相比之下,如果女性想恢复生育能力,就必须要在数星期甚至数月前停止服用药物.
Last night, family planning experts said a reversible male contraceptive could benefit millions of couples where the woman cannot take the Pill for medical reasons.
昨晚,计划生育专家们称,可逆的男性避孕药将造福数百万由于医疗原因妻子无法服用避孕药的夫妇.
And it would save men from being trapped into having children they did not want, they added.
此外,这还能够解救那些不想要孩子却受到诱骗的男性.
With global sales of contraceptives topping 13 billion a year, the market for a reversible male contraceptive could be huge, but some cast doubt on the idea of a male pill, doubting women will trust men to take it.
鉴于每年避孕药的全球销售额高达130亿英镑,可逆的男性避孕药的市场前景也将相当可观,但也有些人对男性避孕药提出质疑,怀疑女性是否会信任由男性服用避孕药.
Lead researcher Professor John Howl, of Wolverhampton University, last night described how effective their sperm-stopping agent had been in lab tests.
昨晚,伍尔弗汉普顿大学首席研究员约翰•豪尔教授描述了阻碍精子游动的药剂在实验室试验的效果.
He said: "The results are startling and almost instant."
他说："结果令人相当震惊——药剂几乎是即时生效.
When you take healthy sperm and add our compound, within a few minutes the sperm basically cannot move. Male infertility is often the result of poorly moving sperm, called low motility.
将合成物放入健康的精子后,仅不到几分钟时间,精子基本就无法动弹.男性不育常常是因为精子活力低,即"弱精".
Using this, the Wolverhampton team, together with Portuguese researchers, made a compound called a cell-penetrating peptide, which gets inside sperm and brings them to a standstill.
利用这一点,伍尔弗汉普顿研究团队与葡萄牙研究人员共同研制出了一种名为细胞穿透肽的合成物,此合成物能够进入精子体内,阻止精子游动.
Prof Howl said: "This is a totally unique approach nobody else has ever done this before. Peptides are short chains of amino acids that can influence how human cells work."
