The Role of Reproductive Hormones in Postpartum Depression
Unlike plant hormones, animal hormones are often (though not always) produced in specialized hormone-synthesizing glands (shown below). The hormones are then secreted from the glands into the blood stream, where they are transported throughout the body. There are many glands and hormones in different animal species, and we will focus on just a small collection of them.

hormones that control the reproductive function of the cow, such as prostaglandin. • Ovary – The ovary is an oval structure adjacent to each the uterine horn. Its primary function is to produce the egg, which is originated from blister-like structures called follicles. The ovary also produces hormones that control reproduction in the cow, such as estrogen and progesterone. • Oviducts
sex hormones are controlled by secretions of the anterior pituitary gland. Both the male and female sex hormones produce marked effects on the reproductive organs and on the reproductive behavior of animals.
The human male and female reproductive cycles are controlled by the interaction of hormones from the hypothalamus and anterior pituitary with hormones from reproductive tissues and organs. When the reproductive hormone is required, the hypothalamus sends a gonadotropin-releasing hormone (GnRH) to the anterior pituitary.
