While middle aged infertility patients in section (iii) of this study and presumed fertile women in section (ii) present with quite similar genotype/sub-genotype distribution, older infertile women in section (i), with mean age 39.7±5.7 years, demonstrated approximately 20 percentage points lower norm FMR1 genotype prevalence (41.1%) and a much higher prevalence in het-norm/low sub-genotype (30.1%. Here, FMR1 is linked to Infertility.
