Despite the abundance of studies on unplanned pregnancy and the fact that the high incidence remains a major public health concern worldwide , the dominant focus tends to be on the vulnerabilities of young women of low socio-economic status and those with little or no formal education [2, 3]. Even so, the association between perceived unplanned pregnancy-risks and the use of emergency contraception remains unclear, as studies on this subject tend to focus mainly on EC effectiveness as well as knowledge, attitude and practices of EC. This article draws on the findings of a survey conducted in two Nigerian universities to shed light on the sexual behaviour of female undergraduate students and the dynamics of emergency contraceptive use among this cohort of students.
