HCG Role In Pregnancy

Human chorionic Gonadotropin (HCG) can be explained as a hormone that is produced by embryonic cells during implantation of the embryo on the uterine wall. It mainly maintains the corpus luteum at the start of the pregnancy.

The corpus luteum secretes progesterone and small amounts of estrogen. These hormones, especially progesterone cause the endometrial glands to secrete and prepare the uterus wall for the implantation of the embryo. Progesterone helps to enrich the uterus with blood vessels and capillaries. Beta HCG therefore plays a very important role in sustaining and maintaining pregnancy.

It aids in the development of cells in the walls of the blastocyst in the developing embryo. These cells help in the implantation of a newly fertilized egg in the uterus. Furthermore, it also signals the uterine wall about the impending implantation. It also suppresses uterine muscle contractions in the duration of the pregnancy.

Since it is produced during the second week of embryonic development, HCG forms the basis of pregnancy tests. Positive readings of high levels of the hormone in the blood or urine of a woman may indicate pregnancy. The maintenance of the corpus luteum prevents the onset of menstrual periods.

 

HCG causes the blocking of immune action (Immunosuppression) by the mother’s cells or foreign placental cells. This protects the fetus during the first trimester. It promotes blood supply and circulation in the uterus wall to support the developing placenta. Placental vascular development is crucial to fetal growth and development. This prevents early pregnancies and pregnancy related conditions.

It facilitates growth and differentiation of the umbilical cord and promotes development of the fetus in line with the uterus. HCG plays a part in the growth of the fetal organs during the pregnancy. It produces the similar effects of luteinizing hormone (LH). These effects are stimulation of the production of testosterone in the testes of a male fetus and development of the male genital system.

Another function of HCG is in the medical field to clinically induce ovulation in the ovaries. This is invaluable to treatment of fertility problems. Additionally, it boosts testosterone production in the testes, thus used to boost sperm count. A condition in young boys where the testicles haven’t dropped into the scrotal sac is also treated using HCG. It is extracted from the urine of pregnant women or genetically cultured in a lab. It is extensively employed in in vitro fertilization procedures.

Recently human chorionic Gonadotropin is being used to encourage weight loss. This technique involves pills, role of hcg injections in early pregnancy and oral drops. The HCG’s role is to lower the user’s appetite and is prescribed with a low calorie diet. This diet plan however, has been subject to controversies. This is largely because of lack of extensive medical research on its suitability.

The HCG diet plan actually does help someone lose weight. However, there is no scientific consensus that it is indeed the hormone that causes the reduced appetite. Many doctors have attributed the weight loss to the low calories. This plan poses the risk of some women developing multiple pregnancies. Overall this article gives a outline of role played by the HCG in early and during pregnancy.
