Preview

Secondary hypogonadism is a biochemical finding, not a final diagnosis; hypopituitarism, hyperprolactinaemia, and/or a parasellar lesion must always be considered. Micropenis, scrotal hypoplasia, and/or bilateral cryptorchidism in an infant strongly suggest congenital secondary hypogonadism and mandate referral to a paediatric endocrinologist. Pituitary tumours associated with hyperprolactinaemic hypogonadism must not be automatically assumed to be prolactinomas. Secondary hypogonadism is an under-appreciated feature of both critical illness and chronic disease. It is one of the very few treatable causes of male factor infertility.
