PURPOSE To determine the prevalence of unilateral absence of vas deferens (UAVD) in men with both testes seeking vasectomy. MATERIALS AND METHODS Computerized charts of 23.013 patients encountered between January 1994 and December 2013 in one university hospital and two community clinics of Quebec City, Canada, were searched. Pre-vasectomy consultation, operative reports and semen analysis re...

BACKGROUND The aim of this work was to investigate the mechanisms by which chronic malnutrition (CM) affects vas deferens function, leading to compromised reproductive capacity. Previous studies have shown that maternal malnutrition affects the reproductive tracts of adult male offspring. However, little is known about the effects of CM, a widespread life-long condition that persists from conce...

BACKGROUND Mutational combinations of the cystic fibrosis transmembrane conductance regulator, CFTR, gene have different phenotypic manifestations at the molecular level with varying clinical consequences for individuals possessing such mutations. Reporting cystic fibrosis transmembrane conductance regulator mutations is important in understanding the genotype-phenotype correlations and associa...

This study investigated whether transient, neonatal (days 2-12) treatment of rats with the potent oestrogen, diethylstilboestrol (DES), altered the structure of the cauda epididymis/vas deferens in adulthood, and if the changes observed related to altered development of basal cells in early puberty. Neonatal treatment with 10 microg DES resulted in the following during adulthood: (a) coiling of...

Reserpine induced supersensitivity to norepinephrine (NE) in rat vas deferens was sought by alteration of Mg++ and Ca++ concentration in incubation medium in the absence and presence of EDTA. Vas deferens incubated in Mg++ free and Mg++ excess media showed supersensitivity and subsensivity to NE respectively. Alterations in the sensitivity to NE produced by varying the concentrations of Mg++ we...

background: about 10% of infertilities with obstructive azoospermia are congenital and caused by cf gene mutations. m469i mutation was observed for the first time in taiwanese patients. this mutation not only causes cf, but also may be the origin of infertility too. objective: in this study, we aimed in designing a rapid, reliable rflp-pcr procedure for detection of m469i mutation. the correlat...
