Normally, intercourse during ovulation can lead to pregnancy.
Pregnancy is a relatively normal physiological phenomenon and a basic way of human reproduction. If contraception is not used during sex, the combination of sperm and egg can lead to pregnancy.
When a mature sperm meets an egg, the sperm undergoes an acrosome reaction in the vagina, penetrates the egg’s zona pellucida and enters the oocyte, fusing the egg prokaryotic nucleus with the sperm prokaryotic nucleus to form a fertilized egg. The fertilized egg will develop into an embryo, which will divide in the uterine cavity and then continue to divide into a blastocyst. Finally it is implanted in the uterine cavity and then pregnancy occurs.
A woman of childbearing age releases an egg every month. As the egg matures in the ovary, it is expelled from the ovary and transported through the fallopian tube to the uterus. Generally, the egg is fertilized only 24-36 hours after ovulation, while the sperm survives in the uterus for 24-72 hours. If you have intercourse during ovulation, the likelihood of pregnancy is high.
Pregnancy is a normal physiological phenomenon that can result from coitus without contraception as long as the woman and man of childbearing age are in good health. If you do not wish to have children in the near future, it is recommended that you use contraception.
