nothing completly prevents pregnancy, spermicide doesnt also kill sperm, just remember there at 5millions little sperms in one ejaculation, and it only takes one sperm to impregnant you.
condom's are a 99% chance of PREVENTING pregnancy, but only work efficially if put on correctly and used correctly.
You might consider a copper IUD. No hormones. If you are anemic, it is not a good choice because for that first year, bleeding is heavy.
excuse me Annoymouse88, i am currently at university on my second year studing the human antomy, sexual health a huge part of my study, also is the prevention pregnancy and sexually transmitted dieases, so before you go giving false answers, spermicide doesnt always kill 100% of the sperm cells, that are entered into the womens vagina.
I think we misread each other's comments. It sounded like you were saying that spermicide doesn't kill sperm. My point was that it does, but that it's not 100% effective (i.e., it doesn't kill all of them). That's why I recommended other methods. And as I said in my first comment, I wasn't entirely sure of what you were saying in your first comment. It would help if you clarified your language. I hate to ask this, but are you using an online translator? Or are you just typing super fast?
