Beta-hCG (Ξ²-hCG) β short for beta-human chorionic gonadotropin β is a hormone produced during pregnancy. It plays a crucial role in supporting the pregnancy, especially in the early stages.
𧬠What is Beta-hCG?
It's made by cells of the placenta shortly after a fertilized egg attaches to the uterus.
It's the hormone detected by pregnancy tests β both urine and blood tests.
πΌ Role in Pregnancy:
Maintains the corpus luteum in the ovary, which keeps producing progesterone in early pregnancy.
Helps maintain the uterine lining for embryo implantation and growth.
Stimulates development of fetal organs and the placenta.
π Beta-hCG Levels in Early Pregnancy:
In a healthy early pregnancy, Ξ²-hCG levels:
Start to rise about 11 days after conception (or 3β4 weeks after the last menstrual period).
Double approximately every 48 to 72 hours in early pregnancy.
Peak around 8β11 weeks, then decline and level off.
