TTC/ male Testosterones??

Ive been trying to conceive baby #2 for almost a year with no luck !!

A few people told me that if my husband was to take male Testosterones it would increase the changes. I’m a little confuse because I was reading online that Testosterones are actually not good when TTC..

Does anyone know if male Testosterones will increase our changes of getting pregnant ?

This is so discouraging!! My daughter keeps asking us for a sibling and my heart breaks every time I hear her talking about wanting a sibling 😞
