Progesterone is produced in the corpus luteum during the luteal phase of the menstrual cycle (the last of the phases, begins after ovulation and ends just before menstruation. It usually lasts fourteen <\/span>days) and during pregnancy. Together with oestrogen, it is the most important female sex hormone.<\/span><\/p>\n It is also produced in the adrenal cortex and testes, as well as in the placenta and central nervous system. Progesterone acts on cells that have receptors <\/span>progesterone. Elevated or decreased progesterone can interfere with basic <\/span>bodily functions.<\/span><\/p>\n<\/p>\n Progesterone produced during the luteal phase allows implantation of the embryo in the mucosa uterus. It is also responsible for the correct maintenance of pregnancy and influences cervical mucus -. <\/span>reduces its permeability to sperm. <\/span><\/p>\n Decrease in progesterone levels <\/span>results in the exfoliation of the endometrium (menstruation). The woman then enters <\/span>the beginning of the follicular phase, which lasts about fourteen days (if your cycle lasts about 28 days) and <\/span>ends on the day of ovulation. Progesterone levels then rise, indicating the release of the <\/span>egg cell. <\/span>Progesterone in the normal range also reduces the contractility of the uterine muscle. Overall - <\/span>is responsible for the correct implantation of the fertilised egg cell. Its action <\/span>are also controlled by other hormones - mainly luteinizing hormone which is produced by the <\/span>pituitary gland. (1)<\/span><\/p>\n<\/p>\n The concentration of progesterone in women is constantly changing. It depends mainly on the phase of the cycle of the menstrual cycle, i.e. the follicular, perovulatory and luteal periods. Therefore, the correct <\/span>progesterone levels are as follows:<\/span><\/p>\n<\/p>\n Progesterone standards in women<\/span><\/p>\n \u25cf follicular phase from 0.28 to 0.72 ng\/ml;<\/p>\n \u25cf perovulatory phase from 0.64 to 1.63 ng\/ml;<\/p>\n \u25cf luteal phase from 4.71 to 18.0 ng\/ml.<\/p>\n<\/p>\n During the last phase, the progesterone norm is significantly higher than the previous phases. During the phase The luteal corpus luteum is formed in the ovary. This is when the cells of the endometrium in the <\/span>The woman's body accumulates nutrients that are essential for the initial <\/span>the period after fertilisation of the ovum and implantation of the embryo. (2)<\/span><\/p>\n<\/p>\n Symptoms of low progesterone levels can include menstrual disorders, i.e. lack of menstrual periods, amenorrhoea (menorrhagia) and infrequent menstruation <\/span>(oligomenorrhoea). Women with low progesterone levels are also more likely to find <\/span>painful menstruation (dysmenorhea). During dysmenorrhoea there are <\/span>increased blood loss of more than 80 ml or bleeding may last more than seven days. <\/span>Painful menstruation is characterised by excessive uterine contraction activity. <\/span>Women are then accompanied by severe lower abdominal pain. Infrequent menstruation is, as the <\/span>the name suggests, the sporadic occurrence of menstruation. The absence of menstruation, on the other hand, can be <\/span>also a consequence of systemic disease or dysfunction of the reproductive system. With each <\/span>disorder should be seen immediately by a gynaecologist. (3) <\/span><\/p>\n Below-normal progesterone can also cause excessive hair loss and dry skin. <\/span>Low progesterone is very detrimental to women who want to get pregnant.<\/strong><\/p>\n<\/p>\n Elevated progesterone levels usually manifest as swelling, varicose veins and water retention in the body. This can result from various disorders, for example <\/span>liver failure, polycystic ovarian syndrome, adrenal-gonadal syndrome <\/span>and cancer of the adrenal gland or ovaries. High progesterone can also be indicative of <\/span>the occurrence of cysts on the ovaries.<\/span><\/p>\n<\/p>\n Progesterone testing is performed by means of a blood draw from the ulnar vein. <\/p>\n<\/p>\n Preparation for progesterone testing<\/span><\/p>\n You should report to the collection centre on an empty stomach in the morning. <\/p>\n<\/p>\n Furthermore, the timing of examinations in women must be correlated with medical indications and the phase of the menstrual cycle:<\/p>\n<\/p>\n Testing of the progesterone standard is reimbursed by the National Health Fund. It can also be done commercially with a charge of around 50-60 PLN. You usually wait one day for the results. Afterwards, it is essential to consult a general practitioner, who will make a diagnosis and provide appropriate treatment.<\/p>\n<\/p>\n 1. https:\/\/core.ac.uk\/download\/pdf\/268474825.pdf <\/p>\n 2. http:\/\/yadda.icm.edu.pl\/baztech\/element\/bwmeta1.element.baztech-article-BPL2-0020-0043<\/span><\/p>\n 3. https:\/\/www.mp.pl\/pacjent\/objawy\/253859,zaburzenia-miesiaczkowania<\/p>\n<\/p>\n Dr Blanka Malczewska<\/strong> - specialist gynaecologist-obstetrician from the InviMed clinic in Gdynia <\/span><\/p><\/p>","protected":false},"parent":0,"menu_order":0,"template":"","blog-category":[],"blog-tags":[],"class_list":["post-247501","blog","type-blog","status-publish","hentry"],"acf":{"blog_clinics":""},"yoast_head":"\nWhat are the functions of progesterone?<\/h2>\n
