Thyroid and male infertility

The functional state of the thyroid gland was evaluated clinically and by PBI for 104 infertile males and 25 normal controls. An euthyroid state was found to be fundamental for spermatogenesis. Hypothroidism was detected in 3 cases and a case record of azoospermic thyrotoxicosis is described with normalization of semen picture after medical control of the hyperthyroid state. Liothyronine therapy [20 ug/day] was very effective among infertile males with hypothyroidism and useless in euthyroidism. Study of the functional state of thyroid gland is essential before T 3 therapy
