DOES THE PGTA SHORTEN THE TIME TO PREGNANCY IN AN EGG DONATION PROGRAM?

To determine whether PGTa shortens the time to pregnancy or number of embryo transfer in an egg donation program. This was a single-center retrospective study. Of total patients who underwent oocyte at Cegyr between 2016 and 2019 (1181 recipients), 234 recipients were included. All included performed frozen-thawed single transfer, achieving live birth some transfers performed. these, 68 PGT-A (group A) 166 did not perform B). results takes 1 month. Those never (28), get pregnant (470), received less than 10 MII (270) fresh (179) excluded. Static analysis with t-student test. In group A, average age 42 (32-50 years old), oocytes allocated 13.93, blastocysts per patient 5.88 blastulation rate 57%. B, (30-49 11.45, 4.81 58%. The months achieve from moment allocation five half (M=5.57; SD=0.42) A four (M=4.58; SD=0.17) this difference significant; t (1.29), p>0.05. 4 B 5. until obtained 1.6 (M=1.58; SD=0.01) versus 1.73 (M=1.73; (1.27), Although is tool select euploid embryos, thus seek shorten necessary it, case program, we find such benefit for either two parameters analyzed. main limitation study its design based on data center which may be subject bias. Further large prospective studies are required make meaningful comparisons.
