Hormones in Menstrual Cycle

• Oestrogen is secreted by the ovaries. It stops FSH being produced - so that only one egg matures in a cycle and it stimulates the pituitary gland to release hormone LH.
• Progesterone is a hormone secreted by ovaries. It maintains the lining of the uterus during the middle part of the menstrual cycle and during pregnancy.
• Follicle stimulating hormone (FSH) is secreted by the pituitary gland. It causes an egg to mature in an ovary and it stimulates ovaries to release hormone oestrogen
• Luteinizing hormone (LH): is also secreted by pituitary gland and causes mature egg to be released from ovary.
