A Park Avenue fertility doctor has broken the age barrier for women longing to be moms.

Dr. John Zhang says a 49-year-old patient at his New Hope Fertility Center gave birth this month to a baby conceived with her own egg frozen at age 48 -- the oldest on record.

She's beautiful and healthy, the jubilant mom e-mailed friends after delivering her long-awaited daughter. She's definitely the love of our lives!

The infant might have made history in the world of in-vitro fertilization, which kicked off in 1978 with baby Louise Brown.

To the best of my knowledge, the oldest woman who has gotten pregnant from IVF with her own egg is 45, said Dr. Richard Paulson, a professor in the Division of Reproductive Endocrinology and Infertility at the University of Southern California, and a pioneer in the use of donor eggs.

Zhang, who opened his Upper East Side clinic in 2004, each year treats 60 to 80 women over 45 who want babies with their own eggs.

Five to eight give birth each year, he said.

He offers donor eggs as the oldest patient had twins at 52 from donor eggs.

-- In 1996, Dr. Richard Paulson assisted a 63-year-old woman to conceive using in vitro fertilization with a donor egg, and she became the oldest woman in the world to give birth.

This incredible example of how assisted reproductive technologies, or ART, can change the course of nature, raises tough biological, emotional, and ethical issues.

Rewinding Your Biological Clock is a unique exploration of each of these issues, especially the how-to of peri- and post-menopausal pregnancy.

Written by a leading fertility specialist and a health educator, this original and daring book rethinks society's most fundamental beliefs about motherhood, aging, and life itself.

About Catherine: I am mom to three grown sons, two grandchildren and two rescue dogs. After years of raising my boys as a single mom, I remarried a wonderful man who had never had a child of his own. Unexpectedly, I found myself pregnant at 49!
Sadly we lost our precious baby at 8 weeks, and decided to try again. Five more losses, turned down for donor egg, foster care and adoption due to my age and losses - we have accepted there will be no more babies in our house.
