Male Internal Genitalia Anatomy

Male Reproductive Organs Location

• The male reproductive organs are located outside of the abdominal cavity, between the base of the penis and the anus.

Seminal Vesicles Function

• The seminal vesicles produce fluids that make up semen, which nourish and transport sperm during ejaculation.

Interstitial Cells Location

• The interstitial cells (cells of Leydig) are located in the testes and produce androgens (male sex hormones).

Bulbourethral Glands Function

• The bulbourethral glands produce a fluid that helps to neutralize acidity in the urethra and provides a lubricant during sexual arousal.

Epididymis Function

• The epididymis is a tube-like structure located behind each testicle, where immature sperm mature and are stored before entering the vas deferens.

Ductus Deferens Function

• The ductus deferens, also known as the vas deferens, is a muscular tube that stores and transports sperm from the epididymis to the ejaculatory ducts.

Supporting Cells

• Sertoli cells support and nourish immature sperm cells in the testes.

Sperm Maturation

• Maturation of sperm occurs in the epididymis, making them capable of fertilizing ova.

Sperm Storage

• The epididymis stores mature sperm in the lower portion or tail.

Ductus Deferens Origin

• The ductus deferens begins at the epididymis and joins the ejaculatory duct.

Ejaculatory Duct Formation

• The ductus deferens converges towards the base of the prostate, joining with the vas deferens to form the ejaculatory duct.

Urethra Function

• The urethra is a tube that carries semen and urine out of the body through the penis.

Prostate Gland Structure

• The prostate gland is located between the urethra and the two ejaculatory ducts.

Benign Prostate Hypertrophy

• Benign prostate hypertrophy occurs in the prostate gland, resulting in an enlarged prostate.
