The endometrium is the lining of the uterus. It is one of the few organs in the human body that changes in size every month throughout a person’s fertile years. Each month, as part of the menstrual cycle, the body prepares the endometrium to host an embryo. Endometrial thickness increases and decreases during the process.
Two hormones, oestrogen and progesterone, prompt these cycles of endometrial growth and its shedding through menstruation if a pregnancy does not develop.
