Endometriosis is a medical condition in which tissue similar to the lining of the uterus (endometrium) grows outside the uterus in places where it does not belong. These growths, called endometriosis implants, are most commonly found on the ovaries, fallopian tubes, the outer surface of the uterus, and the pelvic lining.
This condition is closely associated with an elevated risk of infertility or challenges in becoming pregnant, affecting up to 30–50% of women with the condition. Research has demonstrated that the severity and extent of endometriosis observed during laparoscopy significantly predict future fertility outcomes. Advanced cases with widespread endometriosis lesions or adhesions may have a more pronounced impact on reproductive health.
