Gonadotropin therapy is commonly used to induce virilization and spermatogenesis in male isolated hypogonadotropic hypogonadism (IHH) patients. In clinical practice, 5.6%-15.0% of male IHH patients show poor responses to gonadotropin treatment; therefore, testosterone (T) supplementation can serve as an alternative therapy to normalize serum T levels and promote virilization. However, treatment with exogenous T impairs spermatogenesis and suppresses intratesticular T levels. This retrospective study aimed to determine whether oral testosterone undecanoate (TU) supplementation together with human chorionic gonadotropin (hCG) would negatively affect spermatogenesis in IHH patients compared with hCG alone. One hundred and seven IHH patients were included in our study. Fifty-four patients received intramuscular hCG and oral TU, and 53 patients received intramuscular hCG alone. The median follow-up time was 29 (range: 12-72) months in both groups. Compared with the hCG group, the hCG/TU group required a shorter median time to normalize serum T levels (P < 0.001) and achieve Tanner stage (III and V) of pubic hair and genital development (P < 0.05). However, there were no significant differences in the rate of seminal spermatozoa appearance, sperm concentration, or median time to achieve different sperm concentration thresholds between the groups. In addition, there were no significant differences in side effects, such as acne and gynecomastia, observed in both groups. This study indicates that oral TU supplementation together with hCG does not impair spermatogenesis in treated IHH patients compared with hCG alone, and it shortens the time to normalize serum T levels and promote virilization.

In this study, we investigated the genetics, clinical features, and therapeutic approach of 14 patients with 5α-reductase deficiency in China. Genotyping analysis was performed by direct sequencing of PCR products of the steroid 5α-reductase type 2 gene (SRD5A2). The 5α-reductase activities of three novel mutations were investigated by mutagenesis and an in vitro transfection assay. Most patients presented with a microphallus, variable degrees of hypospadias, and cryptorchidism. Eight of 14 patients (57.1%) were initially reared as females and changed their social gender from female to male after puberty. Nine mutations were identified in the 14 patients. p.G203S, p.Q6X, and p.R227Q were the most prevalent mutations. Three mutations (p.K35N, p.H162P, and p.Y136X) have not been reported previously. The nonsense mutation p.Y136X abolished enzymatic activity, whereas p.K35N and p.H162P retained partial enzymatic activity. Topical administration of dihydrotestosterone during infancy or early childhood combined with hypospadia repair surgery had good therapeutic results. In conclusion, we expand the mutation profile of SRD5A2 in the Chinese population. A rational clinical approach to this disorder requires early and accurate diagnosis, especially genetic diagnosis.

ObjectiveTo investigate the correlation of the levels of reproductive hormones and oxidative stress in the seminal plasma with semen parameters in obese males.

METHODSBased on the body mass index (BMI), we divided 138 infertile men into three groups: normal (BMI <24 kg/m2, n = 48), overweight (24 kg/m2≤BMI<28 kg/m2, n = 47), and obesity (BMI ≥28 kg/m2, n = 43). We determined the concentrations of follicle-stimulating hormone (FSH), luteotropic hormone (LH), prolactin (PRL), testosterone (T) and estradiol (E2) in the serum by electrochemiluminescence and measured the levels of superoxide dismutase (SOD), glutathione-S-transferases (GSTs), reactive oxygen species (ROS) and malondialdehyde (MDA) in the seminal plasma by ELISA, compared the above indexes among the three groups, and analyzed their correlation with the semen volume, sperm concentration, total sperm count, and percentage of progressively motile sperm (PMS).

