Must we interview both men and women when we have a specific gender in mind to fill the vacancy?

Q: We are looking to replace our front-desk receptionist, who gave us her two-week notice. We advertised for the opening and got 44 applications. Three of them were from men, all qualified. We’ve always had a female in that position and would like to keep it that way. We will winnow the applicant pool to five interviews. Must we include one of the men to avoid charges of sex discrimination?  – D.G., Pennsylvania
