It has been shown that hormone contraceptive injection in men is safe and very effective.
According to US researchers, when the test was carried out on about 270 men, the jab effectiveness was approximately 96% with only four pregnancies among their partners.
However it was very effective, there were a relatively large number of those who used this kind of contraceptive reporting that the injection has some side effects which include mood disorders without leaving out acne.
It has been 20 years since researchers started to investigate potential for male hormone contraceptive.
The main aim for their research is to find a very effective way that can be used to suppress the production of the sperms without causing any side effect that can be unpleasant or unbearable to the user.
Since men are known to be constantly producing sperms, there is need for high level hormones that can reduce the rate of sperm production from the normal sperm count which is always over 15 million sperms per milliliter of semen to under 1 million sperms per milliliter of semen.
Performing the study
The Endocrine society had published this study in the Clinical Endocrinology and Metabolism.
The study focused on men of age 18 to 45 years old and who have been practicing monogamous marriages or relationships for a period of at least one year and whose partners had agreed to participate in the study.
At the beginning of the study, there was a need to ensure that the men involved were normal. This was done by checking their sperm count.
After that, each male participant had two hormone injections: progesterone injection and testosterone injection. They were to be injected after every eight weeks, and they had to be monitored for a period of 6 months until their sperm count reduced to bellow 1 million.
They were then requested to rely on the jab as their only form of contraceptive and take it in the same interval. This efficacy stage of the study lasted for about 1 year.
In order to determine how quick their sperm count could recover, they had to stop taking injection
