MALE REPRODUCTIVE SYSTEM
The primary sex organs of the male are called gonads, specifically the testes(singular, testis). Gonads produce gametes
(sperm) and secrete sex hormones. The remaining accessory reproductive organs are the structures that are essential
in caring for and transporting sperm. All of these organs and structures are designed to accomplish the male’s repro-
ductive role of producing and delivering sperm to the female reproductive tract, where fertilization can occur.
These structures can be divided into three categories:
- Sperm-transporting ducts, which include the epididymis, vas deferens (or ductus deferens), ejaculatory duct,
and urethra - Accessory glands, which include the seminal vesicles, prostate gland, and bulbourethral glands
- Copulatory organ, called the penis, which contains erectile tissue. (See Fig. 8–9.)
