Abstract : The Degradation process model was found to be appropriate and fixed over the two bio-object frameworks: (i) Comparison among Low and High BMI, WC, OC consumption levels of Parous and Nulliparous women (ii) Profile of 17β-estradiol and progesterone against upper, middle and lower tertile. The author verified the results provided by the medical field and found that there is no significant connection between performance of Reliability function of Degradation process fixed for 17β-estradiol and progesterone and parity of the women. The monotonically increasing curves depicts that the Reliability function of Degradation process fixed for 17β-estradiol and progesterone over parous, nulliparous women have maximum performances over the women having high BMI (>25 Kg/m2) and who were consuming oral contraceptives more than 3 years. But interestingly we observed the inverted results over daily salivary observation against lower, middle and upper tertile as lower tertile with less than 10 ten years interval serves upper bound and upper tertile with 13.5 years’ time interval serves lower bound of middle tertile with interval 10 – 13.5 years.
