ka manot apie sita ismysla, galetu but siek tiek tiesos ar ne jei ryski NT juostele mergytes laukiamasi jei blanki berniuko, nes kaip rasoma laukiantis mergytes xx yra dominuojancios manos organizme sutampa ir greit hcg dideja, xy, tas y - berniukai slopinami mamos organizme ir hcg buna mazesnis. aisku NT tai ne tyrimas laboratorijoj ale visvien tas pat hormonas reaguoja. ar kam pasitvirtino tai ?
There are plenty of old wives' tales regarding how to tell whether a pregnant woman is going to have a boy or a girl. But one thing that doctors know for certain is that in the second and third trimesters, women having girls display higher levels of a hormone known as maternal serum HCG (MSHCG) than do women pregnant with boys. Now new research suggests that such hormonal differences appear less than three weeks after conception. The findings, published today in the journal Human Reproduction, may help explain how girls and boys exert control over their mother's hormones.
Yuval Yaron of the Genetic Institute at Sourasky Medical Center in Tel Aviv and colleagues followed 347 pregnancies achieved through in vitro fertilization. The researchers tested the mothers' MSHCG levels between 14 and 20 days after fertilization and detected some differences as early as day 16. Three weeks into pregnancy, women carrying girls exhibited hormone levels 18.5 percent higher than those of their boy-carrying counterparts, regardless of factors such as previous pregnancies or maternal age.
