Thus there was some evidence that irradiated PRD diet has weak mutagenic activity in the meiotic and/or pre-meiotic phase of the spermatogenic cycle which appeared to be lessened on storage; the inclusion of such a diet in toxicological studies would therefore need to be carefully considered.

Transient exposure of a gestating female rat during the period of gonadal sex determination to the endocrine disruptors vinclozalin (an antiandrogenic compound) or methoxychlor (an estrogenic compound) induces decreased spermatogenic capacity (cell number and viability) and increased incidence of male infertility in nearly all males of all subsequent generations examined.

"It is the males that invest most effort into extravagant sexual display that experience this spermatogenic 'burn-out' at an earlier age," the researchers, led by biologist Brian Preston, wrote in this week's Ecology Letters journal - according to Wired, since I don't have a subscription.

Seminiferous tubules showed disruption of the normal spermatogenic cycle with abnormal acrosomal development on round spermatids, clumping of acrosomes, misaligned spermatids and the absence of normal elongated spermatids in Ehd1 -/- males.
