    en.wikipedia.org/wiki/Human_chorionic_gonadotropin

    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. [1] [2] The presence of hCG is detected in some pregnancy tests (HCG pregnancy strip tests).

    Human Chronic Gonadotropin (hCG) is produced from the placenta after the implantation of a fertilized egg in the uterus. [2] Fused villous syncytiotrophoblast cells and extravillous invasive cytotrophoblast cells make hCG. [2] hCG promotes the production of corpus luteal progesterone [2] which helps to maintain the corpus luteum for producing ...

    en.wikipedia.org/wiki/Pregnancy_test

    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.

    A pregnancy test detects the presence of the pregnancy hormone human chorionic gonadotropin in a person’s body. The body doesn’t produce that hormone until several days after conception.

    The early embryo has 1–2 weeks in order to produce sufficient hCG in order to stabilize the endometrial lining to allow for blastocyst attachment. The dramatic increase in trophoblastic and corpus luteal hCG synthesis signals both blastocyst [5] and corpus luteal [6] production of P4, crucial for the maintenance of the endometrium.

  7. Gonadotropin - Wikipedia

    en.wikipedia.org/wiki/Gonadotropin

    Gonadotropins are glycoprotein hormones secreted by gonadotropic cells of the anterior pituitary of vertebrates. [1] [2] [3] This family includes the mammalian hormones follicle-stimulating hormone (FSH) and luteinizing hormone (LH), the placental/chorionic gonadotropins, human chorionic gonadotropin (hCG) and equine chorionic gonadotropin (eCG), [3] as well as at least two forms of fish ...

    The progesterone is first produced by the corpus luteum and then by the placenta in the second trimester. Women also experience increased human chorionic gonadotropin (β-hCG), which is produced by the placenta. [3]
