...while working with patients with severe sperm deficiencies that researchers noticed something surprising. Eggs whose shells had been poked open were doing a much better job of sticking to the uterus wall. In a trial performed by Dr. Jacques Cohen, one of the scientists who developed the PZD procedure, embryos successfully lodged in the womb at a rate more than five times the national average for IVF. "I was so excited I couldn't sleep at night," says Cohen. Apparently eggs with a hole in their outer membrane somehow benefit from that hole. Cohen theorizes that embryos that...
...April scientists from Israel and the U.S reported a new finding that may offer yet another way to help infertile couples. It had long been assumed that there was no communication between egg and sperm until they collided in the Fallopian tube. But by closely watching the behavior of sperm in test tubes containing the fluid from an egg's follicular sac, an interesting effect was observed. A small number of sperm seemed to change their swimming patterns in response to chemicals secreted by the egg or cells around...
Scientists in South Korea are on the verge of a breakthrough in a procedure doctors have been dreaming about for some time: the freezing and storage of unfertilized eggs. Sperm and embryos are regularly frozen for later use, but not eggs, which quickly lose their viability when manipulated outside the body. But Dr. Kwang Yul Cha, an endocrinologist at Cha Women's Hospital in Seoul, reports that his team has produced two pregnancies from eggs matured not in an ovary but in a Petri dish -- a major step in the eventual perfection of egg freezing. Many scientists expect that...
Horror stories abound. It is not unusual for a poorly trained physician to schedule advanced infertility treatments -- even surgery -- on a woman without first checking her partner's sperm count. A lawsuit is pending against a physician in Torrance, Calif., who is accused of duping patients into believing he was performing in vitro fertilization when he wasn't even collecting eggs. Consumers are advised to seek guidance from either the American Fertility Society, based in Birmingham, or Resolve, a national infertility organization with headquarters in Somerville, Mass. "You need to be a careful consumer," warns Dr. Arthur Wisot, a Redondo...
Pamela and Jonathan Loew know about investing all their hopes and dreams in achieving pregnancy. The Los Angeles couple went through a five-year effort that included hormone treatment, artificial insemination, an ectopic pregnancy, sperm washing and finally GIFT. "Intellectually you know it's a medical problem," says Pamela, "but emotionally you can't get it out of your mind that you're not like a normal woman...
