Background. the aim of this study was to evaluate the action of tamoxifen on the endometrium in stales of chronic anovulation.Methods. Thirty-eight rats inducted to persistent estrous (testosterone propionate) confirmed ...
Effects of different doses of nandrolone decanoate on estrous cycle and ovarian tissue of rats after treatment and recovery periods
(2015-10-01)
This study tested the hypothesis that different doses of nandrolone decanoate (ND) will cause changes in the estrous cycle and ovarian tissue of adult rats; and investigated the duration of the recovery period that is ...
Alterations in the insulin signaling pathway in bovine ovaries with experimentally induced follicular persistence
(Elsevier Science Inc., 2020-12)
Reproductive diseases in dairy cows as cystic ovarian disease (COD) represent a major problem that impacts on dairy production. COD is characterized by anovulation, persistence of the dominant follicle, and interruption ...
A conditional tetracycline-regulated increase in gamma amino butyric acid production near luteinizing hormone-releasing hormone nerve terminals disrupts estrous cyclicity in the rat
(ENDOCRINE SOC, 2001-05)
Gamma amino butyric acid (GABA) is the main inhibitory neuro-transmitter controlling LH-releasing hormone (LHRH) secretion in the mammalian hypothalamus. Whether alterations in GABA homeostasis within discrete regions of ...
Intraovarian excess of nerve growth factor increases androgen secretion and disrupts estrous cyclicity in the rat
(ENDOCRINE SOC, 2000-03)
A single injection of estradiol valerate induces a form of cystic ovary resembling some aspects of the human polycystic ovarian syndrome. Preceding the development of follicular cysts, there is an increase in intraovarian ...
Hemodynamic changes detected by Doppler ultrasonography in the ovaries of cattle during early development of cystic ovarian disease
(Elsevier Science, 2019-08)
A common reproductive diseases in dairy cattle is Cystic Ovarian Disease. To study its development, there was use of an experimental model of follicular persistence to detect hemodynamic changes occurring in ovaries by ...
