What are the contraindications of IVF
The development of IVF technology has brought fertility hope to many infertile couples. However, not all infertile couples are suitable for IVF technology, because IVF also has some contraindications that need attention. Next, we will elaborate on the contraindications of IVF in terms of age, physical condition, sperm quality and genetic disease.
Age
For women, age is one of the important factors that affect the success rate of IVF and fetal health. Generally speaking, when a woman is over 40 years old, her ovarian function will gradually decline, and the quality and quantity of eggs will also decrease, thus reducing the probability of success of IVF. Therefore, for couples whose female age is over 40, IVF may not be an ideal choice.
In addition, for couples whose women are too young, the applicability of IVF should also be carefully considered. Because the ovarian function of young women may not be fully developed, the quality and quantity of eggs may not be enough to support the success of IVF.
In conclusion, age is one of the important factors affecting the applicability of IVF. Women between 35 and 40 years old are suitable to try IVF technology, while couples who are too young or too old need to consider carefully.
Physical condition
In addition to age, the physical condition of the couple will also affect the applicability of IVF. First, women should ensure that they are healthy and free from serious chronic diseases and organ dysfunction. For example, women with serious heart disease or kidney disease are generally not recommended for IVF. In addition, women should ensure that the uterus and pelvic conditions are normal, and there are no abnormalities affecting pregnancy such as uterine malformations and ovarian cysts.
Similarly, men also need to maintain good physical condition. Semen quality is one of the important factors that determine the success of IVF. Men should maintain a healthy lifestyle and avoid bad habits such as excessive drinking and smoking. In addition, men need to ensure that the quantity and quality of sperm in semen reach a normal level in order to improve the success rate of IVF.
In general, physical condition is one of the important factors that determine the applicability of IVF. Couples should first ensure that their health conditions meet the requirements of IVF.
Sperm quality
IVF requires sperm for IVF, so the quality of male sperm is one of the important factors affecting the success of IVF. The quality of sperm includes its vitality, shape and quantity. If sperm activity is weak, even in vitro fertilization is difficult to succeed; If sperm morphology is abnormal, it may also affect embryo quality and implantation ability; Too few sperm will also reduce the success rate of IVF.
Therefore, for men with poor sperm quality, IVF may not be an ideal choice. At this time, couples are advised to seek other assisted reproductive technologies or choose other suitable reproductive methods.
Hereditary disease
If one or both of the couples has a genetic disease, IVF may need special treatment. On the one hand, IVF can screen chromosome abnormalities and genetic diseases of embryos through embryonic genetic diagnosis technology (PGD) to avoid transmission of genetic diseases. On the other hand, couples can also choose artificial insemination or surrogacy to avoid the risk of transmission of genetic diseases.
Before choosing the IVF technology, couples should first carry out gene testing to find out whether they carry gene mutations of genetic diseases. If necessary, you can consult a genetic consultant to better understand the genetic risks and choose a suitable birth mode.
Summary
Test tube baby technology is widely used in infertile couples, but not all couples are suitable for this technology. According to age, physical condition, sperm quality, genetic disease and other factors, we know that IVF has many contraindications. Therefore, when choosing IVF technology, couples should first carry out a comprehensive physical examination and genetic testing, and at the same time, under the guidance of professional doctors, consider their own conditions and needs comprehensively to choose a suitable birth mode.
