You can control your fertility by toggling the switch on and off. A safety pin prevents accidentally opening it.

The switch was invented by Clemens Bimek in the last 20 years and he is already wearing his invention for several years. He is now collecting money for the clinical study. It has the potential to replace the pill without any sideeffects and gives men an alternative in their choice of contraception.

edit: any idea in which subreddits I could also post this?

Male Contraceptive Initiative is creating an audio series on why there aren't more male options. They're detailing the men and the motivations at the same time as giving updates on where specific research projects like vas-occlusives, on-demand pills, and current hormonal contraceptive trials are.

If you're interested in sharing your thoughts, comment here, or you can email intended@malecontraceptive.org. If you'd like to include a 30-second voice memo from your phone with your thoughts, it may make it into the final show.

Its frustrating to read such utter crap in what I thought was a respectable broad sheet. I don't understand how some women just don't see that men want to be full in control of their fertility in the same way that women are. If they do accept that men want better methods of contraception they often say that they couldn't trust a man to use it, well don't! What's wrong with each of the sexes using their own contraception, each having control of their fertility.

It just pisses me right off 😡

I'm reading about the subject and it seems that there issues around the substance are more political than scientific...

it's been concluded that gossypol can render about 25% of the men using infertile , but I feel that there are plenty of men who would find it acceptable (at least over children and surgery) and the possible side-effects such as potassium deficiency and the (yet to be confirmed) increased risk of cancer are on par with many commercially available female contraceptives.

I mean personally I would find the risk of infertility and potassium deficiency acceptable, I would not use it until more research is done on the cancer claims...

Hi everyone,

We recently made headlines again for our work on hormonal male contraception. We were here about a year ago to talk about our work then; this new work is a continuation of our series of studies. Our team will be doing a follow up AMA on r/IAMA Saturday 3/30 at 9am PST (12pm EST). If you have any questions feel free to save them up or message here and we will respond on Saturday!

Edit: We are live now! https://old.reddit.com/r/IAmA/comments/b7cqwe/we_are_doctors_developing_hormonal_male/

It seems to me that the easiest methods that an individual can experiment with are the heat based methods, external wet heat, ultrasound, keeping the testicles in the inguinal canals etc.

Has anyone on here experimented with any of these? Have you found ways to make things easier/more convenient?

It would be good to hear some success stories, though I understand these would not be under controllable scientific conditions.

Heat does sound incredibly plausible as the whole reason for testicles being in a scrotum is to keep them cool enough for spermatogenesis.

The lack of options for guys is very frustrating so I started trying to use some heat methods of reducing sperm count.

I started using those heat pads that react with air when you open the packet. These were uncomfortable as the pads are a little bulky and corners can poke into sensitive skin of the inner thigh.

Abandoning heating pads I thought I'd try popping the plums into the inguinal canals. This was a little more acceptable but retaining the jewels in position was not the easiest. The first methods I tried involved elastic type bands to stop the boys from popping back into the empty scrotum. Over the course of the day pressure from the elastic/rubber would cause some discomfort.

I've now moved on to using a large steel cock ring, the type that is designed to be worn round the base of the cock and balls. With the ring around my cock I pop the twins up into the inguinals and pull the empty scrotum through the ring. This method is the most comfortable, though having my plums tucked up all day is going to take a bit of getting used too.

I guess I'd like to know if anyone else has used a similar method with success? I've read a couple of accounts online that indicate it works. In one worrying tale the chap developed testicular cancer and attributed this to his practice of keeping his balls in his inguinal canals.

Have any of you been using a similar method for any length of time, with or without incident?

As a secondary measure to using a condom how effective would it be to use a temp adjustable heat plate (dials to specific temperature and hovers within .5 degrees F) to heat water up to a temperature of 105° F and dipping the testicles into that bath? This could of course be handled with using a hottub if available.

For controls, the dipping would be at 6p daily for 10 mins with sex happening as late as 11p.

The theory I'm going on with this question is that male testicles are housed outside the body to avoid the high internal body temperature in order for the sperm to thrive. If introduced to enough heat for long enough much of the sperm would fail to function and the next functional set of sperm would be created slowly over time. I'm imagining prior to bath there's 75% functional sperm (wild guess, I have no idea of viability of sperm in general) and immediately post bath there would be approaching 0%, each hour after that would have a new arrival rate (I assume sperm is developed continually) of 5% would return meaning if having sex at 11p and the condom broke then there'd be a better than 1/4 chance (5% * 5hrs = 25%) instead of a 3/4 chance (that your sperm would inseminate, not including the female's fertility).

What do we think of the hot bath idea? Entertainable, dumb because of some kind of flaw of logic or assumption? Let me know!

Hi everyone, Recently our research reached the front page of Reddit (link at https://www.reddit.com/r/news/comments/85ceww/male_contraceptive_pill_is_safe_to_use_and_does/). There were a lot of good questions, and Dr. Nguyen and I (Dr. Yuen), along with the principal investigator of our site, wanted to offer the opportunity for people to ask questions about the research, the drug, whether we like horses or ducks (?), and anything else people might want to know. We may not know the answers but we promise to respond to the best of our ability. We're not fully sure how this works, and we've never done this before, so bear with us. Our AMA will be in r/IAMA at 1pm-5pm PST (4pm-8pm EST) on Sat 6/16/18.

Have you ever wished for more male contraceptive options so that you wouldn't feel trapped in an unwanted pregnancy and then subsequent child support? I'm a journalist working on a story about male contraception and interested in hearing your thoughts about this.

What do you guys think about this? How does it not make sense?

I've been buying Justicia gendarussa powder from Mars Herbal LLC (puregandarussa.com) one kilogram at a time, but their website stopped working, and I suspect that it's not coming back up. Does anyone know of another reliable source?

Edit: nevermind, they're back up.

I had a lot of difficulty finding much information on it. Here is the best link I could find: http://www.newmalecontraception.org/ultrasound/

Ultrasound therapy machines are relatively cheap at around $100.: https://www.activeforever.com/acclaim-us-pro-2000-ultrasound-new-model

But its hard to find even anecdotal evidence of men who have experimented with this.

Out of these two surgeries, which one would be better for sterilization purposes: An orchiectomy or a removal of the entire epididymis plus a removal of the entire vas deferens?

(For the record, regular vasectomy certainly isn't good enough due to the fact that it can and sometimes does fail.)

Anyway, any thoughts on this?

I've been using gandarusa for 69 days as birth control, and before I rely on it, I'd like to make sure it's working. From what I can tell, I need to get an acrosome reaction test for that.

I emailed a few fertility clinics in my area, and most had some sort of sperm testing, but none of them offered an acrosome reaction test. My question is: if fertility clinics can't do acrosome reaction tests, what kinds of places can?

Completely serious question, for the record.

There is a male birth control pill that is already available on the market, but for some reasons, nobody seems to know it. It is almost 100% effective (much better than the female pill) and has no side effects. Phase III studies has been done with 99.96% success rate.

Will men in general use it?
