The embryo upregulates hCG, drives growth of the cell, and upregulates P4 production driving development. hCG and P4 direct changes in the mother to enable successful pregnancy (see below) via upregulation of specific hormones that act to direct both endocrinological and biological changes within the mother for successful pregnancy.
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.
Growth hormone (GH) or somatotropin, also known as human growth hormone (hGH or HGH) in its human form, is a peptide hormone that stimulates growth, cell reproduction, and cell regeneration in humans and other animals. It is thus important in human development.

Expectant parents have a lot to look forward to through the duration of a pregnancy - Lamaze classes, for one. "Nothing can prepare you for the battle that is childbirth, unless of course you've ...
Prolactin and insulin-like growth factor binding protein are two examples of the hormones and growth factors that relaxin can stimulate the secretion of. [21] Preprorelaxin is the collective term for the signal peptide , B chain, C peptide, and A chain found in the coding area of human relaxin genes. [ 22 ]
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 ...
Poor posture occurs naturally from the stretching of the woman's abdominal muscles as the fetus grows. These muscles are less able to contract and keep the lower back in proper alignment. The pregnant woman has a different pattern of gait. The step lengthens as the pregnancy progresses, due to weight gain and changes in posture.
