Abstract
Congenital absence of the vas deferens (CAVD) is a syndrome with a heterogeneous presentation: bilateral (CBAVD) or unilateral (CUAVD), complete or partial and associated or not with other anomalies of the male urogenital system. A turning point came in 1968 when CBAVD was associated with cystic fibrosis and its CFTR gene mutations. Genetic studies then revealed that a minority of CBAVD but a majority of CUAVD are CFTR-independent. In the literature, reference is classically made to two sources from the 18th and 19th century: Hunter and Reverdin. This scarcity prompted us to look for additional observations of CAVD. By a meticulous bibliographical search, we identified a corpus of 10 European observations (8 CUAVD and 2 CBAVD) some of them richly illustrated. They were collected between 1755 and 1876 throughout adult men autopsies. We also provided their primary and unambiguous sources. Analysis of the reported data revealed some interesting facts: both CBAVD cases were unlikely linked to cystic fibrosis and half of CUAVD cases were associated with an ipsilateral kidney absence, suggesting a CFTR-independent pathophysiology. Moreover, the anatomical details of the anomalies raise interesting embryological questions we have tried to address in the light of current data. This work made it possible to identify new historical sources dealing with male genital tract pathologies. It sheds light on the origins of andrology and opens up interesting prospects for research and education in the field.
期刊介绍:
Andrology is the study of the male reproductive system and other male gender related health issues. Andrology deals with basic and clinical aspects of the male reproductive system (gonads, endocrine and accessory organs) in all species, including the diagnosis and treatment of medical problems associated with sexual development, infertility, sexual dysfunction, sex hormone action and other urological problems. In medicine, Andrology as a specialty is a recent development, as it had previously been considered a subspecialty of urology or endocrinology
