Does smoking cause problems with IVF?
Smoking is a common bad habit, but for IVF, smoking may have a negative impact on its health and development. The potential problems of smoking on IVF are described in detail in the following four aspects.
Affects pregnancy probability and success rate
First, smoking will significantly affect the pregnancy rate and success rate of IVF. Research shows that smokers are more likely to have embryo implantation failure, slow embryo development, early abortion and other situations than non-smokers. The harmful substances in tobacco will hinder the proper implantation of embryos in the uterus, and affect the division and development of embryonic cells, leading to abnormal embryonic development and increasing the risk of early abortion.
In addition, the quality and quantity of eggs will also be significantly affected when smoking women receive assisted reproductive technology. The study found that the quality of smokers' eggs was relatively poor, and the risk of chromosomal abnormalities and gene mutations in infants was higher. These factors will directly affect the success rate of IVF treatment.
In conclusion, smoking can significantly reduce the pregnancy probability and success rate of IVF, and increase the risk of early abortion and abnormal embryonic development.
Increased risk of developmental abnormalities in infants
Smoking also increases the risk of postnatal developmental abnormalities in test tube babies. The study found that infants born to smokers are more likely to suffer from congenital malformations than non-smokers. The harmful substances in smoking enter the maternal circulatory system and are transported to the fetus through blood, affecting the development of its organs and tissues.
It is particularly noteworthy that babies born to smokers may suffer from severe congenital malformations such as cleft lip and palate, heart defects, neural tube defects, etc. Once these abnormalities occur, they will have a long-term impact on the health and quality of life of infants.
Therefore, in order to reduce the risk of IVF malformation, prospective parents should stop smoking during the preparation period to increase the growth and health quality of IVF.
Influence the cycle and success rate of embryo transfer
Smoking also affects the cycle and success rate of embryo transfer. When smokers receive IVF treatment, it may take longer to reach the appropriate cycle of embryo transfer. Studies have found that smoking can reduce endometrial blood flow and affect the chances and success rate of embryo implantation. In addition, smoking will also reduce the thickness of the endometrium, reducing the space and conditions for embryo implantation.
During embryo transfer, poor blood circulation and unsuitable intrauterine environment will increase the risk of embryo implantation failure. Therefore, smokers should follow the guidance of doctors during IVF treatment and try to quit smoking to improve the success rate of embryo transfer.
Summary
The potential problems of smoking on IVF are mainly reflected in four aspects: affecting the probability of pregnancy and success rate, increasing the risk of infant malformation, and affecting the cycle and success rate of embryo transfer. Smoking will reduce the success rate of IVF pregnancy and increase the risk of early abortion and abnormal embryonic development; It also increases the risk of postnatal developmental abnormalities; In the process of embryo transfer, smoking will affect the intrauterine environment and reduce the success rate of embryo implantation. Therefore, in order to improve the health and success rate of IVF, prospective parents should try their best to avoid smoking during pregnancy preparation and treatment.
