Sometimes the blockage in the reproductive tract after vasectomy causes pressure to build up in the epididymis, which leads to distension in the tubules and, in time, rupture.

Ruptures are usually asymptomatic and not problematic.

Concern about the possibility of long-term risks of vasectomy was fueled by findings that vasectomy may accelerate development of atherosclerosis in monkeys, Results of studies conducted over nearly four decades, however, provide little evidence of any significant long-term side effects of vasectomy.

These findings were confirmed by Naik and associates who demonstrated that, in 78 men vasectomized for 1–8 years, seminal concentrations of maltase, in addition to prolactin, zinc, and magnesium, were significantly lower than in 22 nonvasectomized men of normal fertility.

The implications of these findings on changes in the secretory function of the prostate after vasectomy remain unknown.

Epididymitis following vasectomy is uncommon, with most studies reporting rates of approximately 1–3% of men who have had a vasectomy, but rarely have unvasectomized controls been included in these studies.

On ultrasound examination, vasectomized men had a significantly higher incidence of thickened epididymides, epididymal tubular ectasia (when the normally invisible epididymal tubules are visible), sperm granulomas and mobile echogenicities (thought to be clumps of sperm trapped within dilated epididymal tubules) compared to non-vasectomized controls.

In each, investigators identified retrospectively a group of men who were known to have had vasectomies and a comparison group of men not known to have had a vasectomy.

The occurrence of hospitalizations after identification for the study was determined by computer-record linkage.

The nerves involved in erectile function and ejaculation are not affected, and vasectomy does not lead to impotence or other sexual difficulties.

incidence of impotence was 1.9/1000 man-years (MY) of observation in men with vasectomy and 1.7/1000 MY in men without vasectomy, a difference that was not statistically significant.

Although some early prospective studies suggested that mean plasma levels of testosterone, luteinizing hormone (LH), and estradiol increased after vasectomy when compared with mean hormone levels measured before vasectomy, the changes were found to be within the normal range for adults.

generated sufficient concern that a large number of studies regarding endocrine function in man have been done.

Vasectomy has been shown to affect gene expression and the synthesis of various proteins in the human epididymis, alterations that in some cases appear irreversible following vasovasestomy (i.e. Some of these proteins may play a critical role in sperm maturation and may be responsible, at least in part, for the fact that pregnancy rates following vasovasestomy are consistently lower than rates of appearance of sperm in the ejaculate after vasectomy reversal (see Vasectomy Reversal chapter).
