I believe many people have doubts about how long it takes for sperm to enter a woman's body to become pregnant. Understanding this question is important for couples who want to conceive a baby. If couples want to successfully conceive a baby, the key is to correctly grasp the conception time. So, how long does it take for male sperm to enter a woman's body to become pregnant?
Generally, it takes 4-5 days for male sperm to enter the female body and become pregnant. Sperm can survive for about 72 hours after entering the vagina, while sperm exposed to the outside can survive for less than 2 minutes. After the egg is released from the ovary, it takes about 8-10 minutes to enter the fallopian tube, pass through the fimbriae of the fallopian tube to reach the junction of the fallopian tube and isthmus (ampulla of the fallopian tube), and stay in the ampulla. If encountering sperm, fertilization occurs here.
The site where human egg cells and sperm combine is mostly in the ampulla of the fallopian tube. Groups of sperm undergo contractions of the uterus and fallopian tube muscles during their movement, causing a large number of sperm to lose vitality and decay. Eventually, only about 20-200 sperm reach the periphery of the egg cell, and only one sperm can combine with one egg. The fertilization process takes about 24 hours. When an empowered sperm enters the zona pellucida of a secondary oocyte, the fertilization process begins. When the chromosomes of the egg nucleus and sperm nucleus fuse together, it marks the completion of the fertilization process.
