Welcome to Ask The Doctor.
I understand your concern.
Lyrica contains Pregabalin which doesn't affect the sperm production. However, as far as conception safety is concerned, it's safety is doubtful. So, it should be used only in case, it's use is very necessary. So, your husband should discuss the matter with the his physician who has prescribed it.
It should be stopped, if possible.
I hope it helps.
