Adolescent Sterility and Time required becoming Susceptible for Conception

Abstract

The interval between marriage and first conception leading to a live birth plays an important role in determination of fertility of a female. One of the proximate determinants of natural fertility is fecundability, which is defined as the probability of conception that a married female will conceive during a month of exposure under unprotected cohabitations. Thus, waiting time to first conception is used to study the fecundability, adolescent sterility and the time required to become susceptible for conception. In this study, real data sets are used to check the suitability of the model and for estimation of parameters, maximum likelihood method has been used. Also an attempt has been made to show the relation ship between adolescent sterility and time require to be ready for the conception. Inverse relationships between them have been observed. The estimate of fecundability is 0.041 for the first data set (1969-70) and 0.057 for the second data set (2014-15) however the estimate of adolescent sterility is higher for first data set than second data set.
