A 2016 study from Harvard found that men who had at least 21 orgasms in a month were a third less likely to develop prostate cancer compared to men who only ejaculated 4 to 7 times per month (1).
This study suggests that ejaculation frequency has a strong inverse correlation with prostate cancer in men (1).
In addition to the immense pleasure that you feel during an orgasm, ejaculation has a long list of healthy side effects. Ejaculating releases endorphins, your body’s feel-good neurochemicals that can reduce feelings of anxiety and stress and improve feelings of self-worth and self-esteem (2).
Endorphins also play a role in controlling appetite and increasing immune function. Plus, if you or your partner have ever found yourself snoring minutes after sex, it will come as no surprise to you that orgasms can also help you get to sleep faster (3).
In addition to releasing chemicals like dopamine, serotonin, oxytocin and prolactin, it’s thought that ejaculation can also purge toxins, impurities and carcinogens from the prostate. By frequently getting rid of sperm that may contain DNA damage, ejaculating regularly can also improve the quality of your semen.
One study showed that after ejaculating every day for seven days, 80% of the participants had an increase in sperm quality. The results led researchers to believe that increased ejaculation can lead to an improvement in fertility (4).
Prostate cancer is one of the most common cancers for men in the U.S. In 2022, the American Cancer Society estimates that there will be about 268,490 new cases of prostate cancer and around 34,500 deaths from the disease in the U.S. alone.
To put that into perspective, approximately 1 in 8 men will be diagnosed with prostate cancer in his lifetime, and 1 in 41 men will die from prostate cancer. For reference, the average age of a man when he is first diagnosed with prostate cancer is 66.
This Harvard study was published in the journal of European Urology in 2016 and took self-reported data from over 31,000 men from 1992 to 2010.
By analyzing the monthly questionnaires that the participants provided, the researchers found that men who ejaculated more (21+ times per month) were significantly less likely to be diagnosed with prostate cancer during the study.
In full disclosure, this is not the only study that’s been done on the frequency of ejaculation and the incidence of prostate cancer. Other studies have found no links between the two, and one study even found an increase in prostate cancer linked to increased masturbation.
That being said, the Harvard ejaculation frequency study is by far the most comprehensive longitudinal study on this subject to date.
So while more research needs to be done on this subject, it's clear from what we know so far that having frequent orgasms and releasing semen on a regular basis can have mental, emotional, and physical benefits.
Prostate cancer is very common, but the 5-year relative survival rate based on men diagnosed with prostate cancer between 2010 and 2016 is close to 98%.
As with many cancers, early detection, diagnosis and treatment increases positive outcomes. Since early stages of prostate cancer often cause no symptoms, they’re usually detected by preemptive screening.
More advanced cancers can cause symptoms such as problems urinating, blood in the urine or semen, erectile dysfunction, pain in the bones, loss of bladder or bowel control and weakness or numbness in the legs or feet. If you experience any of these symptoms, it’s time to see a doctor.
If you want to be proactive and increase the number of ejaculations you have each month, we encourage you to go for it! The easiest method is masturbation. Pick a start date and see if you can masturbate 21 times in a month.
If you’re looking to make ejaculating more fun for both you and your partner, give our sexual health supplements a try. You may find that when you make sex more fun, hitting 21 orgasms per month isn't so hard after all.
