MALE REPRODUCTIVE TRACT
The male reproductive tract, which delivers sperm to the female in a vehicle (semen) conductive to sperm viability, can be divided into a sequence of ducts and three major secretory glands. Moving from testes to penis, sperm pass through the epididymis, ductus (or vas) deferens, ejaculatory duct, and urethra (Fig. 1-1). The major accessory sex glands, which provide most of the semen, are the seminal vesicles, prostate, and bulbourethral gland. These organs include two testes that produce spermatozoa and ejaculatory ducts, epididymides (singular epididymis), bulbourethral (Cowper’s

) glands, as well as the following single structures: the prostate gland, the penis, the urethra, and the scrotum.
