Thyroid gland and epididymal function in rats. II. Sperm motile efficiency.
The epididymis is controlled by the endocrine system and plays an active role in the process of spermatic maturation. In order to extend these studies, our investigations were focused on the relationship between the hypofunction of the thyroid gland and the motility of the caput, corpus, and cauda epididymal spermatozoa. The hypofunction was associated with decreasing sperm motility efficiency. In thyroidectomized rats injected with T-3, no sperm motility changes were observed.
