Questions and Answers

What is hyperandrogenism and how can it manifest in women?

Hyperandrogenism is the elevated level of male hormones in women, which can manifest as excess hair growth, acne, alopecia, hirsutism, and virilization.

Define hirsutism and explain its hormonal basis.

Hirsutism is excessive terminal hair growth in a male-pattern distribution caused by androgen excess affecting hair follicles.

What are the key features of virilization in women?

Virilization in women includes features such as temporal balding, deepening of the voice, enlargement of the clitoris, and loss of feminine body fat distribution.

How do androgens typically originate in women?

<p>In women, androgens are primarily produced by the ovaries and adrenal glands.</p> Signup and view all the answers

Explain the role of LH in the production of ovarian androgens.

<p>Luteinizing hormone (LH) stimulates the production of androgens in the ovaries.</p> Signup and view all the answers

What is the significance of SHBG in androgen metabolism?

<p>Sex hormone-binding globulin (SHBG) binds androgens in circulation, regulating their bioavailability by limiting the free fraction.</p> Signup and view all the answers

Describe the metabolic conversion of testosterone in target tissues.

<p>Testosterone is converted to the more potent dihydrotestosterone (DHT) in target tissues via the enzyme 5α-reductase.</p> Signup and view all the answers

What are the two categories of hyperandrogenic disorders?

<p>Hyperandrogenic disorders can be divided into nonneoplastic and neoplastic disorders of the adrenal glands or ovaries.</p> Signup and view all the answers

What is the primary method for managing hirsutism in PCOS patients?

<p>The primary method is ovarian suppression through the administration of an estrogen-progestin contraceptive.</p> Signup and view all the answers

How does estrogen in oral contraceptives affect testosterone levels?

<p>Estrogen stimulates SHBG production, which decreases free testosterone levels.</p> Signup and view all the answers

What role does spironolactone play in the treatment of hirsutism?

<p>Spironolactone acts as a peripheral antiandrogen by competing for testosterone-binding sites and decreasing testosterone production.</p> Signup and view all the answers

Why is it important to combine antiandrogen therapy with oral contraceptives?

<p>Combining them prevents conception and protects against the antiandrogen blocking normal sexual differentiation in a male fetus.</p> Signup and view all the answers

What is the expected time frame to observe cosmetic improvement in hirsutism when using spironolactone?

What type of ovarian tumors can produce androgens indirectly through surrounding stroma hyperplasia?

Define idiopathic hirsutism and its potential cause.

<p>Idiopathic hirsutism is a condition where women have mild to moderate hirsutism with normal ovarian function and androgen levels, potentially caused by increased conversion of testosterone to DHT.</p> Signup and view all the answers

How did the onset of hirsutism relate to conditions like PCOS or late-onset CAH?

<p>Hirsutism in PCOS or late-onset CAH typically begins during puberty and progresses gradually into adulthood.</p> Signup and view all the answers
