Study Notes
Male Reproductive System Overview
- Gonads function to produce gametes (sperm) and secrete sex hormones (testosterone).
- Testes are the male gonads responsible for both sperm production and hormone secretion.
Testes Structure and Function
- Interstitial cells in the testes produce testosterone, a key hormone for male development and sexual function.
- Sperm are formed in seminiferous tubules, which are tightly coiled structures within the testes.
- Testes have exocrine functions primarily related to sperm production.
Male Genitalia and Duct System
- The male external genitalia include the penis and scrotum, integral for external reproductive functions.
- The spermatic cord includes the ductus (vas) deferens, which transports sperm from the epididymis.
- The urethra serves a dual role, conducting both urine and semen out of the male body.
Sperm Maturation and Transport
- Sperm gain motility while maturing in the epididymis, essential for successful fertilization.
- During ejaculation, peristaltic waves move sperm from the epididymis through the ductus deferens, eventually reaching the urethra.
- The ejaculatory duct forms after the ductus deferens joins with the seminal vesicles, transporting sperm to the urethra.
Seminal Glands
- Seminal vesicles, located on the posterior surface of the urinary bladder, produce a nourishing fluid that activates sperm.
- Prostate gland surrounds the upper portion of the urethra and contributes to semen composition.
- Seminal glands, or vesicles, produce a thick, yellowish secretion important for sperm vitality.
Other Key Concepts
- The distal portion of the male urethra, known as the spongy urethra, runs the length of the penis.
- The glans penis is the enlarged tip of the penis, critical for reproductive function.
