This cross sectional study was designed to evaluate the knowledge and actual practice of condom-usage amongst sexually active undergraduates in tertiary institutions. A total of 300randomly selected students (150 males and 150 females) of three Nigerian tertiary institutions and within the age range of 15 and above, were involved in this study. Data collection was performed using a pre-tested questionnaire and the result revealed that despite having knowledge about condom, there were low practice of condom-usage with little or no regard for Sexually Transmitted Infections (STIs) and unwanted pregnancies. This finding suggests that there is an urgent need to address the low practice of condom-usage among sexually active undergraduates in tertiary institution with focus on the importance of engaging in safer sexual behavior in other to curb the menace of abortion and the chances of acquiring STIs among sexually active undergraduates.Keywords: Abortion, Condom-usage, Knowledge, Practice, Undergraduat
