Sperm that are easy to get pregnant are recommended to be abstinent for 5-7 days, and sperm that are ejaculated through intercourse have a greater chance of getting pregnant. Sperm have normal metabolic process, and sperm of 5-7 days have the best vitality and the highest number of effective sperm. If there is the process of ejaculation several times in a short period of time, many of the sperms emitted are infantile sperms. If the sperm ejaculated after too long abstinence, many of them are aging sperm remaining in the seminal vesicles, and the possibility of pregnancy in this case is to be reduced. If you plan to get pregnant, it is better to abstain from sex for 5-7 days and have intercourse during a woman’s ovulation period to be more likely to get pregnant.
