It’s true that more women in their late 30s will experience difficulties conceiving and, in some cases, face more risks in pregnancy and delivery itself than women in their late 20s or early 30s. However, the decline is a continuum, not a cliff, and it looks different from one woman to the next. Female fertility is often said to “fall off a cliff” after 35, but there is growing recognition that this idea overlooks much of what we now know about how and when women become pregnant. Should women be encouraged to be pregnant in their early 20s ?
