Condoms are not very reliable (historically about 90% pregnancy prevention effectiveness over a year) due to issues with using them.

The other methods can fail due to misuse (missing a pill or get the timing wrong) or be removed without the partners knowledge - which does happen surprisingly often.

It's 98% for one year according to the NHS.

IUDs dont fail, and certainly a guy can miss his ball heating session or stop without the partners knowledge.

>>IUDs dont fail

They absolutely do, and it's often life threatening when it happens. It's very unlikely, but it's not absolute protection.

It does say that the baby's and the mother's health could be in danger, but where does it say it's often life threatening?

Never heard about an IUD failing at all so thanks for the link anyhow

It says that with an IUD if you get pregnant it's more likely that it will be an ectopic pregnancy, and those are by very definition extremely dangerous to the mother and treated as medical emergencies most of the time.

"It is the most common cause of death among women during the first trimester at approximately 6-13% of the total"

IUDs greatly reduce overall risk of pregnancy. The risk is not zero, though. When IUDs do fail, and they will, they increase the risk of ectopic pregnancies. The vast majority of those are located in the uterine tubes. Those are life threatening. There is no space for the fetus in the tube, it will rupture and cause severe bleeding which can and will kill the mother if left untreated. It's an important cause of acute abdomen.

Had it happen once with a partner (copper IUD, and it has been installed correctly), it was pretty terrible emotionally and physically.

The little asterisk you see on those 98% numbers is important, as it ignores the real life variables that come up. At least according to this planned parenthood link [https://www.plannedparenthood.org/learn/birth-control/condom...] found when tracking down some data (they do a lot of birth control), it’s actually even worse - 15 out of 100 couples using them consistently get pregnant every year, so 85% real world effectiveness.

Not saying either side is the only one who ever does weird things - noting that ideally, each side would be able to make a choice and have it stick, and it would require both sides consent for a child.

98% if used correctly, which they aren’t. Now I guess one could say “well then that’s a personal problem - people should just use them correctly”.

But the problem we want to solve is poor control over family planning, not blaming people for making human mistakes. We do that by developing better contraception options, for both men and women.

Assumes perfect use. The real figure is lower. Condoms simply can't compete with other contraception methods. Their main purpose is prevention of sexually transmitted diseases.
