What is the process of IVF birth?

In vitro fertilization (IVF) is the technology that combines eggs and sperm in a test tube, and then transfers the fertilized eggs to the mother's uterus. This technology gives some infertile couples the opportunity to have children. The following will elaborate the process of IVF production from four aspects: egg collection, in vitro fertilization, embryo culture and transplantation.

Egg collection

The first step of IVF is to collect eggs. A few days before the beginning of the female ovulation period, the doctor will monitor the ovulation of the ovary to determine the best collection time. The collection of eggs usually requires ultrasound guided ovarian puncture to remove the eggs from the follicles. This process is usually carried out in the operating room, and patients will generally receive local anesthesia or intravenous anesthesia.

The collected eggs will be sent to the laboratory for in vitro fertilization.

In vitro fertilization

In vitro fertilization refers to the combination of collected eggs and sperm in a culture dish. Normally, doctors will choose the best sperm from the semen samples donated by men. Then, eggs and sperm will be placed in the culture dish for a period of time to promote fertilization.

Once fertilization occurs, the embryo begins to form. After 24-72 hours, the doctor will evaluate the quality of the embryo and select the best embryo for transplantation or cryopreservation.

Embryo culture

In the process of in vitro fertilization, the cultured embryos need to be further developed under laboratory conditions. Normally, the embryo will continue to be cultivated in the culture dish for 2-6 days until the time for transplantation is reached. During the process of embryo culture, laboratory personnel will regularly observe the development of embryos to ensure their normal development.

If multiple embryos are well developed, doctors and patients can decide to transfer multiple embryos or choose to freeze them for future use.

embryo transfer

Embryo transfer is the last step in the IVF process. Normally, on the third to fifth days of embryo culture, doctors will transfer the selected embryos into the mother's womb. This process is usually painless and does not require anesthesia.

After transplantation, women usually need rest and recovery. Two weeks after transplantation, the doctor will conduct a blood test to confirm whether the embryo is successfully embedded and whether it is pregnant.

In general, the production process of IVF includes four main steps: egg collection, in vitro fertilization, embryo culture and embryo transfer. This technology has provided an opportunity for infertile couples to achieve their reproductive aspirations, and has been successfully applied in many real hospitals.
