Doctors in Canada have delivered what is believed to be the first baby in the world born using a breakthrough in vitro fertilization (IVF) treatment that employs stem cells.

The technique, which experts say offers a dramatic improvement in IVF success rates, is expected to spawn a wave of babies born this summer, Time.com reports.

The baby, Zain Rajani, was born through a new method that relies on the discovery that pristine stem cells of healthy, yet-to-be developed eggs that can help make a woman’s older eggs as viable as those of younger women.

Unlike other kinds of stem cells, which have the ability to develop into any kind of cell in the body, these cells can only form eggs.

The technique involves adding mitochondria — the powerhouses of cells — to older eggs, which improves the odds of IVF success.

Rajani’s parents, Natasha and Omar, were the first couple to undergo the procedure and have a child.

The technique is not currently available in the U.S., since the Food and Drug Administration considers the process of introducing mitochondria a form of gene therapy, which it regulates.

The Canadian doctors who pioneered the technique said three dozen women in four countries have tried the technique, and eight are currently pregnant.
