Male contraceptive gel injection
18 March, 2013
There is a new contraceptive method being developed for men ("RISUG" or "Vasalgel"), where a gel is injected into the vas deferens, partially blocking it and disabling any sperm cells that get through. The method works for at least ten years, but is reversible. Assuming a couple has a heter to use birth control, I am wondering if this method would be halachically acceptable, if proven safe and very easily reversible.
This is intended as a question for Rav Henkin. Thanks so much.
There is a distinct commandment, based on Leviticus 22:24, forbidding sterilization of animals and people. This is considered a Torah commandment for men and a rabbinic decree for women.
The contraceptive method you suggest, although reversible, remains efficacious for years. It would be prohibited as a type of male sterilization, much like the "kos shel ikarin" prohibited in Shulhan Arukh Even Haezer 5:12. It is possible that in some unique cases it would be permitted for use, but not as a first resort.
