...company, Fertility & Genetics Research Inc., seemed promising. But the procedure was cumbersome--it involved flushing embryos out of the uterus of the egg donor--and was soon eclipsed by in-vitro fertilization. Ultimately the venture failed. Indeed, Seed in recent years appears to have suffered some financial reversals. Until last summer he and his third wife Gloria lived in a two-story Victorian house in Oak Park. But the bank foreclosed on their $341,000 mortgage, and they were forced to move to a modest bungalow in nearby Riverside. "I had a beautiful house," sighs Seed. "It's very difficult...
...same holds true for many other experimental therapies emerging from the lab. One of the most promising is a technique that keeps embryos growing for a few extra days in a Petri dish. Until recently, clinicians had to put in-vitro embryos into the uterus when they were just one or two days old and relatively fragile. After that, the embryos' metabolism changes, rendering standard growth mixtures useless for nourishing them. That's why clinics insert several at once, which raises the odds of success but often produces triplets, quads and even quints...
...drug called tamoxifen, which works by blocking estrogen's ability to stimulate breast tissue, they discovered that it also helped prevent osteoporosis. The drug seemed to act like an estrogen in the bone but an anti-estrogen in the breast. Unfortunately, it also acted like an estrogen in the uterus, dramatically increasing the risk of uterine cancer. So researchers set out to find a chemical cousin of tamoxifen that would be easier on the uterus...
...Every year thousands of hammerhead pups are born in Kaneohe Bay, on the east shore of Oahu. (About 40% of shark species lay eggs; the rest bear live young, and some of these carry their young just as mammals do, with an umbilical cord connecting the fetus to the uterus.) For the next 12 months or so, the baby hammerheads are an integral part of the region's ecosystem...
...FIBROIDS in retreat? A preliminary trial finds that the benign tumors shrink markedly when doctors inject uterine arteries with a solution containing tiny plastic particles. The injections cut off the blood supply to the fibroids--apparently without harming the uterus...
