Can smoking reduce the success rate of IVF?
In recent years, with the progress of science and technology, IVF technology has become the hope of many infertile couples. However, the success rate has also become one of the most concerned issues. Many studies have shown that smoking has an important impact on the success rate of IVF. Next, we will analyze the influence of smoking on the success rate of IVF from the aspects of health, egg quality, fertilization rate and embryo development.
good health
Smoking will have a negative impact on health, and health is one of the important factors for IVF success rate. Harmful substances released during smoking can cause vasoconstriction, leading to insufficient oxygen supply. This is very unfavorable for embryo implantation and maternal pregnancy. In reproductive medicine, good blood circulation and adequate oxygen supply are the basis to ensure the smooth development of IVF.
In addition, nicotine in tobacco can also increase heart rate and blood pressure, increase cardiovascular burden, and affect the normal metabolic function of the body. Smoking will also lead to the reduction of oxygen in the blood, resulting in hypoxia of embryonic cells, thus affecting the quality and quantity of embryonic development.
Therefore, physical health is an important factor in determining the success rate of IVF. Smoking will directly reduce the health status of the body, thus affecting the success rate of IVF.
Egg mass
In the process of IVF, egg quality is a key link. Smoking will have a direct impact on women's egg quality. Research shows that smoking can lead to the decline of ovarian function and egg quality. The number of eggs of smokers will decrease, and the quality of eggs will also be affected.
Nicotine and other harmful substances will accumulate in the ovary, affecting the normal development and maturation of eggs. This makes the fertilization ability of eggs decline and the difficulty of implantation increase. In addition, chemicals in tobacco can also lead to abnormal egg chromosomes, increasing the risk of genetic diseases during embryonic development.
Therefore, smoking will have a direct negative impact on egg quality and reduce the success rate of IVF.
Fertilization rate
Smoking will affect the success rate during fertilization, thus reducing the success rate of IVF. Research shows that smoking will affect the quality and quantity of men's sperm, thus affecting the fertilization rate.
The harmful substances in tobacco can lead to abnormal morphology, decreased number and decreased vitality of sperm. All these factors will affect the chance that sperm can successfully combine with eggs. In addition, smoking will also increase the DNA damage of sperm, which will affect the embryonic development after fertilization.
Therefore, smoking will directly affect the success rate in the process of fertilization, thereby reducing the success rate of IVF.
embryonic development
Smoking also has an important impact on the development of embryos. Research shows that smoking will have a negative impact on the speed and quality of embryo development.
The lack of oxygen and nutrient supply caused by smoking will affect the cell division and development of the embryo, resulting in slower or abnormal development of the embryo. In addition, the accumulation of harmful substances will also have toxic effects on embryonic cells, affecting the normal development of embryos.
Therefore, smoking will directly affect the development of embryos and reduce the success rate of IVF.
Summary
Smoking has an important influence on the success rate of IVF. Health, egg quality, fertilization rate and embryo development will be negatively affected by smoking. Therefore, not only a reasonable treatment plan and medical means are needed, but also early smoking cessation is needed to ensure the health of the body and eggs and improve the success rate of IVF.
