IVF cycle progression steps
IVF refers to the process of cultivating fertilized eggs in the laboratory through assisted reproduction technology, and then transferring the embryos to the mother's uterus to develop into babies. This technology provides many infertile couples with the opportunity to realize their reproductive dreams. The steps of IVF feeding cycle will be described in detail below.
Preparation before operation
The first step in the IVF cycle is a comprehensive examination and evaluation of the patient. The doctor will understand the physiological condition of the patient and determine whether it is suitable for IVF through physical examination, blood examination, ultrasonic examination, etc. of both parties. In addition, it is also necessary to understand the genetic condition of patients in order to prevent the occurrence of genetic diseases.
In the preparation before surgery, patients also need to receive training on assisted reproductive technology. This includes methods of injecting drugs, self-monitoring of ovulation and understanding of the embryo transfer process. The patient also needs to sign the corresponding document, agree to carry out IVF, and plan the schedule of IVF cycle according to the doctor's guidance.
In addition, before surgery, patients also need to use ovulation promoting drugs to produce multiple mature eggs in a cycle. This can improve the chance of successful fertilization and increase the scope of embryo selection.
Egg retrieval process
Fetching eggs is one of the key steps in IVF cycle. Within 36 hours after ovulation is triggered, the patient will undergo an ovum retrieval operation. The operation is usually carried out in a formal reproductive hospital by an experienced team of doctors and nurses.
Oval retrieval is generally conducted by transvaginal ultrasound. During the operation, the doctor punctures the follicle in the ovary and aspirates the egg through the vaginal guide needle and ultrasonic monitoring. This process usually takes 15 minutes to half an hour, and patients usually complete the operation under anesthesia or sedation.
After the egg retrieval operation, the patient needs to rest for a period of time to recover. The doctor will observe the patient's physical condition to ensure that no complications occur. The obtained eggs will be fertilized in vitro to produce embryos.
Embryo culture and selection
The obtained eggs and sperm are placed in a culture dish, and after a certain period of culture, the eggs are fertilized into embryos. Doctors will observe the development of the embryo and assess its quality and development potential.
According to the development of the embryo, the doctor will discuss with the patient whether to carry out single embryo transfer. Single embryo transfer can reduce the risk of multiple pregnancy and improve the success rate of IVF. If the patient has surplus embryos, cryopreservation can be selected.
embryo transfer
Embryo transfer is the last step in the IVF cycle. The doctor will transfer the embryo to the patient's uterus through a catheter, and then let it naturally develop into a baby. The whole process usually does not require anesthesia, and the patient only needs to lie on the operating table, and the doctor completes the embryo transfer under the guidance of transvaginal ultrasound.
After embryo transfer, the patient needs to lie down for a period of time to make the embryo attach to the uterine wall better. Next, the patient needs to wait for 12-14 days for a pregnancy test, that is, blood or urine HCG test to confirm pregnancy.
To sum up, the IVF cycle mainly includes the preparation before surgery, egg retrieval process, embryo culture and selection, and embryo transfer. This series of steps requires the joint efforts of doctors and patients to achieve the goal of IVF birth through scientific methods and technologies.
