...University of Bologna both say recent technical advances have boosted success rates to the same level as embryo freezing, which is about 20%. In Porcu's most recent studies, 70% to 80% of the eggs survived the defrosting process without breaking down. Kim puts the current frozen-egg birth rate at 21%, based on a recently completed study in which 6 out of 28 women in South Korea became pregnant and later gave birth. One even had twins...
...born and with more than 30,000 children in the U.S. conceived in vitro each year, a controversial study recently suggested that those babies have a higher risk of genetic damage. "We need to have 700 or 800 babies to prove statistically that there is no increase in birth defects [for frozen-egg babies]," says Dr. Michael Opsahl of the Genetics and IVF Institute in Fairfax, Va. Kim doesn't buy that argument: "The bottom line is, Can you produce a baby? We say yes." He adds that the chromosomal tests done on his babies have so far come...
While a recent U.S. study concluded that the odds of first cousins producing children with birth defects may have been overstated, the risk is still almost double that for unrelated couples. Denizens of the incest villages see ample evidence of this. Near the city of Yan'an, a brother and sister squat in the mud-brick slums, signing a secret language to each other: both Cao Shuai and Cao Jing were born deaf, to parents who are first cousins. This spring in Yan'an county, a severely retarded newborn girl was found abandoned beside a road. Authorities tracked down...
...female shortage in China is only worsening. In 2000, 900,000 fewer female births were recorded than should have been, based on male births. In 1990 the shortfall was 500,000. Some of that owes to parents giving up daughters for adoption without registering their birth. But population experts at the Chinese Academy of Social Sciences in Beijing estimate that up to one-third of the girls are missing because of gender-based abortions. Rural Chinese women also tend to breast-feed girls for shorter periods, providing less hope for survival. Chinese demographers estimate that in some rural areas...
...prerelease news about Papa Roach's second album, lovehatetragedy, was that lead singer Coby Dick had reverted to the use of his birth name, Jacoby Shaddix. That's a fine name for a personal-injury law firm, but it's not much of an upgrade from Coby Dick for a rock star. Changing hardly seems worth the trouble. But the new/old name, like much of lovehatetragedy, is evidence of how metal has evolved over the past decade. Cartoon bands like Motley Crue and Poison once sang about sex and cars and sex in cars; then Kurt Cobain came along...
