請依下文回答第 14 題至第 17 題The danger of delaying childbearing, of course, is that a woman who eventually wants a baby may be unable tohave one because her eggs are no longer viable. But researchers have developed a procedure that, 14 not stoppinga woman’s biological clock, can in effect act as a snooze button. Egg freezing, or “oocyte cryopreservation,” useshormones to boost a woman’s production of eggs, which are then extracted and frozen, 15 them to be thawed,fertilized, and implanted in her womb at a later date. Freezing puts the eggs in a state of 16 animation, meaningthat in theory, a woman can keep a viable store of eggs on ice long after her body’s natural supply is depleted.While egg freezing is available primarily to cancer patients facing infertility from chemotherapy and radiation, agrowing number of clinics are offering the procedure to 17 healthy women who simply want to postponechildbearing for personal reasons.
