Steps of the second generation IVF

In vitro fertilization (IVF) is an assisted reproductive technology, which combines eggs and sperm artificially and cultivates them to the embryonic stage, and then implants the embryos into the mother's uterus to achieve pregnancy. With the development of science and technology, IVF technology has also made continuous progress, giving birth to the second generation of IVF technology. The key steps of the second-generation IVF will be described in detail below.

1. Ovulation promotion process

Ovulation induction is the first step of the second generation IVF. In this process, doctors will use drugs to stimulate women's ovaries, increase the number of follicles and egg quality. The whole process of ovulation induction usually takes about 10-14 days. Before starting treatment, doctors will evaluate the ovarian function and follicular growth of women through ultrasound and blood tests. Then, the patient will inject drugs every day to promote the simultaneous development of multiple follicles. The doctor will conduct regular ultrasonic examination and blood test to monitor the growth of follicles.

2. Egg collection

Egg collection is the next key step of the second-generation IVF. Generally, eggs are collected when the follicle develops to a certain size. The operation was performed under painless anesthesia. Doctors use ultrasound guided slender catheter to puncture the ovary and extract mature eggs from the follicle. The collected eggs are then transferred to the laboratory for cultivation and preparation by trained and experienced embryologists.

3. Sperm preparation and fertilization

Sperm preparation is another important step of the second generation IVF. Male patients need to provide semen samples or obtain sperm through testicular sperm puncture. Then, laboratory technicians separate high-quality motile sperm through centrifugation and other steps. In the prepared sperm sample, the doctor will combine each egg with the sperm in order to fertilize successfully. The fertilized embryo will be cultured in the laboratory.

4. Embryo transfer and pregnancy

Embryo transfer is the last step in the process of second-generation IVF. The cultured embryos will be transferred into the female uterus through specific equipment, hoping to catalyze the occurrence of pregnancy. After embryo transfer, patients need to continue to take progesterone or other progesterone drugs to promote the successful implantation of embryos and the continued development of pregnancy. Pregnancy testing is usually carried out within two weeks after transplantation to determine whether pregnancy is successful. To sum up, the steps of second-generation IVF include ovulation induction, egg collection, sperm preparation and fertilization, as well as embryo transfer and pregnancy. These key steps rely on modern medical technology and laboratory equipment, and require the assistance and guidance of an experienced medical team. The birth of the second generation of IVF provides a chance for couples who have been unable to conceive naturally for many years to realize their dreams.
