Definition of IVF
In vitro fertilization (IVF) refers to the process of combining sperm and eggs in the laboratory through IVF or other assisted reproductive technologies, so that the pregnancy process can be completed in vitro, and then the embryo can be transferred to the mother's uterus for pregnancy and delivery. This technology allows couples who are unable to conceive naturally for various reasons to have the opportunity to realize their reproductive dreams.
In order to realize IVF technology, a series of steps are required. First, the woman received ovulation promoter treatment to produce multiple eggs. Then, the doctor will collect the woman's eggs at an appropriate time. At the same time, the man provides sperm samples, and then combines sperm and eggs in the laboratory to form an embryo. Generally, multiple embryos can be cultured to the age of five days to select the best embryos for transplantation. The remaining embryos can be frozen for future use.
IVF technology has been widely used in the world, and has been regarded as a conventional means of fertility treatment in many countries. The following will elaborate on the relevant contents of IVF from the aspects of treatment scope, hospital selection, preparation process and success rate.
Scope of IVF treatment
IVF technology is applicable to infertility caused by many different causes. It can be used for the treatment of women's oviduct obstruction, polycystic ovary syndrome, endometriosis and other diseases. Similarly, IVF technology can also help men with infertility caused by substandard sperm quality or quantity. In addition, whether men or women, if they try to have a natural birth for more than one year and fail, they can consider IVF technology for treatment.
Select the right hospital
Choosing a professional and experienced hospital is particularly important for IVF treatment. Priority should be given to hospitals with relevant specialized teams and modern facilities. For example, Peking Union Medical College Hospital and Ruijin Hospital affiliated to Shanghai Jiaotong University School of Medicine in China have rich experience and technical strength in the field of IVF.
When choosing a hospital, the success rate and treatment cost of the hospital should also be considered. The success rate can be assessed by understanding the hospital's past cases and patient feedback. The treatment cost will vary due to the geographical location, technical level and other factors of the hospital. It is necessary to consult with the hospital in detail and make a reasonable choice based on its own economic situation.
Preparation of IVF
The preparation process of IVF usually includes the following steps:
1. Women's ovulation promotion treatment: drugs are usually used to promote the development and maturation of follicles. The doctor will make a practical treatment plan according to the individual situation.
2. Ovarian stimulation and egg collection: use drugs to stimulate ovarian development, so that it can develop multiple follicles at the same time. Then, at an appropriate time, the eggs are collected through puncture or ultrasound guided transvaginal ovarian puncture.
3. Sperm extraction and combination: The man provides a sperm sample, and then combines with the egg in the laboratory to form a fertilized egg.
4. Embryo culture and selection: Cultivate the fertilized egg to the age of five days, evaluate its development and quality, and select the best embryo for transplantation. The remaining embryos can be frozen.
5. Embryo transfer: Place the selected embryo into the uterus through uterine cavity puncture for pregnancy and delivery.
Success rate of IVF
The success rate of IVF is affected by many factors, including age, disease status, treatment methods, etc. Age is one of the most important factors affecting the success rate. The older the female, the lower the success rate. According to data statistics, the success rate of IVF for women under 30 years old can reach about 40% to 50%, while the success rate for women over 40 years old may only be 10% to 20%.
In addition to age, other medical conditions may also affect the success rate. On the whole, the success rate of IVF is increasing year by year, and the continuous progress of medical technology has enabled more and more couples to achieve the desired parent-child relationship.
Summary
As an assisted reproductive technology, IVF provides a hope for couples who cannot conceive naturally. Through in vitro fertilization technology, doctors can help patients realize their reproductive dreams. Choosing a suitable hospital, the smooth preparation process and understanding the influencing factors of the success rate are all important links to ensure the success of IVF treatment. In the future, with the continuous development of medical technology, IVF technology will also continue to improve, bringing good news to more infertile couples.
