What happens to my embryos if they do not implant ?



Scanning electron microscopy (SEM) of a human blastocyst that adhered to the endometrium (during cell culture). The blastocyst is oblong and flattened, presenting many short microvilli at the apical surface. Many trophoblastic cells have bulging surfaces, thereby illustrating cell borders. The blastocyst adhered to a pinopode presenting area on the endometrial cells. Flattened endometrial cells dominate the surrounding area with microvilli at the apical surface. Single ciliated cells are interspersed (scale bar = 130 μm).   © European Society of Human Reproduction and Embryology
 
If my embryos do not implant , what happens to them ?
The embryo(s) which are transferred to your uterus are just microscopic ball of cells. You cannot see your embryo with your naked eye; you need a microscope , which would enlarge it several hundred times , before you can view it. When your embryos fail to implant and give rise to a pregnancy, they die and disintegrate. Cells die in the human body all the time, and these dead cells are removed by your body’s scavenging machinery. When you get periods after a failed cycle, only the endometrium which is formed during that particular IVF cycle is sloughed off. Since you took lots of hormones , your endometrial lining might be thicker than usual and you might experience heavier menstrual bleeding or you might have more clots (which appears like a tissue) than you normally do. This doesn’t mean you are having a miscarriage or that the transferred embryo was expelled.
If one of my embryos implant, what happens to the other embryo(s) which was transferred along with it?
The embryos which did not implant die and disintegrate. They are removed by your bodies cleaning machinery. You do not need a menstrual period to remove them from your uterus and neither do they harm your developing baby, so do not panic !

  2. I am a hypogonadotropic hypogonadism case also, and I am on my 8th day post FET today! Can you tell me if you had success with your cycle? This is my 1st FET, after 2 failed fresh cycles.
