    • 摘要: Objective To evaluate testosterone pretreatment on the pregnancy outcomes in poor ovarian response(POR) patients undergoing assisted reproductive therapy(ART). Methods Search the original research paper published on the PubMed, EMBASE, Cochrane library,CNKI,CBM and WanFang database and collect all the randomized controlled trials using testosterone pretreatment before or during ovarian stimulation. The literature was published from January 2006 to January 2018. Two assessors independently screened the studies according to the criteria for inclusion and exclusion and assessed methodological quality according to the Cochrane Handbook. Stata 12.0 was used to do the meta-analysis. Results A total of 505 patients from 6 studies were enrolled to Meta-analysis. The study population for testosterone treatment was the experimental group, and the study population without testosterone treatment was the control group. Compared to the control groups, experimental groups were associated with increased clinical pregnancy rates [odds ratio(OR) =2.50, 95 % confidence interval (CI) =1.47,4.23], live birth rates[ OR=2.35, 95 % CI=1.22,4.50] and more oocytes retrieved [standard mean difference( SMD) =0.76, 95 % CI =0.55,0.97]. The total FSH dose and the total duration of FSH stimulation were decreased, SMD calculated were -0.58(95 % CI= -0.77,-0.38) and -0. 46 (95 % Cl=-0.65,-0.26). Conclusion Current RCT evidence suggests that testosterone pretreatment in patients with POR increases clinical pregnancy rates, birth rates, number of oocytes obtained, reduces FSH dose and time course, and improves ovarian response and pregnancy outcomes. However, there are currently a small number of studies in this field. Among the above indicators, only the dose of total FSH is statistically significant, and other results are not statistically significant. Therefore, more high-quality RCT studies are needed to prove this.%目的 系统评价睾丸酮用于卵巢低反应(poor ovarian response,POR)患者辅助生殖( assisted reproductive therapy, ART)治疗后,对妊娠结局的影响.方法 计算机检索PubMed数据库、EMBASE数据库、Cochrane图书馆、中国知网(CNKI)数据库、中国生物医学文献数据库( CBM)和万方医学数据库中发表于2006年1月至2018年1月前的原创性研究论文;收集采取睾丸酮治疗措施的 POR 型患者,执行 ART 后的随机对照实验(randomized controlled trial,RCT)文献.由2 位评价员根据纳入及排除标准独立进行文献筛选,并对选取的文献进行质量评价.采用Stata 12.0软件对筛选到的RCT文献进行荟萃分析,分析睾丸酮用于POR患者ART后,对妊娠结局的影响.结果 共纳入6 项研究, 505 例患者.进行睾丸酮处理的研究人群为研究组,未进行睾丸酮处理的研究人群为对照组.研究组与对照组比较,临床妊娠率( OR =2.50,95 % CI 为1.47, 4.23)、出生率(OR =2.35,95 % CI为1.22,4.50)、获卵数(SMD=0.76,95 % CI 为0.55,0.97)均明显增加,卵泡刺激素(follicle stimulating hornone,FSH)的总剂量( SMD= -0.58,95 % CI为-0.77,-0.38),FSH 的使用时程(SMD= -0.46,95 % CI为-0.65,-0.26)均明显减少.结论 目前的RCT证据表明,对POR患者采用睾丸酮预处理会增加临床妊娠率、出生率、获卵数,减少 FSH 剂量和使用时程,改善卵巢反应和妊娠结局.但是目前该领域的研究样本量较少,上述指标中,只有FSH的总剂量具有统计学意义,其它结果尚无统计学意义,因此未来还需要更多的高质量RCT研究来进行佐证.

    • 摘要: The effects of testosterone, estradiol and the combination of the two hormones on the main development stages and population growth rate of Asplanchna brightwelli were studied with ecological experiment methods. The resu-lts showed that the 48h LC50 of testosterone (T) was 9.56 mg/L, Y=1.9793X+3.0591 (R2=0.9211); 48h LC50 of estradiol (E) was 8.18 mg/L, Y=3.5292X+1.7788 (R2=0.9195). Testosterone and estradiol significantly reduced the lifespan, the number of offspring, and population growth rate (r) except the condition under the concentration of 0.5 mg/L. Treat-ment with testosterone at the concentration of 8 mg/L significantly prolonged the pre-reproductive time by 11.71%, and decreased the lifespan and the number of offspring by 52.22% and 82.20%, respectively. Treatment with estradiol at the concentration of 8 mg/L significantly prolonged the pre-reproductive time by 7.10%, and decreased the lifespan and the number of offspring by 49.75% and 83.33%, respectively. When the two hormones were at a total concentration of 8 mg/L, compared with the control groups, the pre-reproductive period significantly prolonged by 34.17%—48.01%; the mean life significantly shortened by 31.56%—42.12%; the number of offspring reduced by 24.44%—80.33%. At the 5d, the population growth rate of rotifers significantly declined by 30.00%, 37.14%, 41.43%, 60.00% and 65.71% when they were exposed to T6E2, T4E4, T8E0, T0E8 and T2E6, respectively. Consequently, testosterone and estradiol showed significant effects on the durations of different development stages of Asplanchna brightwelli and the characteristics of its population growth. Simultaneously, the two hormones showed synergistic effects and the rotifers were more sensi-tive to estradiol.%采用生态学实验方法,研究睾丸酮(Testoterone)和雌二醇(Estradiol)单一及组合对卜氏晶囊轮虫生命周期中主要发育阶段历时和种群增长率的影响.结果显示:睾丸酮(T)的48h LC50为9.56 mg/L,直线回归方程为Y=1.98X+3.06(R2=0.92);雌二醇(E)48h LC50为8.18 mg/L,直线回归方程为Y=3.53X+1.78(R2=0.92).除0.5 mg/L浓度组外,睾丸酮和雌二醇均显著缩短轮虫平均寿命、减少后代幼体个数以及降低种群增长率(r).其中8 mg/L睾丸酮与对照组相比显著延长轮虫生殖前期11.71%、平均寿命缩短52.22%,后代个数减少82.20%;8 mg/L雌二醇与对照组相比,生殖前期显著延长7.10%,平均寿命缩短49.75%,后代个数减少83.33%.在2种激素定量组合(8 mg/L)实验中,与对照组相比,各实验组的生殖前期显著延长34.17%—48.01%,平均寿命显著缩短31.56%—42.12%,后代个数明显减少24.44%—80.33%;第5天,处理组T6E2、T4E4、T8E0、T0E8和T2E6的r值比对照组分别降低30.00%、37.14%、41.43%、60.00% 和65.71%.研究结果显示睾丸酮和雌二醇对卜氏晶囊轮虫生长发育及种群增长率有明显影响,并且卜氏晶囊轮虫对雌二醇表现更为敏感,2种激素呈现出协同作用.

    • 摘要: 最近,我遇见一位35岁的ED(勃起功能障碍,即“阳痿”)患者,询问中,患者说自己热衷于健身房锻炼,为了早日锻炼出好身材,在教练和健友的怂恿下服用雄性激素——十一酸睾丸酮(商品名:安特尔,以往叫安雄),结果似乎身体肌肉健硕了,但是出现性功能障碍现象,于是停用十一酸睾丸酮.半年后,感觉勃起功能障碍日趋严重,检测性激素发现睾酮低于正常值.
