Study Notes
Male Reproductive System: Organ Functions & Development
- Secondary Sex Organs: The following are NOT secondary sex organs in the male reproductive system: Testes
- Hormonal Activation: During adolescence, a burst of hormones activates the maturation of the testes at approximately age 10 to 14.
- Cryptorchidism: Undescended testes at birth is a condition known as cryptorchidism.
- Chromosomal Pattern: The normal chromosomal pattern for males is XY, while for females it is XX.
- Primary Sex Organ: The primary sex organ in the male reproductive system is the testes.
- Secondary Sex Characteristics: Features considered as secondary sex characteristics in males include deepening of the voice, growth of facial and body hair, increased muscle mass, and skeletal growth.
- Interstitial Cells Location: The interstitial cells (cells of Leydig) are located in the spaces between seminiferous tubules within the testes.
- Dartos Muscle Function: The dartos muscle in the scrotum contracts to wrinkle the scrotal skin, reducing heat loss.
- Cremaster Muscle Function: The cremaster muscle in the male reproductive system functions to elevate the testes, moving them closer to the body for warmth or during sexual arousal.
- Mature Sperm Storage: Mature sperm are stored in the epididymis of the male reproductive system.
- Spermatic Cord Role: The spermatic cord suspends the testes and contains structures like blood vessels, nerves, and the ductus deferens.
- Ductus Deferens Function: The ductus deferens (vas deferens) transports sperm from the epididymis towards the ejaculatory duct.
- Ampulla Formation: Each ductus deferens enlarges to form an ampulla near the prostate gland in the male reproductive system.
- Ejaculatory Duct Role: Each ejaculatory duct serves to transport sperm from the ampulla to the prostatic urethra, where it joins the prostatic secretions.
