Answer 1

Ovulation is the process that occurs in female, in which when a mature egg is released from the ovary of the female, the egg moves from the ovary and reaches to the fallopian tube, where the egg is fertilized by the male gamete cell called sperm.

Complete answer: Ovulation is a monthly occurring process that occurs under the influence of the female sex hormone known as luteinizing hormone. In the case of induced ovulation, the ovulation is triggered by the LH from the anterior pituitary which is induced during the mating process. The higher level of LH is produced by mating with multiple times. Examples of the induced ovulation squirrels and mole rats. Reflex ovulatory lacks oestrous cycles. External stimulus is necessary for ovulation, which is occurred by the mating process.
-Oxytocin is the hormone that is released by the posterior pituitary gland, which is also called a labor hormone, it helps to provide the birth of a child. Oxytocin contract the uterus to speed up the delivery process and also induce lactation in the female.
-Prolactin is a hormone that is produced by the pituitary gland, that causes the breast to grow and develop and induces the formation of milk after the birth of the baby.
