Does IVF have a big impact after smoking?
With the progress of science and technology, IVF technology is becoming more and more mature, providing a hope for couples who cannot conceive naturally. However, whether the mother smoking in the IVF test will affect the fetus has become a topic of great concern. In this article, we will discuss the influence of IVF smoking on the fetus from several aspects.
Impact 1: birth defects
Smoking plays a crucial role in the incidence of birth defects in test tube infants. According to research, smoking by mothers during IVF pregnancy increases the risk of fetal birth defects. Many well-known hospitals in the world, such as Children's Hospital affiliated to Harvard Medical School in the United States and Children's Hospital in London in the United Kingdom, have conducted relevant research. They found that if the mother of a test tube baby smoked during pregnancy, the fetus was more likely to suffer from heart disease, cleft lip and neural tube defects.
In addition, smoking can also reduce the birth weight of IVF babies and increase the risk of premature delivery. These defects may have long-term effects on the life and health of infants. Therefore, it is suggested that the parents of IVF should try not to smoke during pregnancy to reduce the risk of birth defects.
Impact 2: Reproductive issues
IVF smoking may have a negative impact on the reproductive system. Studies have shown that harmful chemicals in tobacco can interfere with the normal secretion of estrogen and progesterone. This can lead to dysfunction of the female reproductive system, such as decreased ovarian function and insufficient progesterone secretion.
In addition, IVF smoking may also affect male fertility. Smoking can lead to a decline in semen quality, including a decrease in sperm count and motility. This will increase the difficulty of pregnant healthy embryos and may lead to an increase in the failure rate of IVF.
Impact 3: Immune system
After the embryo of IVF is transferred to the mother, it needs adequate nutrition and protection in the mother. However, IVF smoking will weaken the function of the mother's immune system, thus making the embryo more vulnerable to infection.
In addition, IVF smoking can also cause the embryo to fail to take root normally in the uterus. Studies have found that smoking can lead to insufficient blood supply to the endometrium and affect embryo implantation and growth. This may lead to IVF implantation failure or spontaneous abortion.
Impact 4: Gene mutation
In vitro infant smoking may increase the risk of embryonic gene mutation. Studies have shown that maternal smoking can cause abnormalities in the genetic material of embryos, including gene mutations and chromosomal abnormalities. These abnormalities may lead to abnormal embryonic development, which may affect the health of infants.
In general, IVF smoking will have a serious impact on the fetus. Smoking will increase the risk of birth defects, affect the normal function of the reproductive system, weaken the immune system and increase the probability of gene mutation. Therefore, for parents of test tube babies, smoking cessation is a very important measure to ensure the healthy growth of the baby.
