The penis of adult rats comprises the corpus cavernosum penis and the proximal and distal segments of os penis which are situated proximal-distally in this order. Androgens are necessary for the phenotypic differentiation of these tissues. In the present study, genital tubercular mesenchyme of foetal rats was recombined with or without homologous or heterologous epithelia and transplanted benea...

In this study, histological and macroanatomical structures of porcupine penis were examined on 3 adult male porcupines. The non-erectile position of porcupine penis was directed to caudal. There was an obvious collum penis. Glans penis with a black colour was easily distinguished from corpus penis which had a white color. There were cornified papillae covering on both the glans penis and corpus...

background: the persian squirrel (sciurus anomalus) is a member of the family sciuridae in the middle east and very little information is available about the anatomy of the different organs of this animal. objectives: in this study, histological and macro anatomical structures of penis were examined on 6 adult male persian squirrels. methods: each animal was sacrificed after anesthesia with ket...

pulmonary agenesis is a very rare condition and many of them are associated with a variety of cardiac and non-cardiac malformations. we report an eight-month old girl with chronic lung infection due to right sided pulmonary agenesis without any associated major cardiac or non-cardiac abnormalities. the case brings in forth the importance of investigating any infant presenting with features of c...

OBJECTIVES The aim of this study was to evaluate the association between tooth agenesis and skeletal malocclusions in Brazilian non-syndromic orthodontic patients. MATERIAL AND METHODS Pretreatment orthodontic records of 348 patients of both genders and with various skeletal malocclusions were examined. Tooth agenesis was evaluated in panoramic radiographs. Angular measurements were taken fro...

BACKGROUND Complete absence of a hemidiaphragm or diaphragmatic agenesis in adulthood is rare with only one previous report in the literature. Its significance in relation to performing laparoscopic procedures has not been documented previously. METHODS We report a case of previously undiagnosed diaphragmatic agenesis in adulthood precluding laparoscopic cholecystectomy and comprehensively re...

BACKGROUND The aim of the study was to describe the shear wave velocity (SWV) values of the penis by virtual touch tissue quantification (VTTQ) and to examine the clinical usefulness of this procedure in evaluation of the rigidity changes in penile erection. PATIENTS AND METHODS.: VTTQ was performed in 37 healthy volunteers. In the course of erection, SWV values of glans penis, corpus penis an...

Dear Editor, Penoscrotal transposition (PST) is an infrequent congenital external genital malformation in which the scrotum is located superior and anterior to the penis(1). PST can be defined as either complete or incomplete according to the positional exchanges between the penis and scrotum and both forms of PST are generally linked with hypospadias. Incomplete transposition is the common for...

bilateral femoral agenesis is a rare anomaly.  to the best of our knowledge, only three cases of simple congenital anomaly and three cases associated with femoral facial syndrome have been reported.  here, we describe a simple form of bilateral femoral agenesis observed in one of the 2 dead fetuses delivered after termination of a 24-week twin pregnancy of a normal mother.  post-mortem x-ray ex...
