Ejaculation Frequency and Risk of Prostate Cancer: Updated Results with an Additional Decade of Follow-up

Background

Evidence suggests that ejaculation frequency may be inversely related to the risk of prostate cancer (PCa), a disease for which few modifiable risk factors have been identified.

Objective

To incorporate an additional 10 yr of follow-up into an original analysis and to comprehensively evaluate the association between ejaculation frequency and PCa, accounting for screening, clinically relevant disease subgroups, and the impact of mortality from other causes.

Design, setting, and participants

A prospective cohort study of participants in the Health Professionals Follow-up Study utilizing self-reported data on average monthly ejaculation frequency. The study includes 31 925 men who answered questions on ejaculation frequency on a 1992 questionnaire and followed through to 2010. The average monthly ejaculation frequency was assessed at three time points: age 20–29 yr, age 40–49 yr, and the year before questionnaire distribution.

Outcome measurements and statistical analysis

Incidence of total PCa and clinically relevant disease subgroups. Cox models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs).

Results and limitations

During 480 831 person-years, 3839 men were diagnosed with PCa. Ejaculation frequency at age 40–49 yr was positively associated with age-standardized body mass index, physical activity, divorce, history of sexually transmitted infections, and consumption of total calories and alcohol. Prostate-specific antigen (PSA) test utilization by 2008, number of PSA tests, and frequency of prostate biopsy were similar across frequency categories. In multivariable analyses, the hazard ratio for PCa incidence for ≥21 compared to 4–7 ejaculations per month was 0.81 (95% confidence interval [CI] 0.72–0.92; p < 0.0001 for trend) for frequency at age 20–29 yr and 0.78 (95% CI 0.69–0.89; p < 0.0001 for trend) for frequency at age 40–49 yr. Associations were driven by low-risk disease, were similar when restricted to a PSA-screened cohort, and were unlikely to be explained by competing causes of death.

Conclusions

These findings provide additional evidence of a beneficial role of more frequent ejaculation throughout adult life in the etiology of PCa, particularly for low-risk disease.

Patient summary

We evaluated whether ejaculation frequency throughout adulthood is related to prostate cancer risk in a large US-based study. We found that men reporting higher compared to lower ejaculatory frequency in adulthood were less likely to be subsequently diagnosed with prostate cancer.

So no worries for men in Thailand, as the recommended frequencies are fully respected and exceeded:cheesy:

So the next time someone calls you a w****r  you could actually end up having the last laugh.

I can understand that survey , it's more healthy to use your body , whether it's doing exercise or sexual activities.   

Sitting on a barstool drinking all day is probably not a good idea, sex or not.

 

 

 

 

 

Has a follow up study been done?  Qualitative Analysis...What are the common themes related to blowing your wad.?   Why not use ANOVA is that data analysis?     A significant cc measurement is essential for the data anaylsis.... no blank bullets here..

 

Very interesting I have been dealing with something related to this.

Had a PSA test one month ago came out 5.0.  My father had P cancer so I was concerned as anything over 4 is an alert.  Went to the doctor for the finger wave and exam Doc said come back in a month for another test.

Now prior to the first test, I had been riding my motorbike for 4 hours, had sex twice that day, and probably was a little dehydrated.

The recent test I stayed off my motorbike, restrained from boom boom for 3 days, and drank a ton of water.

PSA result just today 2.0.

So,  ha, not sure what all this means just reporting about it.

Well but just keep going back to a nice female doctor for "the  finger" test.  It will help no end.  b

 

But seriously when I was only 17,  before I had any intercourse I suffered from prostatitis.  The test showed at that time I had an enlarged prostate ( based on what is norm I am not sure ).  My annual medicals for the last 12 years of course show the same and when I produce the medical report from 50 years ago the doctors just say that can not be right".   Well it is right so as far as I am concerned the statistical data considered as the  norm is too much of a generalisation perhaps.

Yes I guess it is true when they say ¨doctors PRACTICE medicine¨

It wasn't true in Thailand, but things are different in the USA. :sad:

Men should be masturbating more if they want to reduce their risk of developing cancer, according to the NHS.

New research published on the NHS website found the risk of prostate cancer was significantly lower in men who ejaculated at least 21 times a month through sex or masturbation.

Prostate cancer is the most common cancer in men in the UK, with more than 40,000 new cases every year.

Researchers from Harvard and Boston medical schools and universities studied 31,925 healthy men who completed a questionnaire about their ejaculation frequency back in 1992, reports the Plymouth Herald .

The men, who were aged 20-to-29 and 40-to-49, were monitored until 2010 and during that time 3,839 of them were diagnosed with prostate cancer.
