According to Ferriman-Gallwey scoring system — hirsutism is diagnosed when score is more than:

**Core Concept**
The Ferriman-Gallwey scoring system is a clinical tool used to assess and quantify hirsutism in women. It evaluates the severity of excessive hair growth in nine body areas. This system helps clinicians diagnose polycystic ovary syndrome (PCOS) and other endocrine disorders.

**Why the Correct Answer is Right**
The Ferriman-Gallwey scoring system assigns a score of 0 to 4 for each body area, with a total possible score of 36. A score of 8 or more is generally considered indicative of hirsutism. This threshold helps differentiate between normal and abnormal hair growth patterns. The system takes into account the presence and severity of excessive hair growth on the face, chest, back, and other areas.

**Why Each Wrong Option is Incorrect**
**Option A:** A score of 0-7 would not be considered indicative of hirsutism, as it falls below the established threshold.
**Option B:** A score of 9-12 might suggest mild to moderate hirsutism, but it is not the correct threshold for diagnosing hirsutism according to the Ferriman-Gallwey scoring system.
**Option C:** A score of 13-15 would indicate moderate to severe hirsutism, but it is not the correct threshold for diagnosing hirsutism.

**Clinical Pearl / High-Yield Fact**
The Ferriman-Gallwey scoring system is a useful tool for clinicians, but it should be used in conjunction with other diagnostic criteria, such as laboratory tests and medical history, to confirm a diagnosis of hirsutism or PCOS.

**Correct Answer: C. 8**
