Effect of progestagen pretreatment on fertility of ewes
Valasi, I.; Theodosiadou, E.; Deligiannis, C.; Papadopoulos, S.; Kantas, D.; Amiridis, G. S. (2010) -
The effect of repeated follicular aspiration on the onset of puberty and growth rate of winter- or autumn-born lambs
Valasi, I.; Fthenakis, G. C.; Prassinos, N. N.; Menegatos, I.; Grigoropoulou, V.; Deligiannis, C.; Vainas, E.; Amiridis, G. S. (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 the time of artificial insemination on fertility of short-term progestagen pre-treated Karagouniko and Chios ewes
Papadopoulos, S.; Valasi, I.; Deligiannis, C.; Theodosiadou, E.; Kantas, D.; Goulas, P. (2012) -
Endocrinological profile and follicular development in cyclic ewes subjected to repeated ovum pick-up
Valasi, I.; Theodosiadou, E.; Fthenakis, G. C.; Papanikolaou, T.; Deligiannis, C.; Kalogiannis, D.; Chadio, S.; Amiridis, G. S. (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 ... -

Valasi, I.; Papanikolaou, T. H.; Tsiligianni, T. H.; Theodosiadou, E.; Kantas, D.; Deligiannis, C.; Amiridis, G. S. (2008) -
Ghrelin decreases pituitary response to GnRH in superovulated ewes
Dovolou, E.; Chadio, S.; Messinis, I. E.; Rekkas, C.; Deligiannis, C.; Kalogiannis, D.; Amiridis, G. S. (2013) -
Human ghrelin decreases pituitary response to GnRH in superovulated ewes
Dovolou, E.; Chadio, S.; Messinis, I. E.; Rekkas, C. A.; Deligiannis, C.; Kalogiannis, D.; Amiridis, G. S. (2013)In addition to its metabolic role, ghrelin has been found to suppress luteinizing hormone secretion in many species acting mainly at the hypothalamic level. The objectives of the present study were to test the hypothesis ... -
Luteal stage dependence of pituitary response to gonadotrophin-releasing hormone in cyclic dairy ewes subjected to synchronisation of ovulation
Amiridis, G. S.; Valasi, I.; Menegatos, I.; Rekkas, C.; Goulas, P.; Papanikolaou, T.; Deligiannis, C. (2005)Possible hormonal aberrations precluding conception or maintenance of pregnancy in dairy ewes subjected to ovulation synchronisation were investigated in this study. The pituitary response to exogenous gonadotrophin-releasing ... -
Synchronization of ovulation and fixed time intrauterine insemination in ewes
Deligiannis, C.; Valasi, I.; Rekkas, C. A.; Goulas, P.; Theodosiadou, E.; Lainas, T.; Amiridis, G. S. (2005)A novel method for oestrus-ovulation synchronization in sheep followed by fixed time insemination is presented herewith. Mature dry ewes (n = 28) of Karagouniko breed being at an unknown stage of the oestrous cycle, were ...
