The day after intercourse the day before ovulation the effluent may be semen and a small amount of sperm, most of which has already entered the female reproductive tract.
Male semen begins to liquefy when it enters the female vagina, and when he wakes up the next morning, the liquefied semen will be discharged from the vagina due to the change in body position, which still contains a very small amount of sperm, which is a normal phenomenon.
When the semen enters the vagina, the sperm will quickly enter the female reproductive tract, and if the woman happens to ovulate at this time, it is possible that it will meet and combine with the egg to form a fertilized egg.
If a man has problems with the quality of his sperm, such as weak motility or a high number of deformed sperm, it may affect the sperm’s vitality and its ability to enter the female reproductive tract, leading to infertility.
