What infertility does IVF technology apply to?
In vitro fertilization (IVF) is an important assisted reproductive technology in the medical field. Through IVF technology, many couples who cannot conceive naturally can realize their dream of having their own children. However, not all infertility cases are suitable for IVF technology. The following will elaborate the application scope of IVF technology from four aspects: genetic factors, oviduct problems, male factors and other infertility conditions.
1. Genetic factors
Some cases of infertility are related to genetic factors, such as polycystic ovary syndrome (PCOS) and hereditary uterine malformations. PCOS is one of the most common female infertility. IVF technology can help these patients successfully conceive through ovulation and in vitro fertilization. For women with uterine malformations, the application of IVF technology can achieve pregnancy by transplanting the fertilized eggs into the uterus of the surrogate mother.
Moreover, some couples with genetic diseases may choose to avoid passing on the disease to the next generation through IVF technology. In this case, doctors will screen embryos carrying genetic disease genes through embryonic genetic diagnosis technology (PGD), and then select embryos without genetic disease genes for transplantation, so as to reduce the risk of inheriting diseases to children.
2. Fallopian tube problems
Fallopian tube problem is one of the common causes of female infertility, which may be caused by blockage, excision or ligation of fallopian tubes. With IVF technology, these patients can avoid the fallopian tube and achieve pregnancy directly. In IVF technology, women produce multiple eggs through ovulation, then take out the eggs through surgery and fertilize the sperm provided by men in vitro, and finally transfer the fertilized eggs back to the female uterus for pregnancy.
3. Male factors
Male factors are also important reasons for infertility. IVF technology is also widely used in male infertility patients. For some men with azoospermia or low quality sperm, sperm samples can be obtained through sperm extraction technology and fertilized in vitro with the eggs provided by women. Subsequently, healthy embryos were selected from the fertilized embryos and transferred to the womens uterus to achieve pregnancy.
In addition, men who have had their vas deferens removed can also achieve fertility through IVF technology. In this case, spermatozoa are obtained by direct sperm extraction, and are combined with female eggs for in vitro fertilization.
4. Other infertility
In addition to the infertility mentioned above, IVF technology is also applicable to other infertility patients who cannot be cured by other means. It includes infertility patients caused by abnormal immune system, endocrine disorder and other reasons. IVF technology provides a viable option for these patients to realize their dream of having children.
In conclusion, IVF technology is applicable to a variety of infertility conditions, including genetic factors, oviduct problems, male factors and other infertility conditions. Through IVF technology, many couples who could not have children could have their own children and realize their family dreams.
