Pregnancy From New Technology

A woman in Japan whose periods ceased at age 25 has given birth to a healthy baby boy thanks to some new reproductive technology.

New baby born

There is a happy new mom in Japan, whose dream of having a baby came true as she gave birth to a healthy little boy via cutting-edge fertility technology called in vitro activation (IVA).


You’ve probably heard of in vitro fertilization (IVF), where mature eggs are extracted from the hopeful mom-to-be and fertilized with sperm outside the body, then reintroduced into her womb. IVA is similar, yet at the same time, totally different.

This new mom’s periods completely stopped when she was only 25 years old, and she was diagnosed with primary ovarian insufficiency (POI). Doctors removed a small part of her ovary and fragmented the tissue, which allowed it to flourish and proliferate. This tissue was then treated with medication that would encourage it to activate dormant follicles. After two days, this tissue was transplanted back into the woman and 12 others who were participating in the study.

They were then monitored with sonograms and blood tests to check hormone levels, and then they underwent a typical IVF cycle which culminated in egg retrieval (successful in five of the women), fertilization and implantation back into the womb.

Healthy baby boy

The mom featured in this study had a healthy baby at 37 weeks and 2 days, and he weighed 7 pounds, 7 ounces and had Apgar scores of 9 and 10.

Out of the original five who had successful egg retrievals, hers is the only live birth. Another patient is currently pregnant, a third’s pregnancy wasn’t able to be maintained and two others have frozen the fertilized eggs for later use.

Doctors hope that this technology will continue to develop and be useful for moms who are not only suffering from POI but women who become sterile from cancer treatment or older women who have trouble becoming pregnant.
