Reversible male birth control injection

    The idea is to use a male birth control method which will be both easily reversible and will last at least 10 years.
    The procedure will involve the injection of a non-toxic gel above the scrotum, which then will coat the sperms' passageway (the vas deferens) and incapacitate them as they swim through.
    Unlike a traditional vasectomy, the procedure will be simple and pain free, and will be reversible with another injection to flush out the gel.
