I dont know that gastrointestinal distress, liver toxicity and haemotological, inhibition of T cell proliferation, and natural killer cell activity and also inhibits antibody production side effects are good trade off's.  I'm sure not everyone get this but?
From what I found I would say Yes it effects testosterone.
"Fertility parameters of 10 men with chronic inflammatory bowel disease  under treatment with sulfasalazine for at least 5 years were compared to  those of 19 control subjects. Seminal parameters examined included  ejaculate volume, sperm number and concentration, sperm motility index,  sperm viability, pH, zinc concentration, prostaglandins E and F2-alpha,  prolactin and 7 classes of sperm morphology. In addition, plasma  concentrations of follicle-stimulating hormone, luteinizing hormone,  testosterone and prolactin were noted. The data indicate that  sulfasalazine therapy reduces semen quality and that this effect can be  reversed upon removal from therapy. This reversal is independent of  seminal prostaglandin concentrations."
