There are many life details that need to be paid attention to during the preparation for pregnancy, such as diet, rest, and exercise. Some women still like to smoke, which must be quit. It is best to quit smoking and drinking. If it is the man who smokes, it is also best to quit because the harm of second-hand smoke is greater. Below, we will explain the impact of smoking on pregnancy.
1、 Does smoking affect pregnancy
1. During the preparation for pregnancy, it is best not to smoke. Second hand smoke can also have an impact, as smoking can affect ovarian function and induce or worsen gynecological inflammation. The prerequisite for pregnancy is the elimination of a fertilized egg. If ovarian function is disrupted or accompanied by other gynecological inflammations, then the prerequisite for pregnancy has been lost. It is recommended to quit smoking six months before preparing for pregnancy.
2. Male smokers experience a 10% decrease in normal sperm count. Individuals with a heavy smoking addiction who smoke 21 to 30 cigarettes per day have a significantly increased incidence of abnormal sperm; Those who smoke more than 30 cigarettes have a higher incidence of abnormal sperm. The longer the smoking time, the more abnormal sperm there are, and as the number of normal sperm continues to decrease, sperm motility will also weaken. Someone once analyzed over 5000 pregnant women and found that if their husbands smoke more than 10 cigarettes a day, the prenatal mortality rate of the fetus greatly increases; The more you smoke, the higher the infant mortality rate.
2、 The hazards of smoking during pregnancy
1. The incidence of premature infants is high. According to a survey of 7499 pregnant women, the incidence of premature infants in the smoking group was 12.5%, while in the non-smoking group it was 6.8%. The difference between the two was nearly double.
2. Smoking causes uterine contractions and increases the incidence of miscarriage.
3. The incidence of congenital malformations is high. According to a report, the incidence of congenital heart disease in infants was 0.77% in the smoking group and only 0.47% in the non-smoking group, with a significant difference.
4. Smokers with hypoxemia may experience early placental abruption, placental infarction, and an increased incidence of placenta previa in clinical practice.
The above is about the impact of smoking on pregnancy, especially the greater harm of second-hand smoke. Therefore, it is recommended that men quit smoking. Smoking also has an impact on the quality of sperm. Women who smoke during pregnancy mainly have an impact on the uterus and can cause miscarriage or even deformities.
