Sperm quality for 3 consecutive days of intercourse may affect pregnancy. Sperm quality is related to the sperm formation cycle. Under normal circumstances, it takes about 3 months for a man’s sperm to mature from generation to maturity, and studies have confirmed that after a single ejaculation, it usually takes 48-64 hours for sperm to fill the epididymal ducts from the testicles. Therefore, having intercourse for 3 consecutive days will lead to a gradual decrease in sperm quality. If there is a plan to prepare for pregnancy, you can have intercourse every other day before and after a woman’s ovulation, which can improve the chances of pregnancy and will not affect the quality of sperm. Men can usually exercise more exercise, develop good habits. At the same time, the sex life should be regular, avoid too frequent, and reduce the number of masturbation, so as not to affect the quality of the sperm.
