It it possible to be diagnosed with hypogonadism and adhd simultaneously?

Yes: Yep. One condition does not exclude the other. Hypogonadism is diagnosed with blood tests. There are no such tests for adhd, which is based on certain diagnostic criteria as contained in an official manual. A person could conceivably have some other hormonal disturbances causing attentional problems, such as hypothyroidism. An evaluation is needed. Good luck.

Klinefelter Syndrome: Is a chromosomal disorder from nondisjunction, an accident in formation of reproductive cells. If mom's egg with xx or dad's sperm with xy joins with the x or y from the other parent, the male child has xxy, often with some or all signs & symptoms of ks, including hypogonadism, adhd & learning disabilities from visual-perceptual deficits.
