Bismihi ta'ala
From a fiqhi perspective, a wife is able to petition for divorce, and she can forfeit her mahr and request that her husband divorces her.
However, in this specific case of the husband not able to make his wife pregnant, are there other underlying problems, or is it only this issue. If it is only this issue, what if it was the other way around, where the wife was not able to fall pregnant, would it be nice for the husband to divorce her on such grounds alone?
There might be alternative options to take, and some patience as well. Of course, if there are other problems that contribute to the wife making such a decision, then that is something else, and she should consult her family and wise people.
With prayers for your success.
