Prostate Cancer Risk and Sex

Studies have attempted to establish a relationship between sex, orgasm, vasectomy, and number of sexual partners or sexually transmitted diseases with the risk of prostate cancer. None of these studies have managed to establish a definitive relationship between any type of sexual activity or sexual operation with the development of prostate cancer. Sexual intercourse or activity does not cause prostate cancer or increase prostate cancer risk.

Prostate-specific Antigen, Sex, and Prostate Cancer
The prostate-specific antigen (PSA) test measures the amount of PSA present in the blood stream. A rising level of PSA can indicate a growth of the prostate gland which may be indicative of a prostatic tumor.  The prostate gland, however, is a sexual organ which produces fluid during sexual arousal and sexual activity. As the gland is stimulated to produce fluid, the level of PSA present in the blood stream rises. Sexual activity before taking a PSA test may result in higher levels of PSA and are in no way related to the development of prostate cancer.

Sex after Prostate Cancer Treatment
Prostate cancer therapies treat the prostate gland which is part of the male reproductive system. Treatment in this area of the body can cause both sexual and urinary complications. Sex after prostate cancer is possible, and is in fact encouraged by doctors. Sexual stimulation, both manually or by a partner, increases the flow of blood to the penis and decreases the risk of impotence after prostate cancer treatment. Sexual activity does not affect the aggressiveness of malignant prostatic tissue. After prostate cancer treatment, engaging in sex does not increase the chance of biochemical recurrence.

Other Factors
Some researchers believe that having a vasectomy causes a slight increase for the risk of prostate cancer. Other researchers have found that having a sexually transmitted disease such as chlamydia may actually decrease a man’s chances. These researchers, however, also stress that men should not attempt to contract chlamydia as a preventative method. These studies all require further testing and analysis, however, to substantiate their link to prostate cancer development.
