According to clinical experience, the chance of getting pregnant for the second time is about 40%~50%, but it varies from person to person, taking into account the patency of the fallopian tubes, the endometrial environment and other factors. Ovulation induction refers to the use of drugs to induce follicular development and discharge to increase the chances of pregnancy. Usually, the chances of pregnancy in the second ovulation induction are about the same as in the first pregnancy, about 40%~50%. If the patient’s tubal patency, endometrial environment, embryo quality, and hormone levels are good, the chances of pregnancy will increase. It is recommended that after ovulation induction, women should maintain a happy mood and eat more food rich in protein and vitamins, which can help increase the chances of pregnancy to a certain extent. If a woman experiences persistent abdominal pain after ovulation induction, it is recommended that she seek medical attention in a timely manner and under the guidance of her doctor, complete the relevant examinations to identify the cause of the problem and treat it.
