Lecture 04 - Male Reproductive System

Question 1

Testis Taxonomy(!)

Answer 1

Seminifer tubules –> Rete Testis –> Efferent Ducti –> Epididymis

Question 2

Epididymis: General Characteristics

Answer 2

4-7 m inside 5 cm
A place for development of sperms
From superior pole of testis to inferior pole
Vase difference: vasomuscular
Head, Body, Tail
Appendix
Attached to tunica albogina

Question 3

Epididymis: Sinus

Answer 3

Inside tunica vaginalis

Separates it from testis

Question 4

Epididymis: Epididymitis

Answer 4

Uncommon

Intrinsic or retrograde

Question 5

Testis: Aterial Supply

Answer 5

1. Testicular
2. Obturator
3. Superior Vesical
4. External Pudendal
   Torsion

Question 6

Testis: Veinous Supply

Answer 6

Panpiniform reticule –> testicular veins
Right: inferior vena cava
Left: renal v.
Panpiniform:
Temperature regulation
Varicocele: temperature regulation + burning. Common in left testis

Question 7

Testis: Lymph

Answer 7

Paraaortic lymph nodes

Little to vascular roads

Question 8

Testis: Innervation

Answer 8

Sypathic: L1-3, vasomotor, constrictor
Parasympathic: S2-4, vasomotor, dilator

Question 9

Vase Difference: General Characteristics

Answer 9

Vasomuscular

Assisted Reproductive Tecnology

Question 10

Seminal Vesicle: General Characteristics

Answer 10

Between rectum and bladder
Retroperitoneal
Palpable in pathologic forms
Secretes most if semen

Question 11

Seminal Vesicle: Effects

Answer 11

1.Effective in fertilization:
A. Zn: disulfid glutamine bonds –> increase of sperms’ nucleus density
B. Fructose: sperms food
2. PG: facilitates fertilization and sperm movement
3. Facilitates sperms movement

Question 12
