The gynaecological cycle of the third generation IVF in Beijing
As an assisted reproductive technology, IVF has been widely used in many hospitals in Beijing. In the process of the third generation IVF recovery cycle, detailed arrangements and operations are usually required from many aspects. This article will elaborate on Beijing's third generation IVF's gynaecological cycle from four aspects: drug regulation, egg collection, fertilization and embryo transfer, so as to help people better understand this process.
Drug regulation
Before the convalescence cycle of test tube babies, doctors will develop personalized drug control programs according to the specific conditions of patients. These drugs usually include ovulation promoting drugs and anti estrogen drugs. Ovulation promoting drugs can stimulate ovarian development and increase the number of ovulatory follicles. Anti estrogen drugs can inhibit the production of endogenous estrogen and avoid spontaneous ovulation. On the one hand, this can improve the success rate of egg collection, on the other hand, it can also control the ovarian cycle and coordinate it with the subsequent embryo transfer steps.
In the process of drug regulation, doctors will conduct regular ultrasonic examination and blood hormone determination according to the reaction of patients. This can help doctors understand the development of the ovary and make adjustments according to specific conditions. Generally speaking, the drug regulation cycle is 10-14 days. During this period, patients need to take drugs on time and observe under the guidance of doctors.
Egg collection
Egg collection is one of the key steps of IVF, and also the most stimulating link in the whole cycle of rehab. At a predetermined point in time, the patient will be scheduled for an ovarian puncture to empty the eggs from the ovary. Before the operation, the patient needs to be anesthetized to ensure the safety of the operation process.
The technique of transvaginal puncture under the guidance of B-ultrasound is generally used for egg collection. Doctors use a slender needle to puncture the ovary, extract the eggs and place them in the culture medium for preservation. The whole operation process is usually short, about 20-30 minutes.
After the eggs are collected, the doctor will evaluate the quality of the collected eggs and communicate with the patient to determine the way of subsequent embryo culture and fertilization. In general, doctors will recommend in vitro fertilization of the collected eggs and sperm.
Fertilization treatment
In Beijing's IVF center, in vitro fertilization (IVF) or single sperm injection (ICSI) is usually used for fertilization. In the process of in vitro fertilization, the doctor will put the sperm and egg together in the culture dish to fertilize them naturally. In the process of single sperm injection, doctors hold a microscope to combine sperm and eggs.
The fertilization process generally takes 24-48 hours. During this period, doctors will observe the fertilized eggs and evaluate the embryo quality according to the fertilization. Generally, high-quality embryos will be preferentially selected for transplantation, while the remaining embryos can be frozen for future use.
embryo transfer
The IVF center in Beijing usually arranges embryo transfer three to five days after the fertilized eggs are cultured. This is a simple and painless operation, usually without anesthesia.
In the process of embryo transfer, the doctor will insert a catheter through the vagina and put the selected embryo into the uterus. The whole procedure only takes a few minutes, and then the patient can resume normal activities in a short time.
After transplantation, patients need to take prescribed rest and precautions according to the doctor's recommendations. Doctors may recommend that patients continue to take drugs to provide an appropriate uterine environment and increase the success rate of embryo implantation. After about two weeks, the patient usually needs blood pregnancy test to confirm whether the pregnancy is successful.
Summary
In the Beijing IVF Center, the cycle of the third generation IVF is usually composed of drug regulation, egg collection, fertilization and embryo transfer. Drug regulation can help regulate the ovarian cycle and promote ovarian development, laying the foundation for egg collection and fertilization. Egg collection is one of the most critical steps in the cycle of gynaecology. In the fertilization stage, sperm and egg are combined through in vitro fertilization or single sperm injection technology. Embryo transfer is the last step. Put the selected embryos into the uterus to improve the success rate of pregnancy. Through accurate planning and operation, the whole process provides patients with an effective assisted reproductive technology to help them realize their reproductive dreams.
