Etiological and associated factors of thin endometrium among infertile women.

Thin endometrium is a condition that adversely affects infertility treatment outcomes by impairing embryo implantation and pregnancy success. Therefore, it is of interest to assess the etiological and associated factors of thin endometrium in 61 women undergoing infertility treatment. Thin endometrium was defined as ≤7 mm on transvaginal ultrasound. Tuberculosis was the most common cause (18 cases), followed by repeated curettage (12 cases), while 26 cases were unexplained. Advancing age (45.9%) and parity (22.9%) were the most common associated factors. Thus, we show that tuberculosis and endometrial trauma as major contributors to thin endometrium.
