BACKGROUND Congenital absence of the vas deferens is an important cause of obstructive azoospermia, and the lack of an imaging diagnostic test is a critical problem. The aim of this study is to discuss the use of ultrasonography in congenital absence of vas deferens, including dysplasia of the epididymis and the seminal vesical. MATERIAL AND METHODS Five fresh spermatic cord specimens were dete...

Repair of congenital groin hernia/hydrocele and orchidopexy for the undescended testis are the most common surgical procedure performed by pediatric surgeons. Up to 1% of all men have been reported to have a congenital unilateral absence of the vas deferens (CUAVD).1 Previous studies have suggested that ipsilateral renal anomalies are present in up to 91% of men with a congenital unilateral abs...

A qualitative diagnosis of infertility requires attention to female and male physical abnormalities, endocrine anomalies and genetic conditions that interfere with reproduction. Many genes are likely to be involved in the complex process of reproduction. Cystic fibrosis (CF) incidence varies in different White people populations (a higher incidence of CF is observed in northern–western European...

OBJECTIVES Within a randomised trial of neonatal vitamin A supplementation (VAS) in Guinea-Bissau, neonatal VAS did not affect overall infant mortality. We conducted a post-hoc analysis to test the hypothesis that neonatal VAS primes the response to subsequent vitamin A. METHODS All trial children were offered VAS after follow-up ended at 1 year of age (FU-VAS). We compared mortality between ...

BACKGROUND Congenital unilateral absence of the vas deferens occurs in 0.5%-1.0% of males. It has been associated with various genitourinary abnormalities, including renal agenesis. We report a case of congenital unilateral absence of the vas deferens found incidentally during vasectomy in a patient with known unilateral renal agenesis. CASE PRESENTATION A 24-year-old male presented to our ur...

A 10-year-old boy with cystic fibrosis (CF) (DeltaF508/G551D mutation) underwent an uneventful elective interval laparoscopic appendectomy. During routine laparoscopic inspection of the abdomen and groins, congenital bilateral absence of the vas deferens was noted. Pictures of the patient's internal inguinal ring noted at time of laparoscopy are presented and compared with a similar-aged patien...

Background: Mutations of the cystic fibrosis transmembrane conductance regulator (CFTR) gene can cause congenital bilateral absence of vas deferens. Yet, the spectrum and frequency of CFTR mutations in Indian males with congenital absence of vas deferens (CAVD) is unknown. Materials and Methods: We investigated 50 Indian males, diagnosed with unilateral or bilateral absence of vas deferens at t...

Introduction and Aims. Congenital absence of the vas deferens is an uncommon anomaly and this clinical condition is responsible for up to 1-2% of male infertility. It can be either unilateral or bilateral and the associated anomalies include cryptorchidism, seminal vesicles and ejaculatory ducts anomalies, and renal anomalies such as renal agenesis. We hereby present a case of congenital unilat...
