Causes of IVF failure
IVF is a kind of assisted reproductive technology, which aims to help couples who cannot conceive naturally achieve their reproductive aspirations. However, although this technology has achieved some success, IVF also faces the risk of failure. There are many reasons for IVF failure, including physical conditions, medical procedures, physiological reactions and so on.
Inappropriate physical condition
The success of IVF is closely related to the patient's physical condition. First, age is an important consideration. When women are older than 35 years old, the quality of eggs will decline significantly, which will affect the quality and survival rate of embryos. In addition, IVF for patients with gynecological diseases such as uterine malformation, endometriosis or severe endometrial hyperplasia is also likely to lead to failure.
In addition, male sperm quality is also an important factor affecting the success of IVF. Problems such as semen density, sperm vitality and morphology may lead to a decrease in fertilization rate, thus affecting the success rate of IVF.
Therefore, before IVF, patients need to have a comprehensive physical examination to ensure that their physical conditions are suitable for this technology.
Improper medical operation
The success rate of IVF is closely related to the level of medical operation. First of all, the use of ovulation promoting drugs needs to be accurately mastered. Improper selection of drug types and doses will lead to poor egg development or failure to fully mature, thus reducing the pregnancy rate. Secondly, in the process of egg collection, the technical proficiency and operation detail will also affect the quality of eggs obtained.
In the process of IVF, embryo culture technology also plays an important role. The temperature, oxygen concentration, and composition of the culture medium in the culture tube of the embryo need to be precisely controlled to ensure the normal development of the embryo.
Therefore, the technical level and operating experience of doctors and hospitals are important factors to determine the success of IVF.
Poor physiological reaction
The physiological reaction of IVF is also one of the reasons for failure. The use of ovulation promoting drugs may cause ovarian hyperstimulation syndrome, leading to ovarian swelling, abdominal distention, nausea and other uncomfortable symptoms, affecting patients' experience and physical and mental status. In addition, after IVF embryo transfer, some patients have implantation failure, abortion and other conditions, which will also lead to IVF failure.
The adverse physiological reaction has a certain impact on the success of IVF, so patients need to pay attention to their own diet and rest during IVF under the guidance of doctors to reduce the body's discomfort.
summary
There are many reasons for IVF failure, including unsuitable physical condition, improper medical operation, adverse physiological reaction, etc. Therefore, before IVF, patients need to have a comprehensive physical examination to ensure that their physical conditions are suitable for this technology. At the same time, the technical level and experience of doctors and hospitals are also the key factors to determine the success of IVF. During IVF, patients should pay attention to their own diet and rest to reduce their discomfort. Through scientific operation and comprehensive nursing, it is helpful to improve the success rate of IVF. However, regardless of success or failure, patients need to actively face it and find other ways and means to achieve their reproductive aspirations.
