Isolated Congenital Bilateral absence of Vas deferens (CBAVD): A rare anomaly and diagnostic dilemma.
J Pak Med Assoc Jan ;53(8):372-3.

A 32-year old male shopkeeper presented with a 8year history of primary infertility. History and clinical examination were unremarkable. Two urologists examined the patient separately and both had reported clinically palpable vas deferens. Seminal examination on two occasions, showed low volume (less than 1.5m1) fructosepositive azoospermia. Hormonal profile including serum testosterone, prolactin, LH and FSH were normal. Scrotal exploration ± vaso-epididymal anastomosis was planned. At exploration, vas deferens was found to be bilaterally absent, epididymal head and body were dilated along with blindly ending tail. Epididymal aspirate showed numerous normally looking sperms. A transrectal ultrasound scan (TRUS) showed bilateral presence of seminal vesicle. Subsequently the patient was offered epididymal aspiration and intracytoplasmic sperm insemination.
