Specific steps of IVF

IVF (also known as artificial insemination, in vitro fertilization or assisted reproductive technology) is a medical assisted reproductive technology. The fertilized eggs are artificially cultured in a test tube, and then the embryos are transferred to the mother's uterus for pregnancy. The specific steps of IVF will be described in detail below.

1. Reproductive preparation

Before IVF, both husband and wife need to accept the inspection and evaluation of the reproductive system to ensure that there are no obvious reproductive health problems. Doctors will perform gynecological examination, endocrine assessment and follicle count determination for women, while men need to provide semen samples for semen analysis. If there are reproductive problems, additional treatment may be required.

1.1 Ovulation induction therapy

For women, in order to increase the number of eggs, doctors may use ovulation induction therapy. Through hormone injection or oral medicine, the ovary can produce more mature eggs for fertilization. Doctors will regularly monitor the growth and development of follicles to determine the best time for egg collection.

1.2 Fertilization

When the egg develops to an appropriate stage, the doctor will use a thin tube to directly inject sperm into the egg, or put the sperm and the egg together into a culture dish containing special nutrient solution to let them naturally fertilize. Injection fertilization is a common method, which is suitable for poor quality of male semen.

1.3 Embryo culture

After fertilization, the embryos will be cultured in the cell culture medium so that they can continue to develop and grow. Usually, embryos will be observed in a petri dish for several days to determine which embryos have the best viability.

2. Embryo transfer

Once the embryos have reached the proper stage of development, doctors will transplant them into the female uterus. This is usually a painless process and does not require hospitalization. The doctor will use a thin tube or catheter to gently put the embryo into the uterus, and then the patient needs to rest to increase the probability of embryo implantation.

2.1 Frozen embryo transfer

In some cases, the remaining embryos can be frozen for future use. Frozen embryo transfer is an effective method, which can provide couples with the opportunity to try many times, while reducing the cost and risk of each attempt.

3. Pregnancy monitoring

Once the embryo is successfully transferred, the woman enters into pregnancy. The doctor will conduct regular blood tests and ultrasonic examinations to ensure the normal progress of pregnancy. If there is any problem, the doctor may take appropriate treatment measures to ensure the health of the fetus and mother.

4. Early pregnancy care

After the embryo is successfully implanted, women need to follow specific lifestyle and dietary recommendations to promote the healthy development of the embryo. Your doctor may recommend reducing your daily activity and avoiding strenuous exercise and harmful substances such as nicotine and alcohol. At the same time, women also need to pay attention to dietary nutrition and take in enough vitamins and minerals.

summary

The specific steps of IVF include reproductive preparation, ovulation induction therapy, fertilization, embryo culture, embryo transfer, frozen embryo transfer, pregnancy monitoring and early pregnancy care. Every step requires professional guidance and support from doctors. With the continuous development and improvement of IVF technology, more couples can achieve their fertility aspirations.
