Ruling 916
The adhan and iqamah of congregational prayers must be said by a man. However, in congregational prayers of women, if a woman says adhan and iqamah, it is sufficient. Sufficing with the adhan and iqamah said by a woman in a congregational prayer in which the men present are her maḥram is problematic [i.e. based on obligatory precaution, it does not suffice].
