RESUMO
OBJECTIVE: To study the effect of the traditional Chinese therapy of tonifying the kidney and invigorating blood circulation (TKIB) on male infertility. METHODS: Forty-two infertile males with abnormal DNA fragmentation index (DFI) were randomly allocated into a TKIB (n = 22) and a control group (n = 20), the former treated by TKIB with an oral Chinese medicinal prescription while the latter with oral tamoxifen tablets and vitamin E capsules, both for 3 months. Before and after treatment, we obtained the semen parameters and sperm DFI from the patients and followed them up for the outcomes of natural pregnancy. RESULTS: Compared with the baseline, the patients in both the TKIB and control groups showed significant increases after medication in sperm concentration (ï¼»36.82 ± 29.16ï¼½ and ï¼»34.56 ± 37.03ï¼½ vs ï¼»50.00 ± 39.16ï¼½ and ï¼»40.72 ± 47.37ï¼½ ×106/ml, P<0.05), the percentage of progressively motile sperm (PMS) (ï¼»20.62 ± 9.10ï¼½% and ï¼»21.25 ± 9.11ï¼½% vs ï¼»36.82 ± 13.45ï¼½% and ï¼»26.18 ± 10.60ï¼½%, P<0.05) and the percentage of morphologically normal sperm (MNS) (ï¼»1.28 ± 1.00ï¼½% and ï¼»1.48 ± 0.91ï¼½% vs ï¼»3.44 ± 1.33ï¼½% and ï¼»2.57 ± 1.32ï¼½%, P<0.05), but remarkably decreased sperm DFI (ï¼»29.07 ± 11.52ï¼½% and ï¼»24.43 ± 8.46ï¼½% vs ï¼»15.51 ± 11.31ï¼½% and ï¼»18.53 ± 10.44ï¼½%, P<0.05). The patients of the TKIB group exhibited an even higher total sperm motility and percentages of PMS and MNS than those of the control group (P<0.05) but no statistically significant difference from the latter in sperm concentration or DFI (P>0.05). Besides, the former achieved higher rates of natural pregnancy (18.2%) and live birth (18.2%) than the controls (15% and 10%) though neither with statistically significant difference (P>0.05). CONCLUSIONS: The traditional Chinese therapy of tonifying the kidney and invigorating blood circulation can reduce sperm DNA damage and improve the outcomes of natural pregnancy in infertile men.

