Abstract
Mutations in transmembrane conductance of cystic fibrosis (CFTR) are found in men in couples followed for infertility and for which azoospermia associated with congenital bilateral absence of the deferential canal (CBAVD) were found in men. There is a frequent association between CFTR and CBAVD abnormalities. CBAVD exists in almost all men with cystic fibrosis and causes an obstructive azoospermia that cannot be treated surgically; this poses a diagnostic and therapeutic problem because its management remains complex. However, with the use of assisted reproductive techniques (ART), in particular the aspiration of testicular or epididymic sperm, the injection of intracytoplasmic sperm and in vitro fertilization, it is possible that men with CBAVD can produce offspring. We report the case of a 32-year-old patient who consulted for primary infertility evolving over the past 5 years (genetic advice was provided). The aim of this article is to show the diagnostic and therapeutic difficulties related to this particular form of male primary infertility. Recent assisted human reproduction techniques like Intracytoplasmic Sperm Injection (ICSI) or In Vitro Fertilization (FIV) offer very good results for couple consulting for infertility of man with CBAVD.
