Q: Can you check weak erection trew blood work

A. There are many, many reasons why a man can’t achieve an erection. Some are physical. Some are psychological. The place to start is with your doctor. Make an appointment to see your primary care provider and tell him or her as honestly as you can what you have been experiencing. If everything checks out physically, ask for a referral to a mental health professional to talk about it.
I wish you well.
