The medical history will be obtained and a physical examination performed.

A complete health history will be obtained including a menstrual history. Questions may include:

  • Are you sexually active?
  • Do you use birth control? What type?
• Quality
  • Was the previous menstrual period a normal amount?
  • Are the menses absent or decreased?
  • Do you usually have regular periods?
• Time pattern
  • When was your last menstrual period?
  • At what age did you have your first menstrual period?
  • Have you ever had normal periods?
• Aggravating factors
  • What medications do you take?
  • How much do you exercise?
• Other symptoms
  • What other symptoms are also present?
  • Is there breast tenderness?
  • Is there morning nausea and vomiting?
  • Is there a headache?
  • Is there a nipple discharge (and not breast feeding)?

  • Are there voice changes?
  • Are there changes in the breast size?
  • Is there excessive anxiety?

A physical examination, including a pelvic examination, will be performed. In patients with secondary amenorrhea, physical and pelvic examinations must rule out pregnancy before diagnostic testing begins. The patient may be encouraged to discuss her fears and, if indicated, may be referred for psychological counseling.

Diagnostic tests that may be performed include:

• Endometrial biopsy
• Progestin withdrawal
• Prolactin level
• Serum hormone levels such as testosterone levels
• Thyroid function studies
• Pregnancy test (serum HCG)
• FSH (follicle stimulating hormone level)
• LH (luteinizing hormone level)
• TSH (thyroid stimulating hormone; other thyroid function tests)
• Karyotype to rule out the presence of Y chromosome abnormality
• CT scan of the head may be done if a pituitary tumor is suspected

Intervention:
Treatment depends on the cause of the amenorrhea. If it is caused by another systemic disorder, normal menstrual function usually returns after the primary disorder is treated. For example, if the primary disorder is hypothyroidism, then amenorrhea will be cured when the thyroid disorder is treated with thyroid supplements.

Pituitary tumors are usually treated with bromocriptine, a drug that inhibits prolactin secretion. Surgery removal may also be suggested. Radiation therapy is usually reserved for situations where other medical or surgical treatment regimens are not successful.

Hormonal supplements are commonly utilized for those women who do not bleed in response to the progestin challenge test. Daily estrogen supplements are given in conjunction with intermittent progestin for 10 to 14 days per month every 1 to 3 months.

Women who bleed in response to the progestin challenge test are anovulatory --they do not menstruate because they do not ovulate. This common cause of amenorrhea is treated by inducing ovulation with medication such as clomiphene citrate (Clomid) -- but only if the patient desires pregnancy. In patients who have no immediate plan for pregnancy, on the other hand, oral contraceptive pills may be prescribed to induce cyclic menstruation to prevent uncontrolled growth of the endometrial lining.

Young women with primary amenorrhea, found to be caused by developmental abnormalities, may require hormonal supplementation, surgery, or both. In any case, psychosocial support and counseling for the patient and family is necessary to address specific concerns and provide guidance regarding anticipated sexual development.
