There have been many claims of aphrodisiac and other beneficial attributes of Azanza garckeana fruit by both tradomedicinal practitioners and some early scientific investigations; the present study, thus, set out to investigate the changes in reproductive hormones following administration of hydroethanolic extract of azanza garckeana fruit (HEAGF) in cadmium chloride exposed female Wistar rats. Thirty five (35) female Wistar rats weighing 230±10 grams were divided into 7 groups of 5 rats each. Group 1 served as negative control that received 1ml of distilled water; Group 2 served as positive control and received oral dose of 10mg/kg body weight of CdCl2 (or Cd); Group 3 had Clomiphene citrate (0.3mg/ml) + Cd; Group 4 received Vitamin E (0.3mg/ml) + Cd; Group 5 received 250mg/kg HEAGF+ Cd; Group 6 received 500mg/kg HEAGF+ Cd and Group 7received 1000mg/kg HEAGF+ Cd. All treatments were done orally and daily for 28 days.  Blood samples were collected, and serum levels of reproductive hormones including estrogen, progesterone, follicle-stimulating hormone (FSH), and luteinizing hormone (LH) were measured using ELISA and spectrophotometric technique. The results showed that CdCl2 exposure significantly (P<0.05) decreased FSH level but non-significantly (P>0.05) decreased LH level while increasing oestrogen and progesterone levels compared to the negative control group. However, administration of HEAGF, especially the 250mg/kg bw dose most appreciably restored the hormonal balance towards normal levels. In conclusion, although, the findings of the present study highlights the potential therapeutic value of HEAGF in improving the adverse effects of an environmental toxin―CdCl2 on female reproductive health indicators, further studies may be necessary to elucidate the underlying mechanisms of action prior to its clinical exploration and possible recommendation for supplementation in reproductive disorders associated with a heavy metal toxicity.
