The human chorionic gonadotropin (hCG) is a hormone generated by the placenta during pregnancy. It thickens a person's uterine lining to support a developing embryo and instructs the body to cease menstruating. HCG levels rise after fertilization and continue to climb until approximately 10 weeks of pregnancy.
The human chorionic gonadotropin (hCG) is a hormone generated by the placenta during pregnancy. It's also known as the pregnancy hormone due to its specific role in pregnancy support. HCG is detected in your urine or blood 10 to 11 days after conception (when a sperm fertilizes an egg). Your hCG levels peak at the end of the first trimester (10 weeks of pregnancy), then fall for the remainder of your pregnancy. Healthcare providers use hCG to confirm a pregnancy and provide information about how the pregnancy is progressing.
After conception, a fertilized egg moves from your fallopian tubes to your uterus. The fertilized egg (known as an embryo) implants into the uterine wall. This causes the placenta to develop. Your placenta begins to produce and release hCG into your bloodstream and urine. HCG can be detected in a person's blood approximately 11 days after pregnancy. It takes slightly longer for hCG to appear on urine testing.
During the first eight to ten weeks of pregnancy, HCG levels rapidly rise (almost doubling every three days). Healthcare providers examine how quickly a person's hCG levels rise during early pregnancy to determine how the pregnancy and fetus are growing.
When your placenta starts producing hCG, it causes your body to produce more estrogen and progesterone. These hormones, along with hCG, help thicken your uterine lining and signal your body to cease menstruation (or producing eggs). The proper balance of these three hormones maintains and promotes the pregnancy.
A low or declining hCG level may mean several things:
If your hCG level is low for your gestational age, your doctor will repeat it in two or three days or perform an ultrasound to obtain a better look at your uterus.
High levels of hCG could indicate:
Abnormal growths on your uterus.
When used with IVF or IUI, HCG injections can boost your chances of getting pregnant. It works by causing ovulation (when the ovaries produce an egg).
If you have a history of infertility, monitoring hCG levels early in pregnancy can assist healthcare practitioners in determining whether a successful pregnancy occurred.
HCG aids in the creation of testosterone and sperm in people assigned male at birth (AMAB). It has also been used to treat undescended testicles in male babies.
When should I see my doctor?
Except when using an at-home pregnancy test, you are usually unaware of your hCG levels. Your healthcare professional may inform you that your hCG levels are low due to the gestational age of the pregnancy. Obstetricians often assess hCG early in pregnancy but do not continue to do so until there are indicators of difficulties. If your healthcare practitioner is worried about the course of your pregnancy, they will recheck hCG levels and perform other diagnostic testing such as an ultrasound.
