In terms of men's health issues, prostate cancer features are high on the agenda. This The second most commonly diagnosed cancer Among men globally – lung cancer follows closely. And it's The most common cancer in men within the UK.
Because the prostate is a reproductive organ whose primary function is to assist make semen—the fluid that carries sperm within the ejaculate—researchers have long questioned the effect of sex aspects on a person's risk of prostate cancer. Specifically, does ejaculation protect against prostate cancer risk?
Interestingly, there's some evidence to support this concept. Fresh Review A review of all relevant clinical research over the past 33 years found that seven of 11 studies reported some useful effect of ejaculation frequency on prostate cancer risk.
Although the mechanism shouldn't be fully understood, these studies fit with the concept ejaculation may reduce the concentration of poisons and crystal-like structures that may accumulate within the prostate and Can potentially cause tumors.
Ejaculation may occur. Alter the immune response By reducing inflammation inside the prostate – a known risk factor for the event of cancer – or by increasing the immune defense against tumor cells.
Alternatively, by Reducing psychological stress Ejaculation can reduce the activity of the nervous system, which then prevents some prostate cells from dividing too quickly and increases their possibilities of becoming cancerous.
Despite these proposed mechanisms, in research suggesting that ejaculation is protective, it seems that the main points matter.
Age plays its role. Sometimes the frequency of ejaculation was just protective. Age 20-29, or 30-39and sometimes Only in later life (50s and older) and really increased risk in younger life (20s).
Other times, ejaculation occurs during puberty (when the prostate continues to be developing and maturing). The biggest impact Decades in a while prostate cancer risk.
But how often? Well, in some cases fairly often.
Oh Studies from Harvard University It found that men who ejaculated 21 or more times a month had a 31 percent lower risk of prostate cancer than men who reported 4 to seven ejaculations monthly over their lifetime.
Similarly The results are from Australia Men who've a mean of 5 to seven ejaculations every week are 36 percent less more likely to be diagnosed with prostate cancer before age 70 than men who've fewer than two to a few ejaculations every week.
Other research Ejaculation frequency with greater than 4 monthly is a way more modest view to be protective in some age groups and patients.
No firm conclusions emerged.
It is difficult to attract general conclusions from this research, especially when the studies differ greatly in the best way they're conducted.
Factors equivalent to different populations of men studied, the variety of men included within the analyses, and differences in the best way ejaculation frequency is measured (whether it includes intercourse, masturbation, and nocturnal ejaculation basically) all add to the image. Can put within the cloud.
Indeed, measurement of ejaculation frequency is dependent upon self-reporting and sometimes spans a few years and a long time. It is subsequently a rough estimate and should be biased by attitudes, each personal and societal, towards sexual intercourse and masturbation, potentially resulting in over- and under-reporting.
Prostate tumor detection can also be biased by the incontrovertible fact that highly sexually energetic men delay going to the hospital or fear that cancer treatment may stop their sexual intercourse. Men with high ejaculation frequency may very well have prostate cancer, which shouldn't be reported in these studies.
It can be possible that ejaculation doesn't protect against prostate cancer and that this may occasionally be attributable to other aspects. For example, men who ejaculate more often could have a healthier lifestyle that lowers their possibilities of being diagnosed with cancer.
Decreased ejaculatory frequency is related to increased body mass index (BMI), decreased physical activity and divorce – all aspects related to poor general health which will contribute to the event of cancer.

Testosterone could also be necessary
Testosterone, the principal male sex hormone, can be a very important a part of the image.
It is well-known to extend the sex drive, so a person with low levels of testosterone may not have the identical desire for sexual intercourse that results in ejaculation as a person with high levels.
Contrary to early opinion that top levels of testosterone in men increase the danger of prostate cancer, the present approach suggests that not only does it increase the danger, however it is definitely low levels of testosterone. Increased risk. This is very true for men who've had prostate cancer. A worse disease result When their testosterone is low.
So it could be testosterone that lowers a person's risk of prostate cancer and in addition encourages him to be more sexually energetic.
Nevertheless, most studies don't measure testosterone levels and, at best, only recognize it as a possible influencing factor. A study Those who measured male sex hormones found that men who ejaculated more continuously had higher levels of testosterone. And these were the individuals who also had a lower risk of prostate cancer.
Sexual activity and ejaculation have advantages beyond the prostate, including positive effects on the guts, brain, immune system, sleep and mood. So although the connection between ejaculation frequency and prostate cancer shouldn't be fully understood and more research is required, frequent ejaculation (inside reason) definitely doesn't do any harm, probably does good, and is subsequently considered protected for men. needs to be a part of a healthy lifestyle.
