Combined administration of gonadotropin-releasing hormone, progesterone, and meloxicam is an effective treatment for the repeat-breeder cow
(2009)In practice, the etiologic treatment of the repeat-breeder cow is nearly infeasible. In this study, we tested the hypothesis that a combined treatment would benefit the conception rate of repeat-breeder cows. The components ... -
Early embryo losses, progesterone and pregnancy associated glycoproteins levels during summer heat stress in dairy cows
(2021)Objectives of this study were to characterize the effects of heat stress on pregnancy associated glycoproteins (PAG) and progesterone and its involvement in embryo survival. In trial 1, blood samples collected from days ... -
Effect of adiponectin on estradiol and progesterone secretion from human luteinized granulosa cells in vitro
(2021)Ιnformation on the role of adiponectin in human ovarian steroidogenesis is limited. The present study aimed to investigate the effect of different doses of adiponectin on the secretion of estradiol and progesterone by human ... -
The Effect of Metformin on the Endometrium of Women with Polycystic Ovary Syndrome
(2019)Objectives: To investigate the effect of metformin on endometrial receptivity in women with polycystic ovary syndrome (PCOS). Methods: Twenty volunteer women with polycystic ovaries and oligomenorrhea were prospectively ... -
The effect of repeated follicular aspiration on the onset of puberty and growth rate of winter- or autumn-born lambs
(2009)The effects of follicular aspiration for oocyte retrieval on the attainment of puberty and growth rate were studied in winter-born (9 treated and 6 control) and autumn-born (5 treated and 5 control) ewe lambs. In the treated ... -
Effect of resistin on estradiol and progesterone secretion from human luteinized granulosa cells in culture
(2019)Information on the role of resistin on steroidogenesis is limited to animal studies. The aim of this study was to investigate the effect of various doses of resistin on estradiol and progesterone secretion from human ... -
Endocrinological profile and follicular development in cyclic ewes subjected to repeated ovum pick-up
(2013)Blood concentrations of progesterone, FSH and oestradiol in Karagouniko ewes subjected to laparoscopic ovum pick-up (OPU) at specific stages of induced oestrous cycle, were measured. Twenty-four cyclic ewes were randomly ... -
Exogenous progesterone for LH surge prevention is redundant in ovarian stimulation protocols
(2021)During ovarian stimulation for IVF–embryo transfer treatment, a premature LH surge may lead to progesterone elevation that disrupts endometrial maturation and affects the probability of pregnancy following fresh embryo ... -
Ghrelin suppresses the GnRH-induced preovulatory gonadotropin surge in dairy heifers
(2016)Ghrelin, a known growth hormone (GH) secretagogue, alters gonadotropin secretion in many species. Our objectives were to study the effects of ghrelin, on GH, LH, FSH secretion, and on luteal function of the ensuing estrous ... -
Oocyte pick-up in juvenile lambs affects neither onset of puberty nor their future fertility
(2006)A study was designed to evaluate whether the time of onset of puberty and fertility of young ewe lambs would be affected by oocyte pick-up conducted in single or repeated sessions during the first months of lambs' live. ... -
A study on ghrelin and LH secretion after short fasting and on ghrelin levels at perioestrual period in dairy cattle
(2019)In two experiments, we studied (a) the changes of LH secretion in heifers under different feeding schedules and (b) total ghrelin concentration at oestrus in cows and heifers. In experiment one, synchronized heifers were ...
