Vasectomy re-reversal: effectiveness and parameters associated with its success
Int. braz. j. urol; 47 (3), 2021
ABSTRACT Introduction: When the vasectomy reversal (VR) fails, and the patient desires natural conception with his sperm, vasectomy re-reversal (VRR) is the only alternative. Purpose: To determine the VRR effectiveness and whether specific parameters can be associated with its success. Materials and M...
Seasonal variations of male reproductive parameters of Tomodon dorsatus from Southeastern Brazil
Pesqui. vet. bras; 41 (), 2021
The morphology of the male reproductive tract of Tomodon dorsatus was described in the austral seasons of the year considering macroscopic and microscopic variables. For this purpose, 56 specimens from the herpetological collection of the "Instituto Butantan" were used. Fragments of the testes, kidneys a...
Does a bilateral polypropylene mesh alter the duct deferens morphology, testicular size and testosterone levels? Experimental study in rats
Acta cir. bras; 35 (2), 2020
Abstract Purpose To evaluate the effect of a PP mesh on duct deferens morphology, testicular size and testosterone levels. Methods Forty adult male rats were distributed into groups: 1) no surgery; 2) inguinotomy; 3) mesh placed on the duct deferens; and 4) mesh placed on the spermatic funiculus. Aft...

Sperm morphophysiology in different sections of the rooster reproductive tract
Int. j. morphol; 37 (3), 2019
It is important to know the morphological changes that occur in the spermatozoa of rooster during their passage through the reproductive tract, which help to understand what they acquire their fertilization capacity. The morphophysiological changes related to the capacitation and acrosomal reaction proce...
Portable model for vasectomy reversal training
Int. braz. j. urol; 45 (5), 2019
ABSTRACT Objectives To validate an experimental non-animal model for training of vasectomy reversal. Materials and Methods The model consisted of two artificial vas deferens, made with silicon tubes, covered by a white resin, measuring 10 cm (length) and internal and external diameters of 0.5 and 1.5...
Vasitis: a clinical confusion diagnosis with inguinal hernia
Int. braz. j. urol; 45 (3), 2019
Abstract Vasitis or inflammation of the vas deferens is a rarely described condition categorized as either generally asymptomatic vasitis nodosa or the acutely painful infectious vasitis. Vasitis nodosa, the commonly described inflammation of the vas deferens, is benign and usually associated with a hist...
Crossover transseptal vasovasostomy: alternative for very selected cases of iatrogenic injury to vas deferens
Int. braz. j. urol; 45 (2), 2019
ABSTRACT Inguinal herniorraphy is a possible cause of iatrogenic seminal tract obstruction. Diagnosing and correcting these vasal injuries can be challenging. Successful re-anastomosis is technically challenging, with relatively low success rates. An uncommon alternative for selected cases is the crossov...
Imposex in Stramonita haemastoma from coastal sites of Cartagena, Colombia
Braz. j. biol; 78 (3), 2018
Abstract Imposex is the development of male sexual characteristics caused by the toxic effects of some chemicals that acts as an endocrinal disruptor. Antifouling paints contain these chemicals. Cartagena lacks studies to indicate the extent of imposex in its coastal waters. The aim of this study was to ...

Spermatozoa retrieval for cryopreservation after death
Int. braz. j. urol; 44 (1), 2018
ABSTRACT Objectives To describe the retrieval spermatozoa technique for cryopreservation after death, including the proximal part of vas deferens. Material and Methods A 28-years old man, with previous history of infertility, who had died 12 hours before, was submitted to spermatozoa retrieval for cryo...
