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.
