Therapeutic effect of Jinghuosu on oligospermia and asthenospermia / 中华男科学杂志

Objective@#To investigate the effects of the compound preparation Jinghuosu on oligospermia and asthenospermia.@*METHODS@#This multi-centered clinical study included 120 cases of mild to moderate idiopathic oligospermia or asthenospermia, all treated with oral Jinghuosu once a bag, bid, for 3 successive months. Before and at 1, 2 and 3 months after treatment, we detected sperm concentration, total sperm motility, progressive sperm motility and normal sperm morphology of each ejaculate, and recorded whether the patients had any adverse reactions.@*RESULTS@#After 3 months of treatment, all the patients showed obvious improvement in semen parameters, most significantly in sperm concentration, total sperm motility, and the percentages of progressive motile sperm and morphologically normal sperm (P <0.05). No significant adverse reactions were observed during the 3 months of medication.@*CONCLUSIONS@#Jinghuosu has a significant efficacy and no obvious adverse effect in the treatment of mild to moderate oligospermia and asthenospermia.

Safety and efficacy of L-carnitine and tadalafil for late-onset hypogonadism with ED: a randomized controlled multicenter clinical trial / 中华男科学杂志

<p><b>OBJECTIVE</b>To evaluate the safety and effect of L-carnitine combined with tadalafil in the treatment of late-onset hypogonadism (LOH) with erectile dysfunction (ED).</p><p><b>METHODS</b>We randomly divided 140 cases of LOH with ED aged 40 -70 years into a treatment and a control group to receive L-carnitine + tadalafil and testosterone undecanoate + tadalafil, respectively. After 8 weeks of treatment, we obtained the scores on IIEF-5 and Aging Male Symptoms (AMS), observed changes in the levels of sex hormones, analyzed the results of the routine blood test and PSA level, and evaluated the safety of medication.</p><p><b>RESULTS</b>Finally, 110 cases were included, 60 in the treatment group and 50 in the control. After 8 weeks of medication, the IIEF-5 and AMS scores were significantly improved as compared with the baseline both in the treatment group (17.7 +/- 3.5 vs 10.2 +/- 2.7 and 36.2 +/- 6.5 vs 48.8 +/- 5.8) and in the control group (16.7 +/- 2.6 vs 9.3 +/- 2.4 and 35.8 +/- 6.6 vs 50.7 +/- 5.0) (both P < 0.05), with no significant differences between the two groups (P > 0.05). As for the safety of medication, there were no significant differences between the two groups before and after treatment (P > 0.05). Two patients in the control group showed a PSA level > 4 microg/L, which was confirmed to be caused by prostatitis during follow-up.</p><p><b>CONCLUSION</b>L-carnitine combined with tadalafil is safe and effective for the treatment of LOH with ED.</p>

Efficacy of natural vitamin E on oligospermia and asthenospermia: a prospective multi-centered randomized controlled study of 106 cases / 中华男科学杂志

<p><b>OBJECTIVE</b>To explore the therapeutic effect of natural vitamin E (VitE) on oligospermia and asthenospermia in in- fertile men.</p><p><b>METHODS</b>We conducted a prospective multi-centered randomized controlled study on 64 infertile men with oligospermia (31 as controls treated with Tamoxifen 10 mg bid and 33 as experimental cases treated with Tamoxifen 10 mg bid + VitE 100 mg tid) and 42 cases of asthenospermia (20 as controls treated with Levocarnitine oral solution 1 bottle bid and 22 as experimental cases treated with Levocarnitine oral solution 1 bottle bid + VitE 100 mg tid). We compared the control and experimental groups in sperm concentration and percentage of progressively motile sperm before and 3 months after medication, as well as the rate of clinical pregnancy and adverse events.</p><p><b>RESULTS</b>Among the oligospermia patients, the average sperm concentrations in the control and experimental groups were 8.00 x 10(6)/ml and 10.66 x 10(6)/ml before medication (P > 0.05). After medication, the numbers of cases evaluated as with no, slight, moderate and marked improvement in sperm concentration were 10 and 9 (P > 0.05), 16 and 14 (P > 0.05), 5 and 4 (P > 0.05) and 0 and 0 (P >0.05); and the numbers of natural pregnancies were 0 and 6 in the control and experimental groups (P < 0.01). Among the asthenospermia patients, the average rates of progressively motile sperm were 17.00% and 18.10% in the control and experimental groups before medication (P > 0.05). After medication, the numbers of cases evaluated as with no, slight, moderate and marked improvement in the percentage of progressively motile sperm were 7 and 2 (P < 0.01), 4 and 8 (P < 0.01), 3 and 2 (P > 0.05) and 1 and 1 (P > 0.05), and the numbers of natural pregnancies were 5 and 9 in the two groups (P < 0.01), but no adverse events were observed.</p><p><b>CONCLUSION</b>As a safe and effective adjuvant agent for the treatment of oligospermia and asthenospermia, vitamin E can improve sperm concentration, the percentage of progressively motile sperm, and finally the rate of natural pregnancy.</p>

