Article Details
While African Health Sciences has been freely accessible online there have been questions on whether it is Open Access or not. We wish to clearly state that indeed African Health Sciences is Open Access. There are key issues regarding Open Access needing clarification for avoidance of doubt:
- 1. Henceforth, papers in African Health Sciences will be published under the CC BY (Creative Commons Attribution License) 4.0 International. See details on https://creativecomons.org/)
- 2. The copyright owners or the authors grant the 3rd party (perpetually and in advance) the right to disseminate, reproduce, or use the research papers in part or in full, format/medium as long as:
- No substantive errors are introduced in the process
- Attribution of authorship and correct citation details are given
- The referencing details are not changed.
Should the papers be reproduced in part, this must be clearly stated.
- 3. The papers will be freely and universally accessible online in an easily readable format such as XML in at least one widely recognized open access repository such as PUBMED CENTRAL.

Effects of aqueous extract of Moringa oleifera seed on cadmium-induced reproductive toxicity in male Wistar rats
Abstract
Objective: Cadmium is a heavy metal that induces reproductive toxicity. To elucidate its possible mechanisms of action, the effects of aqueous extract of Moringa seeds (AEMS) on Cadmium-induced reproductive damage were investigated.
Methods: Thirty male rats (180-200g, n=5) were grouped as follows: Control, Cadmium (2mg/kg), AEMS (100 and 500mg/kg), Cadmium+100mg/kg AEMS and Cadmium+500mg/kg AEMS. Single intraperitoneal dose of Cadmium was administered while AEMS was given daily (p.o) for 6 weeks and thereafter sacrificed by cervical dislocation. Sperm variables were examined microscopically while serum was analysed for sex hormones and antioxidants, testicular and epididymal total protein from tissue homogenate. Data were analysed using Students t-test and ANOVA.
Results: Cadmium caused significant decrease in sperm variables. The AEMS decreased sperm motility, count and testosterone. These declines were dose dependent. Total testicular protein was significantly lowered by AEMS but total epididymal protein was not affected. Serum catalase and SOD was reduced by AEMS while MDA increased.
Conclusion: Moringa seeds may exhibit male reproductive toxicity, as observed from its deleterious effect on androgen and sperm variables. It failed to prevent cadmium-induced alteration in reproductive variables and serum antioxidants.
Keywords: Aqueous extract, Moringa oleifera seed, cadmium-induced reproductive toxicity, male Wistar rats.
