The whole process of second-generation IVF treatment
IVF is an assisted reproductive technology that helps couples who cannot conceive naturally realize their reproductive dreams through in vitro fertilization (IVF) and embryo transfer. As an advanced form of IVF technology, second-generation IVF treatment is increasingly popular worldwide. The whole process of second-generation IVF treatment will be introduced in detail below.
Phase I: Diagnosis and evaluation
Before starting the second-generation IVF treatment, couples need to go to professional reproductive hospitals for diagnosis and evaluation. The doctor will first carry out detailed physical examination, including women's prenatal examination, men's semen analysis and genetic testing of both sides. In addition, basic reproductive hormone examination, ovarian reserve assessment and endometrial thickness will also be carried out. Through these examination results, doctors can determine whether couples are suitable for second-generation IVF treatment and choose the appropriate treatment scheme.
According to the diagnosis results, the doctor will communicate with the couple in detail to explain the treatment process, possible risks and success probability. At the same time, couples can also ask doctors questions to learn more about treatment related issues. Finally, the couple decided whether to carry out second-generation IVF treatment and enter the next stage.
Stage II: Hormone therapy and ovarian stimulation
In the second stage of second-generation IVF treatment, women need hormone therapy and ovarian stimulation. Doctors will make personalized treatment plans according to the diagnosis results and the wishes of the couple.
Hormone therapy includes the use of micro hormones for routine regulation to improve the probability of pregnancy. Ovarian stimulation mainly stimulates ovarian development by injecting ovulatory hormone drugs, increases the number of follicles, and improves the success rate of in vitro fertilization. This process usually lasts for 10-12 days. The doctor will regularly check the follicular growth and hormone levels to determine the best time for ovulation.
Stage 3: egg retrieval and sperm treatment
When the follicle reaches the appropriate size, the doctor will use ultrasound guided fine needle puncture technology to remove the mature egg. The operation is usually performed under local anesthesia or general anesthesia, and will not affect women's health.
At the same time, men need to provide fresh semen samples or cryopreservation of semen. The doctor will wash and treat the sperm to obtain the healthiest sperm and improve the fertilization rate.
Stage 4: Embryo culture and transfer
After taking the eggs, the doctor fertilizes the eggs and sperm in an in vitro culture dish to form an embryo. The embryo will further develop in the culture dish for several days, and then select the best embryo for transplantation.
Embryo transfer is the placement of fresh or frozen embryos into a woman's uterus through a catheter. This process is usually carried out under painless or local anesthesia and does not require hospitalization. Doctors will choose the most suitable time and quantity of embryo transfer according to the couple's age, embryo quality, doctor experience and other factors.
After the completion of embryo transfer, the couple needs to follow the doctor's advice for rest and health care, and wait for the results. About two weeks later, blood or urine progesterone test can be carried out to confirm whether pregnancy.
To sum up, the whole process of second-generation IVF treatment includes diagnosis and evaluation, hormone therapy and ovarian stimulation, egg retrieval and sperm treatment, and embryo culture and transplantation. Strict investigation and operation are required at each stage, and full communication and cooperation between doctors and couples are also crucial. After this series of steps, many couples have successfully welcomed their baby.
