...egg freezing can be perfected, for example, a woman who faces the loss of her egg-bearing ovaries through radiation therapy or disease could preserve her eggs for later insemination. Or, given that aging eggs rather than aging bodies are the leading cause of female infertility, a young woman who wants a career before she starts her family--or even before she chooses a mate--could freeze her eggs in their prime, then use them later...
...Egg freezing is just one of the fertility breakthroughs that are moving through the pipeline from lab to clinic. Doctors are removing and cold-storing ovarian and testicular tissue for later reimplantation, coaxing test-tube embryos to grow stronger before they are put into the womb, even performing microscopic surgery to transfer chromosomes from old, worn-out eggs into young, robust ones. All these techniques have a single purpose: to beat the odds nature has stacked against a woman's ability to bear children...
...many existing assisted-reproduction therapies were developed overseas. The world's first in-vitro baby, Louise Brown, was born in England. The first baby born from a frozen embryo is Australian. And it was in a Belgian lab that researchers found a way to inject sperm directly into an egg cell, enabling men with insufficient, slow-moving or feeble sperm to become fathers--a powerful new technique known as intracytoplasmic sperm injection, or ICSI...
Finally, after a third failure, they tried a different approach: doctors retrieved a fresh batch of eggs, and this time they used assisted zona hatching, in which the egg's membrane, known as the zona pellucida, is chemically weakened so sperm can penetrate more easily. (Another way to do this is to drill a tiny hole in the egg; both methods are less tricky than full-fledged ICSI.) Their son, Eric Richard, was born in October...
Like most couples, the Bielickis and the Burskis didn't need the newest assisted-reproduction therapies. That's just as well: these procedures have not entered the mainstream of clinical practice. Some, including R.B.A.'s egg-freezing technique. may never do so. A second patient in the Atlanta clinic is pregnant thanks to a frozen egg; so, reportedly, are three women in Italy, and births have previously been reported in Australia, Germany and Italy. But the success rate is still very low--only two births in 23 tries in Atlanta, so far--and the technique is expensive. So R.B.A...
