Are there other forms of hypogonadotrophic hypogonadism?
Yes. Hypogonadotrophic hypogonadism (which we will shorten to HH) covers a range of rare disorders that all result in the failure to enter puberty. Kallmann’s syndrome is a specific form of HH in which the individual has no sense of smell. There are other forms of HH where the sense of smell is present but are still very similar to Kallmann’s syndrome.
