ABSTRACT
Objective: To evaluate results of a combined approach in IVF, using minimal stimulation,
preimplantation genetic testing for aneuploidy, and single blastocyst transfer.
Materials and Methods: Retrospective cohort study over a three years’ period
in two fertility centers in Mexico. A total of 125 patients were included, between 25
and 45 years old, with minimal stimulation IVF, preimplantation genetic testing for
aneuploidy (PGT-A) and single euploid embryo transfer. PGT was performed using
microarrays and next generation sequencing (NGS).
Results: A total of 175 cycles (mean age: 39 years old) were analyzed in 125 patients.
On average, five eggs were collected per cycle; fertilization rate was 86.57%; blastocyst
rate was 50.7% per fertilized egg. Only 33% of embryos were euploid. Pregnancy rate
per transferred embryo was 71%. Live birth rate was 60.8% (42 births).
Conclusions: A combination of minimal stimulation, PGT-A and single blastocyst
embryo transfer can yield a high live birth rate.
