Abstract

The factors affecting ovulation interval, like another biological phenomenon are numerous and interdependent. This paper identified the factors to include Age, Height, Weight, Work Time (Stress), Menstrual Duration, Number of Conceptions, Number of Births and Exposure to Sun. It is the aim of this paper to formulate a smaller number of independent random variables such that minimum information is lost. A total of two hundred (200) women in their reproductive age interval were selected for the study. Questionnaires were used to get the relevant information from them. Eighty eight percent (88%) of the total variation in the ovulation interval was accounted for by six (6) principal components compared to the original eight random variables. It was observed that the most important factors are Stress, Height, Menstrual Duration, Weight and Age, and that only Exposure to Sun did not show any significance in affecting Ovulation Interval.
