Yes, it is possible to get pregnant after menopause.
More Info: Although the completion of menopause marks the end of a woman's natural biological capabilities of becoming pregnant and giving birth, such a person if in good health can still subsequently circumvent nature's barriers. By using healthily preserved eggs or having eggs from another donor inserted into her post-menopausal system, a woman in her fifties can essentially artificially induce the scenario of being able to give birth.
Research on Post-Menopausal Pregnancies
Over the course of a ten-year University of Southern California study conducted from 1991 to 2001, 77 post-menopausal women ages 50 to 63 received eggs through in-vitro fertilization (IVF). Out of this group, 42 women gave birth to a total of 45 children, for a success rate of just fewer than 55%.
Modern Medicine Breaking Barriers
Thanks to the advances in medical care and technology, all sorts of menopausal barrier breaking are now possible. For example, in December of 2009, a 51-year-old woman in India successfully gave birth after having her own eggs re-inserted. Even though she had not at the time completely finished with the process of menopause, her healthy delivery of a child at this age was still considered something of a minor miracle, especially because women usually stop making healthy eggs after the age of 45.
One of the more surprising findings of the USC study is that age of recipients did not correlate in any substantial way to their ability to give birth from the donated eggs. In other words, should a woman choose post-menopause to try and have a baby, her success will have more to do with things like health and medical history. Though the process is expensive, it is one that until recently was completely out of reach, to anyone.
The one caveat to the landmark ten-year study is the fact that 78% of all resulting births were delivered by Caesarian methods. That is much higher than the average for this procedure among younger mothers, but also perfectly understandable given the ages of the participating women.
