You are assessing a patient who presented with intersex genitalia. You find that this individual is genetically male (has one X chromosome and one Y chromosome) and possesses the testis-determining factor (called the SRY gene). Further, they are producing adequate levels of gonadotropin-releasing hormone, follicle-stimulating hormone, and testosterone. What is the most likely explanation for this individual’s intersex genitalia? A.absent or inactive testosterone receptors B.hyposecretion at the level of the hypothalamus C. hyposecretion at the level of the testes D....
