To increase the likelihood of ovulation and have more twins, you should first eat a balanced diet. In addition, you can use ovulation medication under the guidance of your doctor. Under normal circumstances, a woman’s ovaries only produce one egg per month, and only in a few abnormal cases, two eggs appear at the same time. Therefore, it is recommended to have a proper diet and to consume more lean meat, fish, eggs and beans, especially alkaline foods, from the third month of pregnancy. At the same time, you should take more micronutrients and start taking folic acid 3 months before conception. However, diet alone cannot change ovulation and increase the chances of having twins. During the preparation period, oral ovulation-promoting drugs can be used to increase the number of follicles ovulated for the purpose of having twins. However, the artificial use of ovulation-promoting drugs, which induce the ovaries to ovulate more, has the risk of causing premature ovarian failure. Usually, ovulation promotion is not clinically supported to achieve the goal of having twins. It is recommended that women who are preparing for pregnancy should develop good lifestyle habits, avoid staying up late, exercise more and improve their physical fitness.
