The male reproductive system consists of the outer parts like the penis, testes, and scrotum, and inner parts like the prostate gland, vas deferens, and urethra. Your ability to have babies and your manly characteristics rely on how well your reproductive system works, along with the hormones sent out by your brain.

What is the Male Reproductive System?
The organ system in males that is responsible for the production and transfer of male germ cells is known as the male reproductive system. The male germ cells are also called Sperms.

How Male Reproductive System Works?
- Penis: This is the organ used for urination and sexual intercourse. It can become erect when filled with blood.
- Scrotum: This is a loose pouch of skin behind the penis that holds the testes.
- Testes (or testicles): These are egg-shaped glands located inside the scrotum. They produce sperm and testosterone, which is a hormone important for male characteristics.
- Epididymis: This is a coiled tube behind the testes where sperm mature and begin to move.
- Vas deferens: This is a thick tube connected to the epididymis that carries sperm to the urethra.
- Prostate gland: This walnut-sized gland sits in the pelvis and produces fluids that nourish sperm.
- Urethra: This is a tube that carries both urine and sperm from the bladder to the tip of the penis.
- Seminal vesicles: These are small glands near the prostate that contribute fluids to semen.
- Brain: The brain controls the release of sex hormones and plays a role in arousal.
Understanding the male reproductive system is important for understanding human biology and health.

Male Sex Accessory Ducts and Gland
The male reproductive system has various parts that work together for reproduction. These include the vasa efferentia, epididymis, vas deferens, and rete testis, which store and transport sperm. There are also accessory glands such as the seminal vesicles, prostate glands, and bulbourethral glands, which contribute fluids to semen.
The seminal vesicles produce about 60% of the fluid in semen. This fluid has a basic pH to balance the acidic environment of the vagina, and it contains fructose, which provides energy for sperm, as well as mucus and enzymes that help sperm function. The prostate glands contribute around 30% of the fluid, which contains citrate, calcium, and an enzyme called prostate-specific antigen. This enzyme helps to liquefy the semen before ejaculation.

The Cowper gland adds a small amount of fluid to semen. Overall, these glands work together to support sperm function and reproduction.
How does the male reproductive system function?
The male reproductive system relies on hormones, which are special chemicals that control different activities in the body. These hormones play a crucial role in keeping the male reproductive organs working properly. Here are the main hormones involved:
Follicle-stimulating hormone (FSH): This hormone is produced by a gland in the brain called the pituitary gland. FSH is essential for making sperm, which is the process known as spermatogenesis.
Luteinizing hormone (LH): Also produced by the pituitary gland, LH helps in continuing the process of spermatogenesis.
Testosterone: Testosterone is the primary sex hormone in individuals assigned male at birth (AMAB). It’s responsible for various changes in the body, such as building muscle, regulating fat distribution, increasing bone density, and influencing sex drive or libido.
What are the internal parts of the male reproductive system?
The male reproductive system consists of several important parts that play vital roles in the process of reproduction:
Vas deferens: Think of it as a long, muscular tube that carries mature sperm from the testicles to the urethra. This journey happens when a man ejaculates.
Ejaculatory ducts: These ducts are formed when the vas deferens joins with ducts from the seminal vesicles. As they pass through the prostate gland, they gather fluids that mix with sperm to create semen, which is eventually released through the urethra.
Urethra: This tube is responsible for carrying both urine and semen out of the body. In men, it’s also the pathway through which semen is ejaculated during sexual climax.

Seminal vesicles: Picture them as sac-like pouches located near the base of the bladder. They produce a significant portion of the fluid found in semen, including fructose, which provides energy to sperm.
Prostate gland: It’s a small gland positioned just below the bladder and in front of the rectum. It secretes a fluid that mixes with sperm to form semen. The urethra runs through the middle of this gland.
Bulbourethral (Cowper) glands: These are small glands situated near the urethra, just below the prostate gland. They produce a clear fluid that serves to lubricate the urethra and neutralize any acidity left over from urine.
All these components work together seamlessly to produce, store, and release sperm during sexual activity, ultimately facilitating the process of reproduction.
