Infertility requires first identifying the cause of infertility, whether it is related to male factors or female factors. The likelihood of diet affecting infertility is not very high, however, if there is excessive obesity or extreme thinness, appropriate changes need to be made. Relevant examinations should be conducted, such as tests for blood sugar, insulin levels, etc. Patients with infertility should, like everyone else, avoid overly selective eating habits, pay attention to their weight, and maintain a balanced diet to ensure adequate nutrition intake, and avoid eating junk food.
