Association between Thyroid Dysfunction and Male Infertility

– There is a high prevalence of thyroid disorder in the general population. Both hypo and hyperthyroidism have been attributed to male and female sexual dysfunction. The role of thyroid disorders in female infertility has been firmly established, while their role in male infertility is yet to be clearly defined. hyperthyroidism causes alterations in the sex steroid hormone metabolism as well as in spermatogenesis and fertility. Most of the studies conducted so far have shown that male patients with thyrotoxicosis have abnormalities in seminal parameters, mainly sperm motility. Severe, prolonged hypothyroidism, may impair reproductive function. Also, severe juvenile hypothyroidism may be associated with precocious puberty. There is paucity of researches studying the exact effect of thyroid disorders on male reproductive physiology. More researches are required to establish the relationship between thyroid dysfunction and male infertility.
