Frozen-thawed embryo transfer has been associated with a significantly lower risk of ectopic pregnancy (EP) compared with fresh cycles. Ovarian stimulation might be associated with an increased risk of EP.
Female cystic fibrosis (CF) carrier status does not appear to impact the chance of achieving pregnancy with assisted reproductive technology (ART). Further research is needed to investigate whether positive CF carrier status affects fertility in a non-ART context.
Our data demonstrated no difference in euploid blastocyst rates between presumed fertile and infertile patients. Pregnancy and implantation rates were significantly higher in presumed fertile patients when transferring euploid blastocysts.
This study investigated the prevalence and significance of reverse cleavage by human embryos observed via time-lapse monitoring. Embryos showing reverse cleavage were associated with compromised subsequent development and implantation potential.
An alternative strategy for embryo selection based on a multivariable morphokinetic model combined with continuous incubation in an integrated timelapse monitoring system improves the clinical results.
Diagnostic testis biopsy in nonobstructive azoospermia has little value, even when uniform Sertoli cell–only pattern is seen. When both testis volume and follicle-stimulating hormone are considered, sperm retrieval rates are 7%–45%.
Palmitoylethanolamide and oleoylethanolamide in human seminal plasma may preserve sperm functions and disturbances in their normal functioning by exocannabinoids found in Cannabis, could result in male reproductive failure.
Controlled ovarian hyperstimulation (COH) is considered a key factor in the success of IVF-ET because it enables the recruitment of multiple healthy fertilizable oocytes and, thereby, multiple as opposed to single ET. COH usually includes the coadministration of gonadotropins and GnRH analogues; the two most commonly used protocols are the long GnRH agonist suppressive protocol and the multiple-dose GnRH antagonist COH protocol.
An international collaboration of endometriosis research and biobanking experts developed standard operating procedures for the collection, processing, and storage of biological tissue samples in endometriosis and control subjects to allow large-scale collaborative research.
