University of Edinburgh started its testing of the hormonal male contraception. This is the second phase of the study, which is carried under the guidance of WHO. Previous tests have already confirmed effectiveness and safety of the new drug.
This experiment, which will last one year, will be working with 20 couples. Male contraception has to be reliable (the developers aim to surpass condoms in terms of safety) and easy to use, for instance the test drug will be injected once every two months. Another important aspect of this new drug is reversibility of its effect.
Male contraceptive contains combination of two hormones: testosterone and progesterone. The drug reduces sperm count to the lowest level, at which fertilization is impossible.
