**Core Concept**
Turner syndrome is a genetic disorder that affects females, characterized by the partial or complete absence of one X chromosome. This condition leads to various physical and developmental abnormalities, primarily due to the loss of one sex chromosome.
**Why the Correct Answer is Right**
Turner syndrome is associated with short stature, ovarian dysgenesis, and infertility. The lack of one X chromosome disrupts the normal development of ovarian follicles, leading to premature ovarian failure. Additionally, individuals with Turner syndrome often have characteristic physical features, including a short neck, webbed neck, and low-set ears. The syndrome is also associated with cardiovascular abnormalities, such as bicuspid aortic valve and coarctation of the aorta.
**Why Each Wrong Option is Incorrect**
**Option A:** Short stature is a feature of Turner syndrome, so this option is incorrect.
**Option B:** Ovarian dysgenesis is a hallmark of Turner syndrome, making this option incorrect.
**Option C:** Infertility is a common consequence of Turner syndrome due to ovarian dysfunction, so this option is also incorrect.
**Option D:** **Bilateral renal agenesis** is a rare congenital anomaly, but it is not typically associated with Turner syndrome. This makes option D the correct answer.
**Clinical Pearl / High-Yield Fact**
Turner syndrome is often associated with other genetic abnormalities, such as mosaic Turner syndrome, which can affect up to 1% of the population.
**Correct Answer: D. Bilateral renal agenesis.**