RESULTSThe semen volume was significantly lower in the obesity than in the normal group (［2.63 ± 0.74］ vs ［3.37 ± 1.00］ ml, P < 0.05), and so was the percentage of PMS in the overweight and even lower in the obesity than in the normal group (［47.91 ± 12.89］ and ［41.27 ± 15.77］ vs ［54.04 ± 13.29］%, P < 0.05). Compared with the normal group, both the overweight and obesity groups showed markedly decreased levels of serum T (［4.83 ± 1.42］ vs ［3.71 ± 1.22］ and ［3.49 ± 1.12］ ng/ml, P<0.05), T/LH ratio (1.53 ± 0.57 vs 1.19 ± 0.54 and 0.97 ± 0.51, P<0.05), SOD (［112.05 ± 10.54］ vs ［105.85 ± 6.93］ and ［99.33 ± 8.39］ U/ml, P<0.05), and GSTs (［31.75±6.03］ vs ［29.54±5.78］ and ［29.02±4.52］ U/L, P<0.05), but remarkably increased seminal plasma ROS (［549.93±82.41］ vs ［620.61±96.13］ and ［701.47±110.60］ IU/ml, P<0.05) and MDA (［7.46 ± 2.13］ vs ［8.72 ± 1.89］ and ［10.47 ± 2.10］ nmol/L, P<0.05). BMI was correlated positively with ROS and MDA, but negatively with the semen volume, PMS, T, T/LH, SOD and GSTs (P<0.05); LH negatively with sperm concentration, total sperm count and GSTs (P<0.05); PRL negatively GSTs (P<0.05); E2 positively with SOD (P<0.05); T positively with SOD (P<0.05) but negatively with MDA (P<0.05); T/LH positively with PMS and SOD (P<0.05) but negatively with ROS and MDA (P<0.05); SOD positively with semen volume, PMS and GSTs (P<0.05) but negatively with ROS and MDA (P<0.05); GSTs negatively with sperm concentration; total sperm count and MDA (P<0.05); ROS positively with MDA (P<0.01) but negatively with PMS (P<0.05); and MDA negatively with semen volume (P<0.05). Multivariate logistic regression analysis showed that the independent factors influencing the semen volume were BMI and GSTs, those influencing the total sperm count were BMI and T, and those influencing PMS were BMI and MDA.

CONCLUSIONSIncreased BMI induces changes in the levels of male reproductive hormones and seminal plasma oxidative stress and affects semen quality, which may be associated with male infertility.

ObjectiveTo investigate the relationship of the levels of serum androgens with lipid metabolism in middle-aged and elderly men in Zunyi, Guizhou.

METHODSUsing the stratified cluster sampling method, we conducted a questionnaire investigation and physical examinations among 437 men in Zunyi City. We divided the subjects into a middle-aged (40－64 ［53.20 ± 7.41］ years, n = 269) and an elderly group (=≥65 ［70.63 ± 4.66］ years, n = 168) and collected fasting elbow venous blood samples from them for measuring the levels of total testosterone (TT), sex hormone-binding globulin (SHBG), luteinizing hormone (LH), total cholesterol (TCH), triglyceride (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), calculated free testosterone (cFT), free testosterone index (FTI), and testosterone secretion index (TSI).

RESULTSCompared with the elderly group, the middle-aged males showed significantly lower SHBG, LH, HDL and LDL, and higher cFT, FTI, TSI, TG and TCH (all P < 0.05). TT and SHBG were negatively correlated with TG, TCH, HDL and LDL, while cFT was positively correlated with TCH, and so was FTI with TG, TCH with LDL, and TSI with TCH, HDL and LDL (all P < 0.05), but LH was negatively correlated with TG, TCH and LDL (all P < 0.05). Multivariate linear regression analysis showed that TT and SHBG were negatively correlated with TG, TCH, HDL and LDL, and so was LH with TCH, HDL and LDL (all P < 0.05).

CONCLUSIONSIn the middle-aged and elderly men in Zunyi, low concentrations of TT, SHBG and LH were associated with the increased risk of high-TCH and -LDL dyslipidemia, low concentrations of TT and SHBG with that of high-TG dyslipidemia, while high concentrations of TT, SHBG and LH with that of low-HDL dyslipidemia.

ObjectiveTo screen out an effective substitute in the prescription of Shengjing Capsules (SJC), observe the effects of the redeveloped New SJC (NSJC) with cordyceps cephalosporium mycelia (CCM) substituted for the ingredient cordyceps sinensis in the treatment of spermatogenesis impairment (SI), and provide some experimental evidence for its application in the treatment of male infertility and sexual dysfunction.

METHODSWe equally randomized 192 male mice into 16 groups: normal saline control, SI model, high-, medium- and low-dose fermented cordycepin powder (FCP, 1.60, 0.80 and 0.40 g/kg), high-, medium- and low-dose CCM (1.60, 0.80 and 0.40 g/kg), high-, medium- and low-dose cordyceps mortierella mycelia (CMM, 1.60, 0.80 and 0.40 g/kg), high-, medium- and low-dose fermented cordyceps sinensis (FCS, 1.60, 0.80 and 0.40 g/kg), SJC (0.80 g/kg), and vitamin E (VE, 0.25 g/kg), with the SI model established in all the mice and the normal controls injected intraperitoneally with cyclophosphamide at 60 mg/kg qd for 5 consecutive days. After intragastrical medication with respective drugs, we obtained the body mass index (BMI), sexual organ coefficient, sperm count, sperm motility, and percentage of morphologically abnormal sperm (MAS) of the mice. We also randomly divided 70 male rats into 7 groups of equal number: normal control, SI model, high-, medium- and low-dose NSJC (1.12, 0.56 and 0.28 g/kg), SJC (0.56 g/kg), and VE (0.18 g/kg), the SI model constructed in the latter 6 groups of rats by gavage of adenine at 200 mg/kg qd for 5 consecutive days. After intragastrical medication with respective drugs, we examined the BMI, coefficients of sexual and renal organs, levels of reproductive hormones, testicular morphology, and fertility of the animals.

