There’s a new male contraceptive? Male contraceptive methods won’t change for centuries, being condoms or vasectomy. Look at this new one!
The new breakthrough in finding a male equivalent to the pill is an injection. The shot blocks sperm from coming out of the body.
Previously, an injection of hormones appeared on trials that disrupted sperm production. But it caused side effects such as depression and muscle pain. In the tests many men left the trial of one year, reason why was it was considered a failure.
Now, non-hormonal injections, which have had a 100% success rate in monkeys, could provide another option for more for the thousands of men who do the vasectomy every year.
A new male contraceptive method
The new method works by injecting a gel into the vas deferens – the tube that carries the sperm from the testicles to the urethra – and blocks it.
In addition to being less painful than ‘scabbing’, an earlier study suggests that the gel injection is reversible, which could mean considerable savings for men who change their mind and want to reverse their vasectomy, something that may also often result failed.
Teams could test it on people early next year (2018) after trying it on 16 male rhesus monkeys that couldn’t fertilize monkeys for more than two years.
Professor Adam Balen, president of the British Fertility Society, says: “This is an interesting technique that achieves a” reversible vasectomy “by blocking the passage of spermatozoa with a substance that can later disappear.”
“If it is free of side effects, then this new approach will have the potential to be a great promise as a new male contraceptive. It is essential to know that reversibility is present regardless of the duration of use. “
Fertility expert Allan Pacey said there could be a ‘global market’ for an effective male contraceptive.
He added: “The idea of trying to replace the traditional method of vasectomy by inserting a gel into the tube that carries sperm from the testicles to the penis in ejaculation is not new.”
“However, we have not made much progress in developing the idea in recent years. So this study is a useful step in the right direction.”
Vasagel
Finding a new male contraceptive is of great importance; it would eliminate the pressure of women to prevent pregnancy. Scientists have also examined the disruption of sperm’s ability to swim and disrupt brain signals to block sperm production.
The use of a gel, with the name Vasalgel, to prevent sperm from going into the semen, appeared last year. It was successful with rabbits for 12 months.
It works similar to a vasectomy, which also blocks or cuts the vas deferens to prevent sperm from traveling. But, unlike a vasectomy, which most men have to pay privately if they want to reverse their effect, and have a success rate as low as 30 percent, the gel injection was found which was reversible in rabbits.
The latest study was made to test whether sperm blocking in rabbits, injection could prevent pregnancy.
A team from California oversees rhesus macaques that were on Vasalgel for at least one breeding season. During this 80 percent of the females housed with them normally become pregnant.
However, for an average time period of almost 1.2 years, and up to two years for some monkeys, there were no pregnancies.
This success rate is even higher than that of the pill. It offers about 99 percent effectiveness in people and animals. Clinical trials should begin in early 2018.
Side effects observed with hormonal injections, which were reporting mood and pain disorders, were not seen in monkeys. There was one case of a development of a sperm granuloma, a tumor from leakage of sperm. However, this is less likely than after a vasectomy.
Previous research has shown that most men are looking for a male contraceptive. However, many men worry about the side effects of hormonal injections.
