a million sperm and one egg--- it's amazing we get pregnant at all
Again, this above answer describes fertilization, not implantation. Once the egg is fertilized by the sperm (also called fusion of the gametes), its cells begin to divide. It is now a zygote.
Only about 1/3 of zygotes survive the journey through the fallopian tube to implant in the uterine wall (about a 10 day process). If it does, it is now an embryo.
Implantation
Implantation.
The implantation of the zygote occurs in the uterus. The developing fetus continues to grow and develop in the uterus until birth.
The term for a fertilized egg before implantation is a zygote. A zygote is formed when a sperm cell fertilizes an egg cell. It is a single cell with a complete set of chromosomes.
The journey of the zygote from the fallopian tube to the implantation site in the uterus typically takes around 5-7 days. This journey involves the zygote traveling through the fallopian tube and reaching the uterine cavity, where it eventually implants itself into the uterine lining.
zygote divides by mitosis as it travels along the oviduct to the uterus where implantation takes place. The zygote developes into embryo and placenta
The nutrients used by the zygote between fertilization and implantation come from the newly formed placenta. The placenta is what provides nourishment to the developing fetus.
This process is called implantation. During implantation, the blastocyst embeds itself into the lining of the uterus, where it will continue to develop into an embryo.
Implantation is the medical term meaning attachment of the zygote to the uterine wall. If the zygote does not attach, a period occurs.
A zygote travels from the oviduct to the uterus for implantation and further development into an embryo. This journey is facilitated by ciliary movement in the oviduct and uterine contractions.
Implantation occurs approximately 6 to 10 days after fertilization, when the fertilized egg, now called a blastocyst, attaches to the uterine lining. Following implantation, the zygote transitions into an embryo and begins to develop. This early stage is crucial for establishing the connection between the embryo and the mother's blood supply, enabling further growth and development.
The zygote develops into a blastocyst as it undergoes multiple divisions. This stage occurs before implantation in the uterus.