RESULTSAfter medication, the mice in different groups showed different degrees of improvement in the cyclophosphamide-induced slow growth, significant increases in the testicular and epididymal coefficients, sperm count, motility and viability (P < 0.05 or P < 0.01), and a remarkable reduction in the percentage of MAS (P < 0.05 or P < 0.01). The effect was particularly significant in the CCM group and therefore CCM was chosen as the best substitute ingredient in the redeveloped NSJC. Compared with the rats in other groups, those treated with NSJC exhibited significant increases in the BMI, coefficients of sexual and renal organs and levels of serum follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone (T) and estradiol (E2) (P < 0.05 or P < 0.01), improvement of the pathologically damaged testicular morphology, elevation of the pregnancy rate and litter size, and recovery from adenine-induced SI.

CONCLUSIONSThe redeveloped New Shengjing Capsules with cordyceps cephalosporium mycelia substituted for the ingredient cordyceps sinensis can improve fertility and reverse spermatogenesis impairment in male rats. The new prescription may also be applied to the clinical treatment of male infertility and sexual dysfunction.

ObjectiveTo investigate the role of the serum inhibin B (INHB) level in evaluating the testicular function of the prepubertal patient with varicocele (VC) after high ligation of the spermatic vein (HLSV).

METHODSThis study included 31 prepubertal male patients with left VC, averaging 12.55 years of age and 9 complicated by right VC. We collected peripheral blood samples before and at 4, 12 and 26 weeks after HLSV as well as spermatic venous blood samples intraoperatively for determination of the levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone (T), anti-sperm antibody (AsAb) and serum INHB by ELISA.

RESULTSCompared with the baseline, statistically significant differences were observed in the INHB level in the peripheral blood at 12 and 26 weeks after operation (［255.18 ± 69.97］ vs ［141.78 ± 59.82］ pg/ml, P < 0.05) and that in the spermatic venous blood intraoperatively (［255.18 ± 69.97］ vs ［412.44 ± 259.42］ pg/ml, P < 0.01). Spearman's analysis showed a negative correlation between the level of INHB and that of FSH (r = －0.224, P < 0.01).

CONCLUSIONSThe level of serum INHB in the peripheral blood of the prepubertal VC patient is decreased within 6 months after HLSV and negatively correlated with that of FSH. The levels of INHB and FSH may well reflect the testicular function of the prepubertal VC patient.

ObjectiveTo explore the antagonistic effect of vitamin E (VE) on male reproductive toxicity induced by di-2-ethylhexyl phthalate (DEHP) in pubertal SD rats and its underlying mechanisms.

METHODSThirty 5-week-old male SD rats were randomly divided into five groups of equal number, corn oil control, low-dose (10 mg/kg/d), medium-dose (100 mg/kg/d) and high-dose DEHP exposure (500 mg/kg/d), and VE intervention (high-dose DEHP + VE ［100 mg/kg/d］), and treated respectively for 30 successive days. At 3 days after treatment, the testes of the animals were harvested for determination of the oxidative stress index, serum reproductive hormone levels, cauda epididymal sperm parameters, and expressions of cell apoptosis-related genes and proteins.

RESULTSCompared with the control group, the rats of the medium- and high-dose DEHP groups showed significant decreases in the levels of such serum reproductive hormones as follicle-stimulating hormone (FSH), luteinizing hormone (LH) and testosterone (T), sperm parameters as average path velocity (VAP), straight line velocity (VSL), curvilinear velocity (VCL), straightness (STR), linearity (LIN) and wobble (WOB), and the activities of superoxide dismutase (SOD) and glutathione peroxide (GSH-Px), but significant increases were observed in the latter two groups in the content of malondialdehyde (MDA)(［3.32±0.87］ nmol/mg pro vs ［2.13±0.49］ nmol/ mg pro), mRNA expressions of Bad, Bax, Cytochrome C, Caspase-3 and the Bax/Bcl-2 ratio, and protein expressions of Cytochrome C and Caspase-3. In comparison with the high-dose DEHP group, the VE intervention group exhibited remarkably increased serum LH and T levels, sperm VAP, VSL, VCL, STR and WOB, and activities of SOD and GSH-Px, but markedly decreased mRNA expressions of Bad, Bax, Cytochrome C, Caspase-3 and the Bax/Bcl-2 ratio as well as the protein expressions of Cytochrome C and Caspase-3 in the testis tissue (P<0.05).

