“…Pregnancy rates were given as per cycle commenced and per embryo transfer attempt. We calculated the implantation rate for a given patient (individual implantation rate) by dividing the number of sacs with fetal cardiac activity by the number of embryos transferred, as reported (Ben-Shlomo et al, 1997). We then summed the individual implantation rates and divided by the number of embryo transfer attempts in each group.…”

The European Society of Human Reproduction and Embryology published Bologna criteria to generate a definition of poor ovarian responders (PORs). However, there are few data on whether PORs are homogenous for ovarian response or live birth rates (LBRs). In this retrospective study, 821 patients fulfilling Bologna criteria and undergoing intracytoplasmic sperm injection were stratified into four groups: Group A: female age ≥40 with a previous poor response (cycle cancelled or ≤3 oocytes) (105 patients, 123 cycles); Group B: female age ≥40 with an antral follicle count (AFC) < 7 (159 patients, 253 cycles); Group C: AFC <7 with a previous poor response (350 patients, 575 cycles); and Group D: female age ≥40 with an AFC <7 and previous poor response (207 patients, 306 cycles). Cluster data analysis was performed. Although median number of oocytes was higher in Group B (P < 0.001), higher implantation (P = 0.024) and LBR per embryo transfer (P < 0.001) or cycle (P = 0.001) were noted in Group C. We conclude that, once a patient fulfils Bologna criteria, prognosis is poor, with fewer than 10% recorded LBRs per cycle. However, the LBRs are not homogenous and 'young proven' PORs have the most favourable pregnancy outcome.

“…• Female <35 years, with bilateral tubal occlusion and regular menstrual cycles • No previous pregnancy in the couple • Normal serum FSH in female • Normal-sperm count in male • Only the first two cycles reaching oocyte pickup (without the first cycle resulting in a pregnancy) • Frozen embryo pregnancy additions to be included (with a 5-year limit) • Implantation rate (rather than pregnancy rate) defined as "number of positive hearts or fetal sacs seen on ultrasound per embryo transferred," expressed as a percentage (6). We put this standard forward and invite comments.…”
