**Core Concept**
Hypergonadotropic hypogonadism is a condition characterized by high levels of gonadotropins (LH and FSH) due to primary gonadal failure. This results in inadequate production of sex hormones, leading to symptoms of hypogonadism. The primary cause is usually a problem with the gonads themselves, such as in cases of Klinefelter syndrome or ovarian failure.

**Why the Correct Answer is Right**
In hypergonadotropic hypogonadism, the pituitary gland attempts to compensate for the inadequate sex hormone production by releasing more LH and FSH. As a result, FSH levels are elevated. This is because the negative feedback mechanism from sex hormones (estrogen and testosterone) is disrupted, allowing the hypothalamic-pituitary-gonadal axis to become hyperactive. The increased FSH secretion is a direct response to the decreased sex hormone production, attempting to stimulate the gonads to produce more hormones.

**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect because it does not accurately reflect the hormonal imbalance in hypergonadotropic hypogonadism. Typically, FSH levels are elevated, not decreased.
**Option B:** Incorrect because it is a characteristic of hypogonadotropic hypogonadism, where FSH levels are low due to inadequate gonadotropin secretion.
**Option C:** Incorrect because it is not a specific or accurate description of the FSH level in hypergonadotropic hypogonadism.

**Clinical Pearl / High-Yield Fact**
In hypergonadotropic hypogonadism, the elevated FSH level can be used as a diagnostic marker to differentiate it from hypogonadotropic hypogonadism. This is an important point to remember when evaluating patients with symptoms of hypogonadism.

**Correct Answer:** C. Elevated
