Day to day coitus sperm is definitely not good. Sperm have a period of production and maturation, the vast majority of sperm are produced in the testes and then gradually mature in the epididymis and are stored in the seminal vesicles. Sperm are ejaculated every time you have intercourse, so that many of the sperm ejaculated each time are just immature sperm. In this case, the sperm’s vigor, sperm’s survival rate are not particularly high, the possibility of pregnancy will not be too high. Therefore, it is not recommended to have intercourse every day. If you intend to get pregnant it is recommended that you should have regular intercourse, every 5-7 days, and have intercourse at the time of the woman’s ovulation. This way the sperm will have the best vigor and the success rate of pregnancy will be higher.
