Hormones and The Menstrual Cycle
Follicle-Stimulating Hormone (FSH) and Estrogen
At the beginning of your cycle a gland in your brain produces the FSH hormone, which stimulates a cluster of follicles (containing undeveloped eggs) to develop in your ovaries. These follicles release estrogen, a hormone that causes the lining of your womb to thicken.
Luteinizing Hormone (LH)
As one of the eggs develops in the ovaries, estrogen levels rise further. When they are high enough, the pituitary gland releases LH, which triggers ovulation. The follicle bursts, and the egg leaves the ovary to travel down the fallopian tubes.
The burst follicle in the ovary then produces progesterone, which transforms the womb lining in order to receive a fertilized egg. If the egg is not fertilized, progesterone levels drop, and the lining of the womb is discharged in menstruation.
