When Does Implantation Take Place in Normal Pregnancies?
- Sperm can travel through the vagina, past the cervix, and up to the Fallopian tubes when you have unprotected sex. Here, a sperm and an egg are most likely to mate.
- Fertilization occurs when the sperm and egg join forces.
- After then, the fertilized egg ascends to the uterus for implantation. Its cells divide and procreate while simultaneously expanding in size.
- This fertilized egg begins to prepare for implantation once it locates the ideal location to adhere to the uterine wall.
- The pregnancy begins when the fertilized egg implants itself to the uterine lining. When implantation takes place in the uterus, about 30% of women suffer very minor bleeding.
- After having sex, the embryo usually implants in the uterus 7 to 14 days later.
When Does Implantation Take Place in IVF?
The fertilized eggs or human blastocysts used in in vitro fertilization (IVF) typically break through their shells and begin to implant one or two days following the fifth day of the transfer of the IVF blastocysts. This indicates that the implantation happens 7 to 8 days after the egg is fertilized. In both natural and IVF-assisted pregnancies, the period needed for implantation is essentially the same.
