Ovarian agenesis refers to a situation where there is a congenital absence of the ovary.
Unilateral ovary agenesis affects approximately 1 in 11,240 women while bilateral agenesis is even rarer 1.
Most patients with agenesis of the ovary are asymptomatic. Ovarian torsion with subsequent necrosis and resorption antenatally is asymptomatic while in the adults and children groups, ovarian torsion is associated with severe symptoms and needs surgical emergency 2.
Clearly, it is important to establish that the patient has not had their ovary removed surgically.
It may be broadly classified as:
- unilateral ovarian agenesis
- bilateral ovarian agenesis
This condition may be the result of a congenital malformation especially when the entire ipsilateral fallopian tube is missing or ischemic events because of mechanical alterations such as torsion and subsequent resorption of the ovary during fetal life or childhood 3.
Ultrasound and MRI are useful imaging modalities and can provide a definitive diagnosis.
Treatment and prognosis
No treatment is needed if asymptomatic.
