Does any of your loved ones have Body dysmorphia disorder?

I believe My SZ son has BDD and he is completely obsessed and distraught by it ,He believes he has low testosterone and that his hair is falling out and that his testes are shrinking , its been over a year of constant urologist saying he’s ok and he doesn’t believe them .we will be seeing a new psychiatrist next week . My heart breaks for him , i was wondering if any of your loved ones have that condition too and if so do you know what can help ?
