hCG, the wonder of today's science

hCG is a wonder of today's science. It firstly is extreme molecule, including features such as the most acidic molecule, the most glycosylated molecule and the longest circulating half life. It secondly is unique with multiple variants of hCG having independent functions, and hCG variants binding 2 separate receptors, hLG/LH receptor and TGFß receptor. hCG needs to be considered as a placental hormone and autocrine, a pituitary hormone and a major cancer promoter.

 The Mysteries Of HCG & It’s Many Uses

Both men and women have small amounts of Human Chorionic Gonadotropin, or hCG, in their body at all times, although it’s more well known for its maternal recognition of pregnancy. The trophoblast cells that surround a growing embryo produce it, so naturally, pregnancy tests were developed to detect it’s presence… Two lines and you’re pregnant! (if you’re a biological female).

 Understanding Human Chorionic Gonadotropin: The Hormone of Life

Human chorionic gonadotropin (hCG) is a fascinating hormone that plays a pivotal role in pregnancy and fertility. Produced by the placenta shortly after implantation, hCG signals the body to maintain the production of progesterone, which is crucial for sustaining pregnancy. But what does this mean beyond its biological function? For many, hCG is synonymous with early pregnancy tests. When you see those two pink lines appear on a test strip, it’s hCG that has triggered that joyful moment. This hormone can be detected in urine or blood just days after conception, making it an essential marker for confirming pregnancy.

Human Chorionic Gonadotropin: The Pregnancy Hormone and More

Human chorionic gonadotropin (hCG), also known as “the hormone of pregnancy” has an important role in human reproduction. Several studies have demonstrated its crucial part in establishing and maintaining pregnancy, through placentation and early embryo development. In addition to that, hCG has been used in assisted reproduction protocols by mimicking the endogenous Luteinizing Hormone (LH)-surge during late follicular phase to induce final follicle and oocyte maturation and ovulation. Recent data suggest a participation of regular hCG and its variant, hyperglycosylated hCG in hemochorial placentation, which is important for the development of the advanced human brain. Moreover

The Skinny on HCG: Weight Loss Wonder or Legal Blunder?

In the ever-evolving world of weight loss trends, one name has managed to stay in the limelight despite controversy and legal battles: HCG. This hormone-based diet has sparked debate among health professionals and consumers alike.

Common Myths About hCG

hCG is a supplement that is used to losing weight and gaining muscle mass. As with many non-traditional supplements, hCG is a topic that is surrounding by a misunderstanding about what it does and how well it works. Here are some of the most popular myths about hCG.

Everything You Need To Know About HCG

The primary role of hCG is to support pregnancy by triggering the release of hormones, particularly progesterone. HCG is made in the cells of the corpus luteum—remnants of the ovarian follicle that produce the fertilized egg. The corpus luteum makes the hormones needed to maintain pregnancy until the placenta has fully formed. Until then, your hCG levels rise quickly, doubling and eventually peaking around 10 weeks of pregnancy. Once the placenta maintains your hormone levels, your hCG levels drop to a fixed level.

hCG: Biological Functions and Clinical Applications

The hCG molecule is an extremely important multifaceted hormone involved in hormonal interactions of the fetal-placental-maternal unit, as well as neuroendocrine and metabolic changes that occur in the mother and in the fetus during pregnancy and at parturition, as well as pathophysiologic functions in non-pregnant women...

New discoveries on the biology and detection of human chorionic gonadotropin

Placental hCG replaces pituitary LH in controlling progesterone production at the initiation of pregnancy, from implantation of pregnancy (~3 weeks gestation) to 6 weeks of gestation.

The Beta hCG hormone: everything you need to know about the pregnancy hormone

Beta hCG (human chorionic gonadotropin) is the famous hormone that can detect pregnancy ! Produced by the cells of the placenta ( trophoblastic cells) 6 days after conception (at the time of implantation), beta HCG serves to support the corpus luteum (ovarian secretions) to prevent the return of menstruation and stimulate the production of progesterone: essential to ensure the normal development of a pregnancy.

The beta hCG test is commonly used to confirm pregnancy. Learn how to interpret the results of this test.

The bottom line is that beta hCG testing is just one data point we use to confirm a pregnancy. While a positive result generally indicates pregnancy, the level of hCG alone is not sufficient to determine the viability of the pregnancy or potential complications.

The Comprehensive Guide to Human Chorionic Gonadotropin (hCG)

The production of hCG commences soon after the embryo embeds itself in the uterus, with its levels typically doubling every 48 to 72 hours during the initial phase of a healthy pregnancy. While hCG levels can fluctuate, they are generally found to be between 5 to 50 mIU/mL in the early stages of pregnancy. These levels tend to rise, reaching their peak between the 8th and 11th weeks, before settling to a consistent level for the remainder of the pregnancy.

What is HCG? Role of the Pregnancy Hormone Explained

HCG (Human Chorionic Gonadotropin) is known as the pregnancy hormone because it is produced by cells in the placenta and nourishes the egg after it has been fertilised and adheres to the uterine wall. A blood test can identify levels 11 days after conception, followed by a urine test 12-14 days later.

What Your HCG Levels Might Mean During Pregnancy

Initially, hCG is secreted to help maintain the corpus luteum—a collection of cells that make the uterus a healthy place for pregnancy—adds Julie Lamppa, APRN, a certified nurse-midwife at the Mayo Clinic. Eventually, your placenta—the organ that provides oxygen and nutrients to your growing baby—will take over progesterone production and hCG levels will dip.

Your hCG Levels by Week—and What They Might Mean

It’s important to know that levels of hCG typically only increase until a certain point in your pregnancy. According to experts, hCG will peak sometime between weeks 8 and 12, before starting to decrease. But why do hCG levels begin to fall during this time? It’s because your placenta has developed enough to take over and can start supplying progesterone to your pregnancy to help it progress, Lamppa explains.

100 Years of Human Chorionic Gonadotropin

The hCG immunoassay, in one form or another, is now one of the most common medical tests conducted and is often the first indication that a mother-to-be is pregnant. Not only a marker of pregnancy, hCG is utilized in the diagnosis and monitoring in oncology and presents a potential target for novel cancer therapeutics.

StatPearls

Human chorionic gonadotropin (hCG) is a chemical created by trophoblast tissue, tissue typically found in early embryos and which will eventually be part of the placenta. Measuring hCG levels can be helpful in identifying a normal pregnancy, pathologic pregnancy, and can also be useful following an aborted pregnancy. There is also a benefit in measuring hCG in a variety of cancers including choriocarcinoma and extra-uterine malignancies.
