A new study has found masturbating with the intent of ejaculation daily can reduce your chance of developing prostate cancer.

The study looked at 32,000 men over 18 years, the largest scientific male ejaculation study to date.

It looked at the frequency of ejaculation of men aged 20 – 29 and 40 – 49, and discovered of the 32,00 participants – 3,839 developed prostate cancer.

Surprisingly men in the 40 – 49 age bracket who ejaculated more than 21 times a month showed a 22% lower risk of developing the disease.

It is believed that ejaculation can rid the prostate of cancer-causing chemicals, while there are also theories that if sperm is ‘cleaned out’ in this manner it can stop a build-up of old cells that could turn cancerous.

However doctors have warned that the study’s results should be interpreted with caution, speaking with the Daily Mail Dr Jennifer Rider of Harvard Medical School said:

“While this data is the most compelling to date on the potential benefit of ejaculation on prostate cancer development, this is observational data and should be interpreted somewhat cautiously.

“At the same time, given the lack of modifiable risk factors for prostate cancer, the results of this study are particularly encouraging.”

In Australia more than 3,000 men die of prostate cancer every year and around 20,000 new cases of prostate cancer are diagnosed in Australia every year.
