When doing IVF, if a woman can normally ovulate mature eggs, she can have natural egg retrieval without ovulation injections. Ovulation injections are used to promote the growth and ovulation of follicles, and can be used in IVF, usually in anovulatory patients, to induce follicular growth and development, and to promote the ovaries to release normal mature eggs. If the woman herself can ovulate normally, then the eggs can be retrieved directly with the egg retrieval needle through the vaginal fornix, removed and combined with sperm for IVF. Therefore, it is possible to skip the ovulation injection. It is recommended that when a woman undergoes IVF, she should first seek medical advice to complete the relevant examinations, and consult the doctor in time to standardize the treatment after encountering abnormalities.
