in the present report, diagnosis and treatment of a case with follicular ovarian cysts in a 5-year-old persian queen cat is described. in response to palpation of spines, the queen cat presented herself in lordosis and danced up and down with her rear legs. trans-abdominal ultrasonography examination showed 2 cysts in the left ovary of the queen. serum estrogen assay indicated elevated level o...
Long protocol of Gonadotropin-Releasing Hormone-analougue (GnRH-a) can result in the formation of ovarian cyst by the transient initial stimulatory effect which increases the levels of both follicle-stimulating hormone (FSH) and luteinizing hormone (LH). These cysts require surgical drainage or result in poor ovarian response. Ovarian cyst formation can be prevented by taking oral contraceptive...

The aim of the present study was to induce ovarian cysts experimentally in cattle using ACTH and to closely examine the role of LH pulse frequency in ovarian cyst formation. Five regularly cycling Holstein-Friesian heifers (15-18-month-old) were used. Ovaries were scanned daily using an ultrasound scanner with a 7.5 MHz rectal transducer. Daily blood samples were obtained via tail venepuncture ...
Background & Aim: The indications for fine needle aspiration(FNA) cytology of ovarian cysts are controversial. Some authors contend that the procedure is never justified since diagnostic accuracy of the method is low. The others contend that FNA of the ovarial lesion has a useful role in the evaluation of persistant ovarian lesion in the premenopausal women who wish to preserve fertility. T...
Ovarian follicular growth and development are regulated by extraovarian and intraovarian factors, which influence granulosa cell proliferation and differentiation. However, the molecular mechanisms that drive follicular growth are not completely understood. Ovarian follicular cysts are one of the most common causes of reproductive failure in dairy cattle. Nevertheless, the primary cause of cyst...
The aim of the present study was to examine the LH response to exogenous estradiol in 4 heifers with ACTH-induced ovarian follicular cysts. During the control experiment, administration of estradiol 24 hr after PGF2alpha in luteal phase heifers resulted in a LH response in all 4 heifers. The LH response was obtained between 16-20 hr after estradiol administration. The peak LH concentration (Mea...
Two experiments were conducted to determine if adrenal secretion of steroids differed between cows that formed ovarian follicular cysts and normal cycling cows. In experiment 1, lactating Jersey and Holstein cows were diagnosed as having ovarian follicular cysts (follicle diameter >or=20 mm) by rectal palpation. Following diagnosis, ovaries were examined by transrectal ultrasonography three tim...
