How long does the treatment course of test tube babies at Shenzhen Peking University take?
IVF is an assisted reproductive technology that can help couples who cannot conceive naturally realize their reproductive dreams. In Shenzhen Peking University Hospital, the IVF treatment needs to go through multiple stages, and the time of each stage is different. The treatment duration of IVF in Shenzhen Peking University will be described in detail from four aspects.
1. Preparation stage
The preparation stage of IVF treatment course is very important, which includes assessing the fertility status of couples, conducting necessary examinations and screening, and developing personalized treatment plans. The time of this stage is usually about 2-3 weeks, and the specific time depends on the situation of the couple.
First, couples need to undergo comprehensive physical examination, including blood examination, reproductive system examination, endocrine examination, etc., to ensure that they are suitable for IVF treatment. Doctors also provide psychological counseling to couples to help them understand and cope with possible physical and psychological stress.
At the end of the preparation phase, the doctor will develop a personalized treatment plan based on the examination results and the couple's personal conditions. The treatment plan will include the use of drugs to regulate women's menstrual cycle, ovulation induction, egg collection, sperm extraction, etc. The whole preparation phase usually takes 2-3 weeks.
2. Egg taking and sperm extraction
Egg retrieval and sperm extraction are the key steps in IVF treatment, and also one of the most tedious stages. This process usually needs to be carried out 12 to 14 days before ovulation.
First, women will use ovulation promoting drugs under the guidance of doctors to increase the number and quality of eggs. Then, when the egg develops to a certain extent, the doctor will use ultrasound guided puncture technology to take out the egg through the vagina. This process usually requires anesthesia, and the specific time depends on the number of eggs and the difficulty of removing them.
At the same time, men also need to provide semen samples on the same day in order to extract sperm. The semen sample will be processed to extract high-quality sperm for subsequent fertilization.
3. In vitro fertilization and embryo culture
After eggs and sperm extraction, the next step is in vitro fertilization and embryo culture. This process usually takes 3-5 days.
First of all, doctors will use in vitro fertilization technology to combine sperm and eggs to produce fertilized eggs.
Then, the doctor will observe the development of the fertilized egg and screen out the well developed embryo. The well developed embryos will continue to be cultured in culture dishes to meet the conditions for transplantation.
4. Embryo transfer and observation
After the completion of embryo culture, the doctor will choose a suitable time for embryo transfer. This process is usually carried out on the third or fifth day after fertilization. The process of embryo transfer is not complicated, but it requires a high degree of technology and experience.
After transplantation, doctors will observe and care the patients to ensure the successful implantation of embryos into the uterus. Later, the patient needs to rest and recover for a period of time, waiting for the results of IVF success.
To sum up, the treatment period of IVF at Shenzhen Peking University mainly includes the preparation stage, egg retrieval and sperm extraction, in vitro fertilization and embryo culture, as well as embryo transfer and observation. The whole process usually takes 4-6 weeks. The time of each stage will vary according to the personal situation of each couple. However, this treatment is a door of hope for couples who cannot conceive naturally, giving them the opportunity to become parents.
