Infertile? You Might Still Get Pregant Naturally
a blog by Claire, May 4, 2012
You just never know — a new study finds that being labeled "infertile" does not necessarily mean you will never have a baby naturally. French researchers published in the Fertility and Sterility that helps clarify those anecdotes about people having a successful or failed in vitro fertilization (IVF) and then going on to have a baby naturally.
Penelope Troude, M.D., with the French national medical research institute (INSERM) and her team of researchers wanted to get a better idea of how often people going through IVF actually end of up getting pregnant without assistance — live births following spontaneous pregnancy or BSPs. The team collected information on 2,134 couples who had started fertility treatment in France from 2000 to 2002. Eight to 10 years later, the couples responded to a survey about whether they had had a child on their own following fertility treatment.
The researchers found:
- About 1,300 of the couples had a baby through IVF.
- Among the parents who'd had a baby via IVF, 17 percent later had another child without assistance.
- Among couples who had failed IVF, 24 percent went on to later have a child without assistance.
- In both groups of women, the probability of having a child without assistance was higher among younger women and those whose cause of infertility was unexplained.
- Among women younger than 35 with unexplained infertility, 45 percent became pregnant after failing to have a baby through IVF.
Keep in mind that the couples still experienced a low birth rate overall. The researchers wrote in the paper:
"Our results should give hope to couples who have been unsuccessfully treated by IVF, especially young couples with unexplained infertility. Nonetheless, it should be remembered that the BSP rates are cumulative rates observed over a long period of time and that these couples have a very low monthly probability of conceiving."
