  2. Human chorionic gonadotropin - Wikipedia

    en.wikipedia.org/wiki/Human_chorionic_gonadotropin

    Human chorionic gonadotropin is a glycoprotein composed of 237 amino acids with a molecular mass of 36.7 kDa, approximately 14.5kDa αhCG and 22.2kDa βhCG. [4]It is heterodimeric, with an α (alpha) subunit identical to that of luteinizing hormone (LH), follicle-stimulating hormone (FSH), thyroid-stimulating hormone (TSH), and a β (beta) subunit that is unique to hCG.

    It begins between the 4 and 8 weeks of pregnancy and usually subsides by 14 to 16 weeks. The exact cause of nausea is not fully understood but it correlates with the rise in the levels of human chorionic gonadotropin, progesterone, and the resulting relaxation of smooth muscle of the stomach.

  4. Pregnancy hormones - Wikipedia

    en.wikipedia.org/wiki/Pregnancy_hormones

    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 ...

  5. 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 ...

    Estrogen, progesterone, and human chorionic gonadotropin (hCG) levels throughout pregnancy. Estrogen, progesterone, and 17α-hydroxyprogesterone (17α-OHP) levels during pregnancy in women. [ 1 ] The dashed vertical lines separate the trimesters .

  7. Neohormone - Wikipedia

    en.wikipedia.org/wiki/Neohormone

    Human chorionic gonadotropin (hCG) is a hormone produced by the placenta during pregnancy. [5] This hormone stimulates the Corpus Luteum to produce progesterone to maintain pregnancy. [5] Therefore, hCG plays a role in human maternal recognition of pregnancy. [5]

  8. Endocrinology of reproduction - Wikipedia

    en.wikipedia.org/wiki/Endocrinology_of_reproduction

    Human chorionic gonadotropin (hCG), progesterone, 17β-estradiol, endorphins and gonadotropin-releasing hormone (GnRH) synthesis are rapidly upregulated by the developing embryo following fertilization of the ovum. [1] [2] [3] During early embryonic development, paracrine/juxtacrine signaling of hCG induces blastulation and neurulation.

  9. Chorionic gonadotropin beta - Wikipedia

    en.wikipedia.org/wiki/Chorionic_gonadotropin_beta

    Choriogonadotropin subunit beta (CG-beta) also known as chorionic gonadotrophin chain beta is a protein that in humans is encoded by the CGB gene. [ 3 ] [ 4 ] [ 5 ] This gene is a member of the glycoprotein hormone beta chain family and encodes the beta 3 subunit of chorionic gonadotropin (CG).
