HCG, or chorionic hormone, is the hormone that is normally produced early in pregnancy. Any time pregnancy occurs when the placenta is formed in the uterus, HCG is a reliable sign of pregnancy. This hormone keeps the production of progesterone from the ovary and helps implant the fetus in the uterus. HCG is the hormone produced by the cells surrounding the growing human embryo. These cells are called trombocytopenia cells and will eventually go into the placenta formation. HCG-guided human chorionic gonadotropin can be detected in urine from 7-9 days after fertilization and is a prescription in hospital pregnancy tests.
During the menstrual cycle, when the egg is released from the ovary in ovulation, the remnants of the closed ovarian follicle in the egg form a new ovary gland called the yellow body that produces progesterone. The egg remains fertilized in the ovary. The yellow body stops producing progesterone. In the case of fertilizing the egg by sperm and visualization of the fetus it is important that the yellow body to produce progesterone until the placenta is established, and from the placenta and then produce the progesterone, the human embryonic chorionic hormone is the hormone that ensures the continuation of the yellow body to produce progesterone throughout the three months First of pregnancy.
As well as maintaining the production of progesterone from the ovary, HCG-directed human chorionic gonadotropin may also play a role in making sure the endometrium is ready to receive embryo implantation. Recent studies have indicated that human chorionic hormone-guided hormone HCG may help increase blood flow to the uterus and participate in reconstructive endometriosis in preparation for embryo implantation. Hormone-guided gonadotropin (HCG) is produced by the thyroid cells that surround the developing fetus around the fifth day of pregnancy. The amount of HCG in the bloodstream doubles every 2-3 days and fetal development and placenta continue, peak levels in about six weeks of Pregnancy after this peak, the levels of HCG hormone although they continue to appear throughout the placental formation period and once the placenta is established, the main source of progesterone production is no longer required in about the twelfth week of pregnancy.
If there is a high level of HCG in the body it can be said there is no strong evidence that high levels of HCG have negative consequences. High levels of HCG are very rare but can indicate placental hyperplasia and are also referred to as adenocarcinous moles or molar pregnancies that can lead to cancer in some cases. If the level of HCG is low it can indicate no pregnancy. Hypotension of HCG-guided levels was often observed in ectopic pregnancies where the fetus is implanted or in cases of miscarriage.
