Workshop on Management of poor prognosis patientsMatheus Roque
In this presentation, it was discussed new concepts in stratification of low prognosis patients. It was also discussed the differences between LH and hCG, and how they can have an influence during COS.
PPT-Embryo grading and ART Summary.pptxKajal530634
Embryo grading is important in IVF to select good quality embryos for transfer based on developmental rate and morphology. The most followed grading systems are Gardner and Istanbul consensus, which assess embryos daily from fertilization to blastocyst stage based on criteria like cell number, size, and fragmentation. Good quality embryos with early cleavage and cell number on day 2 often develop into good blastocysts. Donor oocyte and sperm criteria and screening are also outlined to follow regulations. Oocyte donors can donate up to 7 oocytes only once in their lifetime from age 23-35.
This document discusses methods for scoring embryos at different stages of development during in vitro fertilization (IVF). It describes parameters evaluated for pronuclear zygotes, cleaved embryos on days 2-3 of development, and blastocysts on days 4-5. Parameters include pronuclear morphology, blastomere number and symmetry, fragmentation, compaction and expansion. Scoring systems assign quality grades based on these parameters to select the most developmentally advanced embryo for transfer. Precise embryo examination and selection of the highest quality embryo can reduce multiple pregnancies resulting from IVF.
