OBJECTIVE: To investigate the effect of the method of tonifying the kidney and activating blood circulation on the testosterone secretion index (TSI) in late-onset hypogonadism (LOH) male patients with kidney deficiency and its possible mechanisms.
METHODS: We screened 60 LOH male patients with kidney deficiency based on the scores on Partial Androgen Deficiency in Aging Males (PADAM), the levels of serum total testosterone (TT) and luteinizing hormone (LH), and TSI (TT/LH). We randomly divided the patients into a Nan Geng Ning (NGN) group (n = 40, aged 55.02 +/- 11.37 years) and a control group (n = 20, aged 54.56 +/- 12.12 years) to be treated orally with NGN decoction and testosterone undecanoate capsules, respectively, both for 12 consecutive weeks. We obtained the scores on psychological status, physical status and sexual function and observed the changes in serum TT, LH and TSI after 4, 8 and 12 weeks of treatment.
RESULTS: Compared with the baseline, both the NGN and control groups showed a significant reduction after 12 weeks of medication in the LH level ([5.32 +/- 2.08] vs [4.89 +/- 1.46] IU/L and [5.36 +/- 2.07] vs [4.81 +/- 1.75] IU/L, P < 0.05), psychological status score (5.2 +/- 1.3 vs 2.7 +/- 1.4 and 4.8 +/- 2.2 vs 2.9 +/- 1.2, P < 0.05), physical status score (6.9 +/- 2.5 vs 2.9 +/- 1.6 and 7.1 +/- 2.7 vs 3.1 +/- 1.5, P < 0.05) and sexual function score (10.2 +/- 3.3 vs 4.5 +/- 2.9 and 9.8 +/- 3.1 vs 4.8 +/- 3.0, P < 0.05), but a remarkable increase in the TT level ([11.13 +/- 0.69] vs [14.55 +/- 0.75] nmol/L and [10.99 +/- 0.74] vs [14.74 +/- 0.83] nmol/L, P < 0.05) and TSI ([2.14 +/- 0.65] vs [2.99 +/- 0.72] nmol/IU and ([2.05 +/- 0.73] vs [3.11 +/- 0.65] nmol/IU, P < 0.05). However, no significant differences were found between the NGN and control groups at 12 weeks in LH ([4.89 +/- 1.46] vs [4.81 +/- 1.75] IU/L, P > 0.05), TT ([14.55 +/- 0.75] vs [14.74 +/- 0.83] nmol/L, P > 0.05), TSI ([2.99 +/- 0.72] vs [3.11 +/- 0.65] nmol/IU, P > 0.05), psychological status score (2.7 +/- 1.4 vs 2.9 +/- 1.2, P > 0.05), physi- cal status score (2.9 +/- 1.6 vs 3.1 +/- 1.5, P > 0.05) and sexual function score (4.5 +/- 2.9 vs 4.8 +/- 3.0, P > 0.05). There were no adverse events in either of the two groups throughout the whole experiment.
CONCLUSION: The method of tonifying the kidney and activating blood circulation could significantly improve the clinical symptoms of LOH with kidney deficiency and increase the patient's serum TT level and TSI. NGN decoction works on LOH by acting on the hypothalamic-pituitary-gonad axis.
