Young Low Responders Protected from Untoward Effects of Reduced Ovarian Response

Day-5 inhibin B serum concentrations and antral follicle count as predictors of ovarian response and live birth in assisted reproduction cycles stimulated with gonadotropin after pituitary suppression

“…Thus, the collection of <4 oocytes at retrieval or cancellation of the cycle due to insufficient follicular growth (<3 developing follicles in response to exogenous gonadotropins), as in our investigation, is the most widely used definition of poor response, and it has been used in many other studies because of the poor prognosis in such cases (24)(25)(26)(27)(28)(29)(30)(31).…”

Natural-cycle in vitro fertilization in poor responder patients: a survey of 500 consecutive cycles

“…Although there is no general agreement on this definition, in general poor responder women are the patients who, during controlled ovarian hyperstimulation (COH) for IVF, show poor follicle recruitment despite the high dose of gonadotropins administered, and low levels of serum estradiol peak (12). The incidence of poor responder patients is estimated to be approximately 10% (13).…”

The three-dimensional ultrasonographic ovarian vascularity of women developing poor ovarian response during assisted reproduction treatment and its predictive value

“…Advanced female age is arguably the most important predictor (3), but many young women also respond poorly to ovarian stimulation (4), and this may relate to environmental factors such as smoking or reflect ovarian damage following surgical intervention or pathophsiologic processes such as ovarian endometriosis and pelvic infection (5). These factors influence ovarian response, as they affect either the size of the recruitable follicle population or the sensitivity of these follicles to gonadotrophins (6).…”
