introduction
IVF technology has become an option for many infertile couples to realize their reproductive dreams. However, with the change of living style, smoking has become one of the bad habits of many people. However, does smoking affect the success rate of IVF? This article will elaborate from many aspects. Aspect 1: Ovarian function and ovulation quality
Smoking has been proven to have a negative impact on women's ovarian function and ovulation quality. Smoking causes damage to the ovaries, reducing the number and quality of eggs. Smoking also increases the variation rate of eggs and affects the implantation ability of fertilized eggs. A study conducted by XX Hospital in southern California found that the success rate of IVF among women who smoke is only half of that of non-smokers. Therefore, female smoking will significantly reduce the success rate of IVF. In addition to affecting women's ability to conceive, smoking also affects men's sperm quality. A study conducted by a large general hospital in Hong Kong showed that the sperm density, vitality and morphology of smoking men were poor, leading to a decline in fertility. Therefore, smoking will not only affect the pregnancy probability of women, but also reduce the fertility of men.
Aspect 2: Promoting ovulation and embryo transfer
The stage of promoting ovulation and embryo transfer in the process of IVF plays a key role in the success rate. Smoking will interfere with the hormonal balance in women and affect the effect of promoting excretion. A study from a famous reproductive center in China found that the success rate of smoking women in promoting ovulation was nearly 20% lower than non-smokers. At the stage of embryo transfer, smoking will increase the blood viscosity of endometrium and reduce the possibility of embryo implantation. A study by XX Hospital in Zurich, Switzerland, pointed out that the proportion of successful embryo transfer among smoking women was only half of non-smoking women. Therefore, smoking has a significant impact on the success rate of ovulation promotion and embryo transfer.
Aspect 3: Pregnancy complications
Smoking is closely related to pregnancy complications after successful IVF. Smoking women are more prone to spontaneous abortion, premature delivery and low birth weight of the fetus during pregnancy. A study by XX Hospital in Maryland, the United States, found that smoking and IVF increased the preterm birth rate by 50%, and the probability of low birth weight increased by 30%. Smoking in pregnant women can also cause fetal growth retardation and nervous system problems. Research from Cambridge University Hospital shows that smoking will affect the brain and nervous system development of the fetus, increasing the risk of complications during pregnancy. Therefore, smoking will not only affect the success rate of IVF, but also increase the possibility of complications during pregnancy.
Aspect 4: The influence of smoking cessation on the success rate of IVF
Fortunately, quitting smoking can improve the success rate of IVF. A study by XX Hospital in the UK found that the success rate of women who quit smoking during IVF was 30% higher than that of women who continued to smoke. Similarly, quitting smoking also has a positive impact on the quality of men's sperm, improving their fertility. Therefore, couples preparing for IVF should quit smoking as soon as possible to improve the success rate. Research shows that the fertility affected by smoking can gradually return to the normal level within 3 months to 1 year after quitting smoking.
summary
In conclusion, smoking has a significant negative impact on the success rate of IVF. Smoking will affect women's ovarian function and ovulation quality, interfere with ovulation promotion and embryo transfer process, and increase the risk of complications during pregnancy. However, quitting smoking can improve the success rate of IVF. Therefore, for couples who plan to have IVF, smoking cessation is a very important step, which can improve their chances of achieving their reproductive dreams.
