Male Reproductive System Overview

The male reproductive system is responsible for producing and delivering sperm cells, the male gametes.

The testes produce testosterone, the primary male sex hormone, which plays a crucial role in male development and sexual characteristics.

Sperm cells are produced in the testes, which are located in the scrotum.

The epididymis is a coiled tube attached to the testes where sperm cells mature and are stored.

The process of transferring sperm cells from the male to the female reproductive system is called ejaculation. This involves the release of semen, a fluid containing sperm.

A pouch made of skin that holds the testes.

The organs responsible for producing sperm cells.

These small tubes inside the testes are where sperm cells develop.

In cold temperatures, the scrotum becomes firm and wrinkled to reduce its size, helping to keep the testes warm.

The testes are about 4-5 centimeters long, roughly the size of a large grape.

The male reproductive organ that delivers sperm into the female's reproductive system during mating.

The testes are responsible for producing sperm cells, which are crucial for fertilization in humans.

A sac that holds the testes and helps regulate their temperature for optimal sperm production.

A coiled tube attached to the testes where sperm cells mature and are stored.

The urethra carries sperm out of the body during ejaculation. It's a passageway for both urine and sperm.

Within the epididymis, sperm cells continue to mature and develop the ability to fertilize an egg.

The epididymis is a vital part of the male reproductive system, ensuring that sperm are fully functional before ejaculation.

The epididymis is a coiled tube and not a single, straight structure.

Sperm are stored in the epididymis until they are ejaculated.

The vas deferens is a tube that carries sperm from the epididymis to the ampulla of the ductus deferens.

The wall of the vas deferens is composed of smooth muscle, allowing for the rhythmic contractions that propel sperm during ejaculation.

The vas deferens originates from the epididymis, traverses along the back side of the testes, and joins with the blood vessels and nerves that supply the testes.

The vas deferens is a crucial component in the male reproductive system, enabling the efficient transport of mature sperm from the epididymis to the ejaculatory ducts.

The vas deferens is a long, coiled tube that can be surgically cut as a form of male contraception. This procedure, called a vasectomy, prevents sperm from reaching the ejaculatory ducts, preventing fertilization.

A tube that carries sperm from the seminal vesicles and prostate gland to the urethra, where it is expelled during ejaculation.

The ejaculatory duct joins the urethra within this gland.

Seminal vesicles and the prostate gland contribute fluids to semen.

It is responsible for transporting urine and semen outside the body.

The process of expelling semen from the penis, usually during sexual activity.

The lower portion or neck of the uterus.

A thick mucus produced by the cervix.

Cervical mucus becomes thinner and more slippery, allowing sperm to easily travel through it.

Cervical mucus lubricates the vagina during intercourse.

Cervical mucus can be used as a method of natural family planning.

The urethra is a tube that carries both urine and semen (male reproductive fluid) out of the body, but not at the same time.

The male urethra connects from the urinary bladder to the tip of the penis.

During ejaculation, a reflex causes the muscles controlling urine flow (sphincter muscles) to close tightly, preventing urine from mixing with semen.

Sperm travels through the urethra and exits the body during ejaculation.

Although the urethra carries both urine and semen, these fluids don't pass simultaneously.

Estrogen and progesterone are the female sex hormones, produced by the ovaries.

The ovaries produce eggs, also called ova, which are essential for fertilization.

The female reproductive system provides support and protection for the developing embryo during pregnancy.

The female reproductive system is designed to give birth to a new baby.

The female reproductive system includes organs like the ovaries, fallopian tubes, uterus, and vagina, all working together for reproduction.

A muscular organ where a fertilized egg implants and develops into a fetus.

The tubes that connect the ovaries to the uterus, where fertilization usually occurs.

The female reproductive organs that produce eggs and hormones like estrogen and progesterone.

The muscular tube that connects the uterus to the outside of the body.
