| Abstract: |
Several studies have assumed that fecundability of female is constant over time except the early reproductive ages i.e., <=15 years. In this paper, an attempt has been made to test this hypothesis since in spite of being a biological factor, fecundability is also governed by a large number of socio-demographic and cultural factors associated with it. In the present study, fecundability is estimated for India as well as different major states of the country in different age-groups of the females using the data of their last closed birth interval. The relevant data are compiled from the National Family Health Survey III. Life table technique is used to estimate age specific fecundability to statistically grip the problem of censoring and selectivity. The results show that fecundability decreases with increasing age of the females. But, from this it cannot be inferred that age is the only factor responsible for variation in fecundability. This may be due to some socio-cultural factors which influence the behavioural factor, coital frequency. This study suggests that the variation in fecundability among the Indian females is due to the confounded effect of age and some socio-cultural factors associated with coital frequency and the effect of these two cannot be separated.
