for ART
Pharmaceutical industry
One size fits all protocol for OS
suppress LH surge: GnRHa
ovarian stimulation with HMG/FSH
high doses of gonadotropin
high number oocytes
high number of embryos
Results not the same for all
poor response and OHSS
side effects
patient satisfaction neglected
8. Ovulation Induction
One size fits all?
Patient is the main
variable of OI response
Demographics and
anthropometrics (Age,
BMI, Race)
Genetics profile
Cause of Infertility
Years of Infertility
Health status
Nutritional status
9. What we really want to know in OI is...
How to define the right individual
treatment for the right patient to:
●Prevent poor response and
OHSS (reduce cancellation)
●Reduce side effects
●Increase pregnancy rates
●Reduce physical, psychological
and financial burden
Esteves, 9
10. Understanding the Problem
From cookery to science
Individualizing ovarian
stimulation according to
patients is important
But how ?
There are several predictors
of ovarian response
Can we make prediction
more scientific but simple ?
Esteves, 10
12. Markers of Ovarian Response
Can we predict ovarian response?
Age
Biomarkers
● Hormonal Biomarkers, FSH, Inhibin-B, AMH
● Functional Biomarkers: Antral Follicle Count (AFC)
● Genetic Biomarkers: Single Nucleotide Polymorphisms for
FSH-R/LH/LH-R/E2-R/AMH-R

The majority of patients do not need LH
supplementation as endogenous LH levels are

Older patients (> 35 years)4
Low responders5
Deeply suppressed endogenous LH6
Hypo-responders7
