Which of the following is a cause of hirsutism?

Hirsutism is characterized by excessive hair growth in women in areas where males typically grow hair. It often results from hormonal imbalances, particularly an increase in androgens, which are male hormones present in both men and women.

The third option—pituitary hypersecretion, adrenal tumors, and ovarian tumors—highlights conditions that can significantly elevate androgen levels in the body. For example, an adrenal tumor can directly produce androgens, leading to the symptoms of hirsutism. Similarly, ovarian tumors that secrete hormones can disrupt normal hormonal balance, resulting in excessive hair growth. Pituitary gland issues can also increase the production of various hormones that influence adrenal and ovarian function, further contributing to hirsutism.

The other options do not directly relate to the excessive production of androgens needed to cause hirsutism. Low blood sugar levels and excessive exercise are associated with other health conditions that do not typically lead to the hormonal changes responsible for the growth of excess body hair. Although underlying thyroid issues can impact overall hormonal balance, they are more often linked with symptoms like weight changes, fatigue, and temperature regulation rather than directly causing hirsutism. Thus, the correct choice reflects a clear connection to the hormonal causes
