Turner syndrome only occurs in females.Noonan syndrome, sometimes inappropriately called male Turner syndrome, can occur in males or females. It is an autosomal dominant genetic disorder and is not a chromosomal disorder. It is unrelated to Turner syndrome.

Turner syndrome is caused by a missing or incomplete X chromosome. People who have Turner syndrome develop as females. The genes affected are involved in growth and sexual development, which is why girls with the disorder are shorter than normal and have abnormal sexual characteristics.
Turner syndrome is typically caused by what is called nondisjunction. If a pair of sex chromosomes fails to separate during the formation of an egg (or sperm), this is referred to as nondisjunction. When an abnormal egg unites with a normal sperm to form an embryo, that embryo may end up missing one of the sex chromosomes (X rather than XX). As the embryo grows and the cells divide, every cell of the baby's body will be missing one of the X chromosomes.
Interesting facts about Turner syndrome
Turner Syndrome affects 60,000 females in the United States. This disorder is seen in 1 of every 2000 to 2500 babies born, with about 800 new cases diagnosed each year.
In 75-80% of cases, the single X chromosome comes from the mother's egg; the father's sperm that fertilizes the egg is missing its sex chromosome.
A female fetus (normally XX) can survive with only one X chromosome, but a male fetus (normally XY) could not survive with only one Y chromosome. This is because not having an X chromosome is much worse than not having a Y chromosome. The Y chromosome carries very few genes essential for life. In contrast, the X chromosome is a much longer DNA molecule and contains many, many genes that are needed for cells to function.
