החזרה ו3 בלסטו קפואים ועובד של יום 3

Blastocyst development and stage status 1 Blastocoel cavity less than half the volume of the embryo 2 Blastocoel cavity more than half the volume of the embryo 3 Full blastocyst, cavity completely filling the embryo 4 Expanded blastocyst, cavity larger than the embryo, with thinning of the shell 5 Hatching out of the shell 6 Hatched out of the shell ICM grade Inner cell mass quality A Many cells, tightly packed B Several cells, loosely grouped C Very few cells TE grade Trophectoderm quality A Many cells, forming a cohesive layer B Few cells, forming a loose epithelium C Very few large cells Blastocysts are given a quality grade for each of the 3 components and the score is expressed with the expansion grade listed first, the inner cell mass grade listed second and the trophectoderm grade third. For example, a blastocyst quality grade of 4AB means that the blastocyst is expanded (grade 4), has many tightly packed cells in the inner cell mass (grade A), and has a trophectoderm with few cells forming a loose epithelium (grade B). See the examples of blastocyst grading pictures below.

להלן שיטת הדירוג באנגלית -המשתניםשל הדרוג לוקחים בחשבון מספר משתנים: 1.מידת ההרחבות של הבלסטוציסט 2.התאים החיצוניים המרכיבים את הטרופקטודרם(השליה(העתידית) 3.ומסת התאים הפנימיים שירכיבו את העובר להלן שיטת גרדנר לדרוג בלסטוציסטים The Gardner blastocyst grading system assigns 3 separate quality scores to each blastocyst embryo: Blastocyst development stage - expansion and hatching status Inner cell mass (ICM) score, or quality Trophectoderm (TE) score, or quality Expansion grade Blastocyst development and stage status 1 Blastocoel cavity less than half the volume of the embryo 2 Blastocoel cavity more than half the volume of the embryo 3 Full blastocyst, cavity completely filling the embryo 4 Expanded blastocyst, cavity larger than the embryo, with thinning of the shell 5 Hatching out of the shell 6 Hatched out of the shell ICM grade Inner cell mass quality A Many cells, tightly packed B Several cells, loosely grouped C Very few cells TE grade Trophectoderm quality A Many cells, forming a cohesive layer B Few cells, forming a loose epithelium C Very few large cells Blastocysts are given a quality grade for each of the 3 components and the score is expressed with the expansion grade listed first, the inner cell mass grade listed second and the trophectoderm grade third.
