - the biggest one to date- suggests that frequent
sexual intercourse and masturbation protects men against a common form
of cancer. The study, which followed nearly 30,000 men over eight years,
showed that those that ejaculated most frequently were significantly
less likely to get prostate cancer.

In the US study, the group with the highest lifetime average of
ejaculation - 21 times per month - were a third less likely to develop
the cancer than the reference group, who ejaculated four to seven times
a month. And just think ...Michael Leitzmann, at the National Cancer
Institute in Bethesda, Maryland, and colleagues set out to test a
long-held theory that suggested the opposite - that a higher ejaculation
rate raises the risk of prostate cancer. At the start of the study, the
men filled in a history of their ejaculation frequency and then filled
in further questionnaires every two years.

Men of different ages varied in how often they ejaculated, so the team
used a lifetime average for comparisons. However, whilst the findings
are statistically significant, Leitzmann remains cautious.A further
reservation is that the benefit of ejaculation was less clear in
relation to the most dangerous, metastasising form of prostate cancer,
compared to the organ-confined or slow-growing types.

Please be smart and think logically regarding the matter.
