In Vitro Fertilization (IVF) Operation Procedure

IVF is a kind of in vitro fertilization technology, which is used to help couples who cannot conceive naturally achieve their reproductive aspirations. The specific operation process of IVF will be described in detail below.

Preliminary assessment and preparation

Before IVF, doctors will conduct a comprehensive assessment of the couple's reproductive health. This includes the examination of women's uterus, ovarian function and ovulation, and the examination of men's semen quality. Doctors will also learn about the couple's lifestyle, family history and other information.

If the evaluation results show that IVF is a suitable choice, the doctor will explain the details of the whole process to the couple and prepare for the next step.

Ovulation regulation

In the IVF procedure, doctors usually use drugs to regulate women's ovulation cycle. This can help increase the number of mature eggs produced by the ovaries and determine the best time to conceive.

Drug treatment includes the use of synthetic hormone drugs to stimulate the ovary to produce multiple follicles to increase the chance of fertilization. Doctors will conduct regular ultrasound and blood tests to monitor the growth of follicles and changes in hormone levels.

Once the follicle is mature, the doctor will arrange the next operation.

Egg collection and sperm preparation

Egg collection is usually carried out at a predetermined time. Doctors use ultrasound guided slender needles to puncture the ovary and extract the fluid and eggs from the follicle. This process is usually completed under general anesthesia to ensure the patient's comfort.

At the same time, doctors will collect male semen samples. Sperm samples will be processed and prepared in the laboratory to improve the success rate of pregnancy.

Fertilization and embryo transfer

In the laboratory, doctors fertilize eggs and sperm to form embryos. Generally, the fertilization rate is 60-70%. After fertilization, the embryos will continue to be cultured in the culture dish for 1-6 days until they reach the optimal transfer state.

The doctor will decide how many embryos to transfer back to the mother according to the specific situation of the couple. This process is usually painless and completed quickly. Once completed, couples need to rest for a period of time to allow the embryo to have the opportunity to implant and develop.

About two weeks later, the patient will have a blood test to determine whether the pregnancy was successful. If the test result is positive, the IVF operation is successful.

Summary

IVF is a complex technology that requires close cooperation between doctors and patients. Through preliminary evaluation and preparation, ovulation regulation, egg collection and sperm preparation, as well as fertilization and embryo transfer, IVF operation can successfully achieve pregnancy.

However, the IVF procedure does not guarantee a 100% success rate, and each couple's situation is different. Therefore, before considering IVF, couples should fully communicate with doctors to understand all possibilities and risks.
