Yes. Title IX prohibits harassment of students based on sex, including harassment because of pregnancy or related conditions. Harassing conduct can take many forms, including verbal acts and name-calling, graphic and written statements, and other conduct that may be humiliating or physically threatening or harmful.
Actions that could constitute prohibited harassment include making sexual comments or jokes about a student’s pregnancy, calling a pregnant student sexually charged names, spreading rumors about her sexual activity, and making sexual propositions or gestures.
