Patient's question:
Hello, I would like to ask what is the meaning of the proliferative phase endometrium, and what are the hormones that transform it into the secretory phase.Doctor's answer:
With the changes in the ovaries, the endometrium is also affected and undergoes corresponding cyclical changes. Estrogen causes the endometrium to thicken, with an increase in the number and size of endometrial cells, and the small arteries in the stroma become increasingly tortuous, forming a spiral shape, known as the proliferative phase endometrium. After ovulation, due to the combined action of estrogen and progesterone, the endometrium becomes edematous, and the glands produce a large amount of mucus and glycogen, with the thickness of the endometrium increasing from 1 millimeter to 6 millimeters, known as the secretory phase endometrium.
