A recent review found that men who had more frequent penile-vaginal intercourse (PVI) had less risk of developing prostate cancer.
One study found that men who averaged having 4.6 to 7 ejaculations a week were 36 percent less likely to receive a prostate cancer diagnosis before the age of 70. This is in comparison to men who reported ejaculating 2.3 or fewer times a week on average.
For men, sex may even affect your mortality. One study that had a 10 year follow-up reported that men who had frequent orgasms (defined as two or more a week) had a 50 percent lower mortality risk than those who had sex less often.
Although results are conflicting, the quality and health of your sperm may increase with increased sexual activity, as some research suggests.
Having an orgasm increases blood flow and releases natural pain-relieving chemicals.
Sexual activity in women can:
- improve bladder control
- reduce incontinence
- relieve menstrual and premenstrual cramps
- improve fertility
- build stronger pelvic muscles
- help produce more vaginal lubrication
potentially protect you against endometriosis, or the growing of tissue outside your uterus
The act of sex can help strengthen your pelvic floor. A strengthened pelvic floor can also offer benefits like less pain during sex and reduced chance of a vaginal prolapse. One study shows that PVI can result in reflexive vaginal contractions caused by penile thrusting.
Women who continue to be sexually active after menopause are less likely to have significant vaginal atrophy, or the thinning of vaginal walls. Vaginal atrophy can cause pain during sex and urinary symptoms.
