While I would be keen to hear more about this, if only to facilitate a literature search, I am skeptical at the moment.
I take this position because the report here has the form of a 2nd hand rumor, and at least one other member's initial search did not turn up anything, and a lit search I just did in Web of Science did not turn up anything of concern (in fact there was some reassurance). Also, I wonder if this is a garbling of older/known short term and reversible effects of sulphasalazine on male sperm count.
I use the word "rumor" because we have the hearsay report of an ambiguously credentialed "clinician" at a urology center saying something (vaguely remembered) about testosterone and 5-asa (& Remicade). The clinician speculated this based on some symptoms, but not on an actual test of T levels (which is now scheduled). Further, google and Web of Science searches do not hit on this, excepting some old (e.g., 1988) reports of lower (but still normal) T levels with 5-asa.
Influence of Salazosulphapyridine and 5-Aminosalicylic Acid on Seminal Qualities and Male Sex Hormones

Seminal abnormalities are a common side effect of Salazosulphapyridine (SASP) treatment. We evaluated semen qualities and sex hormone concentrations in 11 patients with inflammatory bowel disease (IBD) during SASP treatment and 4 months after replacing SASP with an oral slow-release preparation of 5-aminosalicylic acid (5-ASA). Significant improvement in sperm count (p < 0.01), morphology (p < 0.02), and motility (p < 0.02) could be observed during 5-ASA therapy, in comparison with SASP treatment. Three pregnancies occurred during the study period. The serum concentrations of gonadotrophins, prolactin, and sex hormone-binding globulin were normal in all patients and not significantly different in the two treatment periods. The mean total testosterone concentration decreased significantly (p < 0.02) after 5-ASA substitution, together with serum albumin (p < 0.005), although all values remained within normal limits. The apparent free testosterone concentration was not significantly different in the two treatment periods. It is concluded that a significant improvement in semen quality can be obtained in male patients with IBD after replacing SASP with 5-ASA.

There is some literature showing Remicade (a TNF antogonist drug) not influencing T (or other hormone) levels.
Ernestam, S., I. Hafstrom, et al. (2007). "Increased DHEAS levels in patients with rheumatoid arthritis after treatment with tumor necrosis factor antagonists: Evidence for improved adrenal function." Journal of Rheumatology 34(7): 1451-1458. (PMCID:
Objective. To determine if major reduction of inflammation with longterm tumor necrosis factor (TNF) antagonist treatment has any influence on the adrenal and gonadal axes in patients with rheumatoid arthritis (RA). Methods. Forty-eight patients with RA were treated with infliximab or etanercept for 2 years. Disease activity, clinical response, and physical function were evaluated and serum levels of high sensitivity C-reactive protein and interleukin 6 were analyzed before start of treatment and after I and 2 years. At the same timepoints adrenocorticotropic hormone (ACTH), cortisol, and dehydroepiandrosterone sulfate (DHEAS) were analyzed; luteinizing hormone (LH), estradiol, and testosterone were analyzed as well in 18 male patients. Results. DHEAS increased (p < 0.05) after 1 and 2 years of treatment with TNF antagonists. No change in serum levels of ACTH, cortisol, LH, estradiol, or testosterone was recorded during the 2 years. The increased levels of DHEAS correlated with improved physical function measured by Health Assessment Questionnaire (p < 0.01). There was no correlation between hormone levels and clinical response or inflammatory markers. A longitudinal stability in individual hormone levels was found between baseline and 2 years, most markedly for DHEAS levels (r(s) = 0.90, p < 0.01). A female subgroup characterized by low levels of DHEAS had a lower age at disease onset. Conclusion. The increased DHEAS levels may indicate an improved adrenal function during 2 years' treatment with TNF antagonists. Improved physical function, correlated to increased DHEAS levels, may be an effect of better adrenal function during powerful anti inflammatory treatment. The stability in individual hormone levels suggests a stable hormonal homeostasis, independent of inflammatory activity.
Of course the effect might take longer than 2 years to show. ... So ***this is a good topic for critical discussion***, but it would be very very premature to just accept an imprecise recounting of some clinicians comments as facts. Just the fact that 5-asa and anti TNF drugs are so different, I am immediately curious about a comment that patients treated with either (?) or both (?) display low T for their age.
.... and even if the correlation of low T and certian IBD drugs was established as fact, this would not mean there was a causal relation. Other commonly used drugs (like steroids) or something related to IBD might ultimately be found to be the root cause. Perhaps more disconcerting, we then have another member, who has been seen to have a great fear of medicine, immediately embrace the rumor, and declare he KNEW 5-asa had to be bad stuff. I am not sure if the uncritical acceptance is more saddening, or if it is the potential for other board readers to "catch" the uncritical acceptance. Either way, it would be nice if such an important discussion remained free of premature and/or over-reactions.
As for Low T, it can be FREE or TOTAL. There are a number of conditions, some disease, and some human genetic variation, that bind T in our systems. in response to this bound (unusable) T, the system makes more T. SO, in most cases it is the FREE T that needs to be looked at. In this case, we do not even know if a test was ordered for TOTAL or FREE or both.
As noted above, one study I found did see a drop in TOTAL T, but did not see any drop in FREE T. ("The mean total testosterone concentration decreased significantly (p < 0.02) after 5-ASA substitution, together with serum albumin (p < 0.005), although all values remained within normal limits. The apparent free testosterone concentration was not significantly different in the two treatment periods"). So, there is some possibility 5-asa binds some T, decreasing total T showing in tests, but the necessary free T, seems unaffected. Of course, further study would be reassuring.

.... and it would be great to get the exact term the clinician used.
