Summary.

The primary sex-ratio of the PDE mouse, assessed by chromosomal analysis of embryos recovered after superovulation, was not significantly different from 100, nor was it significantly affected by delayed fertilization. The sex-ratio was assessed after implantation and at full term. There was no evidence of sex-selective mortality operating at any stage of gestation.
