Which organ(s) in the male reproductive system produce gametes?
Correct answer: C. Seminiferous tubules
- A. Vas deferens
- B. Malpighian tubule system
- C. Seminiferous tubules
- D. Ejaculatory duct
- E. Testicular Duct System
Explanation
In mammals production of testes occurs in the seminiferous tubules of the male testes.The male genitals include the testes, the ductus deferens, the seminal vesicles, the ejaculatory ducts, and the penis, together with the following accessory structures: the prostate and the bulbourethral glands.The testes are two glandular organs, which secrete the semen; they are suspended in the scrotum by the spermatic cords.Testosterone is the principal hormone in a group of hormones called androgens. In men, testosterone is produced by the testes, in women, testosterone is primarily secreted by the ovaries.It is derived from cholesterol (like all the sex hormones) and its immediate precursor is DHEA.
