If there was a method that allowed you to avoid taking pills or wearing condoms, and only needed one injection to achieve contraceptive effect that would last for 13 years, would you take this injection? The point is that during these 13 years, if you have the need to have children, you can still restore your fertility. In short, it will not have any impact on your body.
It sounds very attractive, and many men said that they are willing to take the injection if it is true and reliable. This is actually a contraceptive method invented in India. Many netizens said Do Indians still use contraception? Then the effectiveness of this method needs to be considered... Let's not worry about whether Indians can prevent pregnancy, but technically speaking, one injection can control it for 13 years. Is this really reliable?
Contraceptive methods
Condoms were first transformed from the intestines of animals. Since then, people have gradually got rid of the laborious and ineffective contraceptive methods in the past. Take a look at the outrageous contraceptive methods that will shock your mind.
Someone invented contraceptive spray , which can be used by both men and women to prevent pregnancy by smelling it before going out. There are also flash bras . In ancient my country, silver needles were even used for contraception . Add some silver needles to the tea you usually drink...silver needles Contraception is too cruel, and the person may die before she gets pregnant. But if you look closely, most contraceptive methods from ancient times to the present are targeted at women. Why is this?
Male contraceptive pill Research is slow
Although we have now been able to make condoms as thick as only 0.01 mm, this means that the feeling when using them has tended to be similar to that of no condoms. However, it costs a lot of money to keep it at home, and there are hidden dangers if it falls off or cracks during use. Nowadays, there are endless methods of female contraception, from emergency contraceptive pill to short-acting contraceptive pill and then to the ring surgery, these are all relatively effective contraceptive methods.
However, some misconceptions or non-standard use may lead to contraceptive failure, resulting in "human life". Even though women have a variety of contraceptive methods, it has to be said that they also bring pain to their bodies. On the other hand, for men, there are currently only two methods of male contraception, one is condoms and the other is ligation. However, due to the solidification of many men's ideas, they are not willing to choose and ligation even after giving birth.
Scientists’ research on male contraceptives actually began in the last century. is a kind of hormonal contraception, which suppresses male endocrine and sperm synthesis by giving feedback to exogenous androgen . The other type is non-hormonal. This can directly affect the formation of sperm or indirectly inhibit the motility of sperm to achieve a contraceptive effect. But we already know which two angles to start from. Why has male contraceptive pills developed so slowly from the last century to the present?
The reason for the slow development of male contraceptive pills
1. The difference in quantity is too big
Women have precise ovulation cycles and only ovulate one to two eggs at a time, while men have a huge number of sperm, the time is not fixed, and the output is large. 's research on female contraceptive pills is more like setting up a guard, which would be nice if it could stop the foreign intruder, the egg, at regular times and at fixed points. For men, it's much more complicated. They have to resist the attacks of hundreds of millions of foreign invaders. Missing even one of them will run the risk of killing someone. The research and development of male contraceptive pills faces great challenges in terms of success probability.
2. Problems with the sequelae of drugs
The emergency contraceptive pills taken by women today are actually very harmful to women. Therefore, unless there is an emergency, many women will choose to take short-acting contraceptive pills that are less harmful. However, during the research on male contraceptive pills, it is necessary to ensure that men can return to normal reproductive functions within a few weeks after taking the pill. uses drugs that inhibit sperm formation, such as gossypol and , although they can achieve a contraceptive effect. But it is difficult to restore normal fertility in a short period of time. Long-term use can also cause some adverse reactions, including permanent infertility.
Sterling Pharmaceuticals also developed a male contraceptive, and even used male prisoners in prison as experimental subjects. After several tests, it was found that the contraceptive effect of this drug was very good, but suddenly one day a prisoner was urgently Seek medical attention. It turned out that he drank alcohol after taking this contraceptive product . So far, the experiment also ended in failure. Therefore, it has become a difficult problem to make a male contraceptive pill that is effective and has no side effects.
India invented the male contraceptive injection
While researchers from various countries were having a headache, India had made a breakthrough in the field of male contraceptives. In 1979, Professor Guha of India proposed to inject the gel form of a material used for sewer disinfection into the male fallopian tube to inhibit sperm. This method of contraception is called "RISUG" .
This mainly involves making a small opening in the scrotum, and then pulling out the fallopian tube for injection. Within 72 hours, a positively charged precipitation film will be formed in the lumen, thus creating an acidic environment. When the negatively charged sperm passes through, it can be damaged , mainly by reducing the pH value and charge interference for contraception without the need for invasive surgery . Therefore, the sperm will still flow out of the body, but it is difficult for the sperm to combine with the egg. This also avoids the pain caused by sperm accumulation due to ligation.
risug is currently the only male contraceptive that has completed Phase III clinical trials. The average effectiveness of is as high as 97% . And it is reversible and will not permanently affect male reproduction. When regrets it, you only need to go to the hospital to inject dimethyl sulfoxide to dissolve the risug , and the sperm will be restored to vitality.
The more developed areas adopt more modern contraceptive measures, while the less developed areas adopt traditional contraceptive methods or do not use contraception at all. According to data released by the United Nations, the contraceptive popularity rate in 2017 was 84% in China, 84% in the United Kingdom, and 85% in Canada.
But Japan is uncharacteristically different. Their contraceptive penetration rate is only 40%. This is mainly because Japanese men’s acceptance of sterilization is much lower than that of China and South Korea. The number of male sterilizations is small, and women do not take more contraceptive measures. This leads to low contraceptive popularity. Every year, the number of women who suffer physical and mental damage due to incorrect contraception and unsafe abortion is very large. Moreover, some parents who are too young cannot guide their children correctly, which has a certain negative impact on society from secondary births.
However, this contraceptive injection still needs to be tested in many countries. It is really uneasy to rely on only one report from Indians. If this safe and effective drug can pass review and be put on the market, it will be a milestone. There are definitely friends who will have the idea of "no need to wear condoms in the future", but this idea may not be too good. It is understandable for those who just need contraception to have this idea, but this pill cannot prevent sexually transmitted infections, and in terms of sexually transmitted infections, condoms still play a core role, being simple and effective.
