How is the success rate of IVF affected?
Test tube baby is an assisted reproductive technology, which has helped many infertile couples realize their reproductive dreams. However, the success rate of IVF is not invariable, which is affected by many factors. In this article, we will elaborate on the impact of IVF success rate from the following four aspects.
Maternal age
Maternal age is one of the important factors affecting the success rate of IVF. Generally speaking, the older a woman is, the lower the quality and quantity of her eggs are, thus reducing the success rate. The success rate of IVF for women under 30 years old was higher, while that for women over 40 years old was significantly lower. This is because with the growth of age, the number and quality of female eggs decrease, which is prone to chromosomal abnormalities and increases the risk of miscarriage, malformation, etc.
In addition, age also affects the thickness of female endometrium and blood supply, which is critical for embryo implantation and growth. Therefore, for older women, the success rate is relatively low, and it is recommended to carry out IVF treatment as early as possible.
Male sperm quality
Male sperm quality also has an important impact on the success rate of IVF. The quality of sperm includes the quantity, motility and morphology of sperm. Sperm with small quantity, low activity or abnormal morphology will directly affect the fertilization ability and embryo quality, thus reducing the success rate.
For male patients with poor sperm quality, doctors may recommend the use of semen screened and processed by sperm, or sperm injection technology to increase the chances of fertilization and implantation. At the same time, male patients should also maintain good living habits, including avoiding smoking, limiting alcohol intake, and avoiding overwork, so as to improve sperm quality and the success rate of IVF.
Professional level of medical team
The professional level of the medical team is one of the key factors that determine the success rate of IVF. Professional doctors and nurses can provide comprehensive and personalized guidance in the treatment process, and formulate reasonable treatment plans for different patients.
In addition, the medical team also needs to master advanced assisted reproductive technology and be familiar with operating various instruments and equipment. They need rigorous operating skills and rich experience to ensure the smooth progress of key links such as egg retrieval, fertilization and embryo transfer, and improve the success rate of IVF.
Patient's physical health
The health status of patients will also affect the success rate of IVF. Patients with chronic diseases, immune system abnormalities, uterine malformations, etc. may reduce the probability of embryo implantation and the ability to maintain pregnancy.
Therefore, before IVF treatment, doctors usually conduct a comprehensive physical examination and screening of related diseases to understand the patient's physical condition, and then develop a personalized treatment plan. At the same time, patients also need to actively cooperate with the doctor's suggestions to maintain good physical condition, such as regular diet, moderate exercise, stress relief, etc., to improve the success rate of IVF.
Summary
The success rate of IVF is affected by many factors, including maternal age, male sperm quality, professional level of medical team and patients' physical health. Older people, poor sperm quality, low technical level of the medical team and poor physical condition will have a negative impact on the success rate of IVF. Therefore, selecting appropriate hospitals and doctors and actively adjusting their own status can help improve the success rate of IVF.
