Question 24

describe the oestrus cycle in a butch including the hormonal influence

Answer 24

GnRh is released from the hypothalamus which stimulates the anterior pituitary to produce FSH.

FSH acts on the ovary to start follicle formation. the follicle produces oestrogen which has negative feedback of FSH and promotes the release of LH.

LH surge happens and causes ovulation. CL forms and produces progesterone for 9 weeks. CL regresses, progesterone decreases and then the bitch goes into anoratrous

Question 25

explain how spermatogenesis takes place

Answer 25

GnRh is released by the hypothalamus
Gnrh stimulates the anterior pituitary gland to release LH
LH is released and acts of the cells of leading to produce testosterone
testosterone is released after a surge of LH
FSH and testosterone act on the semiferous tubules which stimulate the sertoli cells to produce oestrogen and the right nutrient filled fluid to create sperm in the spermatogenic cells
