Male reproductive organs that produce sperm cells and testosterone.

Coiled tubes within the testes where sperm cells develop and mature.

Immature sperm cells found near the edge of the seminiferous tubules.

Fully mature sperm cells, capable of movement, found in the center of the seminiferous tubules.

The male reproductive system is responsible for producing sperm cells, male hormones, and delivering sperm to the female reproductive system.

The testes are the primary male reproductive organs that produce sperm cells and the male sex hormone testosterone.

Cells within the testes that release hormones essential for sperm development.

The scrotum is a sac of skin that holds the testes. It helps regulate the temperature of the testes, which is essential for sperm production.

Cells in the testes that primarily produce testosterone.

Muscles that contract to move cells and substances within the seminiferous tubules.

The epididymis is a long, coiled tube located on the back of each testicle. It is where sperm cells mature and are stored.

A pouch of skin that holds the testes, maintaining a slightly lower temperature ideal for sperm production.

The vas deferens is a long tube that carries mature sperm cells from the epididymis to the urethra.

The prostate gland is a small gland located below the bladder. It produces a fluid that helps nourish and protect sperm cells.

The urethra is a tube that carries urine from the bladder and, in males, also carries sperm cells from the vas deferens to the outside.

The penis is the external organ of the male reproductive system. It is involved in both sexual intercourse and urination.

The sensitive tip of the penis, containing the opening for the urethra.

Erectile tissue in the penis that fills with blood during arousal.

Glands that contribute fluids to semen, making sperm more mobile.

The structure that supports the vas deferens and blood vessels.

Glands that produce fluids that nourish sperm and increase fertilization chances.

A pair of muscles that help regulate the temperature of the testes by pulling them closer to the body for warmth.

The forceful expulsion of semen from the male body during sexual intercourse, containing sperm cells.

The process by which sperm cells are broken down and reabsorbed by the body if they aren't released during ejaculation.

A surgical procedure that involves cutting or blocking the vas deferens, preventing sperm from being transported out of the body.

The process of producing sperm cells in the male reproductive system.

Male reproductive organs that produce sperm cells and testosterone.

A sac of skin that holds the testes. It helps regulate their temperature for optimal sperm production.

The tube that carries urine from the bladder and, in males, also carries sperm cells from the vas deferens to the outside.

The external organ involved in both urination and sexual intercourse.

The tubes that transport mature sperm cells from the epididymis to the urethra.

Glands that produce fluids that contribute to the volume and quality of semen.

Fluid that contains sperm cells and secretions from accessory glands. It nourishes and protects sperm cells and helps them move.

Testosterone, produced by the testes, is the primary male sex hormone. It controls changes during puberty and triggers sperm production.

Spermatogenesis is the process of sperm cell creation and maturation, taking place within the testes.

The bulbourethral glands release secretions that neutralize vaginal acidity, while the prostate gland contributes substances enhancing sperm motility.

The main components of human semen are secretions from the bulbourethral glands (5%), prostate gland (30%), and seminal vesicles (65%).

The penis is the intromittent organ in humans, used for depositing sperm into the female reproductive tract.

The male reproductive system releases a mix of fluids and sperm cells known as semen or ejaculate. These fluids help nourish and protect the sperm during their journey.

Gametogenesis is the biological process of creating gametes (sex cells). In males, this process is called spermatogenesis.
