Study Notes
The Male Reproductive System
- The male reproductive system includes organs that produce, maintain, and transport sperm.
- It also produces male sex hormones and discharges sperm into the female reproductive tract.
- The system is made up of internal and external organs.
- The main function of the male reproductive system is to help urinate, have sexual intercourse, and create children.
External Genital Organs
- The penis is the male organ for sexual intercourse.
- It has three parts: root, body (or shaft), and glans (the cone-shaped head).
- The body of the penis has three chambers filled with erectile tissue that becomes engorged with blood during arousal, causing an erection.
- The scrotum is a pouch-like sac of skin that hangs behind the penis.
- It contains the testicles, nerves, and blood vessels.
- The scrotum protects the testicles and helps regulate their temperature, which is crucial for sperm production.
Internal Genital Organs
- The testes (testicles) are the primary male reproductive organs responsible for sperm production and testosterone production.
- They are located in the scrotum.
- Testosterone plays a vital role in male development and functions.
- The epididymis is a long, coiled tube attached to each testicle.
- It stores and matures sperm before they are transported to the vas deferens.
- The vas deferens is a tube that transports mature sperm from the epididymis to the ejaculatory duct.
- Accessory Glands:
- The seminal vesicles, prostate gland, and bulbourethral glands produce fluids that make up semen, the protective fluid surrounding sperm.
Hormonal Regulation
- The male reproductive system relies on hormones, primarily follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone.
- FSH and LH are produced by the pituitary gland and are essential for sperm production and testosterone production.
- Testosterone is crucial for male characteristics like muscle mass, bone density, and sex drive.
Sperm Production and Maturation
- Sperm production, called spermatogenesis, occurs in the seminiferous tubules within the testes.
- The Sertoli cells within the seminiferous tubules aid in sperm maturation.
- Testosterone, produced by the Leydig cells in the testes, is essential for spermatogenesis.
