How does pregnancy occur?

In each ejaculation, a man ejaculates a semen containing millions of sperms, and the semen can be described as a white, sticky fluid. Vagina, as a result of having sex without a condom or barrier, sperm travel from the vagina to the cervix, then to the fallopian tubes through the uterus (Uterus).

When the sperm meets the egg, it produces a fertilized egg, or what is known as the zygote, and this process is known as fertilization, then the fertilized egg begins to divide during its travel through the fallopian tube to form what is known as a blastocyst. days, then this blastocyst moves to the uterus to be implanted in it during a process known as implantation, and at this precise moment it can be said that the woman is pregnant, and medical means can detect the occurrence of pregnancy at this time, and as the blastocyst continues to mature, it becomes an embryo. Embryo, and after a few weeks the embryo grows into an embryo. It is worth noting that pregnancy may occur through artificial insemination (in English: In Vitro Fertilization); Where the egg is fertilized with sperm outside the woman’s body, then the doctor transfers the fertilized egg to the woman’s body to begin the process of pregnancy.[١]
