Detailed steps and success rate of second-generation IVF

In Vitro Fertilization (IVF) is an assisted reproductive technology, which can help couples who cannot conceive in a natural way to achieve their fertility aspirations. The steps and success rate of second-generation IVF will be described in detail below.

Stage I - Ovulation and ovarian stimulation

The first stage is to stimulate ovarian development and ovulation through the use of ovulation guidance drugs. Usually, women will start injecting drugs on the second day of the menstrual period, and inject them every day until the follicle develops to a large enough size. During this period, the doctor will regularly check the size of female follicles and hormone levels to determine the best operation time.

Once the follicle size and hormone level reach the appropriate level, the doctor will arrange the next step: egg retrieval.

Stage II - Egg taking and sperm collection

The second stage is to guide puncture and egg taking to the ovary. In this process, the doctor will use anesthetic, and then conduct guided puncture through the vagina to extract mature eggs from the female ovary. At the same time, doctors will collect sperm from men.

Doctors will place eggs and sperm in a culture dish for in vitro fertilization. After that, doctors will monitor the development of the fertilized eggs to determine the best time for embryo transfer.

Stage 3 - Embryo transfer

The third stage is to transfer the well developed embryos into the female uterus. This process usually takes place three to five days after fertilization. Doctors will use a catheter to transfer the embryo into a woman's uterus, and then observe whether implantation occurs.

Stage IV - Pre bed and detection

The fourth stage is the observation and verification after embryo transfer. The doctor will recommend a pregnancy test for women, and a blood test will be carried out about 10 days later to determine whether they are pregnant. If the result is positive, women will continue to receive more pregnancy testing and monitoring to ensure the development of embryos.

In terms of success rate, the success rate of second-generation IVF is affected by many factors, including female age, reproductive history, ovarian function and hormone level, and male sperm quality. According to different hospitals and technical levels, the success rate is between 30% and 60%. With the continuous progress of medical technology, the success rate of second-generation IVF continues to increase.

summary

The second generation of IVF is a complex assisted reproductive technology, which achieves the goal of successful pregnancy through multiple stages such as ovulation guidance and ovarian stimulation, egg retrieval and sperm collection, embryo transfer, and pre bed and detection. However, the success rate is affected by many factors, and each couple's situation is unique. Therefore, it is recommended that couples consult professional doctors before choosing the second generation IVF, understand their own conditions and opportunities, and make the right decision.
