What Is Chemical Castration?

Chemical castration is an alternative to surgical castration. Through a less invasive means, chemical castration achieves the same end as surgical castration: reducing the production of the male sex hormone testosterone.

Surgical Castration

• Surgical castration involves removal of a patient's testes, the primary source of the male hormone testosterone.

Chemical Castration

• In chemical castration, production of testosterone is suppressed by the injection of synthetic luteinizing hormone-releasing hormone agonists. According to the Mayo Clinic, these drugs interfere with messages going to the testicles.

Side Effects

• According to the University of Nebraska Medical Center, side effects of chemical castration include erectile dysfunction, hot flashes, fatigue and nausea.

Prostate Cancer Patients

• Chemical castration is sometimes used to treat prostate cancer. By suppressing production of testosterone, physicians can suppress the growth of tumors. This treatment often lasts several years.

Sex Offenders

• Chemical castration may also be helpful in the treatment of pedophiles and other sex offenders, under the theory that reduced testosterone levels lead to a reduced sex drive and decrease the likelihood of committing crimes.
