Answer:
Menstrual cycle is rhythmic reproductive cycle in which the endometrium wall of uterus forms placenta. Placenta provides nourishment to the developing fetus if implantation occurs. If pregnancy does not occur, this endometrial lining is shred off, known as menstruation. So, this endometrium thickening is not permanent.
