A woman undergoing IVF will need to have her eggs extracted, which needs to be done through a puncture needle under ultrasound monitoring. Egg retrieval is one of the most important steps in IVF, which requires the patient to lie down, disinfect the vulva and vagina, and the doctor will use a puncture needle to pass through the vagina, puncture the posterior fornix of the vagina, and then reach the ovaries to retrieve follicular fluid from the ovaries, and then search for eggs from the follicular fluid outside of the body in order to prepare the eggs for IVF. After egg retrieval, embryo transfer and other operations are also required, so women need to actively cooperate with the doctor and seek timely medical treatment so as not to affect the normal IVF process. If there is any discomfort, it is recommended to go to the hospital in time for examination and follow the doctor’s instructions to deal with the treatment.
