My husband has been 😢 crying

Hi! Last month my husband was diagnosed with low sperm. He has been taking fish oil, folic acid, a medicine called prosgutt to eliminate a bacteria from the urethra, centrum vitamins and his medicine for blood pressure. Lately he has been acting weird, he is very tired and sad and he cries a lot!! 😱🤭 i feel he is depressed and sentimental and he says he is not like that, he is even having trouble in his work because he can’t concentrate.

Do you think it’s the medicines? has anyone experience this?
