Exercise differentially affects metabolic functions and white adipose tissue in female letrozole- and dihydrotestosterone-induced mouse models of polycystic ovary syndrome
(Elsevier, 2017-06-15)
Here we hypothesized that exercise in dihydrotestosterone (DHT) or letrozole (LET)-induced polycystic
ovary syndrome mouse models improves impaired insulin and glucose metabolism, adipose tissue
morphology, and expression ...
High-frequency electrical modulation of the superior ovarian nerve as a treatment of polycystic ovary syndrome in the Rat
(Frontiers Media SA, 2018-05-01)
The polycystic ovary syndrome (PCOS) is the most prevalent ovarian pathology in women, with excessive sympathetic activity in the superior ovarian nerve (SON) playing an important role in inducing the PCOS symptoms in the ...
Gestational sympathetic stress programs the fertility of offspring: a rat multi-generation study
(MDPI, 2022)
The exposure to sympathetic stress during the entire period of gestation (4 degrees C/3 h/day) strongly affects the postnatal reproductive performance of the first generation of female offspring and their fertility capacity. ...
Diagnóstico del Síndrome de Ovario Poliquístico: nuevos fenotipos, nuevas incógnitas
(2009)
Polycystic ovarian syndrome (PCOS), includes a wide spectrum of
clinical symptoms and signs. Three different diagnostic classifications have been proposed to
define this disease. The first one, published in 1990, known ...
Epigenética del síndrome de ovario poliquístico
(Sociedad Médica de Santiago, 2017)
Polycystic ovarian syndrome (PCOS) is an endocrine and metabolic
dysfunction, highly prevalent in women in their reproductive years.
Hyperandrogenism, oligo-ovulation, polycystic ovarian morphology are
the main features ...
Locus coeruleus mediates cold stress-induced polycystic ovary in rats
(ENDOCRINE SOC, 2008-06)
Previous reports about the rat ovary have shown that cold stress promotes ovarian morphological alterations related to a polycystic ovary (PCO) condition through activation of the ovarian sympathetic nerves. Because the ...
Immature rat ovaries become revascularized rapidly after autotransplantation and show a gonadotropin-dependent increase in angiogenic factor gene expression
(1994)
When the ovaries of 23-day-old juvenile rats are transplanted to an ectopic site, they recover within 1 week the ability to control gonadotropin secretion via steroid negative feedback. Vascular corrosion casting followed ...
Pregnancy outcomes in women with polycystic ovary syndrome in two Latin American populations
(Taylor & Francis, 2018)
Pregnancy complications and obstetric outcomes were compared in 80 Chilean (PPCOSCh) and 70 Argentinian (PPCOSAr) pregnant women. Reference groups of Chilean and Argentinian normal pregnant women from the same antenatal ...
TrkB receptors are required for follicular growth and oocyte survival in the mammalian ovary
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2004-03-15)
Although it is well established that both follicular assembly and the initiation of follicle growth in the mammalian ovary occur independently of pituitary hormone support, the factors controlling these processes remain ...
