Indications for IVF
IVF technology is a kind of assisted reproductive technology, which can help couples who cannot conceive naturally achieve their reproductive aspirations. The following are some common indications for IVF:

1. Infertility caused by oviduct factors
The fallopian tube is the place where eggs and sperm combine, but some women may be infertile due to abnormal structure, obstruction or excision of the fallopian tube. IVF technology can help these patients achieve pregnancy. First, the doctor will use ultrasound and other methods to check the patency of the fallopian tube. If the fallopian tube cannot be unblocked normally, the doctor will recommend the use of IVF technology.
For infertility caused by fallopian tube factors, in vitro fertilization embryo transfer (IVF-ET) is the most commonly used IVF technology. Through the combination of eggs and sperm in the laboratory, the embryos are cultured and transferred to the female uterus for development.
2. Male fertility
Male problems are also one of the common causes of infertility. If men have problems such as insufficient sperm quantity, low sperm vitality and poor semen quality, IVF technology can be used as a solution.
For male fertility, IVF-ET, ICSI and PICSI can be used in IVF technology. These methods can maximize the success rate of fertilization.
3. Ovarian dysfunction
Some women cannot conceive naturally due to ovarian dysfunction, such as early menopause, polycystic ovary syndrome, etc. In this case, IVF technology can play a role in helping.
In IVF technology, doctors may use assisted reproductive technology (ART) methods, such as egg donation, egg freezing, etc. Egg donation can obtain eggs from healthy women, and then fertilize them with her husband's sperm. However, egg freezing can delay women's reproductive age and increase their chances of pregnancy.
4. Prostate problems and semen abnormalities
Male prostate problems and semen abnormalities also often lead to infertility. Prostate problems may lead to abnormal sperm discharge, and semen abnormalities may affect the quality and quantity of sperm.
In view of this situation, the methods that can be used in IVF technology include: in vitro fertilization embryo transfer (IVF-ET), single sperm microinjection (ICSI) and sperm cryopreservation. These methods can solve the problem of sperm discharge and improve the success rate of fertilization.
Summary
IVF technology is a kind of assisted reproductive technology, which can help couples who cannot conceive naturally to achieve their reproductive aspirations. According to the specific conditions of patients, doctors can choose the appropriate IVF technology. Infertility caused by fallopian tube factors, male fertility problems, ovarian dysfunction, prostate problems and semen abnormalities are common indications for IVF. By using IVF technology, couples can overcome fertility barriers and realize their wishes. Please note that when choosing IVF technology, patients should consult professional doctors, comprehensively evaluate various factors, and formulate the most suitable treatment scheme for themselves.
