An interesting article on PMS (yes click me i am a link)
"During the fertile (follicular) phase of the menstrual cycle,
women ornament more (Haselton, Mortezaie, Pillsworth, Blecke-Rechek, & Frederick,
2007) and wear sexier/bolder clothing (Grammer, Renninger, & Fischer, 2004), go to
clubs more (Haselton & Gangestad, 2006), are more attentive to “maleness” (Macrae,
Alnwick, Milne, & Schloerscheidt, 2002), increase ranging activities including
locomotion and volunteering for more social activities (Fessler, 2003), and flirt more
with men not their mates (Haselton & Gangestad, 2006; Gangestad, Thornhill, & Garver,
2002). Women’s facial appearance (Roberts, Havlicek, Flegr, Hruskova, Little, Jones,
Perrett, & Petrie, 2004) and body odors (Doty, Ford, Preti, & Huggins, 1975; Singh &
Bronstad, 2001; Thornhill, Gangestad, Miller, Scheyd, McCullough, & Franklin, 2003)
are also more attractive to men, and their sexual desire is higher (Haselton & Gangestad,
2006; Gangestad, Thornhill, & Garver, 2002; Bullivant, Sellergren, Stern, Spencer,
Jacob, Mennella, & McClintock, 2004) during the fertile phase of the menstrual cycle."
