“…In the course of analysing the studies that are consistent with the deleterious effect of female age, it was verified once again that increasing female age decreased the mean number of retrieved oocytes (Pinto et al, 2009;Maman et al, 2012;Ramezanzadeh et al, 2012;O'Brien et al, 2017;Sahin et al, 2021), embryo quality (Ramezanzadeh et al, 2012;Bocca et al, 2017), embryo cleavage rate (Ramezanzadeh et al, 2012), FR (O'Brien et al, 2017, biochemical pregnancy rate (BPR) (O'Brien et al, 2017), CPR (Kovacs et al, 2003;Shen et al, 2003;Pinto et al, 2009;Huang et al, 2012;Maman et al, 2012;Berger et al, 2014;Coelho Neto et al, 2015;Nouri et al, 2015;Meijerink et al, 2016;Amsiejiene et al, 2017;Bocca et al, 2017;Hassan et al, 2017;O'Brien et al, 2017;McPherson et al, 2018;Peuranpää et al, 2020) and LBR (Nelson & Lawlor, 2011;Hamdine et al, 2015;Nouri et al, 2015;McPherson et al, 2018;Peuranpää et al, 2020;Wen et al, 2021), and was associated to poor response cycles (Maman et al, 2012), higher cancellation rate (Borges et al, 2017), higher miscarriage rate (Peuranpää et al, 2020;Sahin et al, 2021) and higher risk of macrosomia (Nelson & Lawlor, 2011). On the other hand, other studies showed no or mixed outcomes with female age such as ...…”
