What sex assignment should an indivisualwith abnormal sex chromosom have? Is a Klienfelter's syndrome child a male with and extra X? Or a female with a superfluous Y? A Klienfelter's child is usually assigned as male, the gonads are small, always sterile, and produce little androgen and some estrogen. As an adult the individualmay have somewhat mixed somatic features, taller than average, a tomboyish figure or eunuch body depending on body fat levels, minor breasts developement, lack of upperbody strenght, and feminine hair distribution. There is believed to be a slight chance of mild mental retardation or learning disabilities and the brain sex is often ambigiousto female. It is not unusual for an individual with Klienfelter's Syndrome to be also Homosexual or Transsexual. Treatmentwith hormones is usually recommended by physicians to better fit typical male or female somatic expression, testerone for male identified individuals, estrogen and progesterone for female identified individuals.
What sex is a XX chromosome child with SRY gene transfered onto it? There are a genes normally on the Y chromosome that ocasionally get transfered or transposed onto the X chromosome.Such individuals look like Klien Felter's save that they are not as tall, nor do they have the slight mental retardation. They are however sterile. Brain sex is ambigious to female. Treatment is the same as Klienfelter's.
Occasionally the SRY gene is missing from the Y chromosome. This leads to a female appearance but sterile gonads. Brain sex is usually female.
