Which hormone is known to cause hirsutism?

Hirsutism is characterized by excessive hair growth in areas typically associated with male-pattern hair distribution due to an imbalance of androgens, which are male hormones. The correct hormone related to the development of hirsutism is a group of androgens, and one of the key hormones that can influence these levels is luteinizing hormone (LH).

LH plays a vital role in stimulating the ovaries to produce hormones, including testosterone, which is an androgen. Elevated levels of androgens, including testosterone, can lead to hirsutism in women. While estrogen, progesterone, and follicle-stimulating hormone (FSH) have important roles in the menstrual cycle and reproductive health, they do not directly cause hirsutism. Instead, they are involved in regulating other aspects of the reproductive system and do not promote the male-pattern hair growth that characterizes hirsutism.

In summary, LH's role in stimulating the ovaries to produce androgens, which are responsible for hirsutism, positions it as the hormone most specifically linked to this condition.
