1. Definition of IVF
In vitro fertilization embryo transfer (IVF-ET), also known as in vitro fertilization embryo transfer (IVF-ET), is a kind of assisted reproductive technology, which is used to help couples who are unable to conceive naturally due to various physiological reasons realize their reproductive dreams. IVF technology has been widely used in Hongfang Hospital since 1987.
The success cycle of IVF is affected by many factors, including couple's age, reproductive organs, reproductive hormone levels, etc. Generally, the success cycle needs to go through the following four stages.
2. Phase I: Preparation
A successful IVF cycle requires a series of preparations. First, the doctor will conduct a comprehensive physical examination of the couple to assess the ovarian function of the woman and the sperm quality of the man. At the same time, the woman also needs to test the tubal patency to ensure that the embryo can successfully enter the uterus.
After the physical examination result is confirmed, the doctor will give appropriate treatment, such as adjusting the reproductive hormone level of the woman, assisting ovulation or improving the quality of endometrium. In addition, couples also need to receive psychological counseling to be ready to face the pressure and emotional fluctuations in the process of IVF.
3. Stage II: Egg collection and sperm collection
After the preparation phase is completed, the egg collection and sperm collection phase will begin. The woman first received ovulation guidance treatment to promote ovarian development and produce multiple follicles. After confirming the maturity of follicles through ultrasonic monitoring and blood hormone detection, doctors will collect eggs in the operating room. This is a painless small operation, which is carried out by puncture close to the uterus and is usually completed under anesthesia.
At the same time, the man provides semen samples, which are generally collected from the semen after masturbation or sexual intercourse. Then, through centrifugation and other steps, high-quality sperm can be extracted from it.
4. Stage 3: Fertilization and embryo culture
After egg collection and sperm collection, laboratory technicians will combine eggs and sperm for in vitro fertilization. If the quality and quantity of sperm are good, the fertilization rate will be high. After successful fertilization, the embryo will continue to be cultured in the culture dish. This process usually takes three to five days, after which the doctor decides the best time for embryo transfer.
During the process of embryo culture, doctors may recommend embryonic genetic testing to screen for chromosomal abnormalities or other genetic diseases. This helps to select healthy embryos and improve the probability of success of IVF.
5. Stage 4: embryo transfer and implantation
At the stage of embryo culture, doctors will select the most promising and high-quality embryos for transplantation. Embryo transfer is a simple and painless process, usually without anesthesia. The doctor will use a thin tube to place the embryo in the endometrium to help it successfully implant.
After embryo transfer, patients need to relax and continue to take hormone drugs such as estrogen and progesterone to promote embryo implantation and growth. About two weeks later, the patient will have a blood test to determine if she is pregnant.
In general, in Red House Hospital, the success cycle of IVF usually takes 4 to 6 weeks. However, different couples may have different situations, and not every cycle can achieve success. Therefore, before IVF, couples are advised to consult with doctors in detail to understand their own situation and the possibility of success.
Summary
The success cycle of IVF in Red House Hospital usually needs to go through the preparation stage, egg collection and sperm collection stage, fertilization and embryo culture stage, as well as embryo transfer and implantation stage. The whole process usually takes 4-6 weeks. Through scientific assisted reproductive technology, IVF helps couples who cannot conceive naturally realize their reproductive dreams.
