Short description:
Physiologically, after the period of optimal fertility (at age 18–31 years), oocyte quality decreases in parallel with the progressive reduction in number of follicles, and this deterioration accelerates after 37–38 years of age (Faddy, 2000, Faddy et al, 1992 and Gougeon, 1996). It has been estimated that, in the general population, about 10% of women younger than 40 years have a premature reduction in the number of ovarian follicles ( Nikolaou, Templeton, 2003 and van Noord et al, 1997).

Several possible causes for diminished ovarian reserve have been identified, and include inherited chromosomal (De Vos et al, 2010 and Gleicher et al, 2009) and genetic disorders (e.g. Fragile-X and galactosaemia) (te Velde and Pearson, 2002) and iatrogenic causes (Treloar, 1981 and Ferraretti et al, 2011); however, most cases of premature ovarian insufficiency are still unexplained (Nikolaou and Templeton, 2003).

Abstract:
Poor responders represent a significant percentage of couples treated in IVF units (10-24%), but the standard definition of poor responders remains uncertain and consequently optimal treatment options remain subjective and not evidence-based. In an attempt to provide uniformity on the definition, diagnosis and treatment of poor responders, a worldwide survey was conducted asking IVF professionals a set of questions on this complex topic. The survey was posted on www.IVF-worldwide.com, the largest and most comprehensive IVF-focused website for physicians and embryologists. A total of 196 centres replied, forming a panel of IVF units with a median of 400 cycles per year. The present study shows that the definition of poor responders is still subjective, and many practices do not use evidence-based treatment for this category of patients. Our hope is that by leveraging the great potential of the internet, future studies may provide immediate large-scale sampling to standardize both poor responder definition and treatment options.
