full textPremature Ovarian Failure: A Critical Condition in The Reproductive Potential with Various Genetic Causes
Premature ovarian failure (POF) is identified as a heterogeneous disorder leading to amenorrhea and ovarian failure before the age of 40 years. The first known symptom of the disease is having irregular menstrual periods. The phenotype appearance of POF depends significantly on the variations in hormones. Low levels of gonadal hormones (estrogens and inhibins) and increased level of gonadotropi...

Premature ovarian failure (POF) is a heterogeneous disorder, defined as menopause under age 40 years. The prevalence is 1%; POF before age 30 years is much less common. Chromosomal causes have long been recognized - visible deletions of the X chromosome, 45,X/46,XX mosaicism, and autosomal rearrangements (balanced translocations). Toxins or iatrogenic causes (e.g., chemotherapeutic agents) are ...
full textI-36: The Necessity of Genetic Screening in Premature Ovarian Failure and Diminished Ovarian Reserved Patients
Variability in the subfertile patient population excludes the possibility of a single approach to controlled ovarian stimulation (COS) covering all the requirements of a patient. Modern medical science has made great advances in the understanding and the development of new drugs, treatment options and quantitative methods that can identify single patient characteristics. Factors that reduce fol...

Premature Ovarian Failure (POF) defined as functional stop of ovaries before the age of 40. It is a common cause of infertility in women that characterized by primary or secondary amenorrhea, high gonadotropin levels and estrogen level declining in patients. Factors that reduce follicle or defect in the follicle growth stimulating mechanism defined as numerous complication factors that they can...
full textGenetic disorders in premature ovarian failure.
This review presents the genetic disorders associated with premature ovarian failure (POF), obtained by Medline, the Cochrane Library and hand searches of pertinent references of English literature on POF and genetic determinants cited between the year 1966 and February 2002. X monosomy or X deletions and translocations are known to be responsible for POF. Turner's syndrome, as a phenotype asso...
