The document discusses management strategies for poor responders undergoing assisted reproductive technology. It begins by defining poor responders according to the Bologna criteria and shows how live birth rates decrease significantly with fewer oocytes retrieved. It then outlines an approach to managing poor responders that includes identifying at-risk patients using biomarkers like AMH, individualizing controlled ovarian stimulation protocols, optimizing lab procedures, and tailoring embryo transfer. Specific strategies discussed include using gonadotropins like recombinant FSH, adding LH supplementation, antagonist protocols, and minimal stimulation approaches.

Identifying Patients at Risk
Biomarkers such as AMH and AFC helpful to
identify “expected” poor responders
Similar accuracy to determine who is at risk of POR
Clinical utility need to be validated with own data
Opportunity to offer an individualized COS

phenotype, biomarkers and stimulation protocol

21. Rationale of LH supplementation
Action of LH at the follicular level
in a dose dependent manner
increases androgen production
Androgens are then aromatized to
estrogens and help restore the
follicular milieu
Action of LH at the GC level enhance
responsiveness to FSH
LH has also a direct positive effect on
final oocyte maturation
