According to the Daily Mail of December 4, a professor at the University of Erlanga in Indonesia has recently developed a new male contraceptive pill, which is 99% effective and has almost no side effects. This pill is extracted from an Indonesian shrub and has a contraceptive effect by affecting enzyme activity in semen.
This plant, belonging to the family Strychnidae and the genus Sparganum, has been used for contraception by the people of Papua Island for a long time. The active ingredients in this plant can destroy three key enzymes in semen, preventing them from entering the egg normally during fertilization. Professor Bambang Prajogo, who learned about the efficacy of this plant in 1985, has been researching for 30 years, working to develop male contraceptives. He extracted the active ingredients from the plant to make pills and conducted clinical trials to test the contraceptive effects of the pills.
According to Prayogo, this drug only reacts with enzymes, so it does not affect the quantity and quality of sperm. Currently, researchers have not found any significant side effects caused by the drug, and of course, compared to the various side effects caused by commonly used hormonal contraceptives for women, they can be ignored.
The Indonesian drug regulatory agency is planning to conduct larger trials to further determine the effectiveness of the drug. Pharmaceutical companies around the world have already shown great interest in the drug. Prayogo said that the drug will be available before 2016, but according to relevant regulations, it will take at least ten more years for the drug to appear in the European and American markets.
