Treatment cycle of IVF
IVF is an assisted reproductive technology, which is widely used in many infertile couples. The treatment cycle includes multiple steps, from preliminary examination to final embryo transfer, which requires a certain amount of time and patience.
The first step in the treatment cycle is a preliminary examination. Infertile couples will receive physical examination and relevant laboratory tests to understand the potential causes of infertility. These examinations usually include blood and endocrine examination, ultrasonic examination, hysteroscopy, etc. Through these tests, doctors can judge whether it is suitable for IVF treatment.
Once it is confirmed that IVF treatment is suitable, the next step is to take ovulation promoting drugs. The role of these drugs is to promote follicular development and increase the number of eggs. During drug treatment, doctors will regularly conduct ultrasonic examination and blood testing to determine the size and number of follicles. Generally speaking, the duration of drug treatment is 10 to 14 days.
When the follicle develops to the appropriate size, the next step is egg collection. At this time, women will experience a simple surgical process called ovarian stimulation. Doctors use ultrasound guided fine needles to remove mature eggs from the ovary. This process is carried out under anesthesia and usually takes only a few minutes.
The collected eggs will be fertilized in vitro with male sperm in the laboratory. This is a key step that requires professional technical support. The successfully fertilized egg will be further cultured in a culture dish, usually for several days, until it develops into an embryo.
When the embryo develops to the appropriate stage, the last step is embryo transfer. The embryo will enter the mother's uterus through an appropriate way, and then continue to develop and embed in the uterine wall. This process is usually painless and does not require anesthesia. After a few days, the doctor will conduct a blood test to determine whether the embedding is successful.
Predictors of IVF success
The success of IVF treatment is one of the most important issues for couples. Although each case has certain differences, there are some common predictors that can help couples understand the possibility of success in treatment.
Age is an important predictor. The age of women has a great influence on the success rate of IVF treatment. Young women usually have better egg quality and quantity, thus improving the chance of pregnancy. In contrast, women over 35 have a lower success rate.
Another important predictor is the quality of eggs. The quality of eggs is directly related to the health of their chromosomes. Chromosome abnormalities may lead to abnormal embryonic development and may not be embedded in the uterine wall. Therefore, egg quality is an important indicator to predict the success of IVF.
Couples with specific diseases or other infertility factors usually have low success rates. For example, couples with endometriosis, tubal obstruction, or male semen quality problems may face greater difficulties. These factors also need to be taken into account to predict the success rate of IVF treatment.
The past IVF treatment history can also be used as an indicator. If the couple has tried many times but failed, the success rate may be reduced. Treatment history records can help doctors understand the special situation of couples and develop more appropriate treatment plans.
summary
The cycle of IVF treatment includes preliminary examination, administration of ovulation promoting drugs, egg collection, in vitro fertilization and embryo transfer. Each step requires the professional skills of doctors and the patience of couples. Age, egg quality, existing infertility factors and treatment history are all important indicators to predict the success of IVF treatment. Couples can consult with doctors in detail to understand their own situation and develop appropriate treatment plans.
