Test tube baby: the influence of smoking on fertility success rate
Test tube baby technology is a reproductive medicine technology that has attracted much attention in recent years. It has brought hope to many couples who cannot conceive naturally. However, some bad living habits, such as smoking, may have a certain impact on the fertility success rate of IVF. This article will elaborate on the influence of smoking on IVF from many aspects.
1. The decline of egg quality
Smoking has obvious adverse effects on female reproductive system. The study found that smoking led to a decline in egg quality, especially for older women. Nicotine and other harmful substances in tobacco will interfere with the normal development process of eggs, resulting in decreased egg quality.
First of all, harmful substances in tobacco can cause eggs to produce free radicals, destroy cell structure and function, thus reducing the viability and fertilization ability of eggs. Secondly, smoking will interfere with the normal cycle of eggs, so that eggs are discharged too early or too late, increasing the difficulty of pregnancy. Finally, smoking can also lead to abnormal egg chromosomes, increase the risk of abnormal embryonic development, and reduce the success rate of pregnancy.
Therefore, for couples preparing for IVF, women should try to quit smoking to improve the quality of eggs and increase the fertility success rate of IVF.
2. Deterioration of uterine environment
Smoking not only affects the quality of women's eggs, but also adversely affects the uterine environment. The uterus is an important place for embryo implantation and development, and its health has a direct impact on the success rate of IVF. Smoking will cause changes in the endometrium and increase the difficulty of embryo implantation.
First, the harmful substances in tobacco will reduce the blood supply of endometrium, reduce the transmission of nutrients and oxygen, and affect the survival and growth of embryos. Secondly, smoking can also lead to abnormal blood coagulation function of endometrium, increasing the risk of embryo implantation failure. Finally, harmful substances in tobacco may interfere with the hormone balance of endometrium, affect the thickness and quality of endometrium, thus reducing the success rate of embryo implantation.
Therefore, for couples who want to have IVF, women should try to avoid smoking, so as to maintain a good uterine environment and improve the fertility success rate of IVF.
3. The decline of sperm quality
Smoking not only has a negative impact on women's reproductive system, but also has a negative impact on men's sperm quality. Research shows that smoking will lead to a decline in the number and quality of sperm, thus affecting the success rate of IVF pregnancy.
The harmful substances in tobacco will directly enter the blood circulation of men and have toxic effects on testes and sperm. Nicotine will affect the viability and mobility of sperm, making it unable to fully participate in the fertilization process. In addition, smoking can also lead to abnormal sperm morphology and DNA damage, increasing the risk of embryo malformation.
In order to improve the success rate of IVF, men should also try to stay away from tobacco and reduce the negative impact of smoking on sperm quality.
4. Treat smoking rationally
Although smoking has a negative impact on the success rate of IVF, not all smokers will cause fertility problems. Everyone has different physical conditions and smoking habits, so the impact of smoking on IVF may be different. However, on the whole, smoking cessation is still very important for improving the fertility success rate of IVF.
To sum up, smoking has a negative impact on the fertility success rate of IVF. Smoking will reduce the quality of eggs and sperm, worsen the uterine environment, thus increasing the difficulty of embryo implantation and development. Therefore, couples should keep away from tobacco as far as possible before preparing for IVF, so as to improve the possibility of fertility success.
