Klinefelter syndrome fertility counselling — SCE Endocrinology MCQ

Correct answer: A — Early fertility and sperm-retrieval counselling integrated with testosterone planning

The best answer is “Early fertility and sperm-retrieval counselling integrated with testosterone planning”. Klinefelter syndrome causes seminiferous-tubule failure, but selected patients have focal spermatogenesis amenable to specialist retrieval; fertility goals should therefore be discussed before treatment decisions that may affect sampling. “Promise that gonadotropin injections will reliably restore spermatogenesis” is less appropriate because primary testicular failure does not reliably respond to gonadotropins as congenital hypogonadotropic hypogonadism does “Withhold fertility referral until azoospermia has persisted for ten years” is less appropriate because earlier counselling preserves options and informed timing “Avoid testosterone because gynaecomastia proves adequate androgen action” is less appropriate because gynaecomastia does not demonstrate adequate androgen replacement or bone protection “Use cabergoline if hyperprolactinaemia is suppressing gonadotropins” is less appropriate because cabergoline treats hyperprolactinaemia and has no role in this karyotypic testicular failure
