Fertility awareness is experiential learning about cyclic fertility. This awareness, used as a family planning method, differs from contraception because it does not isolate the procreative capacity of either partner. The acceptability and effect of teaching fertility awareness on teen sexual activity and decision making was tested in a multisite pilot program which taught fertility awareness via the prospective marker of the cervical mucus (ovulation method of natural family planning). 200 US and 35 Guatemalan volunteer women ages 15-17 in a structured 1 year curriculum, monitored cycle charting and explored the implications of experiencing one's signs of fertility. Control subjects were recruited from the general population and from family planning clinics. 9% of the US study group were sexually active prior to entry. By cycle 12, 1/2 had discontinued activity. Conception rate was 0.0044. The continuation rate dropped from 90% at cycle 7 to 71% at cycle 8 due to scheduling constraints for 2 classes and to 57% at cycle 12. Postprogram follow-up of early leavers showed only 1/3 the expected rate of onset of sexual activity and pregnancy. Parent involvement correlated positively with postponement and/or discontinuation of sexual activity. Reported movement away from peer group pressure appeared 3 months after entry.
