See Endocrinologist: You may have a genetic/chromosomal issue causing your symptoms. Get a check up by an endocrinologist for an eval as certain conditions such as "kleinfelters" (an extra x chromosome) for example may produce those symptoms. Best wishes.

Side effects of meds: If you have been taking Omeprazole regularly then the gynecomastia, smaller testis, tiredness may be secondary to the medication. Talk to your primary care and he/she can change the medication and that may help reverse the side effects.
