OBJECTIVE: To observe the therapeutic effect of governor vessel moxibustion combined with wenyang yiqi qiwei decoction on erectile dysfunction (ED) with spleen-kidney deficiency and to explore the possible mechanism. METHODS: A total of 130 ED patients with spleen-kidney deficiency were randomized into an observation group (65 cases, 2 cases dropped off) and a control group (65 cases, 3 cases dropped off). The control group was given wenyang yiqi qiwei decoction orally, one dose daily. On the basis of the treatment in the control group, governor vessel moxibustion was applied from Dazhui (GV 14) to Yaoshu (GV 2) in the observation group, 110 min a time, once a day. The treatment of 4 weeks was required in both groups. Before and after treatment, 5-question international index of erectile function (IIEF-5) score, erection quality scale (EQS) score, erectile hardness assessment (EHS) score, TCM syndrome score, serum testosterone (T) level and vascular endothelial function indexes (prostaglandin I2 [PGI2], endothelin-1 [ET-1] and nitric oxide [NO] levels) were observed respectively, and the clinical efficacy was evaluated in both groups. RESULTS: After treatment, the scores of IIEF-5, EQS, EHS and serum levels of T, PGI2, NO were increased compared before treatment (P<0.01), the TCM syndrome scores and serum ET-1 levels were decreased compared before treatment (P<0.01) in the two groups; the scores of IIEF-5, EQS, EHS and serum levels of T, PGI2, NO in the observation group were higher than those in the control group (P<0.01, P<0.05), the TCM syndrome score and serum ET-1 level were lower than those in the control group (P<0.01, P<0.05). The total effective rate was 88.9% (56/63) in the observation group, which was superior to 74.2% (46/62) in the control group (P<0.05). CONCLUSION Governor vessel moxibustion combined with wenyang yiqi qiwei decoction can improve the erectile function and increase the erection hardness and quality in ED patients with spleen-kidney deficiency, its mechanism may relate to improving serum T level and vascular endothelial function.

testosterone (T) boosting supplements to naturally improve T levels. We evaluated the composition and advertised claims of “T boosting” supplements, and supporting published evidence.MATERIALS AND METHODS: Fifty “T booster” supplements were evaluated for active ingredients and product claims, discovered via Google search. PubMed was reviewed for any literature supporting the claims, followed by review of Recommended Daily Allowance (RDA) and upper tolerable intake level (UL) for each component.RESULTS: Ninety percent of supplements claimed to “boost T”, 50% “improve libido”, and 48% “feel stronger”. One-hundred nine unique components were found, with a mean number of 8.3 per product. On PubMed, 24.8% of supplements had data showing an increase in T with supplementation, 10.1% had data showing a decrease in T, and 18.3% had data showing no change in T. No data were found on 61.5% of supplements on their effect on T. Supplements contained a median 1,291% of the RDA for vitamin B12, 807.6% for vitamin B6, 272% of zinc, 200% of vitamin B5, and 187.5% of vitamin B3. Thirteen products exceeded the US Food and Drug Administration UL of ingredients (zinc, vitamin B3, and magnesium).CONCLUSIONS: Ninety percent of “T booster” supplements claimed to boost T. However, only 24.8% of these had data to support these claims. A total of 10.1% contained components with data suggesting a negative effect on T. Many had supra-therapeutic doses of vitamins and minerals, occasionally over the UL. Patients should be informed that “T booster” supplements may not have ingredients to support their claims.]]>

Benign prostatic hyperplasia (BPH) is an age-related disease of unknown etiology, characterized by prostatic enlargement coincident with distinct alterations in tissue histology. In the present study, we investigated whether triptolide can prevent testosterone-induced prostatic hyperplasia in rats. Castration was performed via the scrotal route after urethane aesthesia. BPH was induced in experimental groups by daily subcutaneous injections of testosterone propionate (TP) for two weeks. Triptolide was administered daily by oral gavage at a dose of 100 and 50 μg·kg for 2 weeks, along with the TP injections. On day 14, the animals were humanely killed by cervical dislocation after aesthesia. Prostates were excised, weighed, and used for histological studies. Testosterone and dihydrotestosterone (DHT) levels in serum and prostate were measured. The results showed that triptolide significantly reduced the prostate weight, and the testosterone and DHT levels in both the serum and prostate. Histopathological examination also showed that triptolide treatment suppressed TP-induced prostatic hyperplasia. In conclusion, triptolide effectively inhibits the development of BPH induced by testosterone in a rat model.

