Why do not have birth control pills for men?

Surely your October 18 has passed smoothly, but do you know this is the Day . The Global Vaseline? While medicine has made great strides, it is likely that many men are still afraid of this form of reproductive health care. So, why do men not have their own birth control pills?

>>> Contraceptive pills for men

There is a little known fact: studies to invent oral contraceptives for both men and women have originated more than 50 years ago. Contraceptives for women have been successfully invented, and so far is one of the most remarkable achievements of reproductive health: according to a study conducted by CDC from 2006 to 2010, nearly 82% of women in the United States use oral contraceptives, more than any other measure.

Meanwhile, non-surgical, easy-to-use birth control measures for men have been constantly "avoiding " us for decades. Reason? First of all, large pharmaceutical companies all claim that the market for male birth control pills is . not available, and therefore refuses to invest money for research and development. Most importantly, fertility control solutions for men are facing many medical challenges.

"Can't come up"

In fact, birth control pills for men have been and will continue to be . "coming" to become a reality. This has happened over the past 50 years - from the perspective of Dr. Elaine Tyler, Professor of US Studies and History at Minnosetta. In the book America and Contraceptives: The History of the Promise, Crime and Freedom, he said:

"Contraceptives based on hormones for men have a long history, more than half a century, since we still go to find contraceptives for women. In the 1950s, researchers gave that male birth control pills are less than 5 years away from us, this claim has been repeated over the next half century until today.

But while the mechanism of action of female birth control pills has been adjusted to near perfection, a hormone-based contraceptive for men has yet to be found. For each mixture tested, there are many side effects. The most important obstacle is impotence. No man wants to take birth control pills if they make them "weak".

Dr. John Amory, Professor of Medicine at the University of Washington, explains more clearly the obstacles for male birth control pills: "Other hormone-based contraceptives work well on 80 - 90% of men. , reducing their sperm count to zero. These measures do not cause permanent effects and do not cause side effects.The problem is, these measures are not always successful, and we do not know because We do not even know that within 3 - 6 months, this method has always been successful in every patient, For this reason, it can be said that the contraceptive methods for men have progressed very well. close to the market, but not yet reached the destination ".

Thus, contraceptive solutions for men already exist. The only problem is that they are explosive "sudden" bombs: no one knows when male birth control pills will work or fail, and the consequences for their failure will be very serious.

Not only that, but other medical challenges are almost insurmountable. According to Dr. Amory, women only create one egg per month, while men create 1,000 sperms per second. While oral contraceptives for women work by deceiving the body that the woman is pregnant (by increasing hormones that are only present in the body during pregnancy), there is absolutely no male birth. any non-sperm period to "emulate".

Dr. Amory also said that the ability to block a enzyme responsible for converting vitamin A into retinoic acid (needed to produce sperm) is the way we "about 5 years".

But, history shows that no one can confirm when "5 years" will become "4 more years " or "now".

Alternatives

Thus, the solutions for producing birth control pills for men are still far away from us. However, scientists still have some other solutions.

First, we can inject gold nanoparticles into the testes, "warming" them with lasers until they are warm enough to kill the sperm without harming other cells. It sounds pretty promising, but certainly not many people dare to do so. And this measure has only been tested on . mice.

There are also many ways to prevent the processes needed to create sperm, such as the above-mentioned Vitamin A enzyme blocking action. Unlike normal hormonal processes, these measures will not cause impotence or reduced sexual desire. On the other hand, because these measures are only aimed at certain cycles, the ability to cause side effects with other cycles is very low. The problem is, as analyzed above, we will have to continue "waiting for 5 years" for a long time.

Recoverable tube ligation is invented by Sujoy Guha, India

Most recently, scientists have found recoverable vasectomy. With this method, doctors will "mount" polymer nets on the vas deferens to "break" sperm without having to stop sperm "lines" . This measure is cheap, can be removed at any time, and has been proven 100% effective in India. Unfortunately, this contraceptive method has not yet been widely adopted globally: the US health sector will wait until 2014 to begin testing.

The best solution (and the longest)

Finally, the eyebrow has only one method: "traditional" vasectomy: cutting vasectomy with an "installation" rate is extremely successful, extremely low! Doctor Akhil Das, professor of adjunct faculty of Thomas Jefferson University, said vasectomy surgery will last for 1 hour, and within 8 weeks, after successful sperm count test , the patient will never have to worry . will become a father again. But . "Connecting" is very difficult. This process is unstable, and the cost will be borne by the patient. If they are unsure, if they think about the ability to "hook up", I do not encourage vasectomy , " Dr. Das said.

But he also said his patients often "100% sure" each time to visit his office to register for vasectomy. They do not need to "hook" their two pipes.

And if they are not really sure, just wait a little longer: A "standard" male contraceptive solution is only 5 years away from us.
