What steps are required for the IVF cycle:
IVF technology is an important achievement of modern reproductive medicine, which can help couples who cannot conceive naturally due to reproductive system problems to realize their reproductive dreams. The cycle of IVF is a complex process, which requires cooperation and cooperation of multiple steps. The cycle of IVF will be introduced in detail from four aspects: ovarian stimulation, egg collection, in vitro fertilization and embryo transfer.
1. Ovarian stimulation
Before the IVF cycle, ovarian stimulation is required to promote the development of multiple mature follicles in the ovary. This is usually achieved by giving hormones, and the type and dosage of hormones depend on individual conditions. Hormones are usually given by injection, which requires regular monitoring of ovarian response and follicular growth. The monitoring results will guide the subsequent steps. For each case, the adjustment of dose and cycle is essential
The ovarian stimulation cycle usually lasts 10-14 days until the follicle reaches the predetermined size and number. At this time, the eggs reached the stage suitable for collection.
2. Egg collection
Egg collection is one of the key steps in the IVF process, which needs to be carried out at an appropriate time, usually after the follicle reaches a certain level of maturity. The surgical approach is usually vaginal puncture, using ultrasound guided fine needle to extract eggs. Normally, this process is carried out under general anesthesia to ensure the comfort and safety of patients.
During the collection process, doctors will use ultrasound technology to guide the needle to reach the ovary and accurately extract eggs. These eggs will then be fertilized in vitro by combining with sperm in the laboratory.
3. In vitro fertilization
In vitro fertilization refers to the combination of eggs and sperm in the laboratory, so that fertilization occurs in vitro. This requires the collection of high-quality sperm samples. During in vitro fertilization, conventional IVF or ICSI can be selected. Conventional IVF is to add multiple sperm into the culture dish of the egg, and then observe the fertilization. ICSI is to select a single sperm to be injected into the egg, which is achieved through micromanipulation. Both of these methods can effectively achieve fertilization, and doctors will choose the appropriate method according to the specific situation.
After fertilization, the embryos in the culture dish will continue to be cultured in the laboratory for several days to ensure the healthy development of the embryos. Normally, doctors will choose the healthiest one or more embryos for transplantation.
4. Embryo transfer
Embryo transfer is the last important step in the IVF cycle. Before transplantation, the doctor will prepare the endometrium of the patient, and usually needs to give hormones to enhance the thickness and improve the quality of the endometrium.
The process of embryo transfer is generally simple and fast. The guide wire guides the embryo into the uterus and places it in the most suitable position for embryo implantation. This process does not require anesthesia, and patients can complete it under the guidance of doctors.
After embryo transfer, patients need to wait several days for blood tests to confirm whether the pregnancy is successful. If the pregnancy is successful, the growth of the embryo and the health of the patient need to be closely monitored in the next few weeks. If the pregnancy is not successful, you can choose to try IVF again, or choose another birth method according to the doctor's advice.
summary
The cycle of IVF includes ovarian stimulation, egg collection, in vitro fertilization and embryo transfer. This process requires the precise operation of doctors and patient's patience. Through these steps, many couples have successfully realized their reproductive dreams and have healthy and lovely babies.
Today, we briefly introduced the cycle process of IVF, hoping to help you.
