Male Reproductive System

Flashcards covering key concepts from the lecture on the male reproductive system.

What does the scrotum do in the male reproductive system?

It provides a cooler temperature needed for sperm production.

What are the main components of the male anatomy?

Scrotum, testis, epididymis, ductus deferens, seminal vesicles, ejaculatory duct, prostate gland, bulbourethral gland, urethra, and penis.

What is the function of the spermatic cord?

It is a connective tissue tube that runs through the inguinal ligament and contains the ductus deferens, cremaster muscle, testicular nerve, and testicular vessels.

What hormones control sperm production?

FSH (Follicle Stimulating Hormone) and testosterone.

What structures are involved in the function of the testes?

Tunica vaginalis, tunica albuginea, septa, testicular lobules, seminiferous tubules, and efferent ductules.

What is the role of Sertoli cells?

Sertoli cells line the seminiferous tubules and assist with sperm development.

How many sperm are produced each day on average?

100-200 million sperm.

What are the segments of the urethra?

Prostatic urethra, membranous urethra, and spongy urethra.

What is the function of the seminal vesicles?

They produce fructose to nourish sperm, prostaglandins to widen the cervix, and bicarbonate to neutralize vaginal acid.

What is benign prostatic hyperplasia?

A noncancerous enlargement of the prostate that is very common in men over 80.

Describe the structure of the penis.

The penis has three erectile bodies: corpus spongiosum and two corpora cavernosa, along with central arteries, venous spaces, and dorsal veins.

What are the stages of the erection process?

Blood fills the erectile tissues, deep arteries dilate, and blood is trapped in erectile tissues by compression of veins.

What is the function of the prepuce?

The prepuce, or foreskin, covers the glans of the penis and is removed during circumcision.

What are barrier methods of contraception?

Methods that prevent sperm from entering the uterus, such as condoms and diaphragms.

What is the effect of oral contraceptives?
