The main component of ovulation injections is chorionic gonadotropin, which is mainly used for artificial insemination. However, some women do not ovulate because their follicles are underdeveloped or mature, so ovulation injections can be used to induce follicles to expel. After ovulation injection, the follicles are usually expelled within 36 hours, but the time of ovulation varies from person to person, as some may be expelled within 36 hours after the injection, while others may need a second injection of the drug to be expelled. After the ovulation injection, you need to go to the hospital for ultrasound monitoring on the second day to see if the follicles are discharged successfully, you can clearly see if the follicles are still there under the ultrasound, if they are still there, it means they are not discharged normally, if they have disappeared, it means they have been discharged. You can also test at home with ovulation test paper. If two red lines appear as red as each other, it means ovulation has occurred. After the ovulation injection, you can have intercourse on the first night. If the eggs are not normally ovulated on the second day, you can also have intercourse continuously, which can increase the chance of conception. You can also do some exercises to help the follicles to expel, such as jumping rope, doing yoga or dancing gently. After the ovulation injection, you should also pay more attention to rest and follow the doctor’s instructions strictly to have intercourse to increase the probability of pregnancy.
