A new Scyllaeidae of the genus Notobryon is described from Guadeloupe, in the Lesser Antilles. Notobryon caribbaeus sp. nov. is characterized by having the anterior pair of body lobes remarkably bigger than the posterior pair, a stomach with eight triangular plates, a black and very wide ampulla, a lemon-shaped bursa copulatrix and a complex and well-differentiated sponge-like prostate. The first Caribbean records of Notobryon were provisionally assigned to the Australian species Notobryon cf. wardi and later transferred to Notobryon panamica. However, the structure of the male genital system is one of the main morphological characters to discriminate species in the genus and the presence of a prostate in N. caribbaeus sp. nov. distinguishes it from N. panamica, which remains confined to the eastern Pacific. Of the remaining four species in the world, only Notobryon bijecurum shares this character, but its external anatomy is different: it lacks a bursa copulatrix and the deferent duct is much shorter. Notobryon caribbaeus sp. nov. was captured in the context of an intensive expedition (‘Karubenthos’) organized by the Muséum National d'Histoire Naturelle, Paris and its description raises the total inventory of sea slugs in Guadeloupe to 150.

The most frequently occuring abnormality of the male genital system in mammals is the failure of one or both testes to descend into the scrotum. The reasons for abdominal or inguinal retention of testes could be anatomic malformation, faulty development or hormone imbalance.Cryptorchidism has been associated with either greatly reduced or absent spermatogenesis (Kaueakami et al, 1984), and being a source of neoplasia. According to Stick (1980), germinal carcinoma cells have been believed to be the cause of teratomas in equine cryptorchid testicles. Neoplasia has been reported in descended testes of unilateral cryptorchid patients (Martin et al, 1981).No distinction has been made in relating the problem of cryptorchid testes to inguinal or abdominal retention. The purpose of this study is to record the morphological differences between inguinal and abdominal cryptorchid testes as an aid in diagnosis and prognosis.

Objective: Phimosis is define as unretractable prepuce and has two different clinical presentation; pathological (PaP) and physiological. Physiological phimosis (PhP) is a common condition in children that does not require treatment. In our study, we aimed to determine the actual requirement for circumcision in patients with phimosis who were recommended circumcision. Material and Methods: Children who were offered circumcision due to phimosis between July 2019 and January 2020 and applied to the pediatric surgery and pediatric urology outpatient clinic were included in the study. They were evaluated in terms of referring physicians, genital examination findings and requirement for circumcision. Results: Between the study dates, 199 patients applied for circumcision due to phimosis.  126 patients are under one year old, 73 patients are over one year old. PhP was present in 194 of the patients and PaP in 5 of them. While PaP is not detected in patients under one year of age, there are 5 patients with PaP over one year of age (2%). There was no requirement for urgent circumcision in any of the patients. Genital examination revealed incidentally undescended testicle in 3 patients and hydrocele in 12 children. Conclusion: Male genital system examination and pathological findings are not well known by physicians. We think that there is a need for detailed training for physicians regarding PhP and childhood testicle pathologies.
