I found another interesting study. Apparently glucortecosteroids(the main ingredient in steroid anti inflammatories) in high concentration causes death to leydig cells.


"A second line of experiments examined whether apoptosis was evident in purified Leydig cells after administration of CORT in vivo. Male rats were subjected to bilateral adrenalectomy and were treated with CORT by ip injection twice daily at doses ranging from 2.5-7.5 mg/100 g BW starting 3 d after surgery. The frequency of Leydig cell apoptosis was measured at 12, 24, 48, and 72 h after the first injection. Administration of the 2.5-mg dose raised circulating CORT 5-10 times above normal basal concentrations, and LH levels sampled at these times were not altered in the treated animals. Increased Leydig cell apoptosis was measurable after 24 h of treatment, with an incidence of 21.1 +/- 1.8% in ALC compared with 5.7 +/- 0.8% in untreated controls (P < 0.05). Sharp reductions in immunocytochemical staining intensity were observed in the treated animals for a Leydig cell marker, 11beta-hydroxysteroid dehydrogenase, which occurred concurrently with decreased serum T levels. This was consistent with the hypothesis that CORT-mediated induction of apoptosis leads to declines in Leydig cell numbers, thereby affecting T production. These results suggest that excessive exposure to CORT initiates apoptosis in rat Leydig cells, potentially contributing to suppression of circulating T levels during stress and other conditions in which glucocorticoid concentrations are elevated."

This is what happened to me recently because of my stupidity.

If you are on medications or have a medical condition, always check with your doctor first before making any lifestyle changes or taking new supplements.  And low testosterone is a medical condition.
