Usually all doctors consult patients of either sex. You should go ahead and consult the endocrinologist. However if you have the option, you can inform the hospital OPD beforehand about your prime reason for the consultation so they can speak to the doctor before confirming the appointment.

Doctor are having specialisation for both gender except gynaecologist. You can consult her.
