Husband on testosterone.

Any other couples trying or did conceive when their husband is on testosterone supplements? He went to the dr and had his levels tested. After 2 blood tests they came back low so his dr decided to do shots. He’s been on them for a little over a month. We decided to start trying in about 6 months. After talking with a dr I work with he said that we either start now or we may not be able to get pregnant. Question, has anyone else had this problem and been able to conceive? I’m terrified that it may not happen.
