PRL and tuberculosis: Spearman correlation showed that the prevalence of tuberculosis in male partners was positively correlated with DFI (R=0.492, p=0.000) and negatively correlated with testosterone (R=-0.120, p=0.012).<h4>Conclusions</h4>Among the couples with idiopathic PRL, male partners with a history of pulmonary tuberculosis (especially untreated pulmonary tuberculosis) are more prone to PRL, which maybe caused by high DFI and low testosterone.
