Why are there no birth control pills for men?

In general, there are birth control pills for men. And this is what I found from the lips of professionals.

The drug containing "cyproterone acetate"

Continuous use of the drug leads to temporary sterilization and a decrease in sperm count. After stopping taking the pills, sperm volumes are restored, but it is not yet clear how long a man will be able to fertilize.

Tablets containing "estrogen and androgen"

Such pills cause an increase in sex drive and at the same time reduce sperm quality. You can use it for 1 month, and then take a break for 3-4 months. If the drug is used for too long, side effects may occur: mental disorders, decreased tone and interest in life.

And there is even a male spiral

So far, a little-known method of male contraception. The male coil, similar to a miniature umbrella, is inserted through the head of the penis into the scrotum. At the end of the coil is a spermicidal gel.

Because men cannot get pregnant. All processes take place outside the body. And as for the creation of sperm, the process is very subtle and any intervention is fraught with complications.

Because men do not have a natural mechanism to temporarily turn off fertility, but women do. So women just need to start the natural mechanism that turns on during pregnancy, this is done easily.

But, now several drugs are being tested that reversibly suppress male fertility. One of them, for example, inhibits protein synthesis, which is needed for the formation of sperm. But we are unlikely to see them on the market in the next 10 years, because safety is important here like nowhere else.
