condom - only about 60% - 70% effective - pregnancy could still occur - and DOES
BC pill - most are ‘abortifacient’ in their effect - meaning they can cause a viable embryo to not be able to attach to the uterine wall and be expelled (still an abortion) I had a friend who got pregnant two times while on the pill!
Rhythm method - could be they already do use this, maybe not. Not extremely effective (my mom had 5 kids using this method)
Tubal ligation - risk to woman's health as a surgery. Not always 100% effective. Some see this as “playing” God with reproduction.
Vasectomy - not 100% effective either (my Dad had one and went on to father two more kids - a brother and a step-brother).
So, in other words, whatever they do, it is their decision and nobody else's.
Where did you get those statistics on condoms? Perfect use puts it at 98% effective and typical use puts it at 85%.
I was interested to see a study that said “pulling out” is almost equally effective. Obviously only where pregnancy is concerned, but not STDs.
No method is 100% effective, and she is clearly very fertile, but with some kind of BC they wouldn’t have as many children. But that is whatever, they are paying for all of it.
