In vitro fertilization (IVF) is a common term for in vitro fertilization-embryo transfer technology, which refers to the artificial method of fertilizing eggs and sperm outside the body and then transferring them to the uterus for development and birth. This process mainly includes promoting and monitoring follicle development, egg retrieval, sperm retrieval, in vitro fertilization, embryo transfer, and other steps.

Specifically, doctors first use medication to induce ovulation to obtain a larger number of egg cells for use, and monitor follicle development by measuring follicle diameter and determining estradiol and progesterone levels through B-mode ultrasound. When the follicles are mature but not yet ruptured, the doctor will use a fine needle to puncture the mature follicles guided by B-mode ultrasound, through the abdominal or vaginal puncture to extract follicular fluid to find egg cells. Meanwhile, sperm retrieval will also be performed under sterile conditions.

Subsequently, the retrieved egg cells will be cultured in a culture medium to further mature them to a state close to ovulation. After a period of cultivation, these egg cells will be mixed with processed sperm for fertilization. After a certain period of cultivation, the doctor will observe whether there are two pronuclei appearing, indicating successful fertilization of the egg.

When the fertilized egg develops into 8-16 cells, the doctor will use a catheter to inject the blastocyst into the mother’s uterine cavity for embryo transfer. Subsequently, the embryo will continue to develop in the mother’s uterus until the final delivery.

Since the birth of the first test-tube baby in 1978, human assisted reproductive technology IVF has undergone more than 40 years of development. Now, this technology has become increasingly mature and is rapidly developing. Thousands of couples have obtained their healthy babies with the help of IVF technology. In recent years, some large-scale surveys and studies worldwide have shown no differences in birth defects, physiological development, intelligence, etc., between offspring born through IVF technology and those born through natural conception. So far, about 5 million third-generation IVF babies have been born in the world, and the first batch of babies born through IVF technology have grown up and given birth to healthy babies.

You can seek the help of third-generation IVF in the United States if you have the following conditions:
※ Tubal infertility
※ Endometriosis
※ Male factors leading to infertility
※ Ovulation disorders
※ Immunological infertility
※ Unexplained infertility
