What are the ways of IVF pregnancy?
IVF is a kind of assisted human fertility technology, which enables couples who cannot conceive naturally to achieve their reproductive aspirations through in vitro fertilization and embryo culture. There are many ways to conceive test tube babies. Here are some common methods from different aspects.
1. In vitro fertilization embryo transfer
In vitro fertilization embryo transfer is one of the most common IVF methods. This process usually includes the following steps:
The first step is that the woman receives ovulation guidance treatment to make her ovary produce multiple mature follicles.
The second step is to fertilize the collected eggs in vitro with the sperm provided by the man.
The third step is to cultivate the fertilized eggs into embryos.
The fourth step is to select the healthiest embryo for intrauterine transplantation.
The fifth step is to observe the implantation and development of the embryo.
This method is applicable to infertility patients in many different situations, such as fallopian tube obstruction, male sperm abnormality, etc. In vitro fertilization embryo transfer (IVF-ET) has been widely used in the world, and has a high success rate.
2. In vitro fertilization - intracytoplasmic sperm injection
In vitro fertilization intracytoplasmic sperm injection is another common method of IVF. This method is suitable for some patients with abnormal male sperm or poor female egg quality.
This process usually includes the following steps:
The first step is that the woman receives ovulation guidance treatment to make her ovary produce multiple mature follicles.
The second step is to inseminate the collected eggs in vitro with the sperm provided by the man.
The third step is to select a healthy single sperm from the fertilized eggs.
The fourth step is to inject monosperm into the cytoplasm of the egg through microinjection technology.
The fifth step is to observe the implantation and development of the embryo.
This method effectively avoids some infertility problems caused by sperm abnormalities, and improves the success rate of embryo implantation.
3. Third party egg/embryo donation
Third party egg/embryo donation is another form of IVF. When both couples have egg or sperm quality problems and cannot obtain their own healthy eggs or embryos, they can choose to accept eggs or embryos donated by a third party.
This method usually includes the following steps:
The first step is to find suitable donors.
The second step is that the donor receives ovulation guidance treatment to produce multiple mature and healthy eggs.
The third step is to fertilize the donor's egg with the sperm provided by her husband.
The fourth step is to observe the implantation and development of the embryo.
This method gives couples who are unable to conceive naturally the opportunity to continue childbirth, and has achieved a considerable success rate.
4. Frozen technology after embryo transfer
Cryopreservation after embryo transfer is also one of the common ways of IVF pregnancy. The process flow is as follows:
The first step is that the woman receives ovulation guidance treatment to make her ovary produce multiple mature follicles.
The second step is to transplant the fertilized egg into the uterus.
The third step is to freeze the surplus healthy embryos.
Step 4: If the first transfer is not successful, you can choose to unfreeze some embryos for retransplantation.
This method can improve the success rate of IVF pregnancy, and allow couples to reuse frozen embryos when needed, saving time and human resources.
summary
There are various ways of IVF pregnancy, and everyone's situation is different. It is the most important to choose a suitable method. In vitro fertilization embryo transfer, in vitro fertilization intracytoplasmic sperm injection, third-party egg/embryo donation and cryopreservation after embryo transfer are common breeding methods. The development of these technologies provides hope for couples who are unable to conceive naturally, and has achieved a considerable success rate, which has brought good news for them to realize their fertility aspirations.
