چکیده

Five mature dairy bulls were killed 10 weeks after unilateral vasectomy. Testes on the vasectomized side weighed 67% of the contralateral controls (P<.O1) and contained only 34% as many spermatids as the control testes (P<.01). Since a previous report showed little or no change in spermatogenesis in younger bulls at 23 weeks after vasectomy, possibly vasectomy temporarily interrupts spermatogenesis in bulls. In the caput-corpus epididymidis and in the cauda epididymidis on the occluded side, sperm numbers were 20% (P<.01) and 49% (P<.01) of those in the control side.

Effects of Chemical Sympathectomy on Contralateral Testicular Histology and Fertility in Unilateral Vasectomy

Unilateral obstruction or injury to the vas deferens can result in significant injury to the contralateral testicle. Although various pathways have been proposed, the mechanism of contralateral testicular deterioration remains controversial. The present animal study was performed to evaluate the effects of unilateral vasectomy on ipsilateral and contralateral testicular histology and fertility ...

Bilateral effect of unilateral vasectomy on testicular testosterone biosynthesis.

Twelve immature male dogs underwent a left vasectomy (group A). An additional five underwent a sham operation (group B). Sixteen weeks after the surgery, the bilateral mean values for caudal epididymal sperm content, the percentage of motile spermatozoa, intratesticular testosterone concentration, and testicular secretion of androgen-binding protein (in vitro) were significantly lower in group ...

The effect of unilateral vasectomy on testosterone and testicular parameters in the adult male African giant rat (Cricetomys gambianus).

BACKGROUND The effects of vasectomy on spermatogenesis and reproductive parameters are recognized to be specie-dependent with marked differences in levels of perturbations observed. OBJECTIVES To assess the impact of unilateral vasectomy on testosterone level and other testicular parameters in the male African giant rat (AGR) (Cricetomys gambianus). METHODS Sixteen adult male AGRs weighing ...

The histology and the proapoptotic control in the ipsilateral and the contralateral testes following unilateral vasectomy.

OBJECTIVE The aim of this study was to enlighten both the testicular histology and the genetic aspects of the apoptotic process. Thus an experimental study was designed with a model of unilateral vasectomy. METHODS Twenty-two adult male rats were used and 4 main groups were formed. The first (A), the second (B), the third (C), and the fourth group (D) consisted of 4, 4, 4 and 10 rats respecti...

Chronic pain after vasectomy: a diagnostic and treatment dilemma.

Vasectomy is a very common operation and has been accepted as a method of family planning by ≈ 42 million couples worldwide. While it is usually a well-tolerated and highly effective form of birth control, it has a risk of significant morbidity in ≈ 1% of patients [1]. One particularly troubling complication after vasectomy is chronic testicular pain, which has been defined as intermittent or c...
