Morphokinetic parameters in chromosomal translocation carriers undergoing preimplantation genetic testing
Can embryo morphokinetic parameters help identify unbalanced embryos in translocation carriers?Proficiency in oocyte retrieval assessed by the learning curve cumulative summation test
The number of procedures required for a trainee to reach proficiency in oocyte retrieval and the criteria applied to define performance are not well defined. To evaluate the learning curve of oocyte retrieval, this study prospectively evaluated three trainees over 6 months. Oocyte retrieval was monitored by the learning curve–cumulative summation test (LC-CUSUM), a specific statistical tool designed to indicate when a predefined level of performance is reached. Oocytes were retrieved from one ovary by the trainee and from the second ovary by a senior operator in a randomized manner.
