40 Facts About Human Chorionic Gonadotropin (hCG)

What is Human Chorionic Gonadotropin (hCG)?

Human Chorionic Gonadotropin, commonly known as hCG, is a hormone produced during pregnancy. It plays a crucial role in maintaining the pregnancy and supporting fetal development. Here are some fascinating facts about hCG.

1. hCG is produced by the placenta: The placenta, which nourishes the fetus, starts producing hCG shortly after the embryo attaches to the uterine lining.

2. hCG levels rise rapidly in early pregnancy: During the first trimester, hCG levels double approximately every 48 to 72 hours.

3. hCG is used in pregnancy tests: Home pregnancy tests detect the presence of hCG in urine to determine if a woman is pregnant.

4. hCG supports the corpus luteum: This hormone helps maintain the corpus luteum, which produces progesterone necessary for sustaining the early stages of pregnancy.

5. hCG levels peak around 10 weeks: After peaking, hCG levels gradually decline and stabilize for the remainder of the pregnancy.

Medical Uses of hCG

Beyond its role in pregnancy, hCG has several medical applications. It is used in various treatments and diagnostic procedures.

6. hCG is used in fertility treatments: It can trigger ovulation in women undergoing fertility treatments like in vitro fertilization (IVF).

7. hCG can treat male hypogonadism: This hormone stimulates testosterone production in men with low testosterone levels.

8. hCG is used in weight loss programs: Some weight loss programs use hCG injections, although this practice is controversial and not widely endorsed by medical professionals.

9. hCG can diagnose certain cancers: Elevated hCG levels can indicate the presence of certain cancers, such as testicular cancer and choriocarcinoma.

10. hCG is used in prenatal screening: It helps assess the risk of chromosomal abnormalities like Down syndrome during pregnancy.

How hCG Affects the Body

The presence of hCG in the body triggers various physiological changes, especially during pregnancy.

11. hCG causes morning sickness: High levels of hCG are linked to nausea and vomiting in early pregnancy, commonly known as morning sickness.

12. hCG supports fetal development: It ensures the fetus receives adequate nutrients by promoting the growth of blood vessels in the uterus.

13. hCG affects the immune system: This hormone helps modulate the mother's immune response to prevent the rejection of the fetus.

14. hCG influences the thyroid gland: It can stimulate the thyroid, leading to increased production of thyroid hormones during pregnancy.

15. hCG can cause mood swings: Hormonal changes, including fluctuations in hCG levels, can contribute to mood swings in pregnant women.
