Medical procedures for IVF

Test tube baby is a kind of reproduction mode that fertilized eggs are cultured in vitro and then implanted into the mother's body through artificial technology. In order to ensure the success rate and healthy growth of IVF, medical operation is very important. In the following aspects, IVF requires a series of medical procedures, including in vitro fertilization, embryo culture, genetic screening and embryo implantation.

1. In vitro fertilization

IVF is the first step of IVF, mainly including egg collection and sperm extraction. In a safe and clean operating room, the doctor punctures the ovary to the follicle through colposcopy, and uses ultrasound to guide the process. This process usually needs to be carried out during the female ovulation period to ensure the adequacy and best quality of eggs. Once the eggs are collected, sperm extraction will also be carried out at the same time. Sperm can be extracted through natural urination or directly from the testis or vagina. Then, through in vitro fertilization, the egg and sperm are combined to form the fertilized egg in the laboratory.

2. Embryo culture

Embryo culture is an important part of IVF. After the successful formation of the fertilized egg, the embryo will be transferred to the culture dish and placed in a suitable environment for continuous culture. Petri dishes provide sufficient nutrition and a good growth environment to ensure the healthy development of embryos. In the process of embryo culture, doctors will regularly check the development and quality of embryos. The cell division and morphology of each embryo will be evaluated to determine the best embryo selection.

3. Genetic screening

In order to ensure the health of IVF, genetic screening is an essential link, which can include genetic disease screening and gender selection. Genetic disease screening is to detect whether an embryo carries genetic variation of certain genetic diseases. Modern medical technology can detect these lesions early through gene detection, and select healthy embryos for implantation to reduce the risk of disease. In some cases, the family may wish to choose the sex of the embryo. Gender selection through screening of fertilized eggs can meet the family's individual needs and preferences for the child's gender.

4. Embryo implantation

Embryo implantation is the last step of IVF, and also the key to determine whether a successful pregnancy can be achieved. The doctor will transfer the screened healthy embryos to the mother's uterus. The procedure is usually performed through the vagina, without an open abdomen. After embryo implantation, patients need further rest and follow the guidance of doctors to improve the success rate and ensure embryo implantation. Then, the doctor can conduct pregnancy test by means of blood or urine test. IVF requires a series of medical operations, such as in vitro fertilization, embryo culture, genetic screening and embryo implantation, which ensure the smooth development and healthy growth of IVF. With the increasingly perfect medical technology, IVF has become the hope of many infertile families to realize their dreams.
