What should I do girls?

Virginia
My boyfriend has very low testosterone. He needs to be put on hormonal therapy. He abused steroids when he was younger and now paying for the price. I know blah blah blah bad guy blah....it was a long time ago and I dealt with it. It's led him to be extremely short tempered, angry all the time, gained over 100 pounds, low energy, the whole shabam. Well I'm in a pickle of either setting him up with a male endocrinologist or a female endocrinologist. I am doing it because I'm pass the point of his anger and he works 12-15 hrs a day and can't set up the appointment. I've been looking on Google and reading the reviews. As the male doctor reviews are a 1 star out of 5 and the female doctor is 4 star out of 5. I want him to have a great doctor but not feel uncomfortable discussing this with a doctor. What should I do? Do I send him to a guy who sucks at his job or a female who is great at her job. Please be nice as this is a very touchy subject.
