Exams and Tests

A doctor may perform the following tests to determine the cause of the amenorrhea:

• Blood tests may be performed to determine the levels of hormones secreted by the pituitary gland (FSH, LH, TSH, and prolactin) and the ovaries (estrogen).



• Ultrasonography of the pelvis may be performed to assess the abnormalities of the genital tract or to look for polycystic ovaries.



• CT scan or MRI of the head may be performed to exclude pituitary and hypothalamic causes of amenorrhea.

If the above tests are inconclusive, additional tests may be performed.

• Thyroid function tests



• Determination of prolactin levels



• Hysterosalpingogram (x-ray test) or saline infusion sonography (SIS), both of which examine the uterus



• Hysteroscopy (visual inspection of the uterine cavity)
