Stallion Reproductive System By: K. Matthews Modified 2010 by B. Purswell

What is the function of the male reproductive system? Produce sperm and hormones – Testosterone Storage and maturation of sperm Produce semen Copulatory organ (penis) delivers semen to female

Components Testes Epididymis Spermatic cord Vas Deferens Accessory Sex Glands Penis Sheath

Testes Primary organ of reproduction in male Produce sperm and male sex hormones – Testosterone Do not remain inside body cavity – Chriptorchid – In-fertility

Testes

Scrotum Aids in temperature control of the testes Support of the testes Protection of the testes

Scrotum

Testes/Scrotum

Spermatic Cord Contains life-support vessels Aids in regulating temperature of testes Supports the testes

Spermatic Cord

Epididymis Concentration of spermatozoa (sperm cells) Storage of spermatozoa Transport of spermatozoa Maturation of spermatozoa

Epididymis

Vas Deferens Transport of spermatozoa to accessory glands

Accessory Sex Glands Vesicular Gland – Contributes fluid, energy substrates, buffers to semen Prostate Gland – Contributes fluid to semen Bulbourethral Gland – Flushes urine residue from urethra

Accessory Sex Glands

Urethra Transports semen

Glans Penis Male organ of copulation

Sheath Encloses and protects free end of penis
