(Mathom, Shutterstock) Progestins are produced by the body sex hormones, the most important representatives of progesterone also Gelkörperhormon is. It prepares the endometrium for implantation of the fertilized egg and is therefore eye floaters essential for the occurrence eye floaters of pregnancy. Progesterone concentrations in the blood is an important indicator of a woman's fertility.
Progesterone is a female sex hormone. Its basic building block is - as with estrogens - cholesterol, so it belongs to the group of steroid hormones. It is also produced in the adrenal cortex in the ovaries in the so-called corpus luteum during pregnancy in the placenta (placenta) and to a small extent. From the other sex hormones progesterone in turn as estrogen and testosterone can be formed. How is the secretion eye floaters of progesterone regulated?
The distribution eye floaters will be made by no means uniform but depends on the menstrual eye floaters cycle. In the first half of the menstrual cycle - this so-called follicular phase lasts from the first day of menstruation to ovulation - the progesterone concentration in the blood is very low. From the time of ovulation is the concentration of progesterone, controlled by the hormone LH (luteinizing hormone) from the pituitary gland in the brain, increased significantly. Comes about a pregnancy, the concentration increases further. If the egg is not fertilized, the level remains during the luteal phase (time between ovulation and the onset of menstrual bleeding) increases constantly and passes on his sinking the next menstrual bleeding. What are the effects of progesterone?
While the mucous membrane grows in the first half of the cycle under the influence of estrogen in the uterus, eye floaters it is prepared in the second half by the action of progesterone on the implantation of the fruit. The vessels and glands of the endometrium and cells of the mucosa are active to provide nutrients to the embryo can.
In addition, progesterone causes a temperature rise in the body as well as a compression of the glands eye floaters in the breast. During pregnancy and to end the cycle of body temperature is therefore increased by 0.4-0.6 C, and the breasts eye floaters become larger due to the growth of the mammary glands. Thus, the body prepares in a pregnancy on milk production.
In addition, is stored in the tissues increased fluid under the influence of progesterone, which leads to an increase in body weight before the menstrual period and also accounts for a significant proportion of weight gain during pregnancy. Why the progesterone value is determined, and what to watch out for?
The determination of progesterone hormone investigation belongs to the woman to obtain evidence for a possible infertility, failure of the ovaries, irregular bleeding and other hormone-related diseases (eg, adrenogenital syndrome or the progesterone-secreting tumors). The ideal time to measure progesterone value is the 21 of the cycle or the 7th day after ovulation.
Important: eye floaters you can not prove the ovulation (ovulation) clearly based on the progesterone value! Neither the rise of progesterone nor the rising of the LH value (ovulation), or body temperature, not even the bursting of the follicular ultrasound are a direct proof of ovulation. For direct detection method you would ova, which are only 120 micro millimeters in size, can be detected by an imaging technique. Finally able to reliably detect ova only in the context of in vitro fertilization. What progesterone levels are normal?
The limits vary from lab to lab and therefore can not be specified as universal values. The limits of the Center for Laboratory Medicine, Medical University of Vienna are given as:
Pregnancy: first trimester of pregnancy (trimester): 13-44 ng / ml second trimester of pregnancy (trimester): 44-175 ng / ml When is the increased progesterone? adrenogenital syndrome eye floaters in (AGS): This is a disorder of hormone production in the adrenal glands, which is why it is over-production of male sex hormones and consequently to a masculinization. at cycle disorders in which the corpus eye floaters luteum regresses not the end of the second phase of the cycle and continuous progesterone produced in tumors that produce progesterone or its precursor hormone LH; the tumors in the pituitary gland (hypophysis), located in the ovaries or in the placenta. by taking medications containing progesterone (eg in the contraceptive pill or fertility treatment) When is a progesterone deficiency? in luteal weakness (corpus luteum insufficiency): This is a Funktionss
