To evaluate the impact of embryo quality and quantity, specifically a poor quality embryo (PQE) in combination with a good quality embryo (GQE), by double embryo transfer (DET) on the live birth rate (LBR) and neonatal outcomes in patients undergoing frozen-thawed embryo transfer (FET) cycles...
Are obstetrical outcomes after IVF with PGT-A more strongly correlated with embryo grading prior to biopsy or dayof thaw for embryo transfer?doi:10.1016/j.fertnstert.2019.02.110Monica C. Pasternak MDMichaela Thompson BASteven Spandorfer MD
The survivability and clinical outcome of the two respective vitrification kits was compared between the age group, blastocyst grading prior to freezing (Good, Fair, Poor) and the day of blastocyst freezing (D5 or D6). MAIN RESULTS AND THE ROLE OF CHANCE. The overall mean post thawed ...
Blastocysts were assessed on the basis of the criteria of the Gardner and Schoolcraft grading system (36) and considered for cryopreservation on day 5 or 6 if the embryo grade was ≥3 BC. Good-quality blastocysts were defined if they reached at least expansion stage 3 with classification as ...
According to the embryo score group, the group with higher scores did not show distinct better FHB+ rates (KIDScore: 65% vs. 69.51% vs. 47.6% vs. 0%; iDAScore: 64.1% vs. 67.7% vs. 38.8% vs. 0%). The PGT-A results indicated that morphological grading could be given high priority...
PGT-ALive birth rateTo determine whether embryo developmental stage or morphological grading can predict live birth rate (LBR) from a single blastocyst in nonbiopsied and biopsied frozen embryo transfer (FET) cycles. This retrospective study included 1336 nonbiopsied and 360 euploid FET cycles. ...
Interobserver variation was controlled for by establishing annotation guidelines and through regular review of grading among embryologists. Blastocyst grade was assigned based on blastocyst maturity, inner cell mass development, and trophectoderm organization, using the European Society of Human Reproduction...
4.2. Controlled Ovarian Stimulation, In Vitro Fertilization, Embryo Culture and Grading All patients were treated with a GnRH antagonist protocol as previously descrived [31]. Oocyte collection was performed 36 h after triggering of ovulation. In both groups, in order to avoid biases in the ...
