Document Summary
The fetus is initially undifferentiated in regard to sex (without exposure to male hormones, all babies would be born with female physical appearance and behavior) Individuals with this disease have normal female genitalia but the ovaries develop abnormally. Unidentified regions on the x chromosome are responsible for development of ovaries but having only 1 x chromosome interferes in this process. In most cases, the ovaries don"t produce either the ova or normal levels of female hormones which leads to infertility but when the x chromosome is missing in some but not all cells, women may be fertile. Women with turner syndrome are short and may have increased skin folds at the neck; intelligence is normal but specific deficits in spatial relationships and memory can occur. It is associated with normal intelligence along with cognitive deficits and social awkwardness: delayed, reduced verbal skills, left-handedness, brain lateralization is affected along with localization of specific functions.
