- Spritzer M, Curtis M, DeLoach J, Maher J, Shulman L. Sexual interactions with unfamiliar females reduce hippocampal neurogenesis among adult male rats. Neuroscience. 2016;318:143-56 pubmed publisher..In combination, these results indicate that interactions with unfamiliar females reduce adult neurogenesis and the effect is stronger for sexual interactions than for social interactions. ..
- Wagner B, Braddick V, Batson C, Cullen B, Miller L, Spritzer M. Effects of testosterone dose on spatial memory among castrated adult male rats. Psychoneuroendocrinology. 2017;89:120-130 pubmed publisher..Testosterone replacement restored spatial memory among castrated male rats on both behavioral tasks, but there was a complex dose-response relationship; therefore, the therapeutic value of testosterone is likely sensitive to dose. ..
- Spritzer M, Ibler E, Inglis W, Curtis M. Testosterone and social isolation influence adult neurogenesis in the dentate gyrus of male rats. Neuroscience. 2011;195:180-90 pubmed publisher..This suggests that normal circulating levels of testosterone may buffer against the neurogenesis-impairing effects of isolation, whereas high doses of testosterone do not. ..

Seasonal and sex differences in cell proliferation, neurogenesis, and cell death within the dentate gyrus of adult wild-caught meadow voles. Neuroscience. 2017;360:155-165 pubmed publisher..Overall, these results suggest higher levels of neuronal turn-over during the non-breeding season relative to the breeding season, possibly due to seasonal changes in sex steroids. ..
