The tone of the uterus during pregnancy: requires consultation gynecologist

The tone of the uterus during pregnancy increased tone of the uterus during pregnancy is not desirable - it poses a threat to its premature interruption.In addition, the uterine muscles are constantly tight squeeze blood vessels that carry to the fetus the nutrients and oxygen, so long hypertonicity of the uterus necessarily reflected on the state of the fetus.

mechanisms regulating the tone of the uterus during pregnancy

week after conception, the embryo is embedded in the uterine lining, and its shell villi begin to secrete a new hormone - human chorionic gonadotropin (hCG), whose main task - to stimulate additional production of the femalesex hormone progesterone.Progesterone is produced in the second half of the menstrual cycle temporary endocrine gland corpus luteum, located in the ovary.Under the influence of hCG corpus luteum of menstruation grows and becomes a corpus luteum of pregnancy, which produces a lot more progesterone.

main objective of progesterone - suppress locomotor activity and increased excitability of the muscles of the uterus, ie saline hypertonicity (increased tone), and to prevent spontaneous abortion.If progesterone is produced is not enough, the tone of the uterus increases, it creates a risk of miscarriage.

Physiological uterine hypertonus ensured by the fact that it increases the number of muscle fibers and the content of substances that ensure its contraction (calcium, protein actomyosin and other biologically active substances).It is preparing the body for childbirth.But this mechanism need not be soon, so progesterone Progesterone - norm and pathology Progesterone - norm and pathology not prevent the accumulation of these substances, but inhibits their activity.
