### Date : 2025-02-26 13:30 ---- ## **Female Hyperandrogenism – In-Depth Study** ### **1. What is Female Hyperandrogenism?** **Female hyperandrogenism** refers to a condition in which women have **excess androgens (male hormones)**, primarily **testosterone, Dihydrotestosterone (DHT), and dehydroepiandrosterone sulfate (DHEA-S)**. Androgens are essential for **normal female physiology**, but when levels become too high, they can cause **masculinizing effects** such as: ✔ **Excessive hair growth (hirsutism)** ✔ **Male-pattern hair loss (Female Androgenetic Alopecia)** ✔ **Oily skin and severe acne** ✔ **Menstrual irregularities** ✔ **Deepened voice and muscle growth (severe cases)** --- ## **2. Causes of Female Hyperandrogenism** Female hyperandrogenism can be caused by several underlying conditions, including: ### **2.1 Polycystic Ovary Syndrome (PCOS) – Most Common Cause** - **Accounts for ~80% of hyperandrogenism cases**. - **Pathophysiology**: - Insulin resistance → Increased LH (Luteinizing Hormone) → **Ovarian androgen overproduction**. - Disrupts **menstrual cycles** and leads to **ovulatory dysfunction**. - **Symptoms**: - Hirsutism (excess body hair growth, male-pattern areas like face and chest). - Androgenetic alopecia (female-pattern hair loss). - Acne, oily skin. - Irregular or absent periods. - Weight gain, insulin resistance, or prediabetes. --- ### **2.2 Congenital Adrenal Hyperplasia (CAH)** - **21-hydroxylase deficiency** → Decreased cortisol → Increased ACTH → **Excess adrenal androgen production**. - Can be **classic (severe, in infancy)** or **non-classic (milder, in adolescence/adulthood)**. - **Symptoms**: - Early puberty (in children). - Severe hirsutism and acne. - **Deepened voice** (in severe cases). - Clitoromegaly (in extreme cases). --- ### **2.3 Cushing’s Syndrome (Excess Cortisol)** - **Excess cortisol suppresses estrogen**, increasing androgenic effects. - Can be due to **pituitary adenomas (Cushing’s disease) or adrenal tumors**. - **Symptoms**: - Weight gain (moon face, truncal obesity). - Thin skin, easy bruising, purple striae. - Hirsutism and hair thinning. - **Muscle weakness**. - **High blood pressure and diabetes**. --- ### **2.4 Androgen-Secreting Tumors** - **Ovarian tumors (Sertoli-Leydig cell tumor, Thecoma, Granulosa cell tumor).** - **Adrenal tumors (Androblastoma, Adrenal adenomas).** - **Rare (~0.2% of hyperandrogenism cases), but fast progression.** - **Symptoms**: - **Rapid** onset of male-pattern baldness. - **Deepening of voice**. - **Increased muscle mass**. - **Clitoromegaly** (enlarged clitoris). 🚨 **Key Feature:** If **hyperandrogenism symptoms develop suddenly or progress rapidly**, always suspect a tumor. --- ### **2.5 Idiopathic Hyperandrogenism** - No clear underlying cause, but **testosterone levels remain elevated**. - Can be due to **genetic variations in androgen metabolism**. - Patients have **normal menstrual cycles but exhibit symptoms like mild hirsutism**. --- ## **3. Clinical Features of Female Hyperandrogenism** |**Symptoms**|**Description**| |---|---| |**Hirsutism**|Male-pattern hair growth (face, chest, abdomen, back).| |**Androgenetic Alopecia**|Female-pattern hair loss (central scalp thinning, widened midline).| |**Acne & Oily Skin**|Due to increased sebum production.| |**Menstrual Irregularities**|Oligomenorrhea (infrequent periods) or amenorrhea (absent periods).