In vitro fertilization (IVF) is a medical method that combines eggs with sperm, cultivates embryos, and then implants them into women's uterus to help infertile couples achieve pregnancy and fertility. The long case of IVF involves multiple steps and links, which will be described in detail from the aspects of physical examination, treatment plan, embryo culture and embryo transfer.

Physical examination
Physical examination is the starting point of IVF program, which includes male sperm quality examination and female miscellaneous gynaecological examination. Men need to carry out sperm quality inspection, including semen analysis, sperm vitality, morphology and other indicators to determine whether there is infertility. Women need to carry out miscellaneous gynecological examinations, including ovulation function, endometrial thickness, oviduct patency and other indicators, to understand the female ovulation and the suitability of the uterine environment.
According to the physical examination results, the doctor will develop a personalized treatment plan for the couple.
Treatment plan
The treatment plan of IVF depends on the different conditions of the couple, including ovulation promoting drug treatment, egg retrieval, sperm collection and processing, etc.
First of all, for women, if ovulation function is poor, doctors usually give ovulation promoting drugs to improve ovulation rate. In addition, follicular monitoring is also needed to determine the maturity of eggs and the exact time of egg retrieval.
Secondly, egg retrieval is a key step in IVF. At an appropriate time, doctors use ultrasound guided fine needles to extract women's mature eggs. This process is usually completed in the operating room and requires anesthesia. After taking eggs, the eggs will be sent to the laboratory for sperm treatment and embryo culture.
For men, sperm collection usually uses the method of artificial pregnancy aid to obtain high-quality semen samples by manual means or using specific equipment. Then, laboratory technicians will process the sperm samples, screen out high-quality sperm, and combine them with eggs.
Embryo culture
The successfully fertilized eggs will be cultured in the laboratory. Common embryo culture methods include in vitro fertilization embryo culture embryo blastocyst culture and oocyte culture technology.
In vitro fertilization embryo culture embryo blastocyst culture method refers to the cultivation of high-quality embryos to the stage of blastocyst development. The success rate of embryo implantation will be higher through culture to the stage of blastocyst development.
Oocyte culture technology refers to the use of the embryo development potential of the egg itself to cultivate oocytes into early embryos, and then implant them into the uterus. This method is suitable for some special cases, such as older women or poor sperm quality.
embryo transfer
After the completion of embryo culture, doctors will choose the right time to implant high-quality embryos into the uterus of women. Embryo transfer can be carried out through vagina or abdominal cavity. In general, vaginal transplantation is a common choice, which is simple, safe and does not require surgical incision. Abdominal transplantation is generally used in special circumstances, such as multiple failures of test tube babies or abnormal uterine morphology.
After embryo transfer, the success rate of IVF depends to some extent on factors such as embryonic development, uterine environment and immune status.
summary
The long case of IVF involves many links, including physical examination, treatment plan, embryo culture and embryo transfer. By formulating personalized treatment plans according to the specific conditions of infertile couples, high-quality embryos obtained by in vitro fertilization technology will be implanted into women's uterus to achieve the goal of pregnancy and fertility. However, IVF is not successful every time, and its success rate is related to many factors. When couples carry out IVF plans, they should pay attention to selecting regular and experienced hospitals, and take auxiliary treatment and health care measures according to doctors' suggestions to improve the success rate.
