20
Q

testosterone (androgen) is what kind of hormon

A

steroid hormone (C19)

21
Q

testosterone produced by

A

Leydig cells; and small extent by female follicle

22
Q

testosterone function

A

promotes masculinization
induces male behavior
stimulates spermatogenesis (sertoli cells)
decreases LH output

23
Q

Estrogen is what kind of hormone

A

steroid (C18)

24
Q

estrogen produced by

A

maturing follicle

25
Q

estrogen function

A

changes in tract and whole animal associated with estrus

26
Q

inhibin is what kind of hormon

A

protein

27
Q

inhibin produced by

A

granulosa cells of the follicle; sertoli cells of the testis by maturing spermatogenic cells

28
Q

inhibin function

A

shut down FSH production by te pituitary

29
Q

Anti-Mullerian Hromone is what kind of hormone

A

protein hormone

30
Q

AMH produced by

A

male embryo sertoli cells; female granulosa cells during follicle growth from primary to early antral stage

31
Q

AMH function

A

males: cause embryological female tract to regress

32
Q

AMH can be used to evaluate

A

activity of sertoli and granulosa cells
diagnosis of cryptorchidism and granulosa cell tumor
estimate the size of growing follicle pool (follicle population)

33
Q

relaxin is what kind of hormone

A

protein

34
Q

relaxin produced by

A

CL and/or placenta depending on species

35
Q

relaxin function

A

relaxation of cervix and pelvic ligaments at parturition, affects vascular development of uterus/placenta

36
Q

human chorionic gonadotropin (hCG) produced by

A

human trophoblasts (8 days after conception)

37
Q

hCG function

A

Induce LH effects (similar structure to LH but different CHO attached)

38
Q

Equine chorionic gonadotropin (eCG) produced by

A

equine trophoblast after 37 days gestation

39
Q

equine chorionic gonadotropin function

A

luteinization/ovulation of secondary follicles during pregnancy in the mare to maintain high progesterone concentration (prolonged FSH activity in other species except horse) (similar to LH)

40
Q

placental lactogens work via

A

prolactin receptors, but with lower affinity

41
Q

progstins

A

hormones that have progesterone-like effect

42
Q

prostaglandin F2a is what kind of hormone

A

long chain fatty aicd

43
Q

PGF2A is released by

A

uterus in domestic large animal species

44
Q

PGF2a function

A

lysis of the CL and uterine contraction

45
Q

androgen binding protein serves as

A

a carrier for androgens to keep concentrations of androgens relatively stable in ST and very high in relation to concentrations of androgens in the blood

46
Q

androgen binding protein produced by

A

interstitial cells
