Low testosterone

My hubby found out today that he has incredibly low testosterone levels. It was 118 to be exact.

His doctor wants him come in and talk about injections. Has anyone elses husbands had levels this low, or low at all?? Does anynone have husbands who take the injections??

If so has anything changed about them? Personality, motility etc?

UPDATE: He started TRT and im hoping it helps. But im kinda squeamish about the fact I have to give him shots at home.