Male infertility (MI) is a complex multifactorial disease, and idiopathic infertility accounts for 30% of cases of MI. At present, the evidence for the effectiveness of empirical drugs is limited, and in vitro fertilization is costly and may increase the risk of birth defects and childhood cancers. Therefore, affected individuals may feel obliged to pursue natural remedies. Traditional Chinese medicine (TCM) may represent a useful option for infertile men. It has been demonstrated that TCM can regulate the hypothalamic-pituitary-testicular axis and boost the function of Sertoli cells and Leydig cells. TCM can also alleviate inflammation, prevent oxidative stress, reduce the DNA fragmentation index, and modulate the proliferation and apoptosis of germ cells. Furthermore, TCM can supply trace elements and vitamins, ameliorate the microcirculation of the testis, decrease the levels of serum anti-sperm antibody, and modify epigenetic markers. However, the evidence in favor of TCM is not compelling, which has hindered the development of TCM. This review attempts to elucidate the underlying therapeutic mechanisms of TCM. We also explore the advantages of TCM, differences between TCM and Western medicine, and problems in existing studies. Subsequently, we propose solutions to these problems and present perspectives for the future development of TCM.
RESUMO
OBJECTIVE: To investigate the antioxidative and spermatogenesis-repairing effects of Shenjing Guben Pills (SGP), a Chinese medicine for invigorating the kidney and blood circulation, on the testis, epididymis and sperm in rats with oxidative stress injury (OSI) induced by cadmium chloride. METHODS: Seventy-two male Wistar rats were equally randomized into six groups: normal control, OSI model control, Wuzi Yanzong Pills (WYP) and low-, medium- and high-dose SGP. The OSI model was made in the latter five groups by intraperitoneal injection of cadmium chloride at 1 mg/kg, and 24 hours later, the rats of the normal and model control groups treated intragastrically with 0.9% normal saline, those of the WYP group with WYP at 4.5 g/kg/d, and those of the low-, medium- and high-dose SGP groups with SGP at 2.8, 5.6 and 11.2 g/kg/d, respectively, all for 56 days. Then, all the animals were sacrificed for obtainment of the visceral indexes and histopathological changes of the testis, epididymis and seminal vesicle, measurement of sperm concentration and motility and the percentage of morphologically normal sperm (MNS) in the epididymis, and determination of the levels of glutathione perox-idase (GSH-PX), superoxide dismutase (SOD), malondial-dehyde aldehyde (MDA) and serum testosterone (T). RESULTS: Compared with the OSI model controls, the rats in the high-, medium- and low-dose SGP groups showed significantly higher visceral indexes of the testis (ï¼»0.237 ± 0.098ï¼½ vs ï¼»0.403 ± 0.090ï¼½, ï¼»0.357 ± 0.150ï¼½ and ï¼»0.348 ± 0.140ï¼½ g/100 g, P < 0.05) and seminal vesicle (ï¼»0.241 ± 0.118ï¼½ vs ï¼»0.347 ± 0.115ï¼½, ï¼»0.336 ± 0.090ï¼½ and ï¼»0.320 ± 0.065ï¼½ g/100 g, P < 0.05) and those of the high-dose SGP group in the epididymal index (ï¼»0.099 ± 0.088ï¼½ vs ï¼»0.156 ± 0.030ï¼½ g/100 g, P < 0.05). In comparison with the OSI model controls, the animals of the high-, medium- and low-dose SGP groups exhibited significant increases in sperm concentration (ï¼»10.5 ± 17.7ï¼½ vs ï¼»58.1 ± 32.2ï¼½, ï¼»36.0 ± 36.2ï¼½ and ï¼»31.9 ± 32.7ï¼½ ×106/ml, P < 0.05) and serum T (ï¼»2.56 ± 0.75ï¼½ vs ï¼»3.62 ± 0.96ï¼½, ï¼»3.48 ± 1.33ï¼½ and ï¼»3.24 ± 0.83ï¼½ nmol/L, P < 0.05 or P < 0.01), and those of the high- and medium-dose SCG groups in total sperm motility (ï¼»9.5 ± 13.0ï¼½% vs ï¼»26.5 ± 15.5ï¼½% and ï¼»18.9 ± 8.2ï¼½%, P < 0.05) and MNS (ï¼»36.2 ± 40.2ï¼½% vs ï¼»85.3 ± 23.3ï¼½% and ï¼»65.8 ± 28.1ï¼½%, P < 0.05) and the levels GSH-PX (ï¼»3.62 ± 2.22ï¼½ vs ï¼»5.70 ± 1.73ï¼½ and ï¼»5.42 ± 2.35ï¼½ U/mg prot, P < 0.05 ) and SOD (ï¼»41.3 ± 8.8ï¼½ vs ï¼»52.7 ± 14.6ï¼½ and ï¼»51.3 ± 14.7ï¼½ U/mg prot, P < 0.05). The MDA level, however, was markedly decreased in the high-, medium- and low-dose SGP groups (ï¼»0.41 ± 0.29ï¼½, ï¼»0.44 ± 0.19ï¼½ and ï¼»0.47 ± 0.20ï¼½ nmol/mg prot) as compared with that in the OSI model controls (ï¼»0.69 ± 0.28ï¼½ nmol/mg prot) (P < 0.05). Histopathological examinations manifested coagulative necrosis, calcification and disappearance of spermatogenic and Sertoli cells in the seminiferous tubules of the OSI model controls, with decreased intraluminal secretions and atrophic epithelial papillae in the seminal vesicles and non-sperm cells in the narrowed lumens of the atrophic epididymis. With the increased dose of SGP, the proportion of normal seminiferous tubules was enlarged, the epithelia of the seminal vesicle became column-shaped again, and the epididymal lumens grew lager with more sperm cells, which indicated a dose-dependent therapeutic efficacy. Medium- and high-dose SGP achieved a significantly better effect than WYP. CONCLUSIONS: Shenjing Guben Pills can antagonize oxidative stress, elevate the levels of testicular antioxidant enzymes and serum T, repair pathological injury of the testis, epididymis and seminal vesicle, and improve semen quality and spermatogenic function.

OBJECTIVE: To evaluate the clinical efficacy and safety of Qilin Pills in the treatment of oligoasthenospermia in infertile men. METHODS: This multi-centered randomized double-blind controlled clinical trial included 216 infertile males with oligoasthenospermia, 108 in the trial group and the other 108 in the control, the former treated with Qilin Pills at the dose of 6 g tid while the latter with Wuziyanzong Pills at 6 g bid, both for 12 weeks. We examined the total sperm count, sperm motility and the count of progressively motile sperm of the patients before and at 4, 8 and 12 weeks after medication and evaluated the safety of the drug based on the adverse events and the laboratory results of blood and urine routine examinations and liver and kidney function tests. RESULTS: Compared with the baseline, the patients in the trial group showed a significant time-dependent improvement after 4, 8 and 12 weeks of medication in sperm motility (21.75% vs 27.54%, 29.04% and 32.95%, P <0.05), total sperm count (156.27 ×106 vs 177.33, 188.18 and 205.44 ×106, P <0.05), and the count of progressively motile sperm (32.08 ×106/ml vs 46.33, 50.98 and 61.10 ×106/ml, P <0.05). The three parameters above were also improved in the controls, but more significantly in the trial group (P <0.05). CONCLUSIONS: Qilin Pills can evidently improve the semen quality of oligoasthenospermia patients with no obvious adverse events.

