The reproductive accessory glands (RAG) are essential components in reproduction because their secretion products ensure survival, viability, and sperm motility. The objective of this study was to characterize and compare the morphological and histological structure of the RAG in three species of bats of the genus Sturnira (S. erythromos, S. lilium, and S. oporaphilum). The RAG complex comprise a compact gland (prostate), which surrounds the urethra, and a pair of Glands of Cowper at the base of penis. Anatomical and histologically, the prostate are differentiated in two regions, ventral and dorsal. The dorsal region has tubuloalveolar glands with secretions fine granular or accumulations of a gel-like substance with bubbles and the ventral region, has alveolar glands with secretory cells form a single-layer of small cells. The seminal vesicles are absent. The prostatic morphology of the three species is similar to that of other studied Stenodermatinae and Desmodontinae, but differs from other subfamilies of Phyllostomidae (Carollinae, Glossophaginae, and Phyllostominae) as that of Molossidae and Vespertilionidae. The RAG complex has no annual variation in relation to functionality or size, but it is variable depending on age (subadults and adults). This agrees with the annual reproductive pattern described for these species in these latitudes, where adult males are reproductively active throughout the year.
生殖附属腺（RAG）是生殖过程中的重要组成部分，因为其分泌产物能确保精子的存活、活力和运动能力。本研究的目的是对星鼻蝠属（Sturnira）的三种蝙蝠（红鼻星鼻蝠、白喉星鼻蝠和奥氏星鼻蝠）的生殖附属腺的形态和组织结构进行表征和比较。生殖附属腺复合体包括一个围绕尿道的致密腺体（前列腺）以及阴茎基部的一对考珀氏腺。从解剖学和组织学角度来看，前列腺可分为腹侧和背侧两个区域。背侧区域有管泡状腺，其分泌物为细颗粒状或含有气泡的凝胶状物质聚积物，而腹侧区域有泡状腺，其分泌细胞形成单层小细胞。精囊缺失。这三种蝙蝠的前列腺形态与其他已研究的狭面叶口蝠亚科和吸血蝠亚科相似，但与叶口蝠科的其他亚科（卡罗利叶口蝠亚科、长舌叶口蝠亚科和叶口蝠亚科）以及犬吻蝠科和蝙蝠科不同。生殖附属腺复合体在功能或大小方面没有年度变化，但会因年龄（亚成体和成年体）而有所不同。这与在这些纬度地区描述的这些物种的年度生殖模式一致，即成年雄性全年都具有生殖活性。
