Is it best to ask see a male doctor for testicle exam or should i just book an appointment with my regular female doctor?

While it's a personal choice, it's generally fine to see a regular female doctor for a testicle exam. Doctors, regardless of gender, are trained in performing testicular exams as part of routine check-ups. They follow set guidelines and have experience in maintaining patient privacy and comfort during the examination. That being said, if you have any personal preferences or feel more comfortable with a specific gender of doctor, you have every right to request a male doctor. Whatever makes you feel most at ease is the most important factor in maintaining your health and well-being.
