Applicable population of IVF
In recent years, IVF technology has been widely used in the world as a reproductive assistance technology. It provides infertility couples with the opportunity to achieve fertility through assisted pregnancy medical means. However, not all infertile couples are suitable for IVF technology, and its application scope is limited. The following will elaborate on the applicable population of IVF from many aspects.

1. Infertility couples caused by physiological barriers
IVF technology is applicable to infertile couples caused by male and female physiological disorders. For men, such as the low quality of semen and the inability of sperm to enter the female uterus naturally, IVF technology can directly use semen or extract sperm, and then transfer the fertilized eggs to the female uterus through in vitro fertilization, thus increasing the chance of pregnancy.
For women, IVF technology is applicable to a variety of physiological disorders, such as fallopian tube obstruction, polycystic ovary syndrome, endometriosis, endometrial polyps, etc. These problems will lead to the failure of natural implantation or development of the fertilized egg. The IVF technology can solve these problems in the process of IVF and improve the success rate.
In addition, IVF technology is also applicable to infertile couples who cannot be solved by other assisted reproductive technologies. The IVF technology can become the last means of pregnancy aid as long as the physiological barriers of both men and women cannot continue to reproduce through other methods.
2. Couples with high risk of genetic diseases or chromosomal abnormalities
If there is a risk of genetic diseases or chromosomal abnormalities in couples, IVF technology can help couples screen healthy embryos for transplantation, thus reducing the risk of genetic diseases or chromosomal abnormalities to the next generation.
For example, if one of the couples has an autosomal dominant genetic disease, there is a 50% probability that the diseased gene will be passed on to the next generation. Through IVF technology, gene detection can be carried out at the early stage of the embryo, that is, within a few days after the formation of the fertilized egg, and embryos with normal diseased genes can be screened for transplantation, so as to avoid passing on genetic diseases to future generations.
Similarly, the risk of chromosomal abnormalities in couples, such as chromosomal translocation and abnormal chromosome number, can also be prevented and reduced through IVF technology. This is especially applicable to couples whose chromosome abnormalities lead to repeated abortions.
3. Older women
With the growth of women's age, the ovarian function gradually declines, and the quality and quantity of eggs will also decrease, thus affecting the chances of pregnancy and embryonic development. Therefore, IVF technology is applicable to older women and can provide better fertility opportunities.
Some women over 30 years old who have the desire to have children cannot conceive naturally due to other reasons can choose IVF technology to achieve fertility through in vitro fertilization and embryo transfer. The IVF technology can use fresh eggs or frozen eggs. However, the ovarian function of elderly women declines rapidly, and the quality of frozen eggs may be poor, so the success rate of using fresh eggs is high.
4. Couples with family infertility history
In the case of multiple infertility cases in the family, IVF technology can provide better opportunities for infertile couples to help them conceive. Some infertility diseases have a genetic tendency. The IVF technology can bypass these obstacles and meet the reproductive needs of infertile couples.
For example, there are many cases of congenital malformations or infertility in the reproductive system of a great grandfather, grandfather or one of the brothers and sisters. In the context of this family infertility history, IVF technology can provide better fertility opportunities for couples.
Summary
IVF technology is applicable to infertile couples caused by physiological disorders, couples at risk of genetic diseases or chromosomal abnormalities, older women and couples with a family history of infertility. Under these circumstances, IVF technology can provide better fertility opportunities and help infertile couples realize their fertility dreams.
