<unk>  is a condition of low fertility characterized by 1): low numbers of remaining oocytes in the ovaries or 2) possibly impaired preantral oocyte development or recruitment. Recent research suggests that premature<unk>  aging and premature<unk>  failure (aka primary<unk>  insufficiency) may represent a continuum of premature<unk>  senescence. It is usually accompanied by high FSH (follicle stimulating hormone) levels. Quality of the eggs may also be impaired. However, other studies show no association with elevated FSH levels and genetic quality of embryos after adjusting for age. The decline in quality was age related, not FSH related as the younger women with high day three FSH levels had higher live birth rates than the older women with high FSH. There was no significant difference in genetic embryo quality between same aged women regardless of FSH levels. A 2008 study concluded that diminished<unk>  did not affect the quality of oocytes and any reduction in quality in diminished<unk>  women was age related. One expert concluded: in young women with<unk><unk>  when eggs are obtained they have near normal rates of implantation and pregnancy rates, but they are at high risk for IVF cancellation; if eggs are obtained, pregnancy rates are typically better than in older woman with normal<unk> . However, if the FSH level is extremely elevated these conclusions are likely not applicable.
