What is the cause of Hirutism?

  1. Decrease in estrogen

  2. Increase in the hormone androgen

  3. Lack of protein

  4. Exposure to sunlight

The correct answer is: Increase in the hormone androgen

Hirutism is a condition where there is excessive hair growth in women in areas such as the face, chest, and back. The most common cause of hirsutism is an increase in the hormone androgen, specifically testosterone. This can be due to conditions such as polycystic ovary syndrome (PCOS) or adrenal gland disorders. Decrease in estrogen (option A) is not a cause of hirsutism, but it can contribute to hair loss. Lack of protein (option C) does not play a role in hirsutism. Exposure to sunlight (option D) can increase vitamin D production but it is not related to hirsutism.
