called the pregnancy hormone progesterone, because it helps women to conceive, carry and give birth to a child.If the woman's body there is a lack of this hormone, then it violated the reproductive function.But today, such a state of learned to treat.
disruption of the menstrual cycle when progesterone is low
progesterone - a hormone that provides hormonal support for the second phase of the menstrual cycle.If it is not enough, then there are dysfunctional uterine bleeding (DUB).All DMK can be divided into two large groups - anovulatory and ovulatory.
Anovulatory DUB develop during the menstrual cycle, which is not accompanied by ovulation Ovulation - How to determine as accurately as possible? , ie the release of an egg from the ovary.The egg at the same time after reaching maturity remains in the ovary and emits large amounts of female hormones estrogen.Under the influence of estrogens mucous membrane of the uterus (the endometrium) is significantly increased in volume.In this secon
ovulatory MQM develop in an inferiority of the corpus luteum, which releases progesterone or a little prematurely ends its operation.When this blood is relatively increased estrogen content, which expands under the influence of the endometrium.The lack of progesterone leads to uneven and prolonged rejection of the endometrium, which is accompanied by the slim long bloody discharge after normal menstruation.
Treatment of menstrual disorders is to appoint hormones.Depending on the cause DMC appointed or progesterone, or a combination with estrogens.
Pregnancy and low progesterone
During pregnancy, progesterone Progesterone - norm and pathology is the principal hormone that maintains this state.To the corpus luteum of the ovary to secrete progesterone in sufficient quantities in the first half of pregnancy, the embryo is produced by a special shell hormone - human chorionic gonadotropin (hCG).HCG is a permanent task of stimulating the synthesis of progesterone.After the 16th week of pregnancy the synthesis of hormones incurs matured placenta, there is no need for HCG and the amount of it is gradually reduced.
Lack of progesterone immediately affects pregnancy.First of all, it creates the threat of premature pregnancy termination.This can happen due to the fact that the tone of the muscles of the uterus and the embryo can be simply thrown out of its cavity.Progesterone is actively inhibits motor activity of smooth muscles of the uterus, thus preventing miscarriage Miscarriage - why you lose the most precious thing? .Such action of progesterone has a number of side effects, as the reflex is inhibited and the motor activity of smooth muscles of internal organs other pelvic and abdominal cavity.In the gastrointestinal tract it leads to chronic constipation, it appears in the biliary tract and bile stasis formation of stones and so on.
Progesterone also contributes to reduced immunity - and the physiological response aimed at preserving the pregnancy.Immunosuppression is necessary to the mother of the fetus is not rejected by the body consisting of the foreign protein.Progesterone inhibits aggression by the mother's body in relation to the fetus.But the function of progesterone is backward, the negative side: lowered immunity leads to the development of infections.Very often in pregnant women develop a fungal infection caused by yeast fungi of the genus Candida.
Progesterone helps the woman in the second half of pregnancy to prepare for childbirth.Under the influence of progesterone soften the ligaments and tendons, allowing the bones of the pelvis to change their configuration during the passage of the fetus through the birth canal.
What if progesterone in the blood of pregnant women are not
Obstetricians today successfully cope with such conditions.Pregnant women are prescribed medications that contain natural or synthetic progesterone (eg utrozhestan Utrozhestan - corrects the deficiency of progesterone , djufaston) long courses throughout the first trimester, and in some cases both.It allows a woman to carry and give birth to a healthy baby.
