The rest degenerate over the years. During the reproductive years, a gland in the brain generates chaste hormones vitex that cause a new egg to be released from its follicle each month. As the follicle develops, it produces the sex hormones estrogen and progesterone, chaste which thicken the lining of the uterus. This vitex enriched lining is prepared to receive and nourish a fertilized egg, which could develop into a baby. If fertilization does not occur, estrogen and progesterone levels drop, the lining of the uterus breaks down, and menstruation occurs. For reasons unknown, your ovaries gradually begin to decline in hormone production during your mid-30s. In your late 40s, the process accelerates and hormones fluctuate more, causing irregular menstrual cycles and unpredictable episodes of bleeding. By your early to chaste mid-50s, periods finally end altogether. However, estrogen production does not completely stop. The ovaries decrease their output significantly, but still may produce a small amount. Progesterone, the other female hormone, works during the second half of the menstrual cycle to create a lining in the uterus as a viable home for an egg, and to shed the lining if the egg is not fertilized. One note of caution: although irregular menstrual vitex periods are common as you get closer to menopause, they chaste can also be a symptom of uterine abnormalities or uterine cancer. If your periods stop for several months and then start again with heavy bleeding or if you start bleeding after menopause, consult with an obstetrician/gynecologist as soon as possible for an evaluation. Be sure to mention vitex any menstrual irregularities during regular check-ups. A uterine biopsy or vaginal ultrasound are the only ways to evaluate if irregular symptoms are abnormal. The makers of include this section as a resource to our visitors. We do this not only to supply more information about our ingredients, but also to include various points chaste of view and facts we think may vitex be of interest and not readily seen in other media. It does not mean that the publications endorse our product. chaste We have listed some research we are not able to "reprint" on this site, either because it was too expensive for the rights or we were unable to find the author or obtain the permission. vitex That research will not be a "link" but can be obtained chaste at a library. The use in disturbances of the female genital system was first reported more than two thousand years ago. Nowadays ethanolic extracts from the fruit are used for vitex the treatment of mastopathy, premenstrual syndrome and luteal insufficiency-complaints caused by a mild or latent hyperprolactinemia. The mode of action of Vitex agnus-castus extracts was studied in vitro using primary cultures from rat pituitaries as a test system. A dose dependent chaste reduction of prolactin secretion was observed. The effect could be blocked by the dopamine-receptor vitex antagonist, haloperidol, confirming a dopamine agonistic activity of the drug. The prolactin lowering effect of Vitex agnus-castus was also found in in vivo experiments in rats. Clinical studies in patients with premenstrual syndrome, luteal insufficiency, and mastopathy show a simultaneous decrease in the clinical syndrome score and prolactin levels. In the monograph of the Commission E, a daily dosage of 30-40mg of an ethanolic extract of the fruit of Vitex agnus-castus is recommended for the treatment chaste of the premenstrual syndrome, luteal phase defects and other disturbances of the menstrual cycle, as well for the treatment of mastodynia vitex .
