During the preparation period, not only women need to be prepared for pregnancy, but also men need to be prepared in all aspects, and there are more things to pay attention to. For example, it is necessary to quit smoking and drinking, do a good diet, strengthen physical exercise, and not to take drugs and x-ray examinations indiscriminately. It is best for men to quit smoking and alcohol during pregnancy preparation because the nicotine and alcohol in cigarettes have a great impact on male sperm quality, especially alcohol can cause an increase in male sperm malformation rate and lead to a higher possibility of chromosomal disorders in the fetus. In terms of diet, it is important to eat a light diet and eat more nutrients that are good for sperm production, such as oysters, kelp, shrimp, cuttlefish, sea cucumber, etc., because these foods have a high zinc content, and zinc is the main nutrient for male sperm production, and only with good sperm quality can you have a healthier baby. In addition, men who are preparing for pregnancy need to strengthen their physical exercise, such as running, basketball, fitness, etc. Only by enhancing their physical quality can they have stronger sperm. Try not to take drugs during the preparation period if you can do so, especially antibiotics, which contain certain ingredients that can kill or inhibit sperm, and try to reduce the number of X-rays and CT tests near the genital area. In addition to the above mentioned aspects, men also need to maintain a good state of mind during pregnancy preparation. Good emotions are also a key factor in having a healthy baby.
