Male Reproductive

Testes

Testes

Male reproductive organs responsible for producing sperm and testosterone.

Seminiferous Tubules

Tubular structures within the testes where sperm production (spermatogenesis) takes place.

Efferent Ductules

Ducts that carry sperm from the testes to the epididymis.

Epididymis

A coiled tube connected to the testes where sperm matures and is stored.

Seminal Vesicles

Glandular structures that produce a significant portion of the seminal fluid, providing nutrients and support for sperm.

Prostate Gland

A gland that produces a milky fluid that contributes to semen, providing nutrients and helping with sperm motility.

Bulbourethral or Cowper’s Gland

Glands that secrete a clear, lubricating fluid into the urethra during sexual arousal to neutralize acidity.

Sperm - Acrosome, Head, Midpiece, Tail (Flagellum):

Acrosome

A cap-like structure at the head of a sperm cell containing enzymes to facilitate penetration of the egg.

head

Contains the genetic material (nucleus) of the sperm.

Mid body

Contains mitochondria, providing energy for the sperm.

Tail

The whip-like structure that propels the sperm forward.

Cremaster Muscle

A muscle that helps control the position of the testes in response to temperature changes.

Dartos Muscle

A smooth muscle that contracts or relaxes to regulate the temperature of the testes by altering the surface area of the scrotum.

Scrotal Septum

A wall of connective tissue that divides the scrotum into two compartments, each housing one testis.

Scrotum

The external pouch of skin and muscle that houses the testes.

Semen

The fluid expelled during ejaculation, containing sperm and secretions from the seminal vesicles, prostate gland, and bulbourethral glands.

Circumsicion

Surgical removal of the foreskin, the fold of skin covering the head of the penis.

Foreskin

The fold of skin covering the head of the penis.

Impotence

Also known as erectile dysfunction, the inability to achieve or maintain an erection sufficient for sexual activity.

Vasectomy

A surgical procedure for male sterilization, involving the cutting or sealing of the vas deferens to prevent sperm from reaching the semen.
