First case report of a successful delivery of a healthy boy by preimplantation genetic testing for Beckwith-Wiedemann syndrome.

Purpose: To showcase the successful use of ICSI with PGT-M to overcome Beckwith-Wiedemann syndrome (BWS)-related reproductive challenges, resulting in the birth of a healthy baby boy. By targeting the maternally inherited CDKN1C pathogenic gene variant, this report highlights the genetic interventions in BWS reproductive risk management.

Methods: This case report describes a 41-year-old woman seeking fertility assistance after a previous pregnancy revealed a fetal anomaly related to BWS.

Sperm Preparation with Microfluidic Sperm Sorting Chip May Improve Intracytoplasmic Sperm Injection Outcomes Compared to Density Gradient Centrifugation.

Does sperm preparation using the FERTILE PLUS™ Sperm Sorting Chip improve fertilization rates, blastocyst formation, utilization, and euploidy rates in patients undergoing intracytoplasmic sperm injection (ICSI), compared with density gradient centrifugation (DGC)? A single-cohort, retrospective data review including data from 53 couples who underwent ICSI cycles within a 12-month period. For each couple, the two closest, consecutive cycles were identified, where one used the standard technique of sperm preparation (DGC) and the subsequent used FERTILE PLUS™, therefore, couples acted as their own controls. Paired samples t-test was used to compare means for the outcomes (fertilization, blastocyst formation, utilization, and euploidy rates).

Complex chromosomal aberrations in a fetus originating from oocytes with smooth endoplasmic reticulum (SER) aggregates.

Unlabelled: The presence of smooth endoplasmic reticulum aggregates (SERa) in the ooplasm is considered as the most severe oocyte dysmorphism due to its serious and potentially lethal outcomes in offspring. In the present case report, a couple underwent their first intracytoplasmic sperm injection (ICSI) cycle using a gonadotrophin releasing hormone (GnRH) antagonist protocol, followed by fetal ultrasound scanning and amniocentesis. SERa were observed in all oocytes retrieved.
