Q

What are the phases of spermiogENESIS?

A

Phase 1: Spermatogonial
Proliferation, renewal and differentiation of spermatogonia (MITOSIS)

Phase 2: Spermatocyte

2 MEIOSIS

Phase 3: Spermatid (spermiogenesis)

Spermatids metamorphose into spermatozoa

Q

What are the main characteristics of spermatogenesis?

A
  • Duration: 60 days (fixed and constant)
  • Stem cells enter spermatogenesis everey 16 days
  • Stem cells enter spermatogenesis in groups connected by intercellular bridges
  • It is HIGHLY sensitive to toxic factors such as drugs, radiation and temperature

Q

What are the roles of Sertoli cells?

A
  1. Supporting cells at the basement membrane
  2. Promote the growth of sperms
  3. Exhibit phagocytic function: helps to eliminate the residual bodies discarded by the maturing spermatids
  4. Secrete luminal fluids
  5. Produce anti-Müllerian hormone (AMH) and Inhibit (supresses FSH)
  6. Formation of blood-testis barrier (tight junction, immuno-privelidged site)

Q
A

A. Dark spermatogonium

20
Q
A

A. Round spermatids

21
Q
A

E - estrogen

22
Q
A

E. Primary Multilaminar Follicle

23
Q
A

A - basophil

24
Q

Inactivation of the estrogen receptor α-gene (ERKO) can cause what?

A

Infertility in males because it regulates the these pores and channels in the ductuli efferentes.

25
Q
A

A. Primary spermatocyte

26
Q
A

A - mammary alveolus

27
Q

What is the function of the epididymis?

A

To bring testicular spermatozoa to maturity because testicular spermatozoa are non-motile and incapable of fertilization

28
Q

Where can you find Herring body?

A

In the posterior (neurohypophysis) pituitary

29
Q
A

A - chromophil

30
Q

What is the primary function of interstitial (Leydig) cells?

A

Produce testosterone:

  1. Embryo development of male fetus
  2. Initiation and maintenance of spermatozoa production
  3. Development of accessory organs and secondary sex characteristics
  4. Secretion of accessory glands
31
Q
A

C - chromophobes and chromophils

32
Q
A

C. Cumulus Oophorus

33
Q
A

C. Primary Oocyte

34
Q

What do the basophils cells produce?

A
  • ACTH
  • TSH
  • FSH
  • LH
35
Q

What is the excretory duct path?

A

Rete testis –> ductuli efferentes –> head, body then tail of epidimymis –> vas deferens –> urethra –> out

36
Q
A

E. Steroli Cells

37
Q
A

E - posterior lobe

38
Q

What are the types of Spermatogenic cells?

A
  1. Spermatogonia (basement membrane)
  2. Spermatocytes
  3. Spermatids (adluminal region)
39
Q

What is Immotile cilia syndrome?

A

A cause of infertility. It is caused by mutations in the dynein gene and in other genes encoding proteins required for flagellar and ciliar motility. This disorder is associated with chronic respiratory infections due to impaired motility of the cilia of the respiratory epithelium

40
Q
A

A. Cervix and Vagina (fornix)

41
Q
A

E - folliculistellate

42
Q
A

B. Cervical Canal

43
Q
A

E. Transformed granulosa cells

44
Q
A

B. Myoid cell

45
Q
A

B. Contains ciliated cells
