Implantation
Implantation is the medical term meaning attachment of the zygote to the uterine wall. If the zygote does not attach, a period occurs.
Implantation.
Identical twins or triplets.
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.
If a zygote attaches to the wall of the fallopian tube it is called an ectopic pregnancy. If it continues to grow, it will cause the tube to rupture and the mother to hemorrhage. If left untreated this can lead to death. Ectopic pregnancies have to be terminated because they are never viable and can be life threatening to the mother.
A fertilized egg is a zygote for the first five days before becoming a blastocyst. It is during the first week after insemination that the zygote will attach to the uterine wall.
The process that the zygote undergoes to grow is called cleavage. During cleavage, the zygote divides repeatedly through mitotic cell divisions, leading to the formation of a multicellular structure known as a blastocyst. This stage eventually implants into the uterine wall, where further development occurs.
Scar tissue and damage from infections (which often creates micro scarring) These typically arise from either multiple miscarriages (which can cause internal scratches which scar over) or improperly treated STD's. which lead to infections (and damage to the uterine wall). Scarring whether large or in micro tears creates toughened wall linings which make it difficult to impossible for the process to begin as the zygote will not be able to form attachment to the uterine wall. Without that attachment every attempt at pregnancy is just flushed from the system in its earliest gestation period.
The term for the surgical attachment of the uterus to the abdominal wall is "hysteropexy." This procedure is typically performed to stabilize the uterus in cases of uterine prolapse. By securing the uterus to the abdominal wall, it helps restore its normal position and function.
It thickens with tissue and nutrients to prepare to sustain a fertilized egg. This is what is shed during menses and what is seen, as the egg is virtually undetectable by itself.
Fertilized ovum implants itself on the wall of the uterus. It is called as zygote.
Uterine fibroids refer to benign tumors that start in the uterus. They are the same smooth muscle fibers as the uterine wall but they are denser than normal uterine wall.
