Which of the following statements are correct about Klinefelter’...
B. Such an individual has overall masculine development. However, the feminine development is also expressed. People with Klinefelter syndrome are male (XY), but they often have certain physical characteristics that may be typically associated with female development, such as wider hips, less body hair, and sometimes breast tissue development.
E. Such individuals are sterile. Often, individuals with Klinefelter syndrome produce little to no sperm and are therefore usually infertile. However, there are cases where fertility treatments can help some men with Klinefelter syndrome to father children.
For the other options :
A. This disorder was first described by Langdon Down (1866). This is incorrect. Klinefelter's syndrome was first described by Dr. Harry Klinefelter in the 1940s, not by Langdon Down.
C. The affected individual is short statured. This is incorrect. In fact, individuals with Klinefelter's syndrome are often taller than average.
D. Physical, psychomotor and mental development is retarded. This is also incorrect. While individuals with Klinefelter syndrome may have some learning difficulties or delays, particularly with language and speech, it is not accurate or appropriate to say that their physical, psychomotor, and mental development is "retarded". They may face some challenges, but with support they can lead healthy, productive lives.

Which of the following statements are correct about Klinefelter’...
Understanding Klinefelter’s Syndrome
Klinefelter’s Syndrome is a genetic condition that affects males, caused by the presence of an extra X chromosome (47,XXY). Here's a breakdown of the statements provided in the question:
Statement A: First Described by Langdon Down
- This statement is incorrect. Klinefelter’s Syndrome was first described by Harry Klinefelter in 1942, not Langdon Down.
Statement B: Masculine Development with Feminine Traits
- This statement is correct. Individuals with Klinefelter’s Syndrome typically exhibit overall masculine development but may also express some feminine characteristics, such as breast tissue development (gynecomastia).
Statement C: Short Stature
- This statement is incorrect. Generally, individuals with Klinefelter’s Syndrome are not necessarily short. In fact, they may be taller than average due to delayed growth plate closure.
Statement D: Retarded Development
- This statement is somewhat misleading. While affected individuals may experience learning difficulties or delayed speech and language skills, they often have normal or above-average intelligence. Therefore, this statement is not entirely accurate.
Statement E: Sterility
- This statement is correct. Most individuals with Klinefelter’s Syndrome are sterile due to abnormal testicular development, which leads to reduced testosterone levels and impaired sperm production.
Conclusion
Based on the analysis:
- The correct statements are B and E. Thus, option 'C' (B and E only) is the correct answer.
Klinefelter’s Syndrome presents a unique combination of characteristics that can impact physical appearance, reproductive capability, and, in some cases, cognitive function.
