The large holes in the endometrium may make it easy for an embryo to implant at first, but eventually the structure will collapse in on itself, says Brosens.However, as natural killer cells rise in number over time, eventually a woman should have very low numbers of senescent cells, minimising the effects of having relatively fewer stem cells.

Johannes Evers, a professor of obstetrics and gynecology at Maastricht University Medical Center in the Netherlands, said that couples’ behavior can explain why people whose IVF didn’t work out had a higher rate of natural pregnancies afterward.“Successful couples already had their child(ren), so they will have used contraception,” Evers, who was not involved in the study, wrote in an email to Reuters Health. You may have had one or both tubes removed, or been told that the chances of conceiving naturally are low. “We could learn how to get the ideal endometrium, or implant embryos when the endometrium is ready,” he says.What causes pregnancies to end in miscarriage?

It’s not that these women are infertile – some women who’ve had as many as 12 miscarriages in a row still go on to have a perfectly healthy baby, leaving researchers wondering what’s going on.In a healthy uterus, stem cells enable the endometrial lining to build up by about 10 millimetres over the course of 10 days, after every period.

Men and women who were younger had a better chance of having a baby naturally, as did couples whose infertility didn’t have a clear cause.For instance, among women younger than 35 with unexplained infertility, 45 percent became pregnant after failing to have a baby through IVF.Infertility can be caused by hormonal problems or low sperm count, for example, but in 12 to 13 percent of couples in the study, the cause was unknown.Troude said unexplained infertility could be a good sign for couples’ chances of having a baby, compared to those who have a clear reason for not initially getting pregnant.Evers said the findings “reassure (couples) that it is not the end not to conceive by IVF, especially not if they have unexplained infertility.”Another recent study found that among couples who hadn’t been able to get pregnant after a year or more of trying, 44 percent of those who opted against fertility treatment still ended up having a baby eventually (see Reuters Health story of February 2, 2012).Still, it would be difficult to use the new findings to determine which couples might benefit from a wait-and-see approach, and which couples should proceed with IVF, Troude said.IVF runs for about $15,000 a cycle, and may or may not be covered by insurance.Troude added that the decision is made all the more challenging given that as a woman ages, her chances of conceiving decline.Although the findings offer some hope for couples trying to have a baby, she said the long follow-up time in the study and relatively low pregnancy rates “correspond to a very low conception probability.”Evers said the numbers might also overestimate the true birth rate.That’s because only a little more than half of the couples who were invited to participate in the study actually answered the questionnaire, and “pregnant couples will have been more likely to answer than disappointed, childless couples,” Evers said.
