It is essential to know the reproductive biology and the morphology of the reproductive organs to increase animal production.
Penis impotent
In order to contribute to this knowledge and provides information on the ram reproductive morphology, the purpose of this work was to describe the distribution, based on light microscopy, of the collagen and elastic fibers in the ram penis.
For that, were collected transverse fragments of the penis root, sigmoid flexure, body and glans of seven rams. The specimens were fixed in paraformaldehyde for 24h and destined for the histological routine.
The extracellular matrix of the ram penis was composed of collagen and elastic fibers. The penis was enveloped by the tunica albuginea, consisting essentially of collagen fibers, which were arranged in two layers: an outer longitudinal and an inner circular. This tunic emitted septa that penetrated the corpus cavernosum.

The elastic fibers appeared transversely and longitudinally in the corpus cavernosum, corpus spongiosum, and next to the neurovascular bundle of the penis. This structure was not different to that reported for other domestic ruminants such as cattle and buffaloes.

É fundamental que se conheça a biologia reprodutiva e a morfologia dos órgãos reprodutores para o incremento da produção animal. Com o objetivo de contribuir para este conhecimento e fornecer informações sobre a morfologia reprodutiva de ovinos, o propósito deste trabalho foi descrever a distribuição, com base na microscopia de luz, das fibras colágenas e elásticas no pênis de ovinos.
Para tanto, foram coletados fragmentos transversais do pênis raiz, flexura sigmoide, corpo e glande de sete ovinos. Os exemplares foram fixados em paraformaldeído por 24h e destinados penis impotent rotina histológica. A matriz extracelular do pênis de ovinos estava constituída por fibras colágenas e elásticas. O pênis estava envolvido pela túnica albugínea, formada essencialmente por fibras colágenas, penis impotent estavam arranjadas em duas camadas: longitudinal externa e circular interna.

Stereological study of the elastic fiber and smooth muscle cell system in the bovine and buffalo penis.
The rabbit penis is covered by a capsule of connective tissue, the tunica albuginea, which projects intracavernous septa, especially in the corpus cavernosum. There are elastic fibers in the corpus cavernosum, corpus spongiosum, and in the tunica albuginea of the penis Maia et al.
Concentration of elastic system fibers in the corpus cavernosum, corpus spongiosum, and tunica albugínea in the rabbit penis. The concentration of elastic fibers in different penile regions is related to age-related changes in rabbits.

From one month of life, rabbits have a gradual increase in the concentration of these fibers. This trend is interrupted at two years, which may be related to initial changes due to senescence of the animals Abidu-Figueiredo et al. Age-related changes in the concentration of elastic fibers in different regions of the rabbit penis. Acta Cir. There are few reports on the distribution of elastic, collagen and muscle fibers in the penis in domestic or penis impotent animals.
