There are all sorts of amazing medical achievements in the world of fertility these days -- the formerly unimaginable has become not only possible but increasingly commonplace.

A woman in Berlin who underwent fertility treatments recently delivered healthy sextuplets; a 61-year-old Japanese woman, acting as a surrogate, used an egg donated by her daughter to give birth to her own grandkid.

Now, as some women are choosing to have babies at a later age, a surgeon who practices at the Infertility Center of St. Louis says that women could give birth well into their 40s and beyond by having an ovary transplant. The first baby conceived via this procedure was born in London this week.

The 39-year-old woman who delivered was left infertile after her ovaries failed at age 15, sending her into early menopause. Dr. Sherman Silber transplanted a whole ovary from the woman's identical twin sister into the infertile woman last year, but in theory a woman could have one of her own young, healthy ovaries removed in her 20s and returned to her body years later.

The procedure doesn't involve IVF -- after the transplant, the woman would just have sex to conceive the old-fashioned way.

An ovarian transplant could also be an option for women facing cancer or other illness -- they could have an ovary removed and frozen before beginning the treatment.

What do you think about the idea of intentionally delayed motherhood? Incredible that it's a medical possibility, or playing too fast and lose with mother nature?
