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 died 12 hours ago, was submitted to spermatozoa retrieval for cryopreservation, with surgical bilateral resection in bloc of the proximal part of vas deferens, testicle and e...

Cystic fibrosis (CF) is usually considered a rare disease in the Indian population. Two studies have reported on the frequency of cystic fibrosis transmembrane conductance regulator (CFTR) gene mutations in Indian males with congenital absence of the vas deferens (CAVD), however, data on the spectrum of CFTR gene mutations are still lacking. Therefore, the present study was designed to identify...

The present study was undertaken to evaluate the frequency and nature of mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene in infertile patients undergoing intracytoplasmic sperm injection. A total of 90 patients were screened for a panel of 10 mutations in the CFTR gene frequently involved in congenital absence of the vas deferens (CAVD); the patients included 14...

Sequencing of all 27 CFTR exons, including flanking intronic regions, and a search for large rearrangements were undertaken in the remaining 18 DNA samples. Calling all the patients back for further familial genetic studies could not be considered and we assumed that two identified mutations are located in trans. ORs were calculated and proportions were compared with prior probability using the...

Duplication of the vas deferens is a rare anomaly, defined as the presence of two distinct vasa deferentia within one spermatic cord, with only 28 cases reported worldwide since 1959. We report the case of a 63-year-old man with a duplicate vas deferens, presenting with abdominal pain from bowel obstruction secondary to incarcerated inguinal hernia. Spermatic cord dissection during hernioplasty...
