Libido tends to increase in women prior to and during ovulation, coinciding with the optimal time for fertility.

“the four to five days prior to ovulation, there is a dramatic increase in libido. That dramatic increase in libido is triggered by a number of things, but some of those things include the spike in FSH that occurs, the spike in LH that occurs, and some associated increases in androgens, things like DHEA and testosterone, which, just as in males can be related to libido, in females trigger libido.”

“Well, those estrogen increases just prior to ovulation are in part responsible for the increases in libido. But it's also the presence of increased androgen just prior to ovulation.”

“Earlier, we talked about one thing, which is there's an increase in libido just prior to ovulation. This relates to, in part, an increase in some of the androgens, things like DHEA, but also testosterone and some related androgens that can increase libido both in males and females”

“But there is data to suggest that libido does increase prior to ovulation and during ovulation, I think it's like a couple of days prior, because that's the optimal time for fertility.”
