Study Notes
Male Reproductive System
- The deferent duct lies in the spermatic cord.
- The tunica vaginalis forms the outer covering of the testis.
- The function of the tunica vaginalis is to encase and protect the testes.
Sperm Transport
- The vas deferens transports sperm from the testes to the urethra.
- The primary function of the male reproductive system is to produce and deliver sperm.
Glands and Semen
- The seminal vesicles contribute to the composition of semen.
- The function of the seminal vesicles is to produce secretion for sperm nutrition.
- The seminal vesicles are located lateral to the bladder.
- The prostate gland is responsible for producing the majority of seminal fluid.
- The bulbo-urethral glands produce pre-ejaculate fluid.
Testes
- The tunica albuginea is a dense fibrous covering of the testis.
- The parenchyma of the testis is divided into lobules by septula.
- Each testis typically contains 250-300 lobules.
- The function of Leydig cells is to produce androgens.
- The convoluted seminiferous tubules support spermatogenesis.
Epididymis
- Sperm mature and become motile in the epididymis.
- The epididymis is located posteriorly to the testis.
- The epididymis is connected to the deferent duct by the rete testis.
- The length of the deferent duct is 40-50 cm.
Spermatic Cord
- The spermatic cord is divided into three parts.
- The deferent duct becomes the ejaculatory duct at the ampulla.
Scrotum
- The scrotum is located between the thighs.
- The dartos muscle regulates temperature in the scrotum.
- The cremasteric fascia is derived from the abdominal fascia.
