| Seminal vesicle | one of two sac-like structures behind the bladder and connected to the vas deferens on each side; secretes an alkaline substance into the semen to enable the sperm to live longer |
| Semen | a mixture of the secretions of the testes, seminal vessels, prostate, and bulbourethral glands discharged from the male urethra during orgasm (semen= seed) |
| Ejaculatory duct | duct formed by the union of the (vas) deferens with the duct of the seminal vesicle; its fluid is carried into the urethra |
| Prostate gland | trilobular gland that encircles the urethra just below the bladder and secretes an alkaline fluid into the semen (pro= before; stat= to stand); also called prostate |
