What are the steps of Sanya IVF?
IVF technology is a kind of modern reproductive medicine technology, which aims to help couples who are difficult or impossible to conceive naturally realize their reproductive dreams. As one of the famous cities in China, Sanya also provides IVF services. The steps involved in Sanya IVF will be introduced in detail below.
1. Preparation before assisted reproductive technology
Before starting IVF treatment, couples need to undergo a series of physical examinations. The purpose of these tests is to evaluate the reproductive capacity of couples to determine whether it is suitable for IVF. Examination items usually include semen analysis, ovarian function evaluation, endometrial examination, etc. Doctors will also ask the couple's genetic and family history to assess genetic risk.
In the preparation stage, couples also need to accept some assisted reproductive technologies, such as ovulation guidance and ovulation induction. The purpose of these techniques is to increase the ovulation rate and endometrial preparation of patients, and ensure that eggs and sperm can be combined at the right time and environment.
2. Egg collection and sperm collection
Egg collection is an important part of IVF process. Before egg collection, the woman needs ovulation induction treatment. During treatment, doctors will monitor the development of follicles through ultrasound and blood tests. Once the follicle reaches the mature state, the doctor will use ultrasound guided fine needle puncture technology to remove the egg.
Equally important is the acquisition of sperm. Usually, the man needs to provide fresh semen samples. If the man is unable to provide semen or the semen quality is low, doctors can also obtain sperm through semen extraction (TESA) or testicular biopsy and other technologies.
3. In vitro fertilization and embryo culture
After obtaining eggs and sperm, these biomaterials will be fertilized in vitro in the laboratory. This process usually uses in vitro fertilization or oocyte single sperm injection (ICSI) technology. In vitro fertilization is to put multiple sperm and eggs into a culture dish and let them self fertilize. ICSI selects a healthy sperm and injects it into the egg to ensure successful fertilization.
After successful fertilization, the embryo will be cultured in a petri dish. In the process of culture, doctors will simulate the uterine environment and provide the necessary nutrients to promote the development of embryos. The embryo culture usually lasts for 3-5 days. The doctor will carefully observe the development of the embryo and select the best embryo for transplantation.
4. Embryo transfer and pregnancy observation
Embryo transfer is the last step in IVF treatment. The cultured embryos will be transferred to the woman's uterus, usually through the vagina. After embryo transfer, patients need to rest for a period of time to improve the success rate of transfer.
After a few days, the patient will have a pregnancy observation. Doctors can determine whether a pregnancy is successful by detecting progesterone levels in the blood or by performing an ultrasound examination. If the pregnancy is confirmed, the patient will continue to be monitored and nursed during pregnancy.
To sum up, the steps of Sanya IVF include preparation before assisted reproductive technology, egg collection and sperm acquisition, in vitro fertilization and embryo culture, as well as embryo transfer and pregnancy observation. These steps pay close attention to the reproductive capacity of both couples, and carry out fine operations in the laboratory to increase the chances of success of IVF.
