8. Key Points (1)
There is a strong association between the
number of oocytes retrieved and live birth
rates in IVF
The optimum number of oocytes needed to
maximize IVF outcomes seems to be about 15
COS should be tailored to the individual
phenotype, maximizing the number of oocyte
yield for poor responders and fine-tuning for
hyper-responders

The number of oocytes obtained is a key factor
for optimizing Live Birth rates
COS should be tailored to the individual phenotype,
maximizing the number of oocyte yield for poor
responders and fine-tuning for hyper-responders
COS with recombinant FSH results in an
increased oocyte yield compared with hMG/uFSH
Higher FSH bioactivity, which is related to the way the
drug is made, filled and delivered

54. Conclusions (2)
AMH and AFC are currently the best tools to
