7 days from fertilization.
Implantation of an embryo typically occurs around 6-10 days after fertilization. Embryos should be at the blastocyst stage when they implant, which is around day 5-6 after fertilization.
I am not sure but my biology teacher said it took 6-7 days
In many countries, destroying embryos after 14 days is a regulatory limit imposed to prevent ethical concerns related to the development of human life. It is believed that 14 days is the point at which the embryo begins to develop its primitive streak, which some consider a marker of individuality or the beginning of a sentient being.
The process of creating an embryo can take around 24 to 48 hours. This includes the fertilization of the egg by the sperm, initial cell division, and the formation of the embryo.
The embryo develops over the course of 9 months in the womb before it is born as a baby.
I have heard that there was the first uterus implant done in another country, and subsequently heard that they were studying implanting uteri in the U.S. The U.S. has not perfected a method of a permanent uterus implant, however. The method they are studying now includes anti-rejection drugs so that the woman the uterus is implanted to can have the uterus implant until after she gives birth, then it is removed. I am hopeful that they will continue this study, but I have heard that many people find a uterus implantation ethically "wrong", fearing that men will ask for this implant.

When a cell mass is fully implanted in the uterus, it is called a blastocyst. This is a stage of embryonic development where the fertilized egg has divided into many cells and is ready to implant into the uterine lining for further growth and development.

Zygote vs Embryo- A zygote is the formation from the two gametes, the sex cells sperm and egg. (pronuclei). It forms in about 3 days.- An embryo has 3 main structural parts, further developed (forms in the 2nd week after pregnancy).1. Brain/spinal cord, skin, nerves2. Digestive system organs3. Heart, muscles, & skeletal systemThey both exist in the womb (uterus).This website was helpful for me understanding pregnancy: http://i.ivillage.com/first9months/babypp.swfby username: xDGoMuSiCxD (Naomi) :) I hope this helped.
Sperm have about three days to make it to the egg for fertilization before the egg passes out of the uterus and dies.
The gestation period (pregnancy) for a cheetah is about 90 to 98 days.
Uh. What the heck. You not know 'bout that? Duurr. Urgh. :"<

Approximately 25-30% of zygotes become successfully implanted in the uterus. Many factors can affect successful implantation, such as the health of the embryo and the receptivity of the uterine lining.
