Question

A 25-year-old man and his wife undergo an infertility workup. His wife's reproductive function is normal. On physical examination he has descended testes that appear decreased in size. A sperm count shows aspermia. A testicular biopsy is performed and on microscopic examination only Sertoli cells are present in the seminiferous tubules. Which of the following laboratory test findings is he most likely to have?​

Answer 1

Answer:

increased FSH

Explanation:

Such a 'Sertoli cell only' syndrome is a cause for male infertility and may be idiopathic. A similar pattern would be present in a cryptorchid testis.
