Definition and development of IVF
In vitro fertilization (IVF) is a kind of reproductive technology, by fertilizing the egg and sperm in vitro, and then implanting the embryo into the female uterus, so that it can continue to develop into a baby. Since the first successful birth of IVF in 1978, IVF has become one of the important means to solve the problem of infertility.
The development of IVF has gone through several key steps. First, the preparation of eggs and sperm. Through hormone therapy to assist ovarian ovulation, doctors can obtain more mature eggs. At the same time, sperm samples provided by men were collected.
The second step is in vitro fertilization and culture. Put the obtained eggs and sperm into the culture dish, and let them fertilize and combine under specific environmental conditions. Then, the embryos were cultured until they reached the stage of implantation into the uterus.
The third step is to implant the embryo into the uterus. Doctors place a thin tube in a woman's uterus, through which the embryo is implanted. After implantation, the embryo will continue to develop, embed in the uterus, and eventually become a baby.
Applicable population and process of IVF
IVF is mainly applicable to the following groups: women with infertility diseases such as tubal obstruction and polycystic ovary syndrome; The male suffers from infertility caused by low sperm number or motility, inability to ejaculate normally and other causes; Both husband and wife have infertility or infertility problems.
The whole process of IVF is usually divided into five steps. First of all, women should receive hormone therapy to promote ovarian ovulation, and at the same time, they should receive regular ultrasound examination. The second step is to collect female eggs. This process uses minimally invasive technology to extract eggs under the guidance of ultrasound.
Next, collect male sperm. The men provided fresh sperm samples or pre frozen sperm samples the next day. Doctors then fertilize eggs and sperm in vitro. After 48-72 hours of culture, multiple embryos were formed.
Finally, the doctor will select one or more embryos through thin tubes into the female uterus. After that, doctors monitor that if the embryo is successfully implanted, pregnancy will begin.
Success rate and risk of IVF
The success rate of IVF is affected by many factors, including age, egg and sperm quality. According to data statistics, the success rate of young women is relatively high, and that of women over 35 will decline significantly.
However, IVF also has some risks. The first is multiple pregnancy, that is, multiple embryos implanted are successfully implanted, resulting in twins or multiple births. Multiple pregnancy brings certain risks to both pregnant women and fetuses, including premature delivery, growth retardation, etc.
In addition, IVF also has a certain risk of complications, such as ovarian hyperstimulation syndrome, bleeding, etc. Therefore, before IVF, doctors will conduct a comprehensive assessment of patients to determine their applicability and inform them of potential risks.
Related hospitals and effects of IVF
There are many famous IVF hospitals around the world. Among them, Cleveland Clinic in the United States, London Fertility Clinic in the United Kingdom, Sydney IVF Center in Australia and so on are all renowned IVF specialist hospitals.
These hospitals have advanced technology and equipment, and experienced expert teams, which can provide comprehensive services for infertile patients. Through IVF technology, it has successfully helped tens of thousands of couples realize their dreams of childbearing.
summary
The development of IVF technology provides a feasible solution for infertile couples. Through in vitro fertilization and embryo implantation, it brings hope to couples who cannot conceive naturally.
However, IVF is not perfect, and there are certain risks and limitations. Before deciding to try IVF, patients should consider their own conditions comprehensively and make decisions under the guidance of doctors.
