“…The penis of rabbits is of musculocavernous type (Farag, Elsayed, & Shoeib, 2017), as the spaces filled with blood are relatively large and the septa separating them are delicate and muscular (Dyce, Sack, & Wensing, 2009; Hafez & Hafez, 2013; Ribeiro, Abidu‐Fig ueiredo, Costa, Pereira‐Sampaio, & Chagas, 2013). Furthermore, smooth muscles form the most abundant component of the penile erectile tissue.…”

“…Furthermore, smooth muscles form the most abundant component of the penile erectile tissue. The lumen of the penile urethra is mainly lined by different types of epithelium from stratified cuboidal to columnar (Farag et al., 2017). Our study confirmed the musculocavernous nature of the rabbit penis.…”

“…Elastic fibres were abundantly present in the connective tissue between the vessels and arterial walls (Figure 1f). Previous studies indicated that the tunica albuginea surrounded only two cavernous bodies and appeared as a bilayered structure with an inner circular layer and an outer longitudinal layer (Brock, Hsu, Nunes, Von Heyden, & Lue, 1997; Farag et al., 2017; Hsu et al., 1994). However, in the present study, two layers of dense connective tissue were observed, but the boundary between them was not clearly demarcated.…”

“…The available literature provides an inconsistent description of the glans penis in rabbits. Some authors have reported the absence of this structure (Brewer, 2006), while some suggested that it was replaced by pars libra (Farag et al., 2017). According to Di Girolamo et al., (2017), in rabbits the glans penis is reduced, tapered and covered by a prepuce, whereas other authors did not describe any unusual features for this organ (Meredith & Lord, 2014).…”

This stereudy aimed at performing a histological and morphometric evaluation of the urethra and penis of male rabbits. Seven male New Zealand White rabbits weighing 2.1–3 kg were used in the study. The whole urethra, from the urinary bladder to the external urethral orifice, was dissected from the rabbits, and the tissue was sliced into sections at an interval of 2 mm. The sections were stained with haematoxylin–eosin, Masson–Goldner trichrome stain, Van Gieson's stain and Movat–Russell modified pentachrome stain. A detailed evaluation of the morphology and morphometry was performed. The parameters assessed were the type and height of epithelium, thickness and composition of connective tissue, and thickness and structure of muscularis. The histological structure of the rabbit urethra was found to be similar to humans. However, although the rabbits were found to have the same type of penis as the humans, the internal structure of the corpora cavernosa, the relative thickness of the tunica albuginea and the rudimentary glands of the penis were found to differ in these animals. The results of the present study may be useful in the designing of implants, drug testing or surgical procedures on the physiological and pathological urethra.
