Perinatal blockade of neuronal glutamine uptake by MeAIB (5 mm, icv) administered for 1 day on either PN0 or PN5 (or PN6) had no effect on the expression of mating behavior in male rats

There were no significant differences in the effects of MeAIB on the two age groups.
icv, intracerebroventricular injection; DW, distilled water; PN, postnatal day.
The numbers in parentheses indicate the number of animals tested.
p = 0.97, p = 0.93, p = 0.74, p = 0.46, and p = 0.38 for total number of mounts, intromissions, ejaculation, latency to mount, and latency to intromission, respectively; two-way ANOVA (age × pretreatment).
