Introduction: Unintended pregnancies can occur during unprotected sex, contraceptive failure, or as a result of rape. They typically occur among adolescent girls, particularly schoolchildren, and are a worrying phenomenon that continues to crack down many African countries.

Objective: To describe the extent of unintentional pregnancies in schools in the two regions of northern Togo.

Method: This was a descriptive and cross-sectional study that took place from december 26, 2024 to July 3, 2025 in secondary schools in the communes of Kozah 1 and Tchaoudjo covering the current academic years from 2020 to 2025. The study population consisted of all students enrolled or having dropped out of classes in the targeted establishments, who had experienced pregnancy during their school career and students who were pregnant at the time of the study from the year 202 0 to 2025 who had given their consent. Data analysis was done using epi info 7 software and Microsoft Excel 2016.

Results: A total of 122 middle and high school girls from 31 schools participated in the study. The age group of 19 to 23 years represented 48.3% with extremes of 11 years and 23 years. Those who were between 15 and 19 years represented 43.4%. The average age of the students was 19 years. High schools located in the heart of the 2 cities had recorded more pregnancies. Girls in high school represented 63.7% (n = 116) and those in middle school represented 36.3% (n = 66). Students in the final year of high school represented 33% (n = 60). They lived in rural areas (54.9%) and in close quarters (59.3%) receiving less than €0.76/day from their parents. Among these students, 47.8% were more than 5 km from schools and walked there (81.9%). Most (96.1%) were informed about contraceptive methods and used them in 47.3% of cases. The perpetrators of pregnancies were pupils (34.6%), students (28%) and teachers (3.8%). Illegal induced abortions represented 19.8% and 9.3% of students dropped out of school.

Conclusion: The study on the epidemiology and factors associated with unintentional pregnancies in schools in these two regions has highlighted some associated factors linked to the occurrence of pregnancies among young girls in school.
