Question

Enumerate the etiology of Hirsutism.

Hint:

Polycystic ovary syndrome (PCOS) is the most common cause of hirsutism, often associated with irregular periods and infertility.

Answer 1

Step 1: Introduction to the Etiology of Hirsutism.
Hirsutism is commonly caused by an excess of androgens (male hormones) or an increased sensitivity of hair follicles to these hormones. Several conditions and factors can contribute to hirsutism.
Step 2: Etiology of Hirsutism.
The major causes of hirsutism include:
(1) Polycystic Ovary Syndrome (PCOS):
- The most common cause of hirsutism, characterized by elevated levels of androgens (testosterone) and irregular menstrual cycles.
(2) Congenital Adrenal Hyperplasia (CAH):
- A genetic disorder leading to adrenal gland dysfunction and excess androgen production.
(3) Cushing's Syndrome:
- Overproduction of cortisol by the adrenal glands can lead to increased androgen production and hirsutism.
(4) Androgen-secreting Tumors:
- Ovarian or adrenal tumors that secrete excess androgens, leading to hirsutism.
(5) Medications:
- Certain medications such as anabolic steroids, progestins, and minoxidil can induce hirsutism as a side effect.
(6) Idiopathic Hirsutism:
- In some women, hirsutism occurs without an identifiable underlying condition or hormonal imbalance.
