Which hormones are secreted during a natural menstrual cycle?

During the menstrual cycle hormones are secreted from the hypothalamus, the pituitary and the ovaries, causing the maturation and finally the release of the egg from the ovary. These hormones interact with each other via feedback mechanisms, creating the right environment for conception to occur.

At the beginning of a natural menstrual cycle the hypothalamus-released GnRH activates another gland, the pituitary, to produce follicle stimulating hormone (FSH) and luteinizing hormone (LH). FSH promotes the growth and development of the follicles and LH is responsible for their final maturation and ovulation.
