Hello 👋 sometimes we need to be careful about putting conditions in exact boxes: sometimes they don't fit neatly! 😀 This question asks "what is the most *likely*" so does require a little bit of clinical judgement. It's not outside the realm of possibility in the clinic that his blood work does fit perfectly in the box, but the low testosterone remains the most probable answer in terms of which condition is most likely to occur.
