Z90.721
Acquired absence of ovaries, unilateral
Clinical Classification Guidelines
Medical Intelligence & Overview
Unilateral ovarian absence refers to the condition where one of the ovaries is missing or has been removed. This can occur due to various reasons, including surgical procedures or developmental issues. The condition is classified under ICD-10 code Z90.721 and is generally identified during medical evaluations such as ultrasound or surgical reports. While it may not cause significant health problems on its own, understanding the implications is important for reproductive health and overall well-being.
Causes & Symptoms
Clinical Causes: Surgical removal of one ovary due to ovarian cysts, tumors, or endometriosis Congenital absence, present from birth due to developmental abnormalities Ovarian torsion leading to necrosis and subsequent removal Injury or trauma resulting in ovarian destruction Infections that cause damage to ovarian tissue
Key Symptoms: Often no specific symptoms related directly to the absence of one ovary Potential issues with fertility, especially if the remaining ovary is also compromised Menstrual cycle may be normal if the other ovary is functioning properly In some cases, pelvic pain if associated with surgery or other underlying conditions
Diagnostic & Treatment
Diagnosis Path: Diagnosis of unilateral ovarian absence usually involves imaging studies such as ultrasound, MRI, or CT scans. These tools help visualize the ovaries and confirm the absence of one. Medical history, including previous surgeries or medical conditions, also contributes to diagnosis. Sometimes, laparoscopy is performed to directly observe the internal pelvic organs and verify the condition.
Treatment Protocols: In cases where the ovarian absence is due to surgical removal, no further treatment may be necessary unless reproductive planning is involved. Healthcare providers may discuss fertility options or hormonal management if needed. Regular gynecological check-ups are recommended to monitor overall reproductive health, especially if the remaining ovary has other issues. In situations where ovarian function is affected, hormone therapy may be considered to address hormonal imbalances or menstrual irregularities.
