At some point each of us asks ourselves with awe for the first time, “Where did I come from?” It has been said of the body that it is “fearfully and wonderfully made.” How true this is of the reproductive systems on which the survival of our species depends.

  • The most commonly used measures of current fertility are the total fertility rate (TFR) and its component age-specific fertility rates (ASFRs). The TFR is an estimate of the average number of births a woman would have at the end of her reproductive years if she bears children at the prevailing age-specific fertility rates throughout her childbearing years (age 15-49). The ASFRs are defined in terms of the number of live births among women in a particular age group divided by the number of woman-years in that age group during the specific period. Figure 4.

  • Recent studies have shown that differences in life history may lead to consistent inter-individual variation in behavioural traits, so-called behavioural syndromes, animal personalities or temperaments. Consis- tencies of behaviours and behavioural syndromes have mainly been studied in non-cooperative species. Insights on the evolution of coopera- tion could be gained from studying individual differences in life histories and behavioural traits.

  • Several clinic-based programs have been evaluated with experimental designs and three (out of five) of them showed some positive impacts on reproductive health outcomes (Danielson et al., 1990; DeLameter et al., 2000; Orr et al., 1996). Those programs that showed positive impacts included one-on-one counseling and delivered a clear message about appropriate reproductive health behaviors (Kirby, 2001).
