What is the process and cycle of IVF

In Vitro Fertilization (IVF) is an assisted reproductive technology, which can achieve pregnancy and pregnancy by fertilizing female eggs and male sperm in vitro, and then transplanting the fertilized eggs back to the female uterus. Next, we will elaborate on the whole process and cycle of IVF from four aspects.

Select hospitals and conduct preliminary evaluation

First, it is critical to choose a formal assisted reproductive technology hospital. In China, such as the Reproductive Medicine Center of Peking Union Medical College Hospital and the Reproductive Medicine Center of Ruijin Hospital affiliated to Shanghai Jiaotong University School of Medicine are well-known and professional IVF hospitals. Patients can choose suitable hospitals according to their own conditions. In the preliminary assessment, the doctor usually conducts detailed inquiries and physical examinations. They will learn about the couple's reproductive history, the patient's menstrual cycle, ovarian conditions, etc., and also carry out necessary screening, such as endometrial thickness testing, sex hormone level testing, to determine that the patient is suitable for IVF.

Ovulation induction and egg collection

In the IVF cycle, ovulation promotion and egg collection are very important steps. Generally, the first step is to promote the development and growth of ovarian polycystic follicles through drugs. The doctor will make a personalized treatment plan according to the patient's condition, and regularly carry out ultrasonic examination and blood testing to monitor the size and number of follicles. When the development of ovarian polycystic follicles reaches a certain stage, doctors will terminate the development and promote ovulation, usually using human chorionic gonadotropin (hCG) injection to induce ovulation. About 36 hours later, the doctor will quickly send the removed eggs to the laboratory for follow-up operations through vaginal oviduct or laparoscopic ovum retrieval.

Fertilization and embryo culture

In the laboratory, doctors conduct in vitro fertilization of the collected eggs and sperm, which is the origin of in vitro fertilization. Sometimes, in order to increase the success rate of fertilization, doctors may use ICSI technology to inject a single sperm into the egg. After 24-48 hours of culture, the formed embryos can be evaluated. According to the quantity and quality of embryos, doctors and patients together decide how many embryos to transfer back to the patient's uterus. The remaining embryos can be frozen for future use.

Transplantation and pregnancy

Embryo transfer is the last step of IVF. Before transplantation, doctors usually confirm the good condition of endometrium through ultrasonic examination. The embryos were then transferred directly into the uterine cavity through a vaginal catheter. After transplantation, patients need a period of rest and recovery. After about 12 days, a blood test can determine whether the pregnancy is successful. If the test tube baby is successful, the patient will continue to have prenatal examination until the final delivery. Through the detailed elaboration of the above four aspects, we can understand the whole process and cycle of IVF. The first is to select a hospital and make a preliminary assessment, then to promote ovulation and collect eggs, then to fertilize and culture embryos, and finally to embryo transfer and pregnancy. The success of IVF depends on many factors, but modern medicine and superb technology provide a new hope and opportunity for couples who are eager to become parents.
