Male Reproductive System Flashcards
Scrotum
Ruggated, skin-covered, muscular pouch suspended from the perineum. It supports the testes.
- Its important function is it regulates the temperature of the sperm– necessary for the life of the sperm. Namamatay ang sperm due to a sudden change in temperature. If the male is feeling cold, the testes contracts so that it moves close to the body. If the body is feeling hot, the scrotum relaxes so that it falls away from the body
Testes
aside from being a gonad, it is also an endocrine gland. It produces two things: (1) sperm cells, and (2) hormones.
Note that left testes is slightly larger and lower than the right.
- When you palpate it, it should be firm, soft, and egg-shaped.
- Testes should be palpated upon birth to check its presence. If hindi naka descend, may cryptorchidism yung bata. (undescended testes; magkakaproblem sa
fertility yung bata in the future kung hindi agad magagamot).
Seminiferous Tubules
The actual sperm-forming factories.
Interstitial Cells (Leydig Cells)
Produce androgens (testosterone).
Glans Penis
- actual penis
Prepuce
– foreskin; ito yung tinatanggal kapag nagcicircumsize.
what happens to the penis when sexual excitement occurs?
With sexual excitement, blood flow to the penis increases and causes dilation of arteries which then contracts the ischiocavernosus muscle resulting in an erection.
Duct System
“daluyan”
Epididymis
provides temporary storage for immature sperm and while sperm travels epididymis, they mature, gaining ability to swim
Ductus Deferens
Propel live sperm during ejaculation from epididymis to urinary bladder, and enclosed along with blood vessels and nerves in a connective tissue called spermatic cord
Urethra
Extends from base of urinary bladder to penis which carries sperm and urine to exterior body part
What is Accessory Structures and name the 3
produces fluids na humahalo sa sperm as it exits the urethra
Seminal Vesicles
Prostate Gland
Bulbourethral Glands
Seminal Vesicles
Found at the base of the bladder and joins ductus deferens which then produce seminal fluid which nourishes and activates sperm passing.
Prostate Gland
Encircles upper part of urethra and below urinary bladder which secretes milky fluid that plays a role in activating sperm
Bulbourethral Glands
Inferior to prostate gland and produce thick, clear mucus which cleanses urethra of acidic urine and serves as lubricant during sexual intercourse.
