What procedures are needed for IVF
IVF is an assisted reproductive technology that helps couples who cannot conceive naturally realize their dreams of pregnancy and childbirth. The success of IVF is closely related to the professional level, technical equipment and perfect operating procedures of hospitals and doctors. The following will elaborate on several aspects required for the IVF program.
Receptor evaluation and preparation
Before IVF treatment, the doctor will conduct a comprehensive evaluation of the receptor. The purpose of this step is to determine whether the recipient's body and reproductive system are suitable for IVF treatment. Receptor evaluation includes detailed examination of the physical health status, reproductive history, age, and uterine condition of the receptor.
After evaluation and determination of appropriate IVF treatment, the receptor needs to take a series of preparation measures. This includes necessary physical examination, such as blood examination, electrocardiogram, ultrasonic examination, etc., to ensure that the body is in good condition and can safely perform IVF surgery.
In addition, the recipient also needs to receive psychological counseling, understand the process and possible risks of IVF treatment, and be prepared for the treatment results.
Ovarian stimulation and collection
In IVF treatment, the receptor first needs ovarian stimulation to increase the number of ovulation and improve the success rate of pregnancy. Doctors will develop individualized stimulation programs and monitor the development of follicles according to the physical condition of the receptor and relevant indicators.
After ovarian stimulation, the doctor will conduct follicle puncture through vagina or abdominal wall to take out the mature eggs. This operation needs to be carried out under painless or general anesthesia and operated by experienced doctors. The removed eggs will be sent to the laboratory, ready to be fertilized with sperm.
Sperm collection and fertilization
For men in IVF treatment, doctors will conduct sperm collection. Generally, men can collect semen samples by manual stimulation or using special instruments. Then, these sperm samples will be processed in the laboratory to screen the sperm with high fertilization ability.
In the fertilization operation, doctors can choose the conventional IVF method, that is, the sperm and egg are cultured together for fertilization, or they can choose the single sperm injection (ICSI) technology to inject a sperm with fertilization ability into the egg for fertilization. These operations are usually completed by laboratory technicians and require careful operation and precise control.
Embryo culture and transfer
After fertilization, the eggs will be cultured in the laboratory. Doctors will select the most promising embryos for culture and decide the best time for embryo transfer according to the egg quality and embryo development. Embryo transfer is usually carried out in the development stage of 5-6 days.
Embryo transfer is the last step of IVF treatment. The doctor will place the embryo into the recipient's uterus through a catheter. The operation generally does not require anesthesia, but is performed through the vagina, and the operation time is relatively short. After transplantation, the recipient needs to rest and observe to increase the chances of embryo implantation.
Summary
IVF is a complex treatment technology, which requires a series of detailed procedures. From receptor evaluation and preparation, to ovarian stimulation and collection, to sperm collection and fertilization, and finally to embryo culture and transplantation, every step requires careful operation and monitoring by doctors and technicians. Through reasonable program implementation, IVF technology can effectively increase the success rate of pregnancy and realize the desire of couples who cannot conceive naturally.
