Infertility, diminished ovarian reserve.

The aim of the study is to examine the effects of low dose hCG priming for eight weeks in women with DOR undergoing IVF/ICSI. We want to retest the findings of our pilot study (Friis Wang et al. 2023), as an increase of 50% in number of oocytes retrieved is clinically relevant.
