How big does the follicle need to be to be able to retrieve the eggs? Authoritative experts will answer you

Some women cannot get pregnant through normal means, so they have to do in vitro fertilization, which requires the retrieval of eggs from the woman's body. Before retrieval, the doctor will perform a detailed examination of the woman's follicles. Only when the follicles reach a certain size and mature can the eggs be retrieved.

1. How big does the IVF follicle need to be before the egg can be retrieved? A reproductive expert from the Air Force General Hospital said that the size of the follicle must be between 18 and 25 mm to be considered mature, and only then can egg retrieval be arranged. Ovarian function, the patient's mood, and the ovulation induction plan will all affect the development of follicles. Patients with poor follicle development should not be too anxious. The doctor will adjust the ovulation induction plan according to the patient's specific situation and try to help the patient obtain the appropriate number of eggs.

2. Throughout a woman's menstrual cycle, there is only one chance of ovulation in the middle of the menstrual period. Generally, one mature egg is released from the left or right ovary. In rare cases, one mature egg is released from each ovary. In order to break the limitations of embryo transfer, in vitro fertilization generally adopts an ovulation induction program so that multiple eggs can be obtained for transplantation.

3. During the ovulation induction period, the doctor will monitor the patient's follicle development through B-ultrasound testing. The size of the follicles directly affects the progress of the entire operation, and patients hope that more follicles can develop and mature. So, how big does the IVF follicle have to be before egg retrieval can be performed?

4. The in vitro fertilization expert of the Air Force General Hospital pointed out that after using ovulation-inducing drugs, the growth and development of the follicles of each patient are different, so the time of egg retrieval will also be different. Some patients have better ovarian function and can arrange egg retrieval a few days after the ovulation injection; some patients may adjust the ovulation-inducing plan because the ovulation-inducing effect is not good, which may lead to a delay in egg retrieval.
