For much of the 20 thcentury the secondary sex ratio (male births/all births) has been declining in many countries [ 16 17 18 ] . It has been speculated that this declining sex ratio is a sentinel indicator of environmental contamination [ 17 ] , although others have argued that, on a population level, this is not the case [ 16 18 19 20 21 ] . There is evidence, however, that hormonal levels around the time of conception are associated with the sex ratio of offspring [ 22 ] , and there is compelling evidence that exposure to particular chemicals does lead to changes in the sex ratio of offspring [ 23 24 25 26 27 ] , as seen, for example, with exposure to dioxins following an explosion at an herbicide plant in Seveso, Italy [ 26 27 ] . Animal studies have suggested that exposure to PCBs may lower the sex ratio of offspring [ 28 29 30 ] . Studies among human populations exposed to PCBs in different settings, however, have suggested increases [ 31 ] , decreases [ 32 33 ] , or no change [ 34 35 ] in the sex ratio.

M6P/IGF2R is normally imprinted in mice with only the maternal copy of the gene being expressed [ 41 ] . In contrast, both copies of the M6P/IGF2R are expressed in humans because genomic imprinting at this locus was lost in the primate lineage approximately 75 million years ago [ 42 ] . Importantly, restoration of biallelic M6P/IGF2R expression in mice results in a marked reduction in offspring weight late in embryonic development that persists into adulthood [ 43 ] . This demonstrates that M6P/IGF2R allelic loss or haploid insufficiency markedly enhances cell proliferation and/or survival during fetal development.
