Results: The results showed that:(1) The three types of NOS immunoreactivity were not found in rat testis until 30 days after birth;(2) NOS1 immunoreactivity was found in a few spermatocytes in rat testes on postnatal 30 days, and in spermatozoa present at the lumen surface of seminiferous tubules and some Leydig cells on postnatal 60 days;(3) NOS2 immunoreactivity appeared in a few spermatocytes, Sertoli cells and peritubular myoid cells on postnatal 30 days. On postnatal 60 days, NOS2 immunoreactivity appeared in some Leydig cells, peritubular myoid cells, Sertoli cells, very few spermatocytes and the head of immature spermatozoa in some seminiferous tubules;(4) NOS3 immunoreactivity was detected in a few spermatocytes on postnatal 30 days, as well as in the smooth muscle cells of blood vessels on postnatal 30 days and 60 days.