Objective: To evaluate the effects of Testosterone Undecanoate Pills (TUP) on insulin resistance (IR) in type-2 diabetes men with hypogonadism. METHODS: We randomly divided 82 type-2 diabetes patients with hypogonadism into a treatment (n = 42) and a control group (n = 40), both maintaining their glucose- and lipid-reducing therapies, while the former treated orally with TUP in addition. After 6 months of medication, we compared the body mass index (BMI), waist circumference (WC), blood glucose level, HbA1c, lipid profile, IR index obtained by homeostatic model assessment (HOMA-IR), insulin sensitivity index (ISI), sex hormone levels, and sexual function scores between the two groups of patients. RESULTS: Compared with the baseline, the patients in the treatment group showed significant decreases after medication in BMI (［26.71 ± 2.39］ vs ［25.15 ± 2.28］ kg/m2, P <0.05), WC (［89.96 ± 9.13］ vs ［85.03 ± 9.58］ cm, P <0.05), HbA1C (［7.73 ± 1.31］ vs ［7.01 ± 1.25］ %, P <0.05), and triglyeride (［1.97 ± 0.83］ vs ［1.41 ± 0.69］ mmol/L, P <0.05), a markedly elevated level of total testosterone (［7.16 ± 2.21］ vs ［14.22 ± 2.63］ nmol/L, P <0.05), and remarkable improvement in HOMA-IR (3.76 ± 1.18 vs 2.55 ± 1.03, P <0.05), ISI (96 ± 51 vs 138 ± 53, P <0.05) and total scores of the Aging Males' Symptoms (P <0.05). But no significant changes were observed in the scores of the International Index of Erectile Function (IIEF) after treatment (13.28 ± 6.38 vs 14.95 ± 6.08, P >0.05). CONCLUSIONS TUP can significantly improve insulin resistance in type-2 diabetes men with hypogonadism.

Objective: To investigate the clinical effects of oral Testosterone Undecanoate Capsules (TUC) combined with Qilin Pills (QLP) on late-onset hypogonadism (LOH) in men. METHODS: Sixty-three LOH patients meeting the inclusion criteria were randomly divided into a control group (aged ［48.4 ± 6.2］ yr, n = 32) and an experimental group (aged ［47.2 ± 5.6］ yr, n = 31) to be treated with oral TUC (80 mg, qd) and TUC + QLP (6g, tid), respectively, both for 3 months. Comparisons were made between the two groups of patients in the IIEF-5 scores, total testosterone (TT) levels, and scores in the Aging Males' Symptoms (AMS) scale before and after treatment. RESULTS: After treatment, the patients of the experimental group, as compared with the controls, showed a significantly increased IIEF-5 score (21.7 ± 5.8 vs 15.9 ± 4.7, P <0.05) and TT level (［16.7 ± 2.2］ vs ［13.1 ± 2.8］ nmol/L, P <0.05), but a decreased AMS score (20.7 ± 5.7 vs 31.3±6.5, P <0.05). CONCLUSIONS TUC combined with Qilin Pills has a better effect and a lower rate of adverse reactions than TUC used alone in the treatment of late-onset hypogonadism in males.

Objective: To explore the effects of Kudzu Root plus Cinnamon Granules (KR+C) on prostatic hyperplasia (PH) in mice. METHODS: Sixty 4-week-old Kunming male mice were randomly divided into six groups: blank control, PH model, high-, medium- and low-dose KR+C, and finasteride control. All the mice except those in the blank control group were subcutaneously injected with testosterone propionate (5 mg / ［kg·d］) at 7 days after surgical castration. The animals of different groups were treated intragastrically with different doses of KR+C, finasteride, and normal saline respectively for 3 weeks and then sacrificed for weighing of the prostate, calculation of the prostatic index, observation of the morphological changes in the prostate after HE staining, determination of the expressions of FGF2, Ki67 and TGF-β1 by immunohistochemistry, detection of 5α-reductase activity by ELISA, and measurement of the apoptosis index of the prostatic cells by TUNEL. RESULTS: Compared with the model controls, the mice of the other groups showed significantly reduced prostatic volume (P <0.05), prostatic index (P <0.05), expressions of FGF2, Ki67 and TGF-β1, and activity of 5 α-reductase (P <0.05), but remarkably increased apoptosis index of the prostatic cells (P <0.05). However, no statistically significant differences were observed in the above parameters between the finasteride control and the three KR+C groups (P>0.05). CONCLUSIONS KR+C can reduce the prostatic volume of PH mice by decreasing the activity of 5α- reductase, inhibiting the expressions of FGF2, Ki67 and TGF-β1, and promoting the apoptosis of prostatic cells.

