Abstract
In a previous study, we evaluated the maternal and fetal safety of antimalarial herb Artemisia annua with artemisinin yield of 1.09%. Here, we attempted to ascertain the contraceptive claim of A. annua. Sexually matured female Wistar rats (180–220 g) were allotted into four study groups of six rats each. The control group received normal saline, while the A. annua-treated groups received 100, 200 and 300 mg/kg of A. annua for 2 weeks, followed by mating with proven fertile males (1:1). The rats were allowed to carry the pregnancy to term. At birth and weaning periods, selected reproductive outcome and fertility indices were determined. The results showed that A. annua significantly reduced litter size, reproductive outcome and fertility indices compared with the control (p < 0.05). These results imply that A. annua could serve as a prospective contraceptive agent in addition to its antimalarial activity.
