Is It Low T?

I got some test results (see below). My doctor said I'm low T and wants to start treatment.
I'm 46 years old (Asian male). is this normal #?
If I need to go treatment, should injection be better? this is because I have you kids and wife and don't want any accidents of transferring.

Yes, your levels are very low.
Injections are the most efficient in terms of effectiveness and success. Gels and creams can work well too but do not for some men.