Objective: To investigate whether androgens can regulate the expression of eNOS in rat corpus cavernosum through AKT3, PIK3CA, CALM, and CAV1 and influence erectile function. METHODS: Thirty-six 8-week-old male SD rats were randomly divided into groups A (4-week control), B (6-week control), C (4-week castration), D (6-week castration), E (4-week castration + testosterone replacement), and F (6-week castration + testosterone replacement). Both the testis and epididymis were removed from the rats in groups C, D, E and F, and on the second day after surgery, the animals of groups E and F were subcutaneously injected with testosterone propionate at 3 mg per kg of the body weight qd alt while all the others with isodose oil instead. At 4 weeks (for groups A, C and E) and 6 weeks (for groups B, D and F) after treatment, we detected the maximum intracavernous pressure (ICPmax), the mean carotid arterial pressure (MAP) and their ratio (ICPmax/MAP), measured the level of serum testosterone (T), and determined the expressions of eNOS, P-eNOS, AKT3, PIK3CA, CALM and CAV1 in the corpus cavernosum by Western blot and immunohistochemistry. RESULTS: No statistically significant differences were observed in the body weight and MAP among different groups. The serum T level and ICPmax/MAP were remarkably lower in groups C and D than in the other four groups (P<0.01) as well as in groups E and F than in A and B (P<0.05) but exhibited no significant differences either between E and F or between A and B. Immunohistochemistry showed that eNOS and P-eNOS were mainly expressed in the vascular endothelial cell membrane and cavernous vascular lumen, while AKT3, PIK3CA, CALM and CAV1 chiefly in the vascular endothelial cell cytoplasm and membrane, with a few in the smooth muscle cells. Western blot analysis manifested that the expressions of eNOS, P-eNOS, AKT3, PIK3CA, CALM and CAV1 were markedly lower in groups C and D than in A, B, E and F (P<0.01) as well as in D than in C (P<0.05) but those in groups E and F did not showed any significant difference from those in A and B, nor E from F or A from B. CONCLUSIONS Androgens can improve erectile function by upregulating the expressions of AKT3, PIK3CA, CALM and CAV1 protein molecules and activating eNOS after its phosphorylation, though the exact molecular mechanisms are yet to be further studied.

Objective: To investigate the expression characteristics of the USP24 gene in the mouse testis and its role in spermatogenesis. METHODS: We examined the expression characteristics of USP24 in the testis tissues of wild-type mice at different postnatal weeks (PNW) and androgen receptor (AR)-knockout (ARKO) adult mice using real-time quantitative PCR and immunofluorescence, and detected the transcriptional activity of the USP24 promoter by dual-luciferase reporter gene assay. RESULTS: The expression of the USP24 gene was low in the testis tissue of the wild-type mice at PNW 1, increased dramatically at PNW 3 and stayed at a similar level till PNW 8. The USP24 protein was located mainly in the cytoplasm of Sertoli and spermatogenic cells. Compared with the wild-type, the adult ARKO mice showed a decreased expression of USP24 localized in the posterior head and mid-piece of the mature sperm in the testis. Dual-luciferase reporter gene assay showed that the transcriptional activity of the USP24 promoter was increased after testosterone stimulation. CONCLUSIONS The increased expression of the USP24 gene was associated with the initiation of sexual development, and the USP24 protein was expressed in the mature sperm of the mice. USP24 is an AR-target gene, which may be involved in the regulation of spermatogenesis in mice.
