Testoserone Shots=Zero Sperm

About a month and a half ago my husband did a SA. The results came back with a zero sperm count. We went to see a fertility specialist urologist for it, and he said it was 100% related to the testosterone shots. He was proscribed Chlomid, and he said within 3 to 6 months, off of the shots, his sperm should be back. The Dr. said he sees this all the time with his patients on testosterone. If anyone of you have husbands on the shots, have them stop as soon as possible!
