Twenty penis from normal boars were injected with various media at known reservoir pressures and examined by radiography, dissection, maceration, clearing and sectioning. Injections into the corpus spongiosum penis (csp) produced dorsal deviation and clockwise spiral twisting. The ccp was traversed by a system of large longitudinal cavernous spaces. The csp consisted of one large vascular space, its walls joined by trabeculae which were close together ventrally and further apart dorsally. The corpus spongiosum glandis (csg) was a vascular network within the penile integument communicating with the csp by fine vascular spaces around the urethral orifice. The penile arteries and veins were supplied and drained by the internal pudendal vessels. The ccp was drained from its crura by the v profunda penis but no venous drainage of this cavernous body was demonstrated within the body of the penis. The csp was drained from its bulb by the v bulbi penis; its distal extremity was drained by two large veins which ran proximally enclosed by the tunica albuginea of the csp. The right vein was always much larger than the left vein and at the sigmoid flexure the two united to form the right tributary of the v dorsalis penis. The csg and the entire penile integument were drained by the left tributary of the v dorsalis penis; the csg was also drained by one or both of the ventral veins of the csp. Blood from the scrotum was drained by the v circumflexa perinealis and v perinealis ventralis into the v dorsalis penis and v penis. A large dorsal lymphatic vessel drained lymph from the body of the penis into the pelvic lymph nodes. No connections with the superficial inguinal lyphocentres were identified.
对20头正常公猪的阴茎在已知的储器压力下注射各种介质，并通过X射线摄影、解剖、浸软、透明化和切片进行检查。向阴茎海绵体（csp）注射会导致背侧偏斜和顺时针螺旋扭曲。阴茎海绵体（ccp）由一个大的纵向海绵状空间系统穿过。csp由一个大的血管腔组成，其壁由小梁连接，小梁在腹侧靠得很近，在背侧则相距较远。阴茎头海绵体（csg）是阴茎被膜内的一个血管网络，通过尿道口周围的细小血管腔与csp相通。阴茎的动脉和静脉由阴部内血管供应和引流。ccp从其脚通过阴茎深静脉引流，但在阴茎体内未显示该海绵体的静脉引流。csp从其球部通过阴茎球静脉引流；其远端由两条大静脉引流，这两条静脉向近端延伸，被csp的白膜包裹。右侧静脉总是比左侧静脉大得多，在乙状弯曲处，两者汇合形成阴茎背静脉的右支。csg和整个阴茎被膜由阴茎背静脉的左支引流；csg也由csp的一条或两条腹侧静脉引流。来自阴囊的血液通过会阴旋静脉和会阴腹侧静脉引流到阴茎背静脉和阴茎静脉。一条大的背侧淋巴管将阴茎体的淋巴引流到盆腔淋巴结。未发现与浅表腹股沟淋巴中心有联系。
