Also, it has been hypothesized that disturbed Zr-protein
synthesis in females may give oocytes with abnormal
eggshells, resulting in lower egg quality or problems with
hatching and survival (Arukwe and Goksùyr, 1998).
In accordance with these changes, it is to be expected
that testicular development will slow down as has been
reported by Jobling et al. (1996) and Harries et al.
(1997).
