Benign prostatic hyperplasia (BPH) is a chronic male disease characterized by the enlarged prostate. Celtis chosenianaNakai (C. choseniana) is medicinally used to alleviate pain, gastric disease, and lung abscess. In this study, the effect of C. choseniana extract on BPH was investigated using testosterone-induced rats. Sprague Dawley rats were divided into five groups: control, BPH (testosterone 5 mg·kg-1), Fina (finasteride 2 mg·kg-1), and C. choseniana (50 and 100 mg·kg-1). After four weeks of TP treatment with finasteride or C. choseniana, prostate weights and DHT levels were measured. In addition, the prostates were histopathologically examined and measured for protein kinase B (Akt)/nuclear factor-κB (NF-κB)/AR signaling, proliferation, apoptosis, and autophagy. Prostate weight and epithelial thickness were reduced in the C. choseniana groups compared with that in the BPH group. The extract of C. choseniana acted as a 5α reductase inhibitor, reducing DHT levels in the prostate. Furthermore, the extract of C. choseniana blocked the activation of p-Akt, nuclear NF-κB activation and reduced the expression of AR and PSA compared with BPH. Moreover, the expression of Bax, PARP-1, and p53 increased, while the expression of bcl-2 decreased. The present study demonstrated that C. choseniana extract alleviated testosterone-induced BPH by suppressing 5α reductase and Akt/NF-κB activation, reducing AR signaling and inducing apoptosis and autophagy in the prostate. These results suggested that C. choseniana probably contain potential herbal agents to alleviate BPH.

OBJECTIVE:
To determine the mitigating effects of sodium 4-phenylbutyrate (4-PBA) on high-fat diet (HFD)-induced spermatogenesis dysfunction.
METHODS:
Male rats (n = 30) were randomly divided into three groups: control, HFD, and 4-PBA (HFD +4-PBA). After 13 weeks, rats were euthanized. Testes and epididymis were harvested for further analysis. Sex hormones were detected, and hematoxylin and eosin staining was performed to examine the histological changes in the testes. Semen samples were collected to evaluate sperm quality. Spermatogenic cell apoptosis was detected by TUNEL assay.
RESULTS:
Compared with the control group, the final body weight and body weight gain were significantly higher in HFD-fed rats, while the testicle/body weight ratios were lower (P < 0.05). In HFD-fed rats, obvious pathological changes in the testicular tissue were observed. Treatment with 4-PBA attenuated HFD-induced histological damage, ameliorated the HFD-induced decrease in serum testosterone (T), and reduced the rate of testicular cell apoptosis (P < 0.05) in obese male rats. Finally, 4-PBA significantly improved semen parameters in HFD rats (P < 0.05).
CONCLUSION
HFD exposure induced detrimental effects on spermatogenesis, semen quality, serum T level, and testicular cell apoptosis in rats. Treatment with 4-PBA ameliorated HFD?induced impaired spermatogenesis via inhibition of apop-tosis in rats. 4-PBA may have therapeutic value in the treatment of obesity?related impairment of spermatogenesis.

OBJECTIVE:
To study the effect of 6-week intensive training on renal function in rats and the mechanism of exercise-induced proteinuria.
METHODS:
Thirty-six male SD rats, aged 6 weeks, were divided into two groups, including a control group(C,=12)and an overtraining group(M,=24). After the rats adapted to feeding for 4 d, group C did not carry out any exercise, and the M group did 6-week of increasing load swimming, 6 days a week, once a day. Started with the load of 1%weight at the beginning of the 4 week,and gradually increased (to 6% weight). Took a single urine from both groups 30 min after the end of the training. Blood was taken from the main ventral vein, and the bilateral kidneys were to be tested. The levels of tested urine protein, microalbumin and neutrophil gelatinase associated lipocalin(NGAL) was determined by using enzyme linked immunosorbent assaytest. The content of urine creatinine was tested with alkaline picric acid method,. The serum levels of colorimetric method to determine serum creatinine and urea nitrogen were determined by colorimetric method. The expression of Nephrin in renal tissue was detected by Western blot and the radioimmunoassay was used to test serum testosterone, corticosterone and renin-angiotensin system related index.
RESULTS:
Compared with group C, the serum testosterone/cortisone(T/C) of group M was decreased significantly (<0.01). The urine total protein(TP), microalbumin (mAlb), microalbumin/creatinine (mAlb/CRE), NGAL, blood urea nitrogen (BUN) and serum creatinine(SCr) were increased significantly (<0.01). The abnormality of glomerular structure was obvious, and the paller scores were higher. The protein expression of Nephrin was obviously down decreased (<0.01). The renin activity (Ra) and angiotension Ⅱ (Ang Ⅱ) in renal and circulating blood were decreased significantly (<0.01).
CONCLUSIONS
The effects of 6-week intensive training on renal function in rats and the mechanism of exercise-induced proteinuria may be that overtraining can induce the continuous excitation of Reninrenin activity in renal and circulating blood, down-regulated the expression of Nephrin, lead to abnormality of renal structure and function, and proteinuria.

