Hormone tests

 measuring male hormone levels.

Measuring the blood levels of FSH, LH, testosterone and prolactin are essential in selected cases. Normal sperm production and sexual function are dependent on normal hormonal environments. The measurement of FSH and LH levels can be valuable in distinguishing patients with azoospermia. Those patients who have azoospermia due to an obstruction have normal FSH levels, meanwhile those patients whose testes are not making sperm have raised FSH levels. Low levels of FSH and LH may indicate that the pituitary gland is not producing enough hormones and there is therefore the possibility of effective hormone treatment.
