hMG and rec-hFSH
q Lower expression of LH/hCG receptor
gene and other genes involved in
steroids biosynthesis in hMG group
Down-regulation of receptors owed to
constant ligand exposure to hCG
(Menon et al. 2004)
CYP11A activity decreased by 2.4 fold
Lower steroids synthesis and P levels
q Higher potency of rec-hFSH inducing
more LH/hCG receptors

33. Take Home Messages
AMH and AFC are currently the best biomarkers
to predict ovarian response to COS.
AMH and AFC are direct biomarkers of ovarian
reserve. Both markers have similar accuracy to
predict who is at risk of excessive and poor
response in COS.
After identifying ‘Who is Who’, mild stimulation and
GnRH antagonists in pts. at risk of excessive
response, and rec-hLH supplementation in DOR,
are useful strategies to optimize outcomes in ART
cycles.
