heyArchie, do u remember choices.
We are so trained having choices its little bit difficult to think without it.

It may be due to pituitary tumor, e.g. prolactinoma. Prolactin causes gynecomastia and damage of pituitary tissue causes low TSH, thus low T3 and T4.

prolactinoma --> Inhibition of Pit axis --> decr GnRH --> Small Testes