Application of quantitative temperature testing in diagnosis of neurogenic erectile dysfunction / 法医学杂志

OBJECTIVE@#To explore the application of quantitative temperature testing (QTT) in forensic identification and clinical diagnosis of neurogenic erectile dysfunction (NED).@*METHODS@#TSA-II-NeuroSensory Analyzer was used to measure the thresholds of four kinds of sensory, including cold, cold pain, heat, heat pain, in 22 normal and 35 NED patients at dorsal glans (DG), left thigh interior (LTI) and left thenar (LT). To calculate the relative thresholds of the sensory mentioned above between DG and LTI (DG/LTI), and between DG and LT (DG/LT). Then to analyze those thresholds and the relative thresholds.@*RESULTS@#NED group showed significant higher threshold than the normal group in DG-heat, DG-heat pain, LTI-heat, LTI-heat pain, DG/LTI-heat, DG/LT-heat, DG/LT-heat pain (P < 0.05).@*CONCLUSION@#The threshold of QTT at dorsal glans could be used as an accessory indicator in forensic medicine and clinical diagnosis of NED.

Assisted reproductive technology in the treatment of male infertility: potential risks and tactics / 中华男科学杂志

Assisted reproductive technology (ART), developed in the end of last century, has been playing an irreplaceable role in the treatment of male infertility, though it does have its potential risks, including the induction of monozygotic twins, premature delivery, high incidence of birth defects, etc. How to avoid these risks has posed a challenge and demands earnest attention from andrologists. This article summarizes the main potential risks of ART and proposes some tactics concerning patient evaluation, health education and treatment standardization, so as to optimize the outcomes and minimize the risks. Meanwhile, emphasis is placed on the importance of etiological and anti-oxidant strategies in the treatment of male infertility.

Strontium-89: a desirable therapeutic for bone metastases of prostate cancer / 中华男科学杂志

<p><b>OBJECTIVE</b>To evaluate the efficacy of strontium-89 (89Sr) in the treatment of painful bone metastases of prostate cancer.</p><p><b>METHODS</b>A total of 116 patients with painful bone metastases of prostate cancer received bilateral orchiectomy and incretion, followed by intravenous injection of 89Sr at the dose of 1.48-2.22 MBq (40-60 microCi)/kg. The clinical effects were evaluated by follow-up analysis.</p><p><b>RESULTS</b>After the 89Sr treatment, appetite and sleep were evidently improved in 33.6% and 56.0% of the patients respectively, the applied dose of anodyne reduced in 61.2%, pain alleviated in 83.6%, with an absolute palliation rate of 24.1%. Pain relief started at 3-21 (10.2 +/- 6.5) days and lasted 3-12 (5.3 +/- 2.2) months. Flare ache occurred in 31.9% of the patients. Compared with pre-treatment, the mean score on Karnofsky's performance status (KPS) was 20.0% higher, and the WBC count decreased to 3.0-3.9 x 10(6)/L in 18.1% of the patients. Whole body bone scintigraphy of 53 followed-up patients showed that 39 (73.6%) of them exhibited an obvious decrease in the number of metastases, 10 (18.9% remained in a stabilized state and only 4 (7.5% deteriorated.</p><p><b>CONCLUSION</b>89Sr, capable of inhibiting bone metastasis, palliating pain and improving the quality of life with few adverse effects, can be used as a desirable therapeutic for painful bone metastases of prostate cancer.</p>
