Physiology of the Queen as an Induced ovulator

Estrogen FSH Proestrus Gn. RH FSH Spontaneous follicular growth Proestrus, Estrus

Feline without induced ovulation No neural Follicular response Ooocyte atresia degeneration No vaginal stimulation

Interestrus 1 -10 days Inactive ovaries

Estrous Cycle(s) of the Queen Pro/Estrus No Ovulation Interestrus

Insufficient vaginal stimulation results in insufficient LH to cause ovulation and results in the queen entering: Anestrus or interestus

Estrogen FSH Proestrus Gn. RH FSH Spontaneous follicular growth Proestrus, Estrus

Inadequate Gn. RH Feline insufficient vaginal stimulation LH LH Inadequate or short-lived LH Insufficient LH release and binding Follicular atresia Ooocyte degeneration Insufficient vaginal stimulation Vaginal stimulation

Interestrus 1 -10 days Inactive ovaries

Estrous Cycle(s) of the Queen Pro/Estrus No Ovulation Interestrus

Sufficient vaginal stimulation Results in LH queen entering Ovulation Diestrus or Corpus pseudopregnancy luteum Progesterone

Estrogen FSH Proestrus Gn. RH FSH Spontaneous follicular growth Proestrus, Estrus

Gn. RH Ovulation LH LH LH LH Corpus luteum LH LHLH LH Progesterone LH LH Induced ovulation Diestrus LH After day 3 estrus > 2 hours apart Vaginal stimulation

Diestrus or Pseudopregnancy Corpus luteum Progesterone 40 Day Duration (not like dog)

Diestrus or Pseudopregnancy After 40 days have luteal degeneration Corpus luteum Progesterone Go into anestrus or interestrus

Interestrus 10 -14 days Inactive ovaries

Estrous Cycle(s) of the Queen 10 -14 days Pro/Estrus Ov ul Interestrus at io n Diestrus 40 days
