They are hard and can be imperfect. More importantly, you cannot have a good relationship founded on this kind of thinking: > People often lie and act irrationally. If that is your fundamental truth in interacting with your partner(s), your relationships will never really get anywhere. It is just not good advice to tell people to do so, unless you want them to never create meaningful connections with their partners.

My experiences with relationships are overwhelmingly positive. However, there's always a non-zero risk that such a maneuver can happen. I've seen it happen, many times. Even in otherwise happy couples. Are you willing to bet your future on it?

Your partner can also kill you in your sleep, life is never a guarantee

I see a couple of acceptance problems with the device. First, men a notoriously squeamish when it comes to their testicles. "Heating" without telling the temperature won't fly with many. I guess it doesn't have to be hot as it probably only needs to be warm enough to relax the cremaster muscles. If it has to be uncomfortably hot, I see little chance in the market. Second, I'd expect the ultrasound to hurt. The epidid…

4th, there's no data about return of fertility in humans after longterm use and if it raises birth defects.

And 5th, I have no idea how long sperm remains viable in the prostate, but I imagine that you would have to ultrasound your balls regularly or end up with live swimmers in a very unpredictable way.

I'd imagine you'd destroy them and maybe their precursors, then have protected sex for 2-3 times to get rid of the viable sperm and only after that end up with 1-2 weeks of infertility.

Why is it an important problem? We have hormonal and non-hormonal UIDs, many different types of pills, rings, and not to mention _condoms_ which actually prevents STDs. I don't have a problem with other guys heating their balls up, but where is the important problem?

Power and control. Females have a wide range of birth control options, all highly effective. However, they are all entirely under the woman's control. They can stop birth control without the man even knowing about it. This isn't some conspiracy theory, either. Women do show up to gynecologists to ask them to remove their IUDs with the explicit intent to have a child regardless of their partner's wishes. This is not c…

Men also have a second option that preserves power and control: Just avoid penile-vaginal sex until pregnancy is desired. I.e., say "no".

I'd love to have effective male contraception. But the previous work on this doesn't make it look like it's the answer: https://www.parsemus.org/humanhealth/ultrasound-male-contrac... See the section "Effective contraception in humans remains elusive"

DMAU as a pill or injection appears to be very effective. Studies are still ongoing. It’s been studied for a long time, and finally it seems there’s an appetite from men widespread enough to make it feasible commercially. https://endocrinenews.endocrine.org/one-step-closer-is-male-... I’ve done two drug trials with this stuff and it’s pretty cool. It appears to make men totally infertile while they’re on the drug, wi…

That sounds amazing. It will come to late for me, but I wish it had been available when I was younger.

The links to data in other comments suggests a treatment would take about 2 weeks to become effective (rid the system of existing viable sperm), then last approximately 6 months.

Although, if you look at the graphs/numbers it seems there still are a small number of motile sperm (looks to me like approximately 50% reduction in count with 20% motility). Seems like it doesn't completely eliminate the possibility of pregnancy.

Betting your future on your partner is the whole point of having a shared household. You and I must have a significantly divergent of what a positive relationship looks like.

Yeah, sure. I want to be happy though. Why can't we have our own pill?

Somehow cold blooded murder of a defenseless person doesn't seem at all comparable to an unplanned pregnancy.

I guess. I've never had reason not to be open about these issues and it's never disrupted trust in the relationship. I've discussed these ideas with every partner I've ever had. They weren't offended, they understood. Many even had their own stories of unplanned pregnancies to share.

My girlfriend lets me give her the trimestral birth control injections.

Sure, I don't disagree. But, you know, my post contained a little bit of a payload; I wasn't saying you need to be celibate.
