Case Reports in Surgery, 2016 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,

Expanding the phenotypic and genetic spectrum of Chinese patients with congenital absence of vas deferens bearing CFTR and ADGRG2 alleles [PDF]
Andrology, 2019 Congenital absence of vas deferens (CAVD) is a major cause of obstructive azoospermia. Mutations in CFTR and ADGRG2 are responsible for this disease.

Physiological and pharmacological aspects of the vas deferens—an update
Frontiers in Pharmacology, 2013 The vas deferens, a muscular conduit conveying spermatozoa from the epididymis to the urethra, has been used as a model tissue for smooth muscle pharmacological and physiological advancements. Many drugs, notably α-adrenergic antagonists, have effects on

Genetics of the congenital absence of the vas deferens
Human Genetics, 2020 Congenital absence of the vas deferens (CAVD) may have various clinical presentations depending on whether it is bilateral (CBAVD) or unilateral (CUAVD), complete or partial, and associated or not with other abnormalities of the male urogenital tract ...

An atlas of cell types in the mouse epididymis and vas deferens
eLife, 2020 Following testicular spermatogenesis, mammalian sperm continue to mature in a long epithelial tube known as the epididymis, which plays key roles in remodeling sperm protein, lipid, and RNA composition.

Comorbidity of the congenital absence of the vas deferens
Andrologia, 2018 Congenital absence of the vas deferens (CAVD) is a relatively rare anomaly that may contribute to male infertility. The aim of this study was to evaluate the clinical features of patients with CAVD and to emphasise some pathological conditions that may ...
