at a gentleman’s club.
在一个绅士俱乐部
We know that lap dancers’ earnings fluctuate a lot, so it seemed like
我们知道脱衣舞娘的工资波动很大，所以这似乎
an ideal set-up for being able to ask them,
可以问它她们收入情况
“How much have you earned night by night, shift by shift?”,
你不停的跳舞，一晚上接一晚上，能赚多少钱呢
and to be able to track that in relation to where they are in the menstrual cycle.
可以追踪她们月经期与收入的关系
And we thought that was a pretty cool way of quantifying
female attractiveness to males.
我们认为这是一个很好的方法来量化女性对男性的吸引力
The dancers provided Miller’s team with information about their
earnings and menstrual cycles
舞娘提供给Miller的团队关于她们收入和月经期的信息
over a period of 300 work shifts –
超过300个轮班工作
the equivalent of about 5,000 lap dances for their male customers.

The results were surprisingly strong.

you’re earning higher tips,you’re getting called over
for more lap dances.

Miller’s research suggests a link between female ovulation
Miller的研究表明了女性的排卵期
and attractiveness to men.

But if women are unconsciously controlling men’s actions once
a month, what actually happens?

more attractive to men during oestrus.

Once again,it’s ovulation to the rescue.

Ovulation occurs on one side one month, the other side another month.
这个月排卵发生在一侧，下个月就是另一侧
So, on the times that the egg is going to be ovulated

from the ovary on the left,

so only sperm that are expressing the right molecules
actually are allowed through.

the leukocytes have been trying to kill them along the way,

the fallopian tubes are very difficult to study,

so difficult, in fact, some scientists are willing
to go to extraordinary lengths.
