After the egg drops from the ovary, it travels through the Fallopian tube, where there's about a 24-hour window when it can be fertilized. Even if you try to summit Everest, this is the most dangerous journey you will ever take. If all goes right, the sperm meets the egg in the Fallopian tube and the two half-genomes unite to form a complete set of genes containing all of the DNA necessary to make a new human being.
The fertilized egg says thank you very much and moves along to the uterus. There, it will attach to the uterine lining and begin the amazing process of becoming a baby. Once the sperm fertilizes the egg, the fragile blastocyst multiplies its cells and must implant on the uterus wall to endure the 280-day pregnancy.
