  I mean,

  I was reading in your book about how mating and attraction preferences change for a woman throughout her cycle.

• 00:07

  Yeah.

• 00:07

  So throughout a woman's 28-day cycle, does she always want a nice guy?

• 00:13

  No. So women's...

• 00:15

  partner preferences and the types of qualities that women tend to prioritize in their choice of partners do change across the menstrual cycle.

• 00:22

  And this changes with our sex hormones.

• 00:25

  So during the early part of the menstrual cycle, both sets of sex hormones,

• 00:30

  so our estrogen and progesterone, which is our second primary sex hormone, they are low.

• 00:36

  And then as estrogen begins to increase,

• 00:39

  which is something that happens as eggs start to mature in the ovary.

• 00:44

  And as the eggs are maturing, they release estrogen.

• 00:47

  And as a dominant egg is chosen and begins to fully mature,

• 00:53

  so that way it will be released at ovulation.

• 00:56

  Which is how many days into the cycle?

• 00:57

  Usually estrogen really starts to surge right around day nine of the cycle.

• 01:03

  But it really hits its high point usually right around day 14,

• 01:08

  which is when ovulation occurs.

• 01:09

  So estrogen begins rising sharply around day nine of the cycle.

• 01:13

  And again, the first day of the menstrual cycle is the day that your period arrives.
