目的 比较来曲唑和氯米芬治疗极严重少精子症的治疗效果。方法 选取2020—2021年在本生殖中心门诊50例极严重少精子症病例,分为2组,A组(来曲唑,研究组n=26)、B组(氯米芬,对照组n=24)。结果 来曲唑和氯米芬治疗后1月、3月,A组精子浓度明显提高,优于B组[(4.5±3.1) vs (2.0±1.3);(8.3±3.5) vs (2.0±1.8),P<0.05]。通过卵胞浆内单精子注射/体外受精胚胎移植治疗,A组妊娠16例(61.5%),B组妊娠11例(45%)。2组治疗后的血清卵泡刺激素、黄体生成素、睾酮升高[(5.9±3.8) vs (20.3±2.6);(3.6±2.8) vs (9.5±5.7);(13.6±10.5) vs (25.3±10.8),P<0.05],A组雌二醇水平降低[(36.8±20.6) vs (7.6±2.5),P<0.05]。结论 来曲唑治疗极严重少精子症有较理想的临床治疗效果,明显优于氯米芬。

Objective To explore and compare the therapeutic effects of letrozole and clomiphene in the treatment of extremely severe oligospermia. Methods A tatal of 50 cases of extremely severe oligosperospermia in the reproductive center from 2020 to 2021 were selected and divided into two groups, group A (letrozole, study group n=26) and B (clomiphene, control group n=24). Results After letrizole and clomiphene treated for 1 and 3 months, sperm concentration in group A was significantly better than group B[(4.5±3.1) vs (2.0±1.3);(8.3±3.5) vs (2.0±1.8),P<0.05]. With ICSI/IVF, 16 cases (61.5%) succeed in encyesis in group A, 11 cases (45%) in group B. Serum follicle stimulating hormone, luteinizing hormone and testosterone levels were significantly increased after treatment [(5.9±3.8) vs (20.3±2.6), (3.6±2.8) vs (9.5±5.7), (13.6±10.5) vs (25.3±10.8), P<0.05]. The level of estradiol in group A decreased [(36.8±20.6) vs (7.6±2.5), P<0.05]. Conclusions Letrozole has ideal clinical treatment effect, which is obviously superior to clommiphene.

目的 探讨彩色多普勒超声在无精子症患者睾丸穿刺活检中的应用价值。方法 回顾性分析2012年11月—2015年2月在我科诊断为无精子症的53例患者的病例资料。所有患者进行常规阴囊超声检查,采用频谱多普勒检测睾丸动脉(TA)、睾丸内动脉(ITA)的收缩期最大速度(PSV)、舒张末期速度(EDV)和阻力指数(RI)。采用彩色多普勒超声观察睾丸内的血管分布及其数目,并进行半定量评分。所有患者进行睾丸穿刺活检并进行Johnsen评分。结果 47例患者诊断为梗阻性无精子症(OA),6例患者诊断为非梗阻性无精子症(NOA)。0A组睾丸的平均体积(15.3±3.6) mL,NOA组睾丸的平均体积(7.1±2.8) mL,差异有统计学意义(P＜0.01);OA组与NOA组患者睾丸的血流参数(PSV、EDV、RI) 结果有统计学意义(P＜0.05);OA组与NOA组睾丸内血管半定量分级有的差异,其差异有统计学意义(P＜0.01)。结论 彩色多普勒超声检查对睾丸生精功能有很好的预测作用,可作为鉴别OA患者和NOA患者的指标。

Objective To explore the application value of color Doppler ultrasound in patients with azoospermia who underwent testicular needle biopsy. Methods Retrospective analysed the clinical data of 53 cases patients with azoospermia from 2012 November to 2015 February in our department.All patients underwent routine scrotal ultrasonography, to detecte the peak systolic velocity (PSV), end diastolic velocity (EDV) and resistance index (RI) of testicular artery (TA)and intratesticular artery (ITA)with spectral Doppler ultrasound. Color Doppler ultrasound was used to observe the distribution and the number of blood vessels in the testicle, and semi quantitative score. All patients underwent testicular biopsy and Johnsen score. Results 47 patients were diagnosed as obstructive azoospermia(OA), 6 patients were diagnosed as non obstructive azoospermia(NOA). The average volume of testis was (15.3±3.6)mL in 0A group. The average volume of testis was (7.1±2.8) mL in N0A group.There was significant difference (P<0.01). The blood flow parameters(PSV, EDV, RI) results between OA group and NOA group have obvious difference,the difference was statistically significant (P<0.05). The semi quantitative classification of testicular vessels between OA group and NOA group have obvious difference,the difference was statistically significant (P< 0.01). Conclusion Color Doppler ultrasound is a good predictor of testicular spermatogenic function, can be used as the identification index of patients with OA and patients with NOA.

目的 观察十一酸睾酮联合左卡尼汀治疗特发性弱精症的疗效。方法 回顾性分析2012年11月—2014年6月在我科诊断为弱精子症的386例患者的临床资料,按标准分成轻(A组)、中(B组)、重(C组)3组。分别给予左卡尼汀、十一酸睾酮联合左卡尼汀治疗,观察两种治疗方法对特发性弱精子症的疗效。结果 A组、B组患者两种治疗方法治疗后精子PR均有升高,差异有统计学意义(P＜0.05),C组患者给予左卡尼汀治疗患者治疗后PR无改善,差异无统计学意义(P＞0.05);十一酸睾酮联合左卡尼汀治疗患者治疗后PR升高,差异有统计学意义(P＜0.05)。A、B、C组患者给予左卡尼汀治疗的有效率分别是47.6%,41.7%,18.9%,总有效率为37.9%;A、B、C组患者给予十一酸睾酮联合左卡尼汀治疗的有效率分别是52.6%,45.5%,34.7%,总有效率为45.5%。A组、B组患者两种治疗方法疗效无差异(P＞0.05);C组患者给予十一酸睾酮联合左卡尼汀组有效率高于给予左卡尼汀组,差异有统计学意义(P＜0.05)。结论 十一酸睾酮联合左卡尼汀治疗特发性弱精子症的疗效优于左卡尼汀单一用药。

Objective To observe the effects of eleven acid testosterone combined with L-carnitine on curing idiopathic asthenospermia. Methods Retrospective analysed the clinical data of 386 patients with asthenospermia patients from November 2012 to June 2014 in our department.According to the standard,the patients were divided into mild A,moderate B,severe C in 3 groups,given L-carnitine treatment and given eleven acid testosterone combined with L-carnitine treatment.We observed effect of the two therapeutic methods for the treatment of idiopathic asthenospermia. Results The sperm PR were increased,In group A and group B patients after treated.The difference was statistically significant(P<0.05).In group C,the patients received the treatment of L-carnitine,the sperm PR has no obvious improvement,There was no significant difference(P>0.05).The patients received the treatment of eleven acid testosterone combined with L-carnitine the sperm PR significantly increased,the difference was statistically significant(P<0.05).The treatment efficiency of A,B,C group received L-carnitine were 47.6%,41.7%,18.9%,the total effective rate was 37.9%.The treatment efficiency of A,B,C group received eleven acid testosterone combined with L-carnitine were 52.6%,45.5%,34.7%,the total effective rate was 45.5%;There was no significant difference in group A and group B(P>0.05).The treatment efficiency in group C received eleven acid testosterone combined with L-carnitine group is obviously higher than that given L-carnitine group,the difference was statistically significant(P<0.05). Conclusion The curative effect of eleven acid testosterone combined with L-carnitine in the treatment of idiopathic asthenospermia is better than that of L-carnitine single drug treatment.
