Pregnancy occurs when a sperm fertilizes an egg. If sperm is deposited inside the vagina during intercourse, it can potentially make its way to the egg in the fallopian tube and lead to fertilization and pregnancy.
Conception is the beginning of pregnancy in that it is the joining of the sperm and egg. During implantation, the fertilized egg embeds in the uterine wall.
If sperm does not enter the vagina, there is no chance of pregnancy. Pregnancy occurs when sperm fertilizes an egg, and this can only happen if the sperm comes into contact with the vagina and eventually reaches the egg in the fallopian tubes. Without this contact, pregnancy cannot occur.
An embryo forms first during pregnancy, after fertilization of the egg by sperm. It develops into a fetus around the end of the eighth week of pregnancy.
