Long-term Endogenous Androgen Priming in Bologna Criteria Poor Responder Patients - A Pilot Study

"Androgen priming: with a low dose of recombinant hCG, aromatase inhibitor, and a depot GnRHa for 8 weeks Stimulation: a standard rFSH stimulation with either 300 IU rFSH or 300 IU (rFSH + rLH) Blood sampling: 6 blood samples to measure FSH, LH, E2, testosterone, and AMH Ultrasound examination: to count all antral follicles, 2-10 mm in each ovary Follicular fluid: to analyze E2, androstenedione, testosterone, progesterone, inhibin B.~Granulosa cells: to analyze gene expression in cumulus and mural granulosa cells of Luteinising hormone receptor (LHR), 3β-hydroxy-steroid-dehydrogenase (3ßHSD), inhibin-Ba (INHB-A) receptor, androgen and FSH receptor"
