Last year, there were 27,000 babies born to momâs over 40. The study was done to help women understand their fertility lifecycle. They still argue that the safest time to have a baby is between 20 and 35. In fact, 30% of 35 year olds need more than a year to conceive while only 5% of 25 year olds need this much time.
Generally speaking, the decade between 25 and 35 years of age would seem to be ideal. A woman's education is typically complete, she has usually gained some experience in her professional arena, and pregnancy is at its safest.ompared to in vitro fertilization without PGD, the chance for pregnancy can be increased 15 to 20 percent and the risk for miscarriage decreased by 50 percent or more. The risk for delivering a baby with Down Syndrome can almost be eliminated. Alternatively, older women can use eggs donated from a younger woman.
