Why Get Tested?

To evaluate the function of your pituitary gland, which regulates the hormones that control your reproductive system

When to Get Tested?

If you are having difficulty getting pregnant or are having irregular menstrual periods (in order to identify or rule out ovarian failure/menopause in women and sperm production failure in men); if your doctor thinks that you have symptoms of a pituitary, ovarian, testicular or hypothalamic disorder; when your doctor suspects that a child has delayed or earlier than expected sexual maturation (or delayed or early growth).

Sample Required?

A blood sample taken from a vein in your arm

Test Preparation Needed?

No special preparation is required for the test, but the blood sample should be taken at the start of a woman's cycle (days 1 to 4 if the cycles are regular)