| |**Voice Deepening**|More common in adrenal/ovarian tumors.| |**Clitoromegaly**|Severe sign, usually seen in adrenal hyperplasia or androgen-secreting tumors.| |**Increased Muscle Mass**|Seen in severe cases (Cushing’s or androgen-secreting tumors).| --- ## **4. Diagnostic Approach to Female Hyperandrogenism** ### **4.1 Clinical Evaluation** - **History**: - **Age of onset** (Gradual = PCOS, Rapid = Tumor). - **Menstrual history** (Irregular = PCOS, Normal = Idiopathic). - **Hair loss/hirsutism progression** (Mild vs. severe). - **Physical Examination**: - **Ferriman-Gallwey Score** (Hirsutism assessment). - **Hair thinning pattern** (Ludwig scale for female-pattern hair loss). - **Signs of virilization** (Deep voice, muscle hypertrophy, enlarged clitoris). --- ### **4.2 Laboratory Tests** |**Test**|**Purpose**| |---|---| |**Total Testosterone**|Elevated in PCOS, tumors, CAH.| |**Free Testosterone**|More sensitive for hyperandrogenism.| |**DHEA-S (Dehydroepiandrosterone sulfate)**|Elevated in **adrenal causes (CAH, adrenal tumors)**.| |**LH/FSH Ratio**|**>2:1 suggests PCOS**.| |**17-Hydroxyprogesterone**|Elevated in **non-classic CAH**.| |**Cortisol**|Elevated in **Cushing’s syndrome**.| |**ACTH (Adrenocorticotropic Hormone)**|Differentiates **pituitary vs. adrenal causes**.| 🩺 **Imaging (If Tumor Suspected)** - **Pelvic Ultrasound (Ovarian tumors, PCOS diagnosis)** - **Abdominal CT/MRI (Adrenal tumors)** - **Dexamethasone Suppression Test (For Cushing’s syndrome)** --- ## **5. Treatment of Female Hyperandrogenism** ### **5.1 Treating the Underlying Cause** - **PCOS** → **Combined Oral Contraceptives (OCPs) + Spironolactone**. - **Congenital Adrenal Hyperplasia** → **Glucocorticoids (Hydrocortisone, Prednisolone)**. - **Cushing’s Syndrome** → **Surgical removal of tumor** (if present). - **Androgen-secreting Tumors** → **Surgical excision**. - **Idiopathic Hyperandrogenism** → **Symptomatic management**. --- ### **5.2 Medications for Symptom Control** #### **1️⃣ Anti-Androgens (To Reduce Hair Loss & Hirsutism)** - **Spironolactone (50-200mg/day)** - **Blocks DHT binding to androgen receptors**. - Used with OCPs to **prevent menstrual irregularities**. - **Side effects**: Breast tenderness, hyperkalemia. - **Finasteride (5α-Reductase Inhibitor)** - Blocks DHT production. - Used for **female pattern hair loss**. - **Not used in pregnancy** (risk of fetal abnormalities). - **Flutamide (Androgen Receptor Blocker)** - Used in severe hirsutism. - **Hepatotoxic** → Not commonly used. --- #### **2️⃣ Oral Contraceptives (For PCOS and Hormonal Regulation)** - **Estrogen-Progestin OCPs (e.g., Ethinyl Estradiol + Drospirenone)** - Suppresses ovarian androgens. - Regulates periods and reduces acne. --- ### **5.3 Cosmetic Treatments for Hair & Skin** - **Hair Loss (Androgenetic Alopecia)** - **Minoxidil (2% or 5%)** → Increases hair growth. - **PRP Therapy** → Growth factors stimulate follicles. - **Hair Transplant or SMP** → For advanced hair loss. - **Hirsutism (Unwanted Hair)** - **Laser Hair Removal** (Long-term solution). - **Electrolysis** (For permanent results). - **Topical Eflornithine (Vaniqa Cream)** → Slows hair growth. --- ## **Conclusion** Female hyperandrogenism is a **hormonally driven condition** with multiple causes. 📌 **PCOS is the most common cause**. 📌 **DHT and androgens trigger hair loss and hirsutism**. 📌 **Early diagnosis and hormonal therapy** can **prevent progression**.
