Accuracy of preimplantation genetic screening (PGS) is compromised by degree of mosaicism of human embryos

Background To preclude transfer of aneuploid embryos, current preimplantation genetic screening (PGS) usually involves one trophectoderm biopsy at blastocyst stage, assumed to represent embryo ploidy. Whether one such biopsy can correctly assess embryo ploidy has recently, however, been questioned. Methods This descriptive study investigated accuracy of PGS in two ways. Part I...

Bye‐bye urinary gonadotrophins?: Recombinant FSH: A real progress in ovulation induction and IVF?*

Whether recombinant gonadotrophin products do, indeed, represent progress for routine ovulation induction and IVF cycles, in comparison with urinary products, has remained controversial. Here we review published data with regard to respective risks, outcomes and cost for both medication options. Safety considerations favour recombinant products, while overall outcome and cost...

The immunological `Wars of the Roses': disagreements amongst reproductive immunologists

The relevance of abnormal autoimmune function to reproductive function in the female has over recent years become an increasingly controversial and contentious issue. Opposing views have led to a polarization of opinions which, at times, resulted in publications of rather vocal opinions by individuals as well as societal committees. This communication is an attempt to reconcile...

The value of intra-operative cystoscopy at the time of laparoscopic hysterectomy

The aim of this study was to determine the usefulness of routine intra-operative cystoscopy in documenting ureteral injury during total laparoscopic hysterectomy with vault suspension and to document the incidence of this complication in a large series. The charts of 118 patients who underwent laparoscopic hysterectomy with vault suspension from January 1992 to January 1998 were...
