Joiner’s testicle switch could change sex

  • January 04, 2016

It is not accurately Newton carrying an apple tumble on his head, though in terms of unsentimental focus it competence be only as useful.

It was 1998 and Clemens Bimek had only come behind from a tough day during work during his carpentry workshop.

Propping himself adult on a sofa, he put a TV on and started examination a documentary on contraception.

When a uncover got into a minute outline of how spermatazoa flows by a seminal ducts into a penis, Bimek asked himself “Why wouldn’t we only build a valve in there?”

Through chance, a carpenter’s track to work took for took him past a obvious bureau and one day he motionless to take a demeanour in, to see if his thought had already been patented.

While he found that some patents had already been done in this direction, he found a ideas too complicated.

So he set out to make his possess spermatazoa switch.

Aiming high

What he has given grown – branded a Bimek SLV – has been admitted by some urologists as revolutionary.

In a one make that has so distant been conducted – on Bimek himself – medical tests have proven that a switch is effective during slicing of a supply of spermatazoa to a penis.

It has a good advantage over vasectomies in that it is flexible, urologist Hartwig Bauer told Der Spiegel.

“A third of all patients would like to have such operations topsy-turvy during a after date. But it doesn’t always work,” Bauer said.

The “gummy bear-sized” valve is placed into a seminal ducts in a elementary operation and can afterwards be switched off or on by a owners depending on his needs.

The operation to have a device – that is 1.8 cm prolonged and weighs 2 grams – ingrained would take around half an hour. And, once in, a device stays in operative condition for a rest of your life, a association behind a plan claims.

The advantages of a device are transparent – women would no longer need to bear a weight of holding contraception – and hormone altering pills would turn a thing of a past.

Sticky business

But some urologists sojourn sceptical.

Wolfgang Bühmann, orator for a Society of German Urologists, told Spiegel that a valve could have disastrous side effects.

“I trust that a implantation of this valve could lead to injure hankie building adult in a seminal ducts,” a alloy said, warning that this could stop spermatazoa travelling by a tubes.

The dilettante serve worries that spermatazoa could hang to a valve that could burden adult a switch resource over time.

What is certain is that there is still a prolonged approach to go before a valve will be accessible to a ubiquitous public.

First tests on a product are set to start early this year, with a valve being ingrained into 25 men.

“Other implants done of this element have already been used in other regions of a physique but complications. The doubt is either there will be problems when it is ingrained in this area,” Anneke Loos, conduct of a  test centre for medical products in Hanover said.

To benefit a required acceptance for his product Bimek is now seeking investment to a balance of €5 million, including by a crowdfunding campaign.

All this could take time, definition that during a beginning a Bimek SLV will be accessible to a open in 2018.
