Why pregnancy prolactin

Prolactin - a hormone of the anterior lobe of the pituitary gland, which is involved in the formation and functioning of the female reproductive system.During pregnancy, it increases the number as it is necessary for both mother and child.

Prolactin stimulates the growth and development of the mammary glands, the secretion of progesterone Progesterone - norm and pathology Progesterone - norm and pathology , which is especially needed at the beginning of pregnancy, as it prevents interruption.Prolactin is also involved in the water-salt metabolism, during pregnancy it regulates the volume and composition of the amniotic fluid.

But the problem is that a large number of prolactin prevents conception.Therefore, elevated prolactin in the planning of pregnancy - is a bad sign.

It inhibits the secretion of pituitary gonadotropins (TG), mainly follicle-stimulating hormone (FSH), resulting in no egg maturesovary and ovulation.That is, the menstrual cycle under the influence of a large amount of prolactin become irregular.

Why women can be increased prolactin

The reasons may be many, but obstetricians are divided into two unequal groups.It prolaktinprodutsiruyuschie benign pituitary tumor (prolactinoma), and all other causes.The fact that the prolactinoma - a fairly common tumor, which are always a cause of infertility.

The remaining causes of increased prolactin include severe kidney disease, liver and adrenal glands to decrease their function (diseases that are prolactin and without contraindication to pregnancy), marked reduction of thyroid function (hypothyroidism), polycystic ovarian tumor estrogenprodutsiruyuschie female genitalia andidiopathic hyperprolactinemia (prolactin reason for the increase is not clear).

can get pregnant at an elevated prolactin?

Today, the answer is clear: it is possible.But recently a pregnancy at an elevated prolactin was virtually impossible.Today produced drugs that stimulate the production of dopamine - a hormone and neurotransmitter, by which the hypothalamus suppresses lactotropic pituitary function.

For drugs of this series (Dofaminomimetiki) are bromocriptine (parlodel), cabergoline (Dostinex), lisuride.All of these drugs can be used in preparation for pregnancy.When hyperprolactinemia prescribers long courses, while prolactinoma - life, because these tumors are rare, and today operate only when complications or continued growth.Not all of these drugs can be taken during pregnancy.Pregnant women, if necessary, prescribe bromocriptine.

Dofaminomimetiki normalize prolactin levels, restore the menstrual cycle and fertility.At the same time women recovering throbbing TG secretion of pituitary, the release of luteinizing hormone (LH - it stimulates ovulation Ovulation - How to determine as accurately as possible? Ovulation - How to determine as accurately as possible? and support the second phase of the menstrual cycle) in the middle of the cycle, anovulatory cycles are eliminated, increasing the concentration of estrogenin the body disappear all the symptoms associated with a lack of female sex hormones and the male excess (overweight, edema, acne Acne: facial trouble Acne: facial trouble , hirsutism).

If elevated prolactin during pregnancy

Dofaminomimetiki after pregnancy in most cases canceled, as during pregnancy has not noted growth figures of prolactin in women with hyperprolactinemia, including tumors of the pituitary gland.But despite the lack of significant growth indicators prolactin, tumor growth can continue.Therefore, some women bromocriptine is prescribed and after pregnancy.

In general, the increased prolactin levels did not affect the course of pregnancy.

To date there is no evidence that prolactin caused miscarriage Miscarriage - why you lose the most precious thing? Miscarriage - why you lose the most precious thing? or any complications in childbirth.

Moreover, in pregnant women who received life-saving bromocriptine, increases the risk of death of a child after birth, due to the fact that he has not dealt lungs and he was unable to take the first breath.Such complications may develop due to the fact that light is not enough surfactant - surfactant that coats the inside of the alveoli and prevents them from sticking together.The maturation of surfactant involved prolactin.

Elevated prolactin during pregnancy is not terrible, but it prevents conception.
