Male Reproductive

Question 1

Characteristics of Tunica Albuginea

Answer 1

Septa and Media Stinum

Question 2

Where do Leydig Cells reside?

Answer 2

Between Semineforous tubules

Question 3

Leydig Cells are typical steroid producing cells characterized by..

Answer 3

1. Smooth ER
2. Lipid Droplets
3. Mitochondria with tubular cristae

Question 4

Steroid (testosterone) produced by Leydig cells can do the following:

Answer 4

1. Maintain Spermatogenesis
2. Maintain accessory glands of reproduction
3. Secondary sex charactersitcs (facial hair, muscles)
4. Libido (sex drive)

Question 5

Androgen Insensitivity Hormone

Answer 5

Male genotype (XY) but female phenotype and infertile

Question 6

Sertoli cells have 3 functions what are they

Answer 6

2 on other cards,

3. Cells are necessary for germ cell viability (sustentacular role)

Question 7

Spermatogenesis VS Spermiogenesis

Answer 7

spermATOgenesis: The many mitosis and meiosis times that a spermatogonia must under go to become a spermatid (entire process)

sperMIOgenesis: Differentiation that occurs between round to elongated spermatozoa

Question 8

DNA replication and division (4n, 2n, 1n)

Answer 8

4n-Primary Spermatocytes
2n- Secondary Spermatocytes
1n- (haploid) are spermatid

Question 9

Cycle of Seminiferous Epithelium

Answer 9

All germ cells in stage 1 will uniformly divide and differentiate into next set of cells in stage 2 then uniformly differentially and divide to cells in stage 3. the whole process takes about 53-74 days in men. Then sperm is released and Stage Vi will differentiate to cells in stage 1 (it’s a cycle).
-Sequqence of time (temporal sensation) facillitated bc germ cells have incomplete cytokinesis

Question 10

Epididymis (ductus epididymis) is one long duct (7meters) that is covered by…

Answer 10

Pseudostratified columnar epithelium with STERIOCILIA which concentrates sperm into lumen of epididymus

Question 11

Sperm Maturation in Epididymis

Answer 11

fertilization increases as sperm moves along the body (corpus)

• Sperm mature and are more capable to fertilize
• lumen/diameter of duct increases which allows the flow rate to slow down at tail of epidydymys (that’s why its store bc it can last there for a month or so)

Question 12

Urinary Urgencies

Answer 12

BPh- benign hypothehic # which occur with age

Question 13

Corpora Amylacea

Answer 13

With Age, these appear in prostate

Question 14

Unique histoogical structure of bulbourethral gland

Answer 14

Skeletal muscle

Question 15

Infolding of nuclear membrane is characteristic of…

Answer 15

Sertoli Cell Nuclei

Question 16

Verumontanum

Answer 16

Large cavity in prostate. Where 2 secretory ducts in prostate empty in to, Gives orientation of prostate
