No, ejaculating once cannot cause pregnancy.
Pregnancy occurs when a sperm cell fertilizes an egg. While ejaculation releases sperm, it does not guarantee fertilization. For pregnancy to happen, several factors need to align:
-
Sperm must reach the egg: This requires the sperm to travel through the vagina, cervix, uterus, and fallopian tubes.
-
The egg must be present and receptive: A woman ovulates, releasing an egg, only once a month. The egg is viable for fertilization for about 12 to 24 hours.
-
Fertilization must occur: The sperm must successfully penetrate the egg's outer layer.
Therefore, even if a man ejaculates inside a woman, pregnancy is not guaranteed.
If you have any questions about pregnancy or contraception, it's always best to consult with a healthcare professional.
