Common Causes of Primary Amenorrhea - According to statistics, primary amenorrhea occurs in less than one percent of teenage girls in America Common causes of primary amenorrhea include:

* Abnormalities of chromosomes can cause premature decline of eggs in the ovaries and follicles, which play a role in ovulation and menstruation.
* Hypothalamus disorders or functional hypothalamic amenorrhea may cause another. The hypothalamus is located at the base of the brain. Among other things, it controls the hormones responsible for managing the menstrual cycle. Normal function of the hypothalamus may be disturbed by excessive exercise, eating disorders, physical and even psychological stress. This can lead to amenorrhea. Although very rare, tumors can prevent the hypothalamus also functioned normally.
* Pituitary disease or tumor can also inhibit normal pituitary gland function. Pituitary gland is another part of the brain that plays a role in regulating the menstrual cycle.
* Lack of reproductive organs can occur during fetal development. This can cause a girl born without some major parts of the female reproductive system (womb ie, cervix or vagina). Without a well developed reproductive system, menstrual cycle would not be possible.
* Structural abnormality of the vagina or the vaginal walls that prevent the membrane can prevent the signs of menstrual bleeding. A membrane wall such as this can impede blood flow out of the uterus and cervix.
