Overall, the purpose of the treatment improves self-identification of an individual, reduces the increased risk of cancer and reduces the possibility of infertility, if not already present. PMDS patients have a possibility of infertility in the future if not promptly operated on. When the affected males are adults, those who are not aware of the condition may find the presence of blood in their semen (hematospermia). The Müllerian structures and cryptorchidism can also  develop into cancer if ignored, or if there are pieces of Müllerian structures left from past surgery. If PMDS is found during adulthood, or if Müllerian structures had to be left behind due to risks in surgery, biopsies of the remaining Müllerian structures can be performed. Upon pathohistological observation, the endometrial tissues appear atrophied, and the fallopian tubes have begun to congest showing signs of fibrosis. Epidemiology
PMDS is a relatively rare congenital disease. From current data, approximately 45% of the known cases are caused by mutations in the AMH gene, being a mutation on chromosome 19 (Type I PMDS). Approximately, 40% are AMHR2 mutations, on the AMH receptor type 2 gene, which is on chromosome 12 (Type 2 PMDS). The remaining unknown 15% are referred to as idiopathic PMDS. Case studies
Especially before the 21st century, these conditions were hard to diagnose due to the lack of modern imaging capabilities. For this reason, the older population, or those in poorer countries found out later.
If an inflamed pinguecula is causing discomfort or cosmetic concerns, it may be treated with short course of topical steroid. Laser photocoagulation may also be used to remove pinguecula. See also
