PURPOSE: To evaluate whether the outcomes and characteristics of a first IVF/ICSI cycle are associated with embryological and clinical outcomes in a subsequent cycle performed within 2 years. METHODS: This retrospective single-center obser…
PURPOSE: To evaluate whether artificial endometrial preparation using hormone replacement therapy (HRT) influences clinical and neonatal outcomes compared with modified natural cycles (mNC) in single euploid vitrified-warmed blastocyst tran…
PURPOSE: To identify treatment-related factors influencing low oocyte maturation rates in standard ovarian stimulation (OS) cycles and patients' candidates for clinical studies on rescue-IVM. METHODS: Retrospective study including retrieva…
AIMS: To evaluate DuoStim strategy across a decade from its clinical implementation in IVF by comparing embryological and clinical outcomes between the first and second ovarian stimulations (1st-OS and 2nd-OS) conducted within 30 days, focu…
PURPOSE: This study is to evaluate the effectiveness of a PPOS protocol in poor prognosis patients undergoing IVF with DuoStim and PGT-A versus the conventional protocol with GnRH antagonist. METHODS: Retrospective cohort study encompassin…
PURPOSE: To evaluate the performance of different embryo transfer (ET) operators in a strictly controlled scenario minimizing potential confounders. METHODS: This single-center retrospective cohort study analyzed vitrified-warmed single eu…
OBJECTIVE: To examine the association between semen parameters, assessed according to World Health Organization (WHO)-2021 criteria, and paternal body mass index (BMI) and age, with embryological and clinical outcomes in ICSI cycles involvi…
BACKGROUND: Folliculogenesis occurs in the highly dynamic environment of the ovary. Follicle cyclic recruitment, neo-angiogenesis, spatial displacement, follicle atresia and ovulation stand out as major events resulting from the interplay b…
PURPOSE: An impact of different gonadotrophins selection for ovarian stimulation (OS) on oocyte competence has yet to be defined. In this study, we asked whether an association exists between OS protocol and euploid blastocyst rate (EBR) pe…
Angiogenesis is a host-mediated mechanism in disease pathophysiology. The vascular endothelial growth factor (VEGF) pathway is a major determinant of angiogenesis, and a comprehensive annotation of the functional variation in this pathway i…
A 43-year-old multiparous woman with a history of pelvic endometriosis and myocardial infarction presented with acute onset of right hemithorax pain and dyspnoea coinciding with dysmenorrhoeic menstruation. A chest CT confirmed the presence…
Routine neonatal circumcision—the non-therapeutic circumcision of infant males—has generated considerable ethical controversy. In this article, I suggest that much of the disagreement results from conflicting ideas about the autonomy of the…
