A remarkable 20 years after freezing her ovary, an Israeli woman defrosted part of it, reversed her menopause, got pregnant without IVF, and has now given birth to a healthy baby girl.

“She conceived spontaneously at age 45, and she now has a baby girl thanks to pieces of her ovary that were in liquid nitrogen for two decades,” her gynecologist, Prof.

The pieces of ovary we transplanted were no longer working — she had passed menopause.

Revel said that it “reversed her menopause,” explaining: “When production of estrogen ceases, symptoms of menopause set in, but if healthy ovaries are returned, it restarts the woman’s period, makes her fertile again and triggers the production of estrogen.” The doctor predicted that Tzvia now won’t enter menopause for several years — for as long as the newly transplanted ovary pieces remain active.

But he believes it could be seen as a legitimate way for healthy women to extend their childbearing years.
