NOT EJACULATING IS VERY DANGEROUS
TO MEN.
If you think you are a
smart boy that practices Daoism and impresses the girls with the ability of not
ejaculating, wasting your precious energy, you'd better open your eyes: this
will bring you a nice prostate cancer later.
Even if a study published
in The Journal of the American Medical Association (JAMA) does not link ejaculation frequency, a measure of sexual
activity, with a higher risk for prostate cancer, a high ejaculation frequency
may be linked to a decreased risk of prostate cancer.
Sexual activity has been
hypothesized to play a role in the development of prostate cancer since long and a link between sexual
activity and prostate cancer risk would have clinical and public health
relevance.
Michael F. Leitzmann, M.D., of the
National Cancer Institute, Bethesda, Md., and his team investigated the
association between ejaculation frequency (by
any meaning: sexual intercourse, nocturnal emission, and masturbation) and
risk of prostate cancer.
The researchers used monitoring
data from the Health Professionals Follow-up Study of 29,342 men in the U.S.,
aged 46 to 81 years, who gave information on history of ejaculation frequency
on a self-administered questionnaire and responded to follow-up questionnaires
every 2 years, from 1992 to 2000.
To assess ejaculation frequency,
subjects were demanded to report the average number of ejaculations they had
per month during the ages of 20 to 29 years, 40 to 49 years, and during the
past year.
Among the study's subjects, there
were 1,449 new cases of total prostate cancer, 953 organ-confined cases and 147
advanced cases of prostate cancer.
"In this prospective cohort
study among predominantly white men, higher ejaculation frequency was not
related to increased risk of prostate cancer.
Our results suggest that high
ejaculation frequency possibly may be associated with a lower risk of total and
organ-confined prostate cancer.
These associations were not
explained by potential risk factors for prostate cancer, such as age, family
history of prostate cancer, history of syphilis or gonorrhea, smoking, and
diet," explained the authors.
