What is IVF test tube baby?
In vitro fertilization (IVF) refers to an assisted reproductive technology that combines female eggs and male sperm into fertilized eggs in the laboratory, and then implants the fertilized eggs into the female uterus to promote pregnancy. The invention and application of IVF test tube baby technology provide hope for couples who cannot conceive naturally to realize their dreams and become parents.
Steps and methods of IVF
The specific steps of IVF usually include the following stages:
The first is hormone therapy: women can promote ovarian ovulation and increase the number of eggs produced by injecting hormone.
The second is to collect eggs: the doctor will collect the eggs discharged from the ovary by vaginal puncture under the guidance of ultrasound, and then send them to the laboratory for processing.
The third is sperm egg retrieval: men need to provide sperm samples to doctors, who will extract active sperm through centrifugation and washing technology.
The fourth is in vitro fertilization: the collected eggs and sperm are placed in a culture dish for laboratory fertilization.
The fifth is embryo culture: the fertilized egg is cultured in a culture dish until it develops into an embryo.
The sixth is embryo transfer: put the cultured embryo into the female uterus through the vagina, waiting for the result of pregnancy.
intended for
IVF technology is mainly applicable to the following populations:
Infertile couples: including couples who have difficulty in natural pregnancy due to female ovarian dysfunction, abnormal or damaged fallopian tubes, and male sperm quality problems.
Couples with genetic diseases: Both couples carry genes of serious genetic diseases. In order to prevent inheritance to offspring, embryo genetic diagnosis and screening can be carried out through test tube baby technology.
Older women: The ovarian function of women gradually declines with age. IVF technology can help older women increase the success rate of pregnancy.
Success rate and risk
The success rate of IVF technology is related to many factors, including women's age, the quality of eggs and sperm, and the effect of hormone therapy. According to statistics, the probability of a successful IVF is usually between 30% and 40%.
Although IVF technology can help couples who are unable to conceive naturally achieve their reproductive aspirations, it also has certain risks. For example, hormone therapy may cause ovarian hyperstimulation syndrome, and abortion, ectopic pregnancy and other complications may occur after embryo transfer.
Therefore, when choosing IVF test tube babies, couples should choose regular hospitals and experienced doctors for treatment, and actively cooperate with doctors' suggestions and guidance to improve the success rate and reduce risks.
summary
IVF is an assisted reproductive technology that helps couples who cannot conceive naturally to achieve fertility through in vitro fertilization. The technology specifically includes hormone therapy, egg and sperm collection, in vitro fertilization, embryo culture, embryo transfer and other steps. It is suitable for infertile couples, couples with genetic diseases and older women. Although the success rate of IVF technology is limited, there is still a chance to become a parent on the premise of choosing a regular hospital and actively cooperating with doctors. However, we should also pay attention to the risks caused by hormone therapy, and weigh the advantages and disadvantages when making decisions. IVF technology provides a way for infertile couples to realize their dreams of childbirth.
