Abstract:
A prospective study of effects of vasectomy on the plasma
levels of testosterone, estradiol, follicle-stimulating hormone
(FSH), and luteinizing hormone (LH) was instituted. Postvasectomy
plasma hormone levels were compared with prevasectomy, base
line levels. Beginning at 6 months after vasectomy, mean plasma
testosterone levels demonstrated a statistically significant
elevation, mean plasma estradiol levels were lower, mean plasma
LH levels were elevated, and mean plasma FSH levels were unchanged.
By 2 years after vasectomy, a slight plasma FSH elevation
had occurred, plasma estradiol levels had returned to base
line, and plasma testosterone and LH levels remained elevated.
These changes, although significant statistically, did not
exceed the normal ranges found in normal adult males in our
laboratory and were of unclear physiologic significance. Thus,
it can be concluded from this study of 56 men studied for
2 years, 148 men studied for 1 year, and 182 men studied for
6 months after vasectomy that no adverse hormonal effects
of vasectomy have been demonstrated
