Hormones are natural substances produced in the body. Hormones act as “messengers” around the body, which travel through the blood stream and cause physical and chemical functions and processes within the body to occur.
When it comes to understanding the female reproductive system, the ovaries and pituitary gland play major roles. The ovaries make most of the estrogen and progesterone in the female body. Estrogen and progesterone are the two key hormones that control the reproductive system and hence a woman’s fertility. The pituitary gland uses hormones to send signals to the ovaries to trigger events. Once triggered, the body returns feedback to the pituitary to help the brain regulate these events by either reducing or increasing the amount that hormone being released.
