We often believe that fertility starts and ends in the bedroom - that it can be boosted with just a little more cuddling, longer foreplay, and a return to hand-holding.

我们通常认为房事止于床笫之间--你可以用多一点儿的拥抱、更长的前戏和更多的温存来刺激对方的兴致。

But research has revealed that too much exercise could be affecting our baby-making abilities.

但是据一项研究显示，运动过度可能会影响我们的生育能力。

'Your body views exercise as a form of stress and this signals to the hypothalamus in the brain it might not be a safe time for reproduction,' Australian exercise physiologist¹ Sarah King wrote on News Corp.

澳大利亚运动生理学家萨拉·金在News Corp上写道：“人体会将运动视为一种压力，而下丘脑的这个信号对人类生殖活动来说可不是什么好事儿。”

'A cascade² of changes...can occur which leads to menstrual cycle changes, failure to ovulate or complete loss of periods in some women.'

“一连串的变化可能会出现，导致女性生理周期失调、无法排卵，甚至可能会导致某些女性完全绝经。”

A regular exercise regime has been proven to improve reproductivity as it helps lower stress levels, improves heart health and, of course, keeps weight in check.

定期运动已经被证明可以提高我们的生殖能力，因为那可以帮助我们降低压力水平、改善心脏健康，而且当然还能帮助我们保持体重。

A US study even found that women who exercised at least 30 minutes a day were less likely to suffer from ovulation disorders³ that reduced their fertility.

美国一项研究甚至发现，女性如果每天至少锻炼30分钟，换上排卵障碍从而降低生育能力的可能性就会降低。

But multiple studies have also shown that too much intense exercise can actually hurt fertility in the long run, irregulating both periods and hormone⁴ production.

但是许多研究也显示，如果激烈运动过度，长期来看实际上会损害生育能力，导致女性生理周期失调和激素分泌紊乱。

There's no one size fits all when it comes to the optimal⁵ weight or body type one needs to have a body.

对于生孩子最理想的体重和体型是什么样的这个问题，并没有适合所有人的标准。

King suggested women aim for a healthy BMI between 18.5 to 24.9 and consume a healthy diet that's heavy on whole foods.

萨拉建议女性朋友保持一个在18.5到24.9之间的健康体重指数，并保持一个侧重全食的饮食习惯。

'This weight range is associated with optimal reproductive function and reduces your chance of complications, such as gestational diabetes⁶, during pregnancy,' she wrote.

她写道：“这个体重范围的人有最佳的生殖功能，还能够减少诸如孕期糖尿病等怀孕期间的并发症。”
