Occasional alcohol consumption by men does not have much effect on conception, but if they drink frequently, it will have an effect on conception, and the effect is more significant.
Generally, it is recommended that both men and women should quit smoking and drinking during the first 3 months of pregnancy, because the alcohol content in wine will affect the reproductive system and physical health when it enters the body, which is not conducive to eugenics.
If a man is an occasional drinker, the effect on sperms is not significant and will not cause any major harm or impact on conception. However, if a man is a frequent drinker and heavy drinker, a large amount of alcohol will affect the quality of sperms, leading to a decrease in the number or vigor of sperms, which will affect the chances of conception, and may even increase the incidence of fetal malformations when getting pregnant after drinking alcohol.
It is recommended that men do not drink alcohol during the preparation period, and delay pregnancy appropriately after drinking, it is best to quit drinking for three months before getting pregnant, in order to facilitate eugenics.
