Overview of IVF technology
IVF technology is a kind of assisted reproductive technology, which aims to help couples who cannot conceive naturally achieve their reproductive aspirations. By combining the egg and sperm in the laboratory, and then transplanting the fertilized egg into the female uterus, it can promote its successful implantation and development. IVF technology has made great progress, including in vitro fertilization, intracavitary injection and embryo transfer.
Types of IVF technology
1. In vitro fertilization (IVF)
In vitro fertilization is one of the most common IVF technologies. This technique combines female eggs with male sperm in the laboratory to form a fertilized egg. After a few days of development of the fertilized egg in the culture dish, one or more of the embryos are selected and transferred to the uterus of the female, promoting pregnancy.
2. Intraparietal injection (ICSI)
Intraapical injection is a more sophisticated in vitro fertilization technology. In this technique, a single sperm is injected into an egg to increase the success rate of fertilization. Acrosome injection is applicable to the condition that the male is difficult to conceive due to insufficient sperm quantity, quality or mobility.
3. Embryo transfer
Embryo transfer is the last step of IVF technology. After in vitro fertilization or intracavitary injection, multiple embryos are cultured in the laboratory, and one or more of them are most likely to successfully develop into embryos and then be transplanted into the female uterus. The remaining embryos can be frozen for future use.
Indications of IVF technology
1. Ectopic pregnancy
Ectopic pregnancy refers to the implantation of fertilized eggs outside the uterus, usually in the fallopian tube. IVF technology can help deal with this situation and improve the chances of successful pregnancy and safe pregnancy.
2. Male infertility
Male factor infertility includes abnormal sperm quantity and quality, or inability to ejaculate normally. IVF and IVI can provide a solution to improve the possibility of pregnancy by injecting sperm directly into the egg.
3. Ovarian dysfunction
Ovarian dysfunction may lead to abnormal or insufficient egg development. In vitro fertilization technology can help achieve pregnancy by obtaining healthy eggs from female donors or frozen egg banks and combining them with male sperm for in vitro fertilization.
Summary
Test tube baby technology is a major breakthrough in modern medicine, providing opportunities for couples who cannot conceive naturally. IVF, IVI and embryo transfer are common IVF technologies. Indications include ectopic pregnancy, male infertility and ovarian dysfunction. Although the IVF technology can realize the fertility desire, the situation of each couple is different, and the IVF technology suitable for themselves should be selected under the guidance of professional doctors.
