Why hormones are checked
Hormones guide ovulation, cycle regularity, egg development, and early pregnancy support. Testing can help explain irregular periods, absent ovulation, or repeated treatment difficulty.
Common tests may include AMH, TSH, prolactin, FSH, LH, estradiol, progesterone, and androgens depending on symptoms.
Timing matters
Some hormone tests must be done on specific cycle days. Others can be done at any time. The doctor or nurse will explain the timing.
Results should be interpreted with ultrasound findings and medical history, not in isolation.
Correcting treatable factors
Thyroid or prolactin abnormalities, for example, may need treatment before or during fertility care.
