Dimitraki, M.; Messini, C. I.; Dafopoulos, K.; Gioka, T.; Koutlaki, N.; Garas, A.; Georgoulias, P.; Messinis, I. E. (2014)Objective Oestradiol sensitizes the pituitary to GnRH, while gonadotrophin surge attenuating factor (GnSAF) may oppose this action.

Messini, C. I.; Dafopoulos, K.; Chalvatzas, N.; Georgoulias, P.; Anifandis, G.; Messinis, I. E. (2011)Background: Administration of ghrelin to women stimulates the secretion of PRL but the mechanism is not known. Aim: The aim of the study was to investigate the effect of the dopamine receptor blocker, metoclopramide, on ... -
Effect of Ghrelin and Thyrotropin-releasing Hormone on Prolactin Secretion in Normal Women
Messini, C. I.; Dafopoulos, K.; Chalvatzas, N.; Georgoulias, P.; Anifandis, G.; Messinis, I. E. (2010)It is known that ghrelin stimulates the secretion of prolactin in women. The aim of this study was to examine the effect of exogenous thyrotropin-releasing hormone (TRH) on ghrelin-induced prolactin release. Ten healthy ... -
Effect of ghrelin on gonadotrophin secretion in women during the menstrual cycle
Messini, C. I.; Dafopoulos, K.; Chalvatzas, N.; Georgoulias, P.; Messinis, I. E. (2009)It has been suggested that ghrelin may affect reproduction in animals by decreasing pituitary LH secretion. The role of ghrelin on LH secretion in women has not been investigated. Our aim was to assess the effect of ghrelin ... -
Effect of the Position of the Polar Body During ICSI on Fertilization Rate and Embryo Development
Anifandis, G.; Dafopoulos, K.; Messini, C. I.; Chalvatzas, N.; Messinis, I. E. (2010)This prospective study was designed to evaluate and clarify further whether the position of the polar body (PB) in relation to injection site during intracytoplasmatic sperm injection (ICSI) has an impact on fertilization ... -
Elimination Half-Life of Anti-Mullerian Hormone
Griesinger, G.; Dafopoulos, K.; Buendgen, N.; Cascorbi, I.; Georgoulias, P.; Zavos, A.; Messini, C. I.; Messinis, I. E.
