sex chromatins การใช้

Other methods may be : research of high serum levels of gonadotropins ( follicle-stimulating hormone and luteinizing hormone ), presence of azoospermia, determination of the sex chromatin, and prenatally via chorionic villus sampling or amniocentesis.
Such anaphase lag could account for the largest minority of karyotypes, the mosaics XY / XXY and XX / XXY . Eighty percent of these patients have positive sex chromatin, and their karyotypes may vary widely, and with many mosaics.
The sex chromatin test was, at the time, the first step in the gender verification process, and not intended to provide a definitive and final decision, but officials from the International Olympic Committee and the International Association of Athletics Federations routinely advised athletes to fake an injury after such a test so they could withdraw from competition quietly and protect their privacy.
