What are the specific steps of the third generation IVF?
The third generation of IVF is an assisted reproductive technology, which can help couples who cannot conceive naturally achieve their reproductive aspirations. It includes egg retrieval, sperm treatment, in vitro fertilization and embryo transfer. The specific steps of the third generation IVF will be introduced in detail below.
Egg retrieval process
Fetching eggs is the first step of three generations of IVF. In some fertility clinics, doctors will use ultrasound guided ovarian puncture technology to carry out this process. First, doctors will inject women with a drug called ovulation promoting drug. The effect of the drug is to stimulate the ovary to produce multiple follicles. Next, doctors will use ultrasound technology to monitor the development of follicles.
Once the follicle is mature, the doctor will use a slender needle to puncture the ovary and extract the egg through the needle. This process generally requires local anesthesia. The process of egg retrieval is often short (about 20-30 minutes). The obtained eggs will be sent to the laboratory for further processing.
Sperm processing
The purpose of sperm treatment is to select high-quality sperm for in vitro fertilization with eggs. Generally, sperm treatment includes the following steps: semen sample collection, sperm separation and sperm motility assessment.
Semen sample collection is usually carried out in a hospital specific environment to ensure sperm quality. After collecting samples, laboratory technicians will separate sperm by special methods to ensure that only the most active sperm is screened. Finally, by evaluating the morphology and vitality of sperm, the best sperm will be selected for in vitro fertilization.
In vitro fertilization
In vitro fertilization (IVF) refers to the combination of the obtained eggs and sperm into an embryo in the laboratory. Laboratory technicians will place eggs and sperm together in a petri dish according to the doctor's instructions. Subsequently, the culture dish will be placed in the incubator to simulate the intrauterine environment and allow the embryo to develop.
Generally, a successful fertilization will show the formation of a fertilized egg within one or two days after fertilization. Doctors will constantly monitor the development of the fertilized eggs and select one or more embryos with the best quality for transplantation.
embryo transfer
Embryo transfer refers to the transfer of successfully developed embryos into the uterus of women to promote the occurrence of pregnancy. The doctor will use a thin tube to gently place the embryo into the uterus at a specific time.
After embryo transfer, women need to continue taking progesterone and other drugs to help embryo implantation and maintain pregnancy. After about two weeks, a pregnancy test was performed to determine whether the pregnancy was successful.
In summary, the specific steps of the third generation IVF are egg retrieval, sperm treatment, in vitro fertilization and embryo transfer. This technology provides a choice for couples who are unable to conceive naturally to achieve their reproductive aspirations.
