    Progestin challenge , or progesterone withdrawal test is a test used in the field of obstetrics and gynecology in order to evaluate a patient who is experiencing amenorrhea . Due to readily available assays to measure serum estradiol levels, this test is now rarely used. ref cite web url http emedicine.medscape.com article 276110 diagnosis title eMedicine Amenorrhea, Secondary Differential Diagnoses & Workup accessdate 2010 05 02 publisher eMedicine.com ref The test is performed by administering progesterone orally in the form of medroxyprogesterone acetate Provera , or intramuscularly. If the patient has sufficient serum estradiol greater than 50 pg mL then withdrawal bleeding should occur 2 7 days after the progestin is finished, indicating that the patient s amenorrhea is due to anovulation . However, if no bleeding occurs after progesterone withdrawal, then the patient s amenorrhea is likely to be due to either a low serum estradiol, b hypothalamic pituitary axis dysfunction or c a problem with the uterine outflow tract, such as stenosis of uterine cervix cervical stenosis or uterine synechiae Asherman s syndrome . In order to distinguish between hypoestrogenism or a uterine outflow tract problem, estrogen may be administered followed by a course of progestin in order to induce withdrawal bleeding. If the patient experiences withdrawal bleeding with the combined estrogen progestin therapy, then the amenorrhea is likely due to low estrogen. ref cite web url http www.advancedfertility.com progesterone withdrawal test.htm title Progesterone Withdrawal Test accessdate 2010 05 02 publisher Advanced Fertility Center of Chicago ref References reflist Category Female genital procedures ...   more details

  1. Fern test

    unreferenced date October 2011 Fern test refers to detection of a characteristic fern like pattern of cervical mucus when a specimen of cervical mucus is allowed to dry on a glass slide and is viewed under a low power microscope. Fern test is used to provide indirect evidence of ovulation and fertility, however this test does not predict the time of ovulation. Ferning is due to the presence of sodium chloride in the mucus under estrogen effect. When high levels of estrogen are present, just before ovulation, the cervical mucus forms fern like patterns due to crystallization of sodium chloride on mucus fibers. This pattern is known as arborization or ferning . When progesterone is the dominant hormone, as is just after ovulation, fern pattern is no longer discernible. Fern pattern is completely absent by 22nd day of cycle. Disappearance of fern pattern after 22nd day suggests ovulation and its persistence throughout menstrual cycle suggests an ovulation infertility .

This enzyme belongs to the family of transferase s, to be specific, the sulfotransferases, which transfer sulfur containing groups. The systematic name of this enzyme class is 3 phosphoadenylyl sulfate estrone 3 sulfotransferase . Other names in common use include 3 phosphoadenylyl sulfate estrone 3 sulfotransferase , estrogen sulfotransferase , estrogen sulphotransferase , oestrogen sulphotransferase , and 3 phosphoadenylylsulfate oestrone sulfotransferase . This enzyme participates in androgen and estrogen metabolism and sulfur metabolism .

This is all due to a lack of the reproductive hormone estrogen . The most common cause of vaginal atrophy is the decrease in estrogen which happens naturally during perimenopause, and increasingly so in post menopause . However this condition can sometimes be caused by other circumstances. The symptoms can include vaginal soreness and itching, as well as painful intercourse, and bleeding after sexual intercourse. The shrinkage of the tissues can be extreme enough to make intercourse impossible. Symptoms and signs Genital symptoms include dryness, itching, burning, soreness, pressure, white discharge, malodorous discharge due to infection, painful sexual intercourse, bleeding after intercourse. In addition, sores and cracks may occur spontaneously. Atrophic vaginitis is a cause of Postmenopausal bleeding PMB . Urinary symptoms include painful urination, blood in the urine, increased frequency of urination, incontinence, and increased likelihood and occurrence of infections. Incidence and causes A large number of postmenopausal women who are not using topical estrogen have at least some degree of vaginal atrophy however, many women do not actively ask that medical attention be paid to this, possibly because it is naturally caused, or because of the taboo that still exists surrounding aging and sexuality. Citation needed date January 2010 The cause of vaginal atrophy is usually the normal decrease in estrogen as a result of menopause. Other causes of decreased estrogen levels are decreased ovarian functioning due to radiation therapy or chemotherapy, immune disorder, removal of the ov ...   more details
