The seminiferous tubule, which is surrounded by a layer of epithelial cells from which the spermatozoa are produced, is one of the coiled, threadlike tubules that make up the majority of the testis.
A hormone mostly produced in the testes is testosterone (part of the male reproductive system). It is necessary for the formation and maintenance of masculine sex traits like facial hair, a deep voice, and muscle development.
No, sperms are produced by seminiferous tubules.
The Leydig cells situated in between the seminiferous tubules produce and secrete testosterone.
Thus, Seminiferous Tubules do not produce testosterone.
