the embryo attaches the mother
A few days after fertilization, the fertilized egg (now called a zygote) travels down the fallopian tube and implants itself in the lining of the uterus. Cells continue to divide and the zygote develops into a blastocyst, which will eventually form the embryo.
After fertilization, the fertilized egg, now called a zygote, undergoes several cell divisions to form a blastocyst. The blastocyst then implants into the wall of the uterus, where it begins to develop further. This process usually occurs around 6-10 days after fertilization.
Most experts agree that implantation happens between 10-14 days after conception.

Implantation typically occurs 6-12 days after fertilization. Once the embryo implants in the uterus, it can then develop and grow into a fetus.

basal stem cells.
The endometrium begins to form shortly after the fertilized egg (blastocyst) implants into the uterine wall (endometrium). This typically occurs 3-4 days after fertilization. After implantation, the endometrium is called the Decidua, and basalis is the portion directly under the blastocyst. The Basalis joins the chorionic villi to make the placenta. APEX~ a few days after fertilization
Fertilization can only occur during a specific window around ovulation, which typically happens approximately 14 days before the start of the next menstrual period. Sperm can survive in a woman's reproductive tract for up to five days, so if intercourse occurs in the days leading up to ovulation, fertilization is possible. However, outside of this fertile window, the chances of fertilization are significantly lower.
A few days after fertilization, the blastocyst forms as the fertilized egg undergoes several cell divisions and begins to develop. This structure will eventually implant into the uterine wall. At this stage, cells have not yet started differentiating significantly, and the development of the eyes occurs much later in the embryonic process. Therefore, the correct answer is B. The blastocyst forms.
No, sperm do not take three months to reach the egg. Once sperm are ejaculated, they can swim through the female reproductive tract and reach the egg within a few hours to a few days. However, sperm can survive in the female body for up to five days, allowing for a window of time for fertilization to occur after intercourse. The actual process of fertilization happens almost immediately once sperm encounters a viable egg.
