Doctors in Canada have begun a new chapter in medical history, delivering the first in a wave of babies through a technique that some experts think can dramatically improve the success rate of in vitro fertilization (IVF).
Now 22 days old, Zain Rajani was born through a new method that relies on the discovery that women have, in their own ovaries, a possible solution to infertility caused by poor egg quality. Pristine stem cells of healthy, yet-to-be developed eggs that can help make a woman’s older eggs act young again. Unlike other kinds of stem cells, which have the ability to develop into any kind of cell in the body, including cancerous ones, these precursor cells can only form eggs.
In May 2014, Zain’s mother, Natasha Rajani, now 34, had a small sliver of her ovarian tissue removed in a quick laparoscopic procedure at First Steps Fertility in Toronto, Canada, where she lives. Scientists from OvaScience, the fertility company that is providing Augment, then identified and removed the egg stem cells and purified them to extract their mitochondria.
It’s not currently available in the U.S., since the Food and Drug Administration (FDA) considers the process of introducing mitochondria a form of gene therapy, which it regulates. So far, some three dozen women in four countries have tried the technique, and eight are currently pregnant. All of the women have had at least one unsuccessful cycle of IVF; some have had as many as seven.
