Healthy Life: Contraception Options for Men

  • Photo
MALE CONTRACEPTION OF THE PAST: In the past, the typical male contraceptives included chemicals extracted from plants, as well as using heat to suppress spermatogenesis (the process of sperm cell development). These plant chemicals include Neem tree oil, papaya seeds, hemp seeds, and Gossyplium extracted from the cotton plant. These chemicals prevent sperm from fertilizing an egg by interfering with sperm concentration, motility and viability. (Source:

"THE PILL" FOR MEN: The "Bright" Pill, although still a molecule undergoing research, is a form of oral contraception for men used to inhibit sperm genesis. This pill would inhibit the synthesis of certain proteins in sperm development and would be able to stay inside the sperm when it gets ejected into the female reproductive tract. So far, it has only been proven to disturb sperm motility in experimental lab rats. (Source:
HIGH HOPES FOR RISUG: RISUG stands for "Reversible Inhibition of Sperm Under Guidance." The drug both partially blocks the vas deferens and damages sperm cells that pass through it. Because of the electrostatic force created by this electrolytic substance, the sperm that are able to pass through have broken cell membranes, leaving the gametes incapable of attaching to an egg cell. RISUG is in Phase II trials in India and in February 2010 it was approved for trials in the United States. 60 mg has been deemed the therapeutic dose for injection, and no pregnancies have been reported in 1-3 years of study.

WILL ULTRASOUND BE ULTRA EFFECTIVE? When ultrasound waves pass through an aqueous medium into the testes, they heat the testes and create an ionic exchange between the seminiferous tubules and the rest of the testes. This combined effect creates an unfavorable environment for sperm and the effect lasts for about 6 months until the human recovers. The process is painless and takes around 10-15 minutes, and it has been shown to be effective in dogs, cats, and monkeys, and humans in clinical trials. The major concern is that every patient has a different recovery period and there is no evidence that recovery will continue to occur after extended treatment. (Source:
