New male contraception

Many users of contraception ask for an alternative to existing forms e.g. condom, birth control pills or sterilisation by surgery. VasDeBlock (under development) is the alternative male contraception method that is non-surgical, hormone-free, easily reversible and far more practical than condoms.

VasDeBlock devices inserted to vasa deferentia vas


The new male contraception method is an alternative to traditional sterilisation by surgery which 2-5 million men (procedure called vasectomy) and 6-10 million women (procedure called tubal ligation) in developed regions undergo yearly. 

The solution will be marketed as a medical device and offers the big advantage that fertility may quite easily be restablished. 
The solution has patent pending.
