Early pubertal development induces early sexual activities among adolescents. In Ghana, despite the high sexual activity among Ghanaian adolescents, sexual and reproductive health (SRH) services are underutilised, primarily due to SRH stigma and a lack of SRH knowledge and information. This study examined the use of SRH services among adolescents aged 15-19 years in Ghana over a ten year period. The study utilised data from the 2007 and 2017 Ghana Maternal Health Surveys (GMHSs). Responses from 2056 and 4909 adolescent females captured in the 2007 and 2017 GMHSs, respectively, were used. The results showed a declining utilisation of SRH services among adolescents from 28.3% in 2007 to 22.5% in 2017. The odds of using family planning among sexually active adolescents increased from 2007 [AOR-0.32, CI-(0.135, 0.77), p < 0.001] to 2017 [AOR-68.62, CI-(36.104, 130.404), p < 0.001]. With increasing age at first sex, adolescents were less likely to use a family planning method in 2007 [AOR-0.94, CI-(0.89,0.99) p < 0.001], but this improved in 2017 [AOR-1.26, CI-(1.220, 1.293), p < 0.001]. Despite this, knowledge of sources for family planning was found to predict its lower utilisation in both 2007 [AOR = 0.15 (95% CI-0.081, 0.283), p < 0.0001] and 2017 [AOR = 0.206 (95% CI-(0.099, 0.426), p < 0.001]. The findings show that even though knowledge of family planning methods predicted low utilisation, knowledge of sources, age at first sex, and educational level positively predicted the utilisation of SRH services from 2007 to 2017. Opportunities for both enhancing the clinical environment and health provider attitudes exist and should be explored for improving SRH outcomes among sexually active adolescents in Ghana.
