HCG Hormone

The hormone HCG The hormone HCG or beta-HCG (English Human Chorionic Gonadotropin) is a hormone secreted during pregnancy. She has a particular role, and dosage can reveal a multitude of elements, in connection with pregnancy or not.

What is HCG and what is its role?

 The hormone HCG is secreted at the time of implantation, ie when the embryo attaches to the uterine wall, for what would become the placenta.Son role is to maintain the corpus luteum, which is a small formation inside the egg, whose role is to secrete progesterone itself necessary for implantation. Clearly, for the egg is fixed and that the embryo develops, the body needs progesterone, which requires the corpus luteum, itself dependent on the hormone HCG. Its role in pregnancy is therefore essential.

The hormone HCG: a powerful indicator

 This is first HCG hormone that detects pregnancy as it is present in the blood about ten days after fertilization, and in the urine a few days later. It is precisely that it blood and urine tests looking for.

 It then allows to know the exact date of pregnancy by assaying the rate because it varies very precisely during the grossesse.Son assay allows also to ensure the smooth running of pregnancy, because if there is a miscarriage or an ectopic pregnancy, the HCG hormone levels raised the alarm.

Finally, through a mix between the 15th and 17th weeks, the HCG is even a risk indicator trismomie 21! If the rate indicates a risk, amniocentesis may be required to confirm the anomaly, or not.