CONCLUSIONSExposure to DEHP induces androgen secretion disorders, causes oxidative damage to the testicular tissue, activates the mitochondrial apoptosis pathway in the testis, and ultimately reduces the quality of epididymal sperm, while VE can protect the rat testis from DEHP-induced reproductive toxicity.

OBJECTIVETo observe the efficacy differences between acupuncture combined with medication and medication alone for infertility patients with polycystic ovary syndrome (PCOS).

METHODSAccording to random number table, a total of 60 infertility patients with PCOS were randomly assigned into an observation group and a control group, 30 cases in each one. The patients in the control group were treated with diane-35 from the 3rd day into menstruation, and one menstrual cycle was taken as a session of treatment. At the same time of using diane-35, the patients in the observation group were treated with acupuncture at Guanyuan (CV 4), Qihai (CV 6), Sanyinjiao (SP 6), Zusanli (ST 36), Zigong (EX-CA 1), Shenshu (BL 23), Pishu (BL 20), Weishu (BL 21) and Ganshu (BL 18) during non-menstruation period; the acupuncture was given once every two days, three treatments per week. The patients in both groups were treated for two sessions. The basic sex hormone and body mass index (BMI) were compared between the two groups before and after treatment. After ovulation induction treatment, the endometrial thickness, amount of mature follicle, ovulation rate, clinical pregnancy rate, occurrence rate of ovarian hyperstimulation syndrome (OHSS) and the number of early spontaneous abortion were compared between the two groups during ovulation.

RESULTSAfter treatment, the luteinizing hormone (LH), testosterone (T) and BMI reduced in the observation group (all <0.05), while only LH reduced in the control group (<0.05). The reducing of estradiol (E), T and BMI in the observation group was more significant than that in the control group (all <0.05). The ovulation rate was 93.3% (28/30) in the observation group, which was higher than 80.0% (24/30) in the control group (<0.05). The rate of clinical pregnancy was 43.3% (13/30) in the observation group, which was higher than 33.3% (10/30) in the control group (<0.05). The differences of endometrial thickness, amount of mature follicle, occurrence rate of OHSS and number of early spontaneous abortion were not significant between the two groups (all >0.05).

CONCLUSIONAcupuncture as adjunctive treatment could improve BMI, reduce the levels of LH, E and T, increase ovulation reaction and effectively shorten reproduction cycles in infertility patients with PCOS.

OBJECTIVETo compare the clinical efficacy differences between acupuncture at back- points of five , Geshu (BL 17), Shenmen (HT 7) and regular medication for the treatment of menopausal insomnia.

METHODSA total of 128 female patients of menopausal insomnia were randomly divided into an observation group and a control group, 64 cases in each one. Four patients in the observation group and 2 patients in the control group dropped out during the treatment. The patients in the observation group were treated with acupuncture at Feishu (BL 13), Xinshu (BL 15), Pishu (BL 20), Ganshu (BL 18), Shenshu (BL 23), Geshu (BL 17) and Shenmen (HT 7), once a day, and there was an interval of 2 days between every 5 days of treatment. The patients in the control group were treated with oral administration of alprazolam (0.4 mg or 0.8 mg) before sleep. Three-week treatment was taken as one course, and totally three courses were given in the two groups. Pittsburgh sleep quality index (PSQI), levels of estradiol (E), follicle-stimulating hormone (FSH) and luteinizing hormone (LH) were observed before treatment and 30 days after treatment; the efficacy was evaluated 30 days after treatment.

RESULTSEach item score and total score of PSQI 30 days after treatment were lower than those before treatment in the two groups (all <0.05), the scores in the observation group were lower than those in the control group (all <0.05). The levels of E 30 days after treatment were higher than those before treatment in the two groups (both <0.05), but the level of FSH and LH 30 days after treatment were lower than those before treatment in the two groups; the level in the observation group was superior to that in the control group (all <0.05). The total effective rate was 98.3% (59/60) in the observation group, which was better than 95.2% (59/62) in the control group (<0.05).

CONCLUSIONAcupuncture at Feishu (BL 13), Xinshu (BL 15), Ganshu (BL 18), Pishu (BL 20), Shenshu (BL 23), Geshu (BL 17), and Shenmen (HT 7) has better efficacy for menopausal insomnia than alprazolam.
