BACKGROUND: folliculogenesis is a strictly regulated process that may be affected by endocrine disrupting chemicals (EDCs) through sometimes not so clear molecular mechanisms. METHODS: we conducted a multicentric observational study involv…
PURPOSE: The aim of the present study was to evaluate whether in a modified natural cycle (modified-NC) for a frozen-thawed single euploid blastocyst transfer, a critical LH value, above which human chorionic gonadotropin (hCG) administrati…
PURPOSE: The aim of the study was to evaluate two methods of endometrial preparation for frozen-thawed single euploid blastocyst transfer: modified natural and artificial cycle with GnRH-agonist pituitary suppression. METHODS: In this pros…
PURPOSE: The aim of the present randomized, comparative study was to evaluate the effect of reduced culture volumes on sibling human embryo development. METHODS: Firstly, sibling injected oocytes obtained from 88 out of 165 consenting coup…
The aim of this study is to determine if the use of preimplantation genetic screening (PGS) by array comparative genomic hybridization (array CGH) and transfer of a single euploid blastocyst in patients with repeated implantation failure (R…
PURPOSE: To evaluate the role of co-transfer of embryos derived from vitrified oocytes accumulated during the previous modified natural cycles and an embryo developed from the last one as an alternative to repetitive single embryo transfer …
371 L’endometriosi rappresenta il 5-7% delle cause femminili di infertilita di coppia ed e presente nel 25-40% delle donne infertili, rispetto al 5-10% della popolazione generale (Verkauf, 1987; Berube et al., 1998). I meccanismi con i qual…
