Abstract
We present a case of primary infertility with features of hypogonadism in a male patient with lepromatous leprosy who had remained undiagnosed for 3 years. On investigation, azoospermia and deranged gonadotropin levels with normal serum testosterone were noted and the patient was initiated on multibacillary-multidrug therapy with the primary aim of treating the disease. Although the cutaneous lesions improved within 6 weeks, remarkably infertility was reversed in 2 months-with concomitant normalization of luteinizing hormone, follicle stimulating hormone, and sperm count-an outcome that was unexpected. While reiterating leprosy as a cause of infertility, we discuss the probable mechanism for the efficacy of multidrug therapy in what seemed to be an irreversible outcome of advanced lepromatous leprosy.
