The idea of male contraception seems novel,
But this is not the case.
Since the birth of male contraceptives,
It's been more than half a century...
Back in 1950,
There is a doctor in Switzerland, Martho Voegeli,
A sauna contraceptive trial is being done.
He sat the men in a bucket filled with hot water at 46 degrees Celsius,
Sitz bath for 45 minutes a day,
It lasts 3 weeks.
The results show that
Sauna contraceptive tests can be effective in killing
Sperm after at least 6 months.
The sperm undergo the most bizarre torture - "heat death".
At this time, in the Oregon State Prison in the United States,
A secret human trial is underway,
This drug is called WIN 18446,
The sperm count of the prisoners who took it was greatly reduced,
After drinking,
The prisoners became moribund and almost flew into the sky.
But for sperm,
It seems that "being poisoned" is more painful than "being heated".
Later, scientists invented a contraceptive underwear,
It doesn't look much different from modern panties.
But you will find that
This panty, it's really tight.
Tight to the point that the eggs can't breathe freely,
Tight to the egg eggs sweating,
It seems to have been tested again by the "sauna".
Believe it or not,
Mother Nature, while creating and nurturing us,
It also gave us some natural contraceptives.
In India,
People inject a certain leaf extract into a male brother,
It can play a role similar to vasectomy.
Having said that,
But the words "injection" and "brother" are put together,
The men looked,
It is inevitable that the lower body will be painful...
Don't like leaves?
Don't like injections?
Papaya sounds better.
Studies have found that a large number of papaya seeds are consumed,
Male rats can be 100% contraceptive successful.
What's even more surprising is that
The male rats also lost weight.
oh? What more can be achieved unexpectedly?
We come back to the modern era again.
The most widely known is "vasectomy",
Outpatient can be operated,
The duration of the operation should not exceed 15 minutes.
But as for whether it is painful or not,
This is an unanswerable question.
Ligation can lock sperm in the testicles forever,
It is impossible to meet the Egg Queqiao.
however
The most fatal drawback of this approach is that it is irreversible.
The Dinks regret it and it doesn't work,
The knot that was tied could no longer be untied.
An Indian scientist, Sujoy Guha, has devoted his life to it.
A reversible procedure, RISUG, was studied.
The first half of this surgery is exactly the same as "ligation",
Let's find out the vas deferens first,
The difference is that,
RISUG is no longer knotted,
Instead, a chemical is covered in the vas deferens.
The principle is said to be to destroy the membrane of the sperm,
The sperm can no longer swim...
This provides the Dinks with the world's wonderful regret medicine.
The method of re-passing is also very simple,
Vibration, current and rectal massage.
emmm......
Sounds a little weird?
Fear of surgery,
There are also two newly studied drugs -
Dimethylandrosterone undecanoate (DMAU)[1],
11-β-methyl-19-nortestosterone dodecyl carbonate (11-β-MNTDC).
Good long name.
They work in a similar way.
These are all signals of sperm maturation that are transmitted by the brain to the testicles.
And that means,
It will interfere with hormone secretion,
This may result in erectile dysfunction and low libido.
Yes, can this not be successful in contraception?
There is also one of the craziest ways.
Scientists have developed a small pill,
can physically prevent male ejaculation,
But it has no effect on the feeling of male orgasm,
Hence the name – dry orgasm.
Undoubtedly, this small pill has a certain attraction for men,
Because, it can effectively avoid "a mess".
And does this mean that men can also pretend to have orgasms?
And finally,
Friendly Reminder:
Please do not easily try the above mentioned,
Contraceptive methods from ancient wisdom.
We can't guarantee that you won't be "happy to be a daddy".
Of course, after reading this article,
You can also think backwards...
If you really want to get pregnant,
Don't let your man go to the sauna,
Let's throw away the tight little leg pants at home.
postscript:
According to statistics, in the 2015 United Nations report on the use of contraceptives in the world, the main contraceptive method for married or cohabiting women was taking the pill and using other female contraceptives (such as birth control rings), and only 8% of them relied on men wearing condoms.
The data tell us that the burden of contraception is mostly borne by women, and the harm of contraceptive failure is mostly borne by women.
At present, the main methods of contraception in men are condoms and vasectomy. Due to the "boot tickling" defect of condoms and the irreversibility of ligation, it is not well received by most men [2].
Although studies have shown that there is no necessary link between male contraceptive use and sexual function, most men still reject male contraceptives, and it is not known whether small pills carry the pot of "more than enough and insufficient strength".
The perfect male contraceptive drug with few side effects and effectiveness is still under development, and it is estimated that it will take 10 to 20 years. Large-scale clinical trials and observations are also needed before any drug can be put on the market.
The human contraceptive plan is not yet completed...
