Male contraceptive gel passes monkey test
An experimental new type of male contraceptive that blocks sperm flow with a gel has been successful in monkey trials.
Vasalgel acts as a physical barrier once injected into the tubes that sperm would swim down to the penis.
The company behind it says a two-year trial, published in Basic and Clinical Andrology, shows the gel works and is safe - at least in primates.
It hopes to have enough evidence to begin tests in men next few years.
If those get funding and go well - two big "ifs" - it will seek regulatory approval to make the gel more widely available to men.
