Husband with a zero sperm count

Hello everyone, my husband and I have been TTC for 4 years. He is 28 years old and I am 26 years old. In March 2019 my husband was tested 2 separate times and both results came back for zero sperm count. Doctors have ran several test and have done ultrasounds. Hormones and testosterone levels are normal. Genetics and DNA are normal. They don’t think he has any blockages. They have yet to be able to diagnose him with anything. The only advice they have gave us is to start looking into “other options.”

Has anyone else been through this? If so, what did you do?

Is there any hope for us? We want a baby so bad..... 😞

If anyone has any success stories, please share. I’d love to read your stories.
