Harvard study tells you what the healthiest sex frequency is

Harvard study tells you what the healthiest sex frequency is.

For Prostate Cancer (PCa), sexual activity is a highly related lifestyle factor, and it may have an impact on the occurrence of prostate cancer in many ways. However, the link between sexual activity and prostate cancer is still controversial.

Among them, there are two representative views:

The first is that frequent sexual activity increases the risk of prostate cancer.

In the first view, one of the more well-known mechanisms is that sexual activity increases androgen activity in the body, so frequent sexual activity may indirectly increase the risk of prostate cancer.

Another mechanism is that sexual activity increases the chance of exposure to infectious agents; a 2008 Cambridge University study found that frequent masturbation increases the chance of prostate cancer.

The second is that frequent sexual activity reduces the risk of prostate cancer.

In the second view, the one that advocates frequent activity, there are different mechanistic assumptions. One of the hypotheses suggests that, in the absence of other indicators of physical abnormalities, men who ejaculate less often have an increased risk of prostate cancer. This hypothesis is based on the mechanism that frequent ejaculation helps to excrete carcinogenic secretions accumulated in the prostate acini, thus reducing the risk of prostate cancer.

Another hypothesis suggests that depression and inhibition of sexual activity are factors that increase prostate cancer risk, so low ejaculation is discouraged. As early as 2003, an Australian study showed that more frequent ejaculation reduces the incidence of prostate cancer.

Jennifer R. Rider and her team from the Epidemiology Department of the Harvard School of Public Health, explored the relationship between sexual activity and prostate cancer, and published in European Urology in 2016 the title “E jaculation Frequency and Risk of Research paper on Prostate Cancer: Updated Results with an Additional Decade of Follow-up .

In this study, the researchers analyzed data from about 32,000 men over 18 years and found that more than 21 ejaculations per month reduced the incidence of prostate cancer.

They followed men who came for 10 years and integrated their follow-up records with the initial pathological analysis to comprehensively assess the association between ejaculation frequency and PCa.

During follow-up data collection, PCa patients recorded their monthly frequency of ejaculation. The study, which involved 31,925 men, began collecting data in 1992 and continued through 2010. The study assessed average monthly ejaculation frequency in men by three time periods: 20-29 years, 40-49 years, and the year prior to participation in the follow-up questionnaire.

The data showed that in the 20-29 age group, the hazard ratio for the incidence of PCa was 0.81 for ≥21 ejaculates compared with 4-7 ejaculations per month; and for the 40-49 age group, the hazard ratio was 0.78.

That is, in adult men, higher ejaculation frequency was less likely to be later diagnosed with prostate cancer than lower ejaculation frequency.

This study draws on a wealth of data to demonstrate that active sexual activity (more frequent ejaculation) in adult men may reduce the risk of prostate cancer (PCa).

In addition, industry-related data show that 38% of married people aged 60 or over in the United States engage in sexual activity 1-4 times a month, and 14% of them say they engage in sexual activity at least 5 times a month.

Although libido declines with age, sexual activity is still common among men in their 70s, 80s, and even 90s. Given that sexual activity is still common in older men, but older men are at high risk for prostate cancer, the idea that frequent sexual activity increases prostate cancer may be influenced by the fact that older men have a higher incidence of prostate cancer.

Studies on the association of sexual activity and prostate cancer are mostly limited to controlled studies of previously diagnosed prostate cancer cases, which may be prone to methodological bias because information on sexual activity prior to a diagnosis of prostate cancer was collected at the time of cancer diagnosis.

Collected by patients’ self-recall after diagnosis. Sexual function may be diminished after prostate cancer diagnosis and treatment, and in patients diagnosed with prostate cancer and undergoing treatment, there may be false recalls and representations of past actual frequency of sexual activity.

In addition, men with higher ejaculation frequency may have more accurate recall of past ejaculation frequency levels than men with lower ejaculation frequency.

Another point is that the studies described above assessed ejaculation frequency in adulthood, not adolescence.

Since the differentiation of prostate epithelial cells occurs during the critical period of puberty, puberty may have an etiological significance for the development of prostate cancer.

If ejaculation frequency in adolescence is important for prostate cancer development, data on ejaculation frequency in adults will not allow this to be assessed.

However, there are also some related research results that show that the frequency of ejaculation in middle age and old age is also a relevant period for affecting prostate cancer.

Prostate cancer itself is a relatively slow-growing cancer, and if detected and intervened early, and the cancer cells have not spread beyond the prostate, there is a chance of good treatment.

Possibly because of organ and treatment constraints, data on sexual activity are less collected in advanced prostate cancer cases, so it is currently only possible to hypothesize that sexual activity may delay the development of early-stage prostate cancer.