A variety of methods for testosterone replacement therapy (TRT) exist, and the major potential risks of TRT have been well established. The risk of developing polycythemia secondary to exogenous testosterone (T) has been reported to range from 0.4% to 40%. Implantable T pellets have been used since 1972, and secondary polycythemia has been reported to be as low as 0.4% with this administration modality. However, our experience has suggested a higher rate. We conducted an institutional review board-approved, single-institution, retrospective chart review (2009-2013) to determine the rate of secondary polycythemia in 228 men treated with subcutaneously implanted testosterone pellets. Kaplan-Meyer failure curves were used to estimate time until the development of polycythemia (hematocrit >50%). The mean number of pellets administered was 12 (range: 6-16). The mean follow-up was 566 days. The median time to development of polycythemia whereby 50% of patients developed polycythemia was 50 months. The estimated rate of polycythemia at 6 months was 10.4%, 12 months was 17.3%, and 24 months was 30.2%. We concluded that the incidence of secondary polycythemia while on T pellet therapy may be higher than previously established.

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.

National Journal of Andrology 2017;23(9):842-847
Klinefelter's syndrome (KS) is a most frequent sex chromosomal disorder in males, which is characterized by hypogonadism and infertility. The development of assisted reproductive technology has made it possible for KS males to father children. Microdissection testicular sperm extraction (mTESE) is widely considered to be the best method for sperm retrieval in KS patients. This article presents an overview on mTESE for men with non-mosaic KS in the aspects of its predictors, sperm retrieval rate, operation procedure, preoperative hormonal therapy, and postoperative complications and testosterone reduction.

Objective:
To investigate the clinical effects of aripiprazole on sexual dysfunction induced by amisulpride or risperidone in male patients with schizophrenia.
METHODS:
This study included 75 male patients with drug-induced secondary sexual dysfunction after treated with amisulpride or risperidone for first-episode schizophrenia between October 2014 and October 2016. We substituted aripiprazole for amisulpride or risperidone, gradually increased the dose from 10 to 30 mg/d within 2 weeks, and maintained 30 mg/d from the 3rd week. At 4 and 8 weeks after medication, we evaluated the sexual function of the patients, measured the levels of serum prolactin (PRL) and testosterone (T), obtained the scores of the Positive and Negative Symptoms Scale (PANSS), recorded adverse reactions, and compared the parameters with those before aripiprazole administration.
RESULTS:
Compared with pre-aripiprazole administration, the patients showed significant increases after 4 weeks of medication in the sexual function score (24.3 ± 2.1 vs 32.6 ± 3.6, P <0.05) and T level ([13.3 ± 2.7] vs [17.4±3.0] mmol/L, P <0.05) but a decreased level of PRL ([38.5 ± 10.5] vs [27.9 ± 8.2] ng/ml, P <0.05). At 8 weeks, the sexual function score and serum PRL were both restored to the baseline levels at admission, and the erectile function score, ejaculation score, total score, and serum T level even exceeded the baseline, though with no statistically significant differences (P >0.05). In comparison with pre-aripiprazole administration, the PANSS score was significantly decreased at 4 weeks after medication (62.1 ± 4.9 vs 57.2 ± 5.5, P <0.05) and even lower at 8 weeks (51.2 ± 5.2) (P <0.05). The incidence rates of medication-related excitation, dizziness, insomnia, and loss of appetite were 6.7%, 5.3%, 4.0% and 1.3% respectively, and no other serious adverse reactions were observed.
CONCLUSIONS
Aripiprazole is effective for the treatment of drug-induced sexual dysfunction in schizophrenic men by continuously alleviating their positive and negative symptoms and meanwhile improving their sexual function and restoring their sexual hormone levels.

