Next, We Will Introduce The Process Of Egg Collection in Detail.

The first step is controlled superovulation: because the natural menstrual cycle is different from person to person and the same patient has different cycles, it is not easy to arrange the time of egg collection. Moreover, only one upper follicle develops in the natural cycle, and only one embryo can be formed after fertilization, and the pregnancy rate of transferring one embryo is very low. Therefore, it is necessary to use controlled superovulation to enhance and improve ovarian function, so as to achieve the goal of obtaining multiple healthy eggs without the restriction of natural cycle, providing multiple embryo transfer, and synchronizing luteal development and endometrial function as much as possible. In controlled superovulation, GNRHA is used to modulate FSH and LH in vivo, and then HMG or FSH ovulation drugs are administered to stimulate the growth of ovarian follicles. The dosage of drugs is adjusted according to the patient's reaction to drugs. The number of eggs obtained varies with the patient's age and dose of drugs.

The second step is follicular monitoring: in order to evaluate the effect of ovarian stimulation and determine the time of egg collection, vaginal B-ultrasound should be used to monitor the size of follicles, and the E2 value (estrogen) should be checked with blood sampling to adjust the dosage. When more than two to three follicles are larger than 1.8cm in diameter and the number of follicles above 1.4cm equals E2, human villous gonadotropin (HCG) can be injected to induce follicle maturation. Eggs were collected 34 ~ 36 hours after injection of HCG.

The third step is egg collection: the most commonly used method of egg collection is under local anesthesia, guided by vaginal B-ultrasound, to pass the egg collection needle through the vaginal fornix to the ovary to absorb the egg, and immediately move the egg under the microscope to the petri dish containing embryo culture medium, and culture in 37°C incubator.

As an essential step in the process of IVF, the care after egg retrieval is equally important, which is related to the success or failure of ivf treatment in the future. In general, the doctor will explain the precautions before treatment, so as not to cause irreversible effects due to the patient's negligence.

On the day the eggs are harvested, the sperm bank asks for a contact number. Since carbon dioxide is injected during the operation, there will be pain in two to three days. There is no need to worry too much. If eggs are collected vaginally, there may be a few brown secretions.

After egg collection, the wound should be kept clean. On the third day, the tape can be torn off without removing stitches. At the same time, you can also take a bath.

If the pain is particularly severe, take the medicine as required by your doctor.

On the day after egg collection, lutein and HCG should be injected under the guidance of the doctor. Please contact your attending doctor if you want to inject lutein and HCG in the future. After egg collection, please go to the hospital for emergency treatment immediately if you have decreased blood pressure, rapid heartbeat, pale face, abnormal bleeding, difficulty urinating or high fever.

Under normal circumstances, after egg collection, you can go back to the hospital for embryo implantation every three days. Some can be cultured until the sixth day. After egg collection, the doctor will tell you when to come back for implantation.

After the embryo is implanted, your doctor will tell you how to take medication, give injections and when to come back for blood tests to see if you are pregnant.

In fact, the egg harvesting process is not very long and is carried out under anesthesia. Some people are more sensitive and report some pain; Others report feeling nothing. So, if you want to do ivf, do not panic too much, try to keep a calm state of mind. Pain is certain, but for the lovely baby, the pain also endure.
