“The corpus luteum is one of the most vascular organs of the body. If animals are non–pregnant it is corpus luteum spurium and is destined to regress. If animal is pregnant, it is corpus luteum verum and corpus luteum is continues to function”

“In cow and buffalo, ovulation occurs after the end of estrus period and in Female dog, mare, sow before the end of estrus period”

Formation of Haploid ovum Formation of haploid ovum in ovary by meiosis is called as oogenesis. During prenatal period, mitotic proliferation of primordial germ cells occurs. This ends at the time of birth. Oogonia undergo mitotic division until the final generation of oogonia enters the prophase of meiosis-I. At this point it is called primary oocyte.

“Functions of the ovarian follicle and functions of the ovarian fluid are very vast”

“In sheep, cattle and horses two to three follicular waves occur during luteal phase with the last wave ending in ovulation”

“When the follicle reaches its maximum size, FSH induces LH receptors in the granulosa cells. When LH surge occurs, LH stimulates the granulosa cells to synthesize progesterone”

“Vestibular glands of animals are sebaceous and Bartholin glands. It resemble bulbo-urethral glands in the male and secrete lubricating mucus”

“Fluids exude from the vascular supply although no secretory glands present in the vagina of animals. Along with cervical mucus buffer the pH of vagina”

“Epithelial lining is present in cervix part of female reproductive system. these lining have Columnar cells and goblet cells that secrete mucus. Physical and chemical properties of the mucus change during different phases of the estrous cycle and Progesterone reduces it”

“At the end of gestation progesterone levels decrease and estrogens increase which causes uterine contractions that help in parturition”
