Applicants of the first generation IVF technology
Test tube baby technology is an important reproductive medicine technology, which aims to help couples who cannot conceive naturally realize their reproductive aspirations. The first generation of IVF technology came out in the 1980s. After years of development, it has become a relatively common and safe assisted reproductive technology. The following will elaborate on the population applicable to the first generation of IVF technology from the perspectives of age, infertility causes, female uterus and male sperm quality.
1. Age
IVF technology is applicable to women between the ages of 20 and 40. In the female reproductive system, the quality and quantity of eggs will gradually decline with age. The incidence of infertility will gradually increase with age. Therefore, for women under 40 years old, IVF technology is an effective way to treat infertility.
However, age is not an absolute limiting factor. For women over 40 years old, although the risk of egg quality and quantity decline is greater, it is still possible to successfully conceive through IVF technology. The doctor will evaluate according to the specific situation of women and provide corresponding suggestions.
2. Causes of infertility
The IVF technology is applicable to a variety of infertility causes. Infertility can be caused by many factors, including female, male and bilateral factors. Common female factors include fallopian tube obstruction, polycystic ovary syndrome, etc., while male factors mainly include poor sperm quality, semen abnormalities, etc. At the same time, some infertility can not be clearly attributed to men or women, which is called non-specific infertility.
For different reasons of infertility, IVF technology can adopt different assisted reproduction methods. For example, if the fallopian tube is blocked, IVF can be used; In the case of poor quality of male sperm, the IVF technology can be used to combine sperm and egg, and then transfer the fertilized egg to the female uterus for pregnancy.
3. Female uterus
IVF technology is applicable to women with normal uterine conditions. The female uterus is an important organ for breeding new life. If there are uterine abnormalities, such as uterine hypoplasia, endometriosis and other problems, it will have adverse effects on embryo implantation and development.
In IVF technology, the health of the female uterus is one of the key factors for the success of pregnancy. Therefore, before IVF technology, doctors usually check women's uterus to ensure that it is in good health.
4. Male sperm quality
IVF is suitable for patients with poor sperm quality. The quality of male sperm directly affects the success rate of fertilization and the development of embryos. Common factors affecting sperm quality include sperm quantity, motility, morphology, etc.
When there is a problem with the quality of male sperm, assisted reproduction methods can be used through IVF technology, such as selecting sperm with good sperm quality for in vitro fertilization, or directly injecting sperm into eggs through single sperm injection technology.
In conclusion, the first generation IVF technology is applicable to women between the ages of 20 and 40, patients with different infertility causes, women with normal uterine conditions, and men with poor sperm quality. For these people, IVF technology is a safe and effective assisted reproduction method, which can help them achieve their reproductive aspirations.
