Konstantinos Ravanos,Themistoklis Dagklis,Stamatios Petousis,Chrysoula Margioula-Siarkou,Yannis Prapas,Nikolaos Prapas +5 more
TL;DR: A review of several factors considered to be implicated in the initiation of human parturition, which suggests that spontaneous preterm and term labor seem to share a common inflammatory pathway.
Journal ArticleDOI
Anatomic distribution of endometriosis: A reappraisal based on series of 1101 patients.
A Audebert,Stamatios Petousis,Chrysoula Margioula-Siarkou,Konstantinos Ravanos,Nikolaos Prapas,Yannis Prapas +5 more
TL;DR: Ovary was the main site of endometriotic lesions followed by the utero sacral ligaments, and left side was predominant for all locations except for ovarian SI and fallopian tube.
Journal ArticleDOI
History of endometriosis may adversely affect the outcome in menopausal recipients of sibling oocytes.
Yannis Prapas,Maria Goudakou,Ioannis Matalliotakis,Alexandra Kalogeraki,Charikleia Matalliotaki,Yannis Panagiotidis,Konstantinos Ravanos,Nikos Prapas +7 more
TL;DR: The oocyte donation model was used in an attempt to understand whether the endometrium, the oocytes or both are affected by endometriosis, and the pregnancy and implantation rates were significantly lower in the endometricriosis group compared to the control group.
Journal ArticleDOI
GnRH antagonist administered twice the day before hCG trigger combined with a step-down protocol may prevent OHSS in IVF/ICSI antagonist cycles at risk for OHSS without affecting the reproductive outcomes: a prospective randomized control trial