OBJECTIVE: To objectively evaluate the efficacy and safety of Yimusake Tablet in the treatment of premature ejaculation (PE) through a multi-centered large-sample trial. METHODS: We conducted a multi-centered, open, fixed-dose, and self-compared clinical trial among 300 patients with diagnosed PE. The trial lasted 12 weeks, including 4 weeks without any medication and 8 weeks of treatment with Yimusake Tablet, 2 pills (1 g) per night. We observed the intravaginal ejaculation latency time (IELT) before and after treatment, evaluated the safety of medication, and performed a questionnaire investigation on the patients' satisfaction. RESULTS: Of the 300 PE patients, 288 accomplished the clinical trial. The patients ranged in age from 22 to 60 years, averaging at 31.6 years. The mean IELT of the patient was 62.5 seconds at baseline, 168.9 seconds after 4 weeks of treatment with Yimusake Tablet, and 222.2 seconds after 8 weeks of medication. Among the 157 patients with normal erectile function (IIEF >21), the mean IELT was 71.4 seconds before treatment, 147.4 seconds after 4 weeks of medication, and 172.5 seconds after 8 weeks of medication. The patients' satisfaction was significantly increased after treatment. Those complicated by mild to moderate erectile dysfunction achieved different degrees of improvement in the IIEF-5 score, with a mean increase of 3.8. Only a few patients experienced mild adverse events, including constipation, dry mouth, nose bleeding, abdominal pain, and lumbosacral pain, which were all relieved without drug withdrawal. CONCLUSION: Yimusake Tablet is a safe and effective medicine for the treatment of PE.

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.

OBJECTIVE: To investigate the effects of Compound Xuanju Capsule on the levels of sex hormones and the weight of sexual organs in castrated male rats. METHODS: A randomized model control trail was performed in 60 young male SD rats of SPF grade, of which 12 were included in the normal control group, and the others were castrated and randomly divided into a model control group and a high-dose, a median-dose and a low-dose Xuanju group. The control groups received intragastric administration of normal saline, and the model groups solution of Compound Xuanju Capsule, all for 20 days. Then we determined by radioimmunoassay the levels of testosterone (T), luteinizing hormone (LH) and follicle stimulating hormone (FSH) in the peripheral blood of the rats, and measured the weights of the epididymis, preputial gland, seminal vesicle, prostate and levator ani muscle. RESULTS: The T levels were remarkably lower in the castrated groups than in the normal controls, and significantly higher in the three Xuanju groups than in the model controls (P < 0.01). Both LH and FSH levels were increased in the model control and Xuanju groups as compared with the normal control group, the former with statistically significant difference (P < 0.05) and the latter without. In comparison with the normal controls, the model control rats showed a marked reduction in the indexes of the preputial gland, seminal vesicle, prostate and levator ani muscle, and the high-dose Xuanju group exhibited a significant increase in the seminal vesicle index as compared with the model controls (P < 0.05). There were no statistically significant differences in the indexes of preputial gland, prostate and levator ani muscle among different dose groups (P > 0.05). CONCLUSION: Compound Xuanju Capsule can elevate T and LH levels in the peripheral blood of male SD rats and improve the indexes of their sex organs, which may be an important mechanism behind its effect on ED.

OBJECTIVE: To investigate the efficacy and possible action mechanism of Qianlie Beixi Capsules in the treatment of unliquefiable semen. METHODS: A total of 190 patients with unliquefiable semen were treated with Qianlie Beixi Capsules for 1 or 2 courses (3 weeks per a course). The seminal changes were observed and recorded. RESULTS: Of the 190 patients in the 1-course treatment arm, 99 were cured and 91 failed to respond after the first course. And the effectiveness rate was 52.1%. Of the 122 patients in the 2-course treatment arm, 81 were cured and 41 failed to respond after the second course. And the effectiveness rate was 66.4%. The efficacy of 2-course regimen was obviously better than that of 1-course regiment. In the meantime, sperm density improved in the 2-course treatment arm. Sperm motility improved slightly in the effective subjects of 1-course treatment arm. All the above results had statistically significant differences (P < 0.05). CONCLUSION: Qianlie Beixi Capsules is both safe and effective for unliquefiable semen and may shorten the time of seminal liquefaction.

OBJECTIVE: To observe the efficacy of Qilin Pills in the treatment of oligoasthenospermia. METHODS: We conducted a multi-centered open controlled clinical trial by including 220 oligoasthenospermia patients in a trial group and another 110 as controls. The patients in the trial group were treated with Qilin Pills at the dose of 6 g tid, and the controls given Wuziyanzong Pills at 6 g bid, both for a course of 12 weeks. Then we evaluated the clinical effects of Qilin Pills with sperm concentration, the numbers of grade a and grade a + b sperm, and sperm motility as the primary, and the pregnancy rate of the patients'spouses as the secondary therapeutic indexes. RESULTS: A total of 310 patients accomplished the clinical trial, 208 in the trial and 102 in the control group. Compared with the baseline, significant improvement was observed in the semen parameters after 4, 8 and 12 weeks of treatment in both the trial and control groups except sperm density and the number of grade a sperm in the control after 4 weeks (P < 0.01), and the improvement was even more significant in all the semen parameters at the same time points in the trial than in the control group (P < 0.01). CONCLUSION: Qilin Pills can evidently improve the seminal quality of oligoasthenospermia patients with no obvious adverse events.
