laikam pat domats ne auglība kā tāda bet "apstākļi reprodukcijai"

ideja tāda, ka
- apstakļos kas nav "favorable to successful immediate reproduction" - PMS nav,
- apstakļos, kas ir "favorable to successful immediate reproduction" - PMS ir (tikai hipotēze:))

Under conditions favorable to successful immediate reproduction, women are expected to experience the heightened positive states during the fertile phase of the cycle to attract mates and/or gain fertilizations, and feel relatively worse during the premenstruum.


But under conditions unfavorable to successful immediate reproduction, women are expected to lack the heightened positive states during the fertile phase of the cycle; therefore they will not feel relatively worse during the premenstruum – that is, they will not experience PMS