OBJECTIVETo evaluate the efficacy and safety of testosterone undecanoate (TU) in the treatment of late-onset hypogonadism (LOH) by meta-analysis.
METHODSWe searched Pubmed (until April 1, 2014), Embase (until March 28, 2014), Cochrane Library (until April 17, 2014), CBM (from January 1, 2001 to February 2, 2014), CNKI (from January 1, 2001 to February 2, 2014), Wanfang Database (from January 1, 2000 to February 2, 2014), and VIP Database (from January 1, 2000 to Febru ary 2, 2014) for randomized controlled trials of TU for the treatment of LOH. We evaluated the quality of the identified literature and performed meta-analysis on the included studies using the Rveman5. 2 software.
RESULTSTotally, 14 studies were included after screening, which involved 1 686 cases. Compared with the placebo and blank control groups, TU treatment significantly increased the levels of serum total testosterone (SMD = 6.22, 95% CI 3.99 to 8.45, P < 0.05) and serum free testosterone (SMD = 4.35, 95% CI 1.86 to 6. 85, P < 0.05) but decreased the contents of luteinizing hormone (WMD = -2.23, 95% CI -4.03 to -0.42, P < 0.05), sex hormone binding globulin (WMD = 2.00, 95% CI 1.38 to 2.63, P < 0.05). TU also remarkably reduced the scores of Partial Androgen Deficiency of the Aging Males (WMD = -9.49, 95% CI -12.96 to -6.03, P < 0.05) and Aging Males Symptoms rating scale (WMD = -2.76, 95% CI -4.85 to -0.66, P <0.05) but increased the hemoglobin level (SMD = 2.35, 95% CI 0.29 to 4.41, P < 0.05) and packed-cell volume (SMD = 4.35, 95% CI 1.36 to 7.33, P < 0.05). However, no significant changes were shown in aspertate aminotransferase, alanine transaminase, prostate-specific antigen, or prostate volume after TU treatment (P > 0.05).
CONCLUSIONTU could significantly increase the serum testosterone level and improve the clinical symptoms of LOH patients without inducing serious adverse reactions. However, due to the limited number and relatively low quality of the included studies, the above conclusion could be cautiously applied to clinical practice.

OBJECTIVETo investigate the effects and mechanisms of diethylhexylphthalate (DEHP) on morphology and function of progenitor Leydig cells (PLC) in rats.
METHODSTwenty pregnant SD rats were randomly divided into 4 groups ( n = 5): normal control group, DEHP low dose group , middle dose group, and high dose group, which were treated from postnatal day (PND) 1 to PND 21 of the pubs with DEHP at the doses of 0, 10, 100, 750 mg/(kg · d) in 0.5 ml of corn oil by gavage respectively. At the end of the treatment, the male pups were killed and blood samples were collected for determination of serum testosterone concentration by chemiluminescence method. The body weight, testis weight and anogenital distance (AGD) were measured. The morphology of PLC was observed by light and transmission electron microscopy. The protein expression of steroidogenic acute regulatory protein(StAR) in PLC was determined by immunohistochemistry. The mRNA expression of insulin-like growth factor-I (IGF-I) in the testis was assayed by real-time PCR.
RESULTSCompared with normal control group, the serum testosterone and AGD of male pubs from the middle and high dose groups were declined significantly (P < 0.01), the testis weight and body weight from high dose group were decreased significantly (P < 0.01), while the testis weight increased in the low dose group (P < 0.05). Under light microscope, PLC showed hyperplasia and cluster aggregation in the low dose group and focal hyperplasia in the middle and high dose group. The spermatogenic cells in seminiferous tubules showed decrease, apoptosis and unfix in the high dose group. Under transmission electron microscope, the PLC showed decreased lipid droplets, smooth endoplasmic reticulum and mitochondriae in the treated group. The mRNA expression of IGF-I increased in the low dose group, and the protein expression of StAR decreased in the middle and high dose group.
CONCLUSIONLactating exposure to DEHP may interfere with the synthesis of testosterone of PLC in male pubs, the decrease of StAR and the damage of PLC may be involved in it.
