What happens when embryo implants in fallopian tube?
An ectopic pregnancy occurs when a fertilized egg implants and grows outside the main cavity of the uterus. An ectopic pregnancy most often occurs in a fallopian tube, which carries eggs from the ovaries to the uterus. This type of ectopic pregnancy is called a tubal pregnancy.
How long can an embryo survive in the fallopian tube?
The fetus rarely survives longer than a few weeks because tissues outside the uterus do not provide the necessary blood supply and structural support to promote placental growth and circulation to the developing fetus. If it’s not diagnosed in time, generally between 6 and 16 weeks, the fallopian tube will rupture.
Which side of the uterus does the embryo implant?
The fundus is located at the top of the uterus and is connected to the fallopian tubes. The body of the uterus begins below the opening for the fallopian tubes. This is generally where the fetus will implant and this portion of the uterus stretches to accommodate the developing baby.
What are the signs of fallopian tube blockage?
A blocked fallopian tube may cause some women to experience symptoms such as pain in the pelvis or belly. This pain might happen regularly, such as around the time of their period, or be constant. Sometimes, a blockage in a fallopian tube can cause a fertilized egg to get stuck. This is known as an ectopic pregnancy.
What happens after blastocyst transfer?
After an Embryo Transfer Day 1: The blastocyst begins to hatch out of its shell. Day 2: The blastocyst continues to hatch out of its shell and begins to attach itself to the uterus. Day 3: The blastocyst attaches deeper into the uterine lining, beginning implantation. Day 4: Implantation continues.
What happens if blastocyst does not implant?
If implantation does not occur, the endometrium breaks down and sheds, along with the blastocyst, as part of the menstrual cycle. However, if a blastocyst does implant, then the endometrium remains in the uterus, and together with uterine tissue, becomes the maternal portion of the placenta, called the deciduas.
