However, the researchers also acknowledge that this method of injecting contraception has a high probability of side effects, including side effects including acne and severe emotional disturbances.
Researchers have been investigating the possibility of men receiving hormonal contraception for up to 20 years. They have been looking for an effective way to suppress sperm production without causing men to feel uncomfortable or unbearable side effects. Since men have been producing sperm, it is necessary to increase the amount of hormones to reduce the density of sperm, so that the sperm concentration is reduced from 15 million per ml to only 1 million per ml.
The researchers conducted at least one year of follow-up studies on approximately 270 male volunteers between the ages of 18 and 45 who were monogamous and their spouses were willing to participate. the study. In the initial phase, the researchers measured the number of sperm in male volunteers and ensured that they were normal reproductive workers. Every eight weeks, they receive two hormone injections, one for progesterone and one for testosterone. The researchers then tracked the number of sperm in the volunteers until the number dropped to around 1 million.
The only contraceptive method that researchers asked volunteers to take during a one-year study period was the injection of hormones. Once the injection was stopped, the researchers immediately began monitoring the rate of recovery of the sperm count. Only 8 volunteers failed to return to their original levels after one year of study. Research project leader and World Health Organization scientist Dr. Mario-Fistin said, "The study found that men who are exposed to hormonal contraception have the potential to reduce the risk of unplanned pregnancies."
The researchers stopped testing and researching new volunteers in 2011 due to concerns about the side effects of long-term injection of hormones. The long-term effects of injecting contraception may include serious emotional disorders such as depression, as well as muscle pain and hemorrhoids. These side effects occurred in a number of male volunteers who participated in the trial and resulted in 20 of them having to withdraw from the trial early.
Justin said that other researchers are implementing similar tests, using hormones, but in different amounts and in different ways, such as the form of gel. “This is an important step in finding the best way for men to receive hormonal contraception.â€
Alan Percy, a professor of male science at the University of Sheffield in the United Kingdom, said that “effective regenerative methods of contraception are definitely in demand. But so far, all relevant research and preparations are due to The reasons for this have not been commercialized. The male hormonal contraceptive method in this study is undoubtedly promising." Of course, Alan Percy is also concerned about the side effects of this approach.
