What are Sertoli cells?
Sertoli cells are the somatic cells of the testis that are essential for testis formation and spermatogenesis

Where are Sertoli cells found?
Found in the seminiferous tubule
What are Leydig cells and what do they do?
- Leydig cells are interstitial cells of Leydig, are found adjacent to the seminiferous tubules in the testicle.
- Produce testosterone in the presence of LH
Can testicles swap sides?
No, as a scrotal septum separates the two testicles
Describe the process in which the testes push through the abdominal wall
- The testes evaginate the abdominal wall as they are pulled through by the gubernaculum
- This forms the spermatic fascia (made of layers of abdominal muscle)

What are the three fascial layers in the spermatic cord?
- Internal fascia
- Cremasteric fascia
- External fascia

Identify the three arteries supplying the spermatic cord
- Testicular artery
- Artery to vas
- Cremasteric artery

Identify the three veins draining the spermatic cord
- Testicular vein
- Vein to vas
- Cremasteric vein

Identify the three nerves innervating the spermatic cord
- Ilioinguinal nerve
- Nerve to cremaster (genital branch of genitofemoral nerve)
- Sympathetic

What does the prostate do?
- Maintains urinary continence (surrounds urethra)
- Creates an alkali secretion
- Propels seminal fluid into urethra during ejaculation

What are the functions of the penis?
- Expulsion of urine via urethra
- Deposition of sperm in female genital tract
Describe the processes that guide erection
- Vasodilatation in penile arterioles, and compression of veins results in erection (parasympathetic)
- Erection is terminated by vasoconstriction (sympathetic)
Which nervous system orchestrates ejaculation?
Ejaculation is a complex process primarily orchestrated by the sympathetic system
Which artery is the main blood supply to the penis?
Pudendal artery
