Is it possible since my husband got shot in his genitals in te military we will only have the one baby or could we have more?

See a urologist: Was he shot before or after you conceived your first child ? If before, then having one after would imply you can have more. If after, it depends on what structures remain in working order. A visit to a urologist could sort out the issue for your husband & open discussion on how you might use assisted technology to work around an injury.

Depends: This depends on the trauma he sustained. If he has at least one functioning testis then there is hope -- even with severed connection to seminal vesical (vas deferens injury). If he is still active duty, he should enquire at naval medical center san diego as one of the urologists there specializes in repairing anatomic lesions and male fertility.

Possible: It is possible, as long as he has retained at least one functioning testicle. The testicles are responsible for the production of sperm. I recommend that you see a urologist for a full evaluation.
