Research again yielded encouraging results. Recent studies have found a new contraceptive option to enrich the choice for couples who want to use. This time, contraception was not found for women, as has been widely available, but for men. Researchers from China stated, testosterone injections every month is a contraceptive method that is safe, effective, and trusted for men.

The study, published in the Journal of Clinical Endocrinology and Metabolism this, based on evaluation of 1045 Chinese men are healthy and fertile. "We are very satisfied with the findings of this study," said researcher Dr. Yiqun Gu, as quoted foxnews site.

Group of hormonal contraception for men, the bright Gu, offers a new and effective alternative for couples who can not or prefer not to use contraceptives that are oriented to women throughout the reproductive period.

The man who acted as participants in the study had an age range between 20 and 45 years. They at least have had one child, 2 years before the study began. While their female partner aged between 18 and 38 years old and all had normal levels of fertility.

The men received testosterone injections every month for 30 months. During the first 6 months, participants were checked to ensure that the injection has been effective to eliminate or significantly reduce the number of sperm in their semen. Furthermore, only participants with little or no sperm are allowed to continue the study for 24 months in the future.

During the follow-up occurred nine pregnancies. That is, the light Gu, contraceptive failure rate is 1 / 100 men. This figure, added Gu, very good compared to other methods of contraception, including condoms and contraceptive pills.

"During the study period there were no serious side effects. In addition, after stopping the injections, the ability to produce sperm in men return to normalcy," said Gu.

However, light Gu, further study is needed to ensure safety in the long term. In addition, he explained, needed refining to ensure that these men did not produce sperm during the use of contraception.
