Today’s post is by “Obi,” a Nigerian doctor conducting his field experience at Planned Parenthood as part of his MPH program. He was a general practitioner in his home country with main interest and expertise in maternal and child health.
Over the past decades the tedious, but important job of using contraception has mostly been the woman’s – from daily pills to injections to invasive surgical procedures – the burden is uneven. I come with good news!
A relatively new long acting reversible contraceptive (in the biz we call them LARCs) is currently being tested on men in India with a likely release to the general public by 2017. It was created by Professor Sujoy K. Guha from the Indian Institute of Technology with the name Reversible Inhibition of Sperm Under Guidance (RISUG). It is being spearheaded by Parsemus Foundation. Like a vasectomy, it is an outpatient procedure and needs a tiny incision in the male genital area but unlike vasectomy, it’s more easily reversed.
Here’s a brief description of how RISUG/Vasalgel works:
- a pin hole-sized incision is made at the base of the scrotum
- the physician locates and gains access to the vas deferens
- Vasalgel is injected into the vas deferens and then carefelly placed back into the scrotum
That’s it! Vasalgel is made up of two chemicals which mix when injected and thickens to make a polymer lining the vas deferens. Its specific mechanism of action is that it lines the wall of the vas deferens and lets sperm flow through it but ruptures the sperm cell membrane as they pass by. Fantastic, right?!
Vasalgel can be effective for up to ten years. When the male wants his fertility back, a solution of dimethyl sulfoxie or sodium bicarbonate (baking soda) and water is injected into the vas deferens, which flushes it out. The procedure has been proven in clinical trials to be very effective and there are some side effects like scrotal swelling and pain but those were very limited. As you know, female contraceptives also have side effects (good and bad) so you can expect the same from a male contraceptive. It is important to note that Vasalgel will NOT prevent the spread of sexually transmitted diseases.
Have you heard of this simple, yet innovative LARC procedure for men? What do you think?
