Infertility can also be caused by growths such as adenomyosis, polyps and fibroids on the reproductive organs of a woman. Adenomyosis refers to the condition when endometrial tissue grows into the muscular layer of the uterus. Non-cancerous growths that occur in the vagina, uterine lining or cervix are known as polyps. Non-cancerous tumours of varying sizes that grow in or around the uterus are called fibroids.

Spotting during sexual intercourse, heavy menstrual bleeding or irregular periods are all symptoms of adenomyosis, polyps and fibroids.
