History of Polycystic Ovary Syndrome Although the first description of polycystic ovary syndrome (PCOS) is generally credited to Stein and Leventhal in 1935, it may have been observed as early as 1721, when the Italian scientist Antonio Vallisneri observed “young married peasant women, moderately obese and infertile, with two larger than normal ovaries, bumpy and shiny, whitish, just like pigeo...
BACKGROUND This study revisited the ultrasonographic diagnostic criteria of polycystic ovary syndrome (PCOS) and studied the relationship between the major hormonal and metabolic features of PCOS and the follicle number per ovary (FNPO). METHODS This prospective study included 214 women with PCOS compared with 112 women with normal ovaries. Main clinical, biological and ultrasonographic marke...
In a previous study, we showed that both the noradrenergic and cholinergic component of ovarian innervation is markedly changed in porcine cystic ovaries. The present study is aimed at elucidating the distribution pattern of substance P- (SP), calcitonin gene related peptide CGRP- and/or galanin (GAL)-containing nerve fibers within porcine cystic ovaries. The status polycysticus was induced by ...
OBJECTIVE We compared 12-month pregnancy and live birth rates in patients with polycystic ovarian disease undergoing 5-, 10-, and 15-point laparoscopic ovarian electrocauterization. METHODS This was a prospective, randomized study performed at the Dabirashrafi Fertility and Endoscopy Research Center, Tehran, Iran. The study included 187 patients with polycystic ovarian disease who were random...
Polycystic ovarian syndrome (PCOS) is a very common endocrine disorder in women of reproductive age. Nerve growth factor (NGF) may be involved in the pathogenesis of PCOS. In this study, we investigated the effect of Korean red ginseng extract (KRGE) on the ovarian morphology and NGF expression in an estradiol valerate (EV)-induced rat model. Polycystic ovaries were induced by a single intramus...
BACKGROUND Polycystic ovary syndrome (PCOS) is a common endocrinopathy, associated with metabolic abnormalities. Metabolic features of various phenotypes of this syndrome are still debatable. The aim of present study hence was to evaluate the metabolic and hormonal features of PCOS phenotypes in comparison to a group of healthy control. METHODS A total of 646 reproductive-aged women were rand...
Introduction: Increasing levels of free radicals in the ova reduce the quality of their fertilization. Investigations have revealed the elevated production of tissue and serum-free radicals in women with polycystic ovary syndrome. Sirtuin-3 is located in mitochondria and plays an important role in the deactivation of free radicals. This study aimed to investigate the expression of the Sirtuin-3...
