For years, scientists have been trying to develop a safe and effective version of the pill for men, and a new drug candidate could be the contraceptive we've been looking for. 多年来，科学家们一直在努力开发出一种安全有效的男性避孕药，一种新的候选药物可能就是我们一直在寻找的避孕药。 Now, scientists in the US announced that an experimental oral drug called 11-beta-MNTDC looks to be safe and tolerable, based on results from a phase 1 clinical trial involving 40 men. 现在，美国科学家宣布，一种名为11-β- mntdc的实验性口服药物看起来是安全且可耐受的，这是基于40名男性参与的一期临床试验的结果。 "Our results suggest that this pill, which combines two hormonal activities in one, will decrease sperm production while preserving libido," says male reproduction biologist Christina Wang from the Los Angeles Biomedical Research Institute (LA BioMed). 洛杉矶生物医学研究所(LA BioMed)的男性生殖生物学家Christina Wang说:“我们的研究结果表明，这种将两种激素活动结合在一起的药物，将在保持性欲的同时降低精子产量。” In the clinical trial, Wang and her team recruited 40 healthy men. 在临床试验中，王和她的团队招募了40名健康男性。 For 28 days, 30 of these participants took a low or higher daily dose of the 11-beta-MNTDC, while the remaining 10 men took a placebo. |
