Endometrial atrophy consists of thinning of the endometrium. The endometrium becomes thinner and more fragile. This usually occurs once menopause is reached as a result of a decrease in estrogen levels in women.
However, the onset of menopause is not the only cause of endometrial atrophy. Some patients may also have a thin endometrium due to medical induction or the presence of certain pathologies such as polycystic ovarian syndrome, pituitary alterations, etc.
One of the problems that can be caused by endometrial atrophy is the difficulty in achieving pregnancy in women of childbearing potential. This is due to the fact that if the endometrium does not acquire adequate thickness, the embryo will not be able to implant and, therefore, gestation will not take place.
