The effect that gonadotrophin-releasing hormone (GnRH) antagonists exert on endometrial receptivity has not yet been elucidated. GnRH antagonists might directly affect oocytes, the embryo and/or the endometrium. The aim of this study was to investigate the direct effect of GnRH antagonists on the endometrium in oocyte donation cycles. In an oocyte donation(More)
The effect of low-dose human chorionic gonadotropin (hCG) administration in the proliferative phase of oocyte recipients was investigated in a prospective randomized trial. Sibling oocytes from the same donor were shared at random among two different recipients. In group I oocyte recipients received 750 IU of hCG every three days concomitant to endometrial(More)
This pilot study evaluated the possibility of preventing early ovarian hyperstimulation syndrome (OHSS) by increasing the daily dose of gonadotrophin-releasing hormone (GnRH) antagonist administration (to twice a day) in oocyte-donor cycles stimulated with the antagonist protocol. The study included 72 oocyte donors who underwent ovarian stimulation using(More)
OBJECTIVE To investigate whether diamniotic twin gestations are at increased risk of amniocentesis-related adverse outcomes compared to singleton pregnancies. STUDY DESIGN This was a retrospective study of mid-trimester amniocenteses performed during the period 1993-2009. Cases were divided in two groups, one including singleton (Group 1) and the other(More)
OBJECTIVE To examine vertical transmission rates of Cytomegalovirus, Toxoplasma Gondii and Rubella infections according to amniotic fluid PCR analysis. METHODS A retrospective analysis of mid-trimester amniocenteses performed in in pregnancies with diagnosed maternal infection by Cytomegavirus (CMV), Rubella or Toxoplasma gondii during 1994-2008 was(More)
PURPOSE To examine the accuracy of the Fetal Medicine Foundation algorithm used to adjust the risk for trisomy 21 after ultrasound findings detected or not at the time of the anomaly scan. METHODS This was a retrospective study of all amniocenteses performed in a single centre, in singleton pregnancies, between 1998 and 2008. Maternal demographic(More)
