Failure Early pregancy : Blighted ovum , Anembryonic pregancy

 

·        What is the natural pregancy loss in healthy fertile young women??  Ans & Reasons:-Once the embryo reaches the blastocyst stage, approximately five to six days after fertilization, it hatches out of its zona pellucida and begins the process of implantation in the uterus. In nature, 50 percent of all fertilized eggs are lost before a woman's missed menses. Q,2:What is Chemical pregnancy ? Ans;– This is a very early miscarriage. It usually happens in the first few weeks after conception. Chromosomal abnormalities keep the embryo from developing normally. The menstrual tissue that is passed from uterus around the same time that normally have her period also contain the degenerated blastocyst. Most , if not all such  women don’t even know they are pregnant when they have a miscarriage from a chemical pregnancy, but beta hCG in serum will be positive on day 23-35 of that fertile cycle .

·        Q.3: Blighted ovum – This is termed when y Sac don’t develop but sac imagable and > 8 mm.

·        Q.4: What is  an embryonic pregnancy. It happens when the fertilized egg implants in the wall of the uterus, but a fetus never develops. GSD will be there with normal sac growth but though the Y sac will be visible but no embryonic pole will be visible even  after follow up scan after say 7-10  days .

·        Q,6 :Ectopic pregnancy – This is when the fertilized egg implants somewhere other than the uterus. Often, it implants in the fallopian tube. This can cause serious problems for the mother. Treatment — usually surgery — is needed right away to remove the tissue.

·        Molar pregnancy – This is a rare problem that starts with a genetic error during fertilization. This causes abnormal tissue to grow instead of an embryo. It is not a viable pregnancy. But it still causes regular pregnancy symptoms. These include a missed period, positive pregnancy test, and nausea.

·        Causes of such five conditions ? These are failure of fertilized zygote to grow and develop normally. Quite often, these are random problem with A) chromosomes that happens at conception. B) Problems with the immune system C) Thyroid disease

·        d) Polycystic ovary syndrome.
