Hcg injections

Hi everyone! My husband has just started hcg injections 3 times a week over the next 3 months to hopefully improve very low sperm count/low testosterone

We have never heard of this being an option to treat this sort of thing, we would love to hear from any other couples that have also used these injections and how it worked out for them??

Side effects, did it work etc??

Thanks 😊
