Seasonal changes in the prostatic complex of Artibeus planirostris (Chiroptera: Phyllostomidae)

Seasonal changes in the prostatic complex of Artibeus planirostris (Chiroptera: Phyllostomidae)

Highlights • We analyzed morphologically annual variations in the prostate of a neotropical bat. • The prostate showed marked variations throughout the year. • Increasing of circulating testosterone increased the prostate and testicular weight. • Two regions of prostate responded differently to vari...

Zusammenfassung:Highlights • We analyzed morphologically annual variations in the prostate of a neotropical bat. • The prostate showed marked variations throughout the year. • Increasing of circulating testosterone increased the prostate and testicular weight. • Two regions of prostate responded differently to variations in testosterone. • Testosterone stimulates the prostate to prepare for the two reproductive periods.
