Indications of the third generation IVF
The third generation IVF technology is one of the assisted reproductive technologies, which is mainly used for couples who cannot conceive naturally due to reproductive system diseases or other problems. It achieves pregnancy by combining eggs and sperm and forming embryos in the process of in vitro culture, and then implanting the embryos into the mother's uterus. The following are the indications of the third generation IVF.
1. Fallopian tube disease
The fallopian tube is an important passage for eggs from the ovary to the uterus. If the fallopian tube is damaged or blocked, the eggs cannot pass through the fallopian tube to the uterus smoothly. Fallopian tube disease is one of the common causes of infertility. For these patients, the third-generation IVF technology provides a solution. After in vitro fertilization sperm and eggs are cultured into embryos, doctors can directly implant the embryos into the uterus to avoid damaged fallopian tubes and improve the chance of pregnancy.
In addition, through the third generation IVF technology, doctors can also choose to implant embryos into normal fallopian tubes, thereby reducing the risk of re pregnancy. In some cases, if the fallopian tube is damaged at the same time and cannot be repaired, the doctor can recommend a woman to carry out a uterine transplant to transfer the embryo to another person's uterus.
2. Low sperm quality or quantity
The quality and quantity of sperm are crucial to pregnancy. For men with low sperm quality or quantity, the chance of natural pregnancy is greatly reduced. The third generation IVF technology increases the chance of pregnancy by selecting high-quality sperm in vitro culture. Doctors can select high-quality single sperm to inject into eggs through a series of auxiliary methods, such as sperm injection technology (ICSI). This can greatly improve the success rate of pregnancy.
In addition, for those men who do not have the ability to produce sperm, we can consider using donated sperm for the third generation of IVF. Doctors can combine the donor's sperm with a woman's egg, grow it into an embryo in the laboratory, and then implant the embryo into the mother's uterus.
3. Female infertility
Female infertility refers to infertility caused by abnormal ovarian function, egg quality problems or other gynecological diseases. The third generation IVF technology can help these patients achieve their dream pregnancy. In this process, doctors can assist the development of eggs through ovulation promoting drugs, and then collect eggs at an appropriate time. Next, the doctor will combine the collected eggs with sperm, cultivate them into embryos in the process of in vitro culture, and finally implant the embryos into the uterus for pregnancy.
4. Hereditary diseases
For couples with certain genetic diseases, natural pregnancy may bring risks, because these diseases may be passed on to offspring. The third generation IVF technology provides a choice, that is, screening healthy embryos through genetic screening and embryo gene testing. In this way, embryos that do not carry genetic diseases can be selected for implantation to reduce the risk of transmission of genetic diseases.
In summary, the third generation IVF technology is applicable to fallopian tube diseases, low sperm quality or quantity, female infertility and genetic diseases. Through this technology, many infertility problems can be solved, and couples have the opportunity to realize their reproductive dreams.
