ABSTRACT

The prevalence of female infertility ranges from 7 to 28% depending on the age of the woman. Although the origin and frequency of infertility vary about 40 to 50% of the aetiology of infertility cases is as a result of female factors. Malaria and the treatment of malaria have being a major challenge for decades. A number of antimalarial drugs have been reported to have anti-fertility actions. Amodiaquine (AQ) is an anti-malarial drug and belongs to a class of drugs known as the 4-aminoquinolines. It was removed from the essential drug list in 1990 as a result of hepatoxicity and agranulocytosis that occurred with long- term use. AQ is now making a comeback and is in the spotlight as a partner drug with artemisinins in the World Health Organization (WHO) recommended artemisinin based combination therapies (ACTs). In malaria-endemic regions of the world, self medication with antimalarial drugs is common and it is possible for a person to be treated several times in a year. With the frequency of treatment the risk of adverse events associated with long-term use of AQ may arise. A number of investigators have carried out studies on the effect of AQ on pregnancy and pregnancy outcomes, however, there remains a dearth of literature on the shortterm or long-term effect of AQ on the structure and function of the ovary in the nonpregnant female. This study was carried out to investigate the histomorphological changes and responses of the ovary of Sprague-Dawley rats to AQ administration. The study was divided into 4 experimental groups. AQ was given at a dose of 6.0 and 12 mg/kg bw via oral and intraperitoneal routes for 28 days. Vitamin C was administered at a dose of 0.1 mg/kg bw 3 days in a week while Vitamin E was given at a dose of 20 mg/kg bw 5 days in a week. In each of the experiments AQ was administered alone, co-administered with xviii Vitamin C and co-administered with Vitamin E (AQ alone, AQ + Vitamin C and AQ + Vitamin E) according to the treatment protocol. At the end of the experiment all the animals were sacrificed by cervical dislocation
