CFTR Mutations in Congenital Absence of Vas Deferens
A qualitative diagnosis of infertility requires attention to female and male physical abnormalities, endocrine anomalies and genetic conditions that interfere with reproduction. Many genes are likely to be involved in the complex process of reproduction. Cystic fibrosis (CF) incidence varies in different White people populations (a higher incidence of CF is observed in northern–western European...
متن کامل[Congenital unilateral absence of the vas deferens].
A 10-year-old boy with cystic fibrosis (CF) (DeltaF508/G551D mutation) underwent an uneventful elective interval laparoscopic appendectomy. During routine laparoscopic inspection of the abdomen and groins, congenital bilateral absence of the vas deferens was noted. Pictures of the patient's internal inguinal ring noted at time of laparoscopy are presented and compared with a similar-aged patien...
متن کاملTrue duplication of the vas deferens.
We report true duplication of the vas deferens found at routine inguinal hernia repair. This rarity is described in the context of the embryologic model for other vas abnormalities.
متن کاملExpression and functional activity of phosphodiesterase type 5 in human and rabbit vas deferens.
The molecular mechanisms underlying the regulation of vas deferens (VD) motility and semen emission are still poorly understood. We now report evidence on VD expression of phosphodiesterase type 5 (PDE5), which regulates nitric oxide (NO)-induced relaxation and cGMP breakdown in smooth muscle cells. In human VD, the PDE5 abundance was relatively high (>3 x 10(6) molecules/microg total RNA), alt...
متن کاملSpinal cord segments controlling the canine vas deferens and differentiation of the primate sympathetic pathways to the vas deferens.
This study was undertaken to explore the spinal cord segments controlling the canine and human vas deferens and differentiation of the mammalian sympathetic pathways to the vas deferens. Thoracolumbar white communicating rami (WCR) were electrically stimulated in the dogs. Stimulation of the 1st, 2nd, 3rd, and 4th lumbar WCR elicited an elevation of intraluminal pressure of the vas deferens in ...
