This small-scale randomized controlled study aimed to examine the effect of l-arginine supplementation on the human chorionic gonadotropin (hCG)-positive rate and clinical pregnancy rate (CPR) in women undergoing assisted reproductive technology (ART) treatment for 3 months. From November 2017 to March 2018, 120 patients aged less than 40 years and planning for egg retrieval for embryo transfer were enrolled. The patients were divided into the AS2000 group (n = 36; l-arginine, 2 g; folate, 400 μg; and vitamin E, 10 mg), AS1000 group (n = 37; l-arginine, 1 g; and folate, 200 μg), and control group (n = 36). The main outcome was the hCG-positive rate or CPR in 3 months. The cumulative hCG-positive rates during the administration period were 44.2%, 54.2%, and 52.1%, and the CPRs were 39.5%, 41.7%, and 47.9% in the control, AS1000, and AS2000 groups, respectively. Odds ratios of the hCG-positive rate and CPR in the global l-arginine group (AS1000 and AS2000) versus those in the control group were 1.33 (95% confidence interval [CI], 0.62-2.90) and 1.11 (95% CI, 0.51-2.46), respectively. In the subgroup of women receiving ART because of male infertility, the hCG-positive rate and CPR were significantly increased in the l-arginine groups compared to those in the control group (13.42 [95% CI, 1.42-366.9] and 13.62 (95% CI, 1.42-367.6), respectively). Thus, arginine supplementation may be an option for women who desire pregnancy, especially those undergoing an ART program because of male infertility.

L-精氨酸对使用辅助生殖技术的女性的有益作用:一项小规模随机对照试验

这项小规模随机对照研究旨在检查补充 l-精氨酸对接受辅助生殖技术 (ART) 治疗 3 个月的妇女的人绒毛膜促性腺激素 (hCG) 阳性率和临床妊娠率 (CPR) 的影响。2017年11月至2018年3月,120名40岁以下计划取卵进行胚胎移植的患者入组。患者分为 AS2000 组(n = 36;l-精氨酸,2 g;叶酸,400 μg;和维生素 E,10 mg)、AS1000 组(n = 37;l-精氨酸,1 g;和叶酸, 200 μg)和对照组(n = 36)。主要结果是 3 个月内 hCG 阳性率或 CPR。给药期间累积hCG阳性率分别为44.2%、54.2%和52.1%,对照组、AS1000和AS2000组的CPR分别为39.5%、41.7%和47.9%,分别。全球 L-精氨酸组(AS1000 和 AS2000)与对照组的 hCG 阳性率和 CPR 的比值比为 1.33(95% 置信区间 [CI],0.62-2.90)和 1.11(95% CI, 0.51-2.46),分别。在因男性不育而接受 ART 的女性亚组中,与对照组相比,L-精氨酸组的 hCG 阳性率和 CPR 显着增加(13.42 [95% CI,1.42-366.9] 和 13.62(95 % CI,分别为 1.42-367.6))。因此,对于希望怀孕的女性,尤其是那些因男性不育而接受 ART 计划的女性,补充精氨酸可能是一种选择。分别为 11(95% CI,0.51-2.46)。在因男性不育而接受 ART 的女性亚组中,与对照组相比,L-精氨酸组的 hCG 阳性率和 CPR 显着增加(13.42 [95% CI,1.42-366.9] 和 13.62(95 % CI,分别为 1.42-367.6))。因此,对于想要怀孕的女性,尤其是那些因男性不育而接受 ART 计划的女性,补充精氨酸可能是一种选择。分别为 11(95% CI,0.51-2.46)。在因男性不育而接受 ART 的女性亚组中,与对照组相比,L-精氨酸组的 hCG 阳性率和 CPR 显着增加(13.42 [95% CI,1.42-366.9] 和 13.62(95 % CI,分别为 1.42-367.6))。因此,对于希望怀孕的女性,尤其是那些因男性不育而接受 ART 计划的女性,补充精氨酸可能是一种选择。
