Well, there's always parthenogenesis...
I don't agree. A failure of oral contraceptive is either due to user error taking it or a failure of the hormones to do their job. If you are prone to getting pregnant on the pill, than you are prone to getting pregnant on the pill. I'm not more surprised that it happened twice than I am that it happened once; and that's a statical inevitability.
I don't know why the pill fails, only that it does. When I was on it, the stats given were 98% effective, and I understand that stat has been lowered a little since. I'm not sure if that excluded improper use or not. It may mean, as you say, that hormones were involved (likely in my case) or perhaps no one informed the user that taking antibiotics renders it ineffective.
His friend's case is different. Let me exlore the two options:
1) User error. It's entirely possible that the parents did not properly use the BC methods. If so, I don't doubt that they got pregnant twice, though in this case the error is with the user; not the birth-control method. This is why patches and implants are popular. They are inherently less reliable than oral contraceptives, but they are les prone ot user-error.
I have no idea what time frame we're talking about here. Were patches and implants available? By implants, do you mean IUDs? The copper 7 was notorious for its failure due to user error.
[qutoe]2) A failure of the birth control devices. In either individual case, I would consider a given person the statistical anomoly. You are part of the 0.2% of women who will get pregnant on the pill, and though condom failure rates under proper user are <0.1%, they can occur. The chance that the same couple had a woman in the 0.2% group, and also had one of the less-than-one-in-one-thousand condom failures at the point of her fertility; and that someone familiar with the couple as a coincidence is here to tell the story is simply too much to bear. It's just improbable in the extreme.[/quote]
Am I reading this wrong? It seems you're assuming simultaneous use of the pill and condoms. I read the initial post as one failure using only the pill and one failure using a condom.
I agree if you're using both methods, and correctly, it's very unlikely to have this happen twice.
Oh darn. I think I might just have to moderate myself for being off topic.
I suppose we could move this bit to the Health & Healing area...
