Evidence has shown that two hundred million pregnancies occur annually, of which 50% are unplanned while 25% unwanted. Contraception is a vital aspect of reproductive health and plays a key role in the prevention of unwanted pregnancy. To determine the type of contraceptive usage and some haematological indices of women on contraceptives. This study comprised 200 healthy female subjects [50 non-contraceptive users (group A), 50 non-hormonal contraceptive users (Group B), 50 progestin- only users (group C) and 50 combined contraceptives users (group D)]. A structured questionnaire was used to obtain the socio-demographic data of the participants. Four (4)mL of venous blood was collected from each participant into a pre-labeled di-potassium ethylene diamine tetra-acetic acid (K,EDTA) container and the samples were analyzed for haematological indices using a three parts ERMA haematology autoanalyser PCE-210N. Data analysis was carried out using the statistical package for social sciences (SPSS) version 17.0 software. Majority of the participants were married (88%) with 12% unmarried. The Mean ± SD HGB (g/dL), HCT (%), MCV (fl), MCH (pg), and MPV (fl) in group B subjects were significantly higher compared to group A (p<0.05). There was a statistically significant decrease in the HGB, HCT, MCV, MCH and MPV values of Group A compared to Group C (p<0.05). The mean values of HGB, HCT and MCH among group D were statistically significantly higher compared to group A (p<0.05). The use of contraceptives has an effect on haematological indices with variations depending on the type of contraceptive.
