|a2=The significance of uterine cysts is unclear, and often mares are pregnant despite having many
cysts. Cysts can give rise to false early pregnancy diagnosis or the incorrect diagnosis of twin
pregnancies during ultrasound scanning. During follow-up examinations, cysts do not increase in
diameter, are relatively constant in their position and show no appearance of an embryo around
20–23 days of pregnancy. Thorough identification of them at the beginning of the breeding season
minimises the chance of false pregnancy diagnoses. Large cysts may interfere with the mobility phase of the conceptus and make the vesicle unable to prevent luteolysis. Later in pregnancy, the absorption of nutrients and the development of chorionic villi may be diminished in places of contact between cysts and fetal membranes, leading to an increased risk of embryonic death.

|a3= The need for therapy for endometrial cysts is uncertain.
Because of risks such as uterine haemorrhage, mechanical uterine curettage is rarely used. Larger cysts can be punctured using an endometrial biopsy apparatus or manually if the cervix allows passage of one hand. Chemical curettage has equivocable results: the cysts may disappear but scar tissue may form. An endoscope and a thermocautery method involving looping and subsequent burning of cysts is possible. Wounds after cautery appear to heal very quickly. After cauterisation prostaglandin should be given and the uterus lavaged with saline.
