Polycystic Ovaries and Stromal Hyperthecosis 1. Polycystic Ovaries:  Definition: Polycystic ovaries are characterized by the presence of multiple small cysts on the ovaries, often associated with polycystic ovary syndrome (PCOS). The condition involves an imbalance in reproductive hormones that leads to the development of numerous fluid-filled sacs (cysts) on the ovaries.  Etiology: The exact cause of polycystic ovaries is not well understood, but it is associated with hormonal imbalances, particularly elevated levels of androgens (male hormones) and insulin resistance. Genetic predisposition may also play a role.  Clinical Presentation: Women with polycystic ovaries may present with:  o Irregular Menstrual Cycles: Infrequent or absent menstrual periods. o Oligo- or Anovulation: Reduced or absent ovulation, leading to infertility. o Hyperandrogenism: Symptoms such as hirsutism (excessive hair growth), acne, and alopecia (hair loss). o Polycystic Ovaries: On ultrasound, the ovaries appear enlarged with a thickened outer layer and multiple small cysts. Diagnosis: Diagnosis of polycystic ovaries typically involves:  o Ultrasound: The primary imaging modality for identifying multiple cysts on the ovaries. o Hormonal Assessment: Measurement of serum levels of androgens, luteinizing hormone (LH), and follicle-stimulating hormone (FSH) can support the diagnosis. o Clinical Criteria: Diagnosis often follows the Rotterdam criteria, which require two of the following: irregular menstrual cycles, clinical or biochemical signs of hyperandrogenism, and polycystic ovaries on ultrasound. Management: Treatment focuses on managing symptoms and may include: o Lifestyle Modifications: Weight loss and exercise can help improve insulin sensitivity and reduce symptoms. o Medications: Hormonal contraceptives (e.g., birth control pills) to regulate menstrual cycles and manage hyperandrogenism. Metformin may be used to improve insulin resistance. Antiandrogens (e.g., spironolactone) can help with hirsutism. 2. Stromal Hyperthecosis:  Definition: Stromal hyperthecosis is a condition characterized by hyperplasia of the ovarian stroma (connective tissue) and excessive production of androgens. It is considered a more severe form of hyperandrogenism compared to typical PCOS.  Etiology: The exact cause of stromal hyperthecosis is unclear, but it is associated with excessive androgen production by the ovarian stroma. It can be idiopathic or related to underlying hormonal imbalances.  Clinical Presentation: Women with stromal hyperthecosis may present with: o Severe Hyperandrogenism: Prominent symptoms such as hirsutism, severe acne, and male-pattern baldness. o Irregular Menstrual Cycles: Similar to PCOS, affected individuals may have irregular or absent menstrual periods. o Enlarged Ovaries: On ultrasound, the ovaries may appear enlarged with a more pronounced stroma compared to PCOS.   Diagnosis: Diagnosis involves: o Ultrasound: Imaging may show enlarged ovaries with a more pronounced stroma compared to polycystic ovaries. o Hormonal Assessment: Elevated serum levels of androgens and suppressed levels of FSH can indicate hyperthecosis. o Histopathology: In some cases, ovarian tissue may be examined to confirm hyperthecosis. Management: Treatment is aimed at managing symptoms and may include: o Medications: Anti-androgens (e.g., spironolactone) to address hyperandrogenic symptoms. Hormonal contraceptives can regulate menstrual cycles and reduce androgen levels. o Lifestyle Modifications: Weight management and exercise to improve insulin sensitivity and overall health. Conclusion: Polycystic ovaries and stromal hyperthecosis are related conditions involving ovarian dysfunction and hormonal imbalances. Polycystic ovaries are common and associated with PCOS, while stromal hyperthecosis represents a more severe form of androgen excess. Proper diagnosis through imaging and hormonal assessments is essential for effective management, which often involves a combination of lifestyle changes and medical treatments to address symptoms and underlying hormonal imbalances.
