Abstract

The accessory sex organs play a crucial role in reproductive function, yet limited research exists on age-related changes in these structures in jacks. In the present work, the accessory sex organs of 60 Egyptian jacks were classified according to their age into young (n = 15), adult (n = 25) and senile (n = 20). Jacks were euthanized and the accessory sex organs were immediately separated and collected. Morphometric measures of the penis, ampulla, seminal vesicles, prostate and bulbourethral gland, including length and weight, were determined. Tissue samples from the ampulla, seminal vesicles, prostate and bulbourethral glands were collected, processed and stained with H&E for histomorphometric examination. Our findings reveal significant age-related alterations in the penial weight and length, the structure and secretory activity of the accessory sex glands, shedding light on the physiological changes that occur with advancing age in this species. Insights gained from this analysis can improve reproductive management practices and contribute to the conservation of donkey populations.

埃及马（Equus asinus）副性器官的年龄相关变化：形态学和组织学研究。

副性器官在生殖功能中起着至关重要的作用，但关于这些结构在jacky中与年龄相关的变化的研究有限。本研究将60只埃及千头马的辅助性器官按年龄分为青年（n = 15）、成年（n = 25）和老年（n = 20）。杰克被安乐死，附属性器官被立即分离和收集。测定阴茎、壶腹、精囊、前列腺和尿道球腺的形态测量，包括长度和重量。收集壶腹、精囊、前列腺和尿道球腺组织标本，处理后用H&E染色进行组织形态学检查。我们的研究结果揭示了阴茎的重量和长度、副性腺的结构和分泌活性与年龄相关的显著变化，揭示了该物种随着年龄增长而发生的生理变化。从这一分析中获得的见解可以改善生殖管理实践，并有助于驴种群的保护。

期刊介绍： The journal offers comprehensive information concerning physiology, pathology, and biotechnology of reproduction. Topical results are currently published in original papers, reviews, and short communications with particular attention to investigations on practicable techniques. Carefully selected reports, e. g. on embryo transfer and associated biotechnologies, gene transfer, and spermatology provide a link between basic research and clinical application. The journal applies to breeders, veterinarians, and biologists, and is also of interest in human medicine. Interdisciplinary cooperation is documented in the proceedings of the joint annual meetings. Fields of interest: Animal reproduction and biotechnology with special regard to investigations on applied and clinical research.
