Your Best Chance to Become Pregnant is IVF Over 40
Women today are delaying childbearing for a number of reasons. These reasons can include education, career goals, the desire to be in a stable relationship. It may also be a desire of financial security. Since 40-year-old women today look and feel like they’re 30, they expect their bodies to act like 30. Unfortunately, time is not working in their favor, and their fertility is decreasing as they age. IVF procedure with donor eggs has become the best option for successful pregnancy in woman over 40.
Fertility in women starts a gradual decline around age 30, which becomes a steeper decline after age 35. By age 40, the chances of conceiving, without assistance, are about 5% per menstrual cycle. Compare that to 20% for women under 30. Part of the reason for this is that Your Best Chance to Become Pregnant Over 40 is Through IVF. After 40, over half of a woman’s remaining eggs are chromosomally abnormal. These eggs cannot create a viable embryo, one that has a good chance of implanting.
For woman over 40 the chance of conceiving unassisted is low and the time left in their reproductive life is limited as well. So, many women over 40 find it makes the most sense to turn to IVF as soon as possible. Most fertility centers start patients off with less invasive strategies like ovulation stimulation medication with IUI. They then move up to IVF if that isn’t successful. Each intervention in the system is generally tried twice before moving on to the next strategy. For women over 40, this is using up valuable time and ovarian reserves. That is why many of the best IVF clinics for over 40 believe the most prudent step is to move these women straight to IVF.
