|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.
