Increased Ejaculation Is Strongly Linked to Lower Risk of Prostate Cancer

Increased Ejaculation is Strongly Linked to a Lower Risk for Prostate Cancer – Dr. David Samadi

According to a new study, increased ejaculation is strongly linked with a lower risk for prostate cancer in men. According to world renowned prostate cancer surgeon, Dr. David Samadi , “Prior research shows a link between the benefits of sex and prostate cancer. But this new study, with long term follow up, adds to the evidence that ejaculation frequency, is the key factor in reducing prostate cancer risk.”

Researchers claim that sex, or frequency of ejaculation may be a modifiable risk factor for prostate cancer, with more sex having the effect of reducing a man’s risk for prostate cancer. “Aside from the potential cancer benefits, sex also provides a number of health benefits such as a boost in your immunity, better sleep, and can even protect against heart disease” states Dr. Samadi.

The study was carried out by scientists at the Harvard Medical School and Brigham and Women Hospital. What they found was that “ejaculation frequency may be inversely related to the risk of prostate cancer, a disease for which few modifiable risk factors have been identified.” The study data tracked about 32,000 men, who were surveyed to find out the frequency of ejaculations between 1992 and 2010. Men who ejaculated 21 times or more each month were about 20 percent less likely to receive a prostate cancer diagnosis than those who only climaxed less than 10 times a month. As for how men achieved ejaculation, it is not a requirement to have a sex partner. Whether it be sexual intercourse, nocturnal emission, or masturbation, all are beneficial.

In Dr. David Samadi’s opinion, “these findings provide additional evidence of a beneficial role of more frequent ejaculation throughout adult life in the etiology of prostate cancer, particularly for low-risk disease”. It is encouraging that men with higher ejaculatory rates have been seen to have lower risk of prostate cancer long term, as there are not many modifiable risks for prostate cancer.

According to Centers for Disease Control and Prevention, prostate cancer is most common cancer among men (other than skin cancer) in the United States. According to the World Cancer Research Fund International, in 2012, there were more than 1.1 million cases of prostate cancer. This makes prostate cancer accountable for 8 percent of all new cancer cases, and 15 percent of cancers in men.

  • It is estimated that in 2016 in the United States, there will be about 180,890 new cases of prostate cancer
  • About 26,120 deaths from prostate cancer
  • About 1 in 7 men will be diagnosed with prostate cancer during his lifetime
  • About 1 in 39 men will die of prostate cancer.
  • About 6 cases in 10 are diagnosed in men aged 65 or older
  • The average age at the time of diagnosis is about 66
  • About 2.9 million men living with prostate cancer in the US today
