Management of patients with an impaired ovarian reserve or poor ovarian response (POR) to exogenous gonadotropin stimulation has challenged reproductive specialists for years. Apart from the limited understanding of its pathophysiology, there is wide heterogeneity in defining POR and overall disappointing outcomes in assisted reproductive technology (ART) cycles.

The 1st POSEIDON’s World Conference dissect the new POSEIDON criteria as a means to improve the management of patients exposed to assisted reproductive technology. The new criteria enable discussion of novel approaches catered specifically to patients with low prognosis during IVF, thereby offering better tools to optimise IVF success rates.

The program engages renowned international experts with vast clinical experience in constantly evolving subjects. The program aims to impart specific knowledge with focus on changing concepts or practices.
