Hormone for the maternal recognition of pregnancy
- Human chorionic gonadotropin (hCG) is a hormone for the maternal recognition of pregnancy produced by trophoblast cells that are surrounding a growing embryo (syncytiotrophoblast initially), which eventually forms the placenta after implantation. The presence of hCG is detected in some pregnancy tests (HCG pregnancy strip tests).

人绒毛膜促性腺激素 （英語： Human chorionic gonadotropin ，简写为 hCG ）是一种 糖蛋白 激素 ，由 胎盤 的 滋胚層 細胞分泌，主要功能是刺激 黃體 ，有利於 雌激素 和 黃體酮 持續分泌，以促進子宮蛻膜形成，使 胎盤 生長成熟。 胚胎 一旦 著床 後， 滋胚層 細胞就會開始分泌hCG，所以可以透過血中或尿中hCG值來判斷妊娠。 由244个 氨基酸 残基组成，分子量36.7kDa，大小7.5×3.5×3纳米。 为异源二聚体，其α亚基与 促黄体素 （LH）、 促滤泡素 （FSH）和 促甲狀腺激素 （TSH）的α亚基相同，其β亚基则不同。 α亚基含92个氨基酸残基，β亚基含145个氨基酸残基。

Identified in the early 20th century, human chorionic gonadotropin (hCG) is a glycoprotein hormone that rises quickly in the first few weeks of pregnancy, typically reaching a peak at 8- to 10-weeks gestational age. [4] [5] hCG is produced by what will become the placenta.
2023年8月14日 · 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.
2017年5月14日 · 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.
