Special Food and Nutrition Dept., Food Technology Research Institute, Agric. Res. Center, Giza, Egypt Email address: [email protected] Abstract:
Objective: To investigate whethervitamin E, selenium, β-carotene, anthocyanin and green tea extract have a
possible protective effect against azithromycin (AZ)-induced testicular dysfunction. Design: Experimental study.
Setting:Research Institute of Ophthalmology, Giza, Egypt.
Patient(s):3 -week-old weanling male albino rats (n = 54).
Intervention(s):AZ was administered to rats at dose of 20mg/kgbw orally for 3 days every two weeks.
Vitamin E, β-carotene pigment,anthocyanin pigment, green tea extract, Se as sodium selenite and their mixture were administered with AZ by gavage daily for 4 months. Main Outcome Measure(s):Body and reproductive organ weights, spermatozoal activity, fructose contents,
testosterone (T), interstitial cell-stimulating hormone (ICSH), lipid peroxidation and, antioxidant enzyme activities were investigated.Histopathological changes in reproductive organs examined. Result(s):Significant decreases in serum T and ICSH,reproductive organ weights, spermatozoal activity and
fructose content were recorded due to AZ administration, whereas these parameters increased the antioxidants-treated groups. A significant decrease in Testicular MDA level and marked increases in GSH- Px, SOD, and CAT activities were observed in rats treated with different antioxidants. However, the most positive treatment was Se-treatment and the mixture of vitamin E with β-carotene pigment. AZ-treatment led to adverse histopathologic changes in the testes, epididymis cuda, seminal vesicle and prostate, whereas normalhistopathological imageof the studied reproductive parts were observed in groups treated with Se, Vitamin E and β-carotene. Conclusion(s):Antioxidants have a protective effect against testicular toxicity caused by AZ. This protective
effect of the antioxidants seems to be closely involved with the suppressing of oxidative stress. Key words: Azithromycin; Antioxidants; Oxidative stress; spermatozoal activity; Testes.

Secondly, ROS directly damage sperm DNA,compromising the paternal genomic contribution to the embryo. Despite the common association between compromised sperm quality and oxidative damage, men are rarely screened for oxidative stress nor treated for this condition(23).
In more details, free radicals have the ability to directly damage sperm DNA by attacking the purine and pyrimidine bases and the deoxyribosebackbone. Normally, sperm DNA is tightly packaged by protaminesprotecting it from free radical attack. However, infertile men often exhibit deficient protamination, leaving the spermDNA particularly vulnerable to ROS attack (24). Alternatively,
free radicals can initiate apoptosis within the sperm, leading to caspase-mediated enzymatic degradation of the DNA Fig. 1. Azithromycin

4. Discussion
A review of literature suggest that antimicrobial agents can affect male reproductive functions including sperm counts, motility, morphology, spermatogenesis and germ cell integrity (35,29,52-55).Azithromycin is an azalide,
a subclass of macrolide antibiotics, structurally modified from erythromycin. Its efficacy and potential to inhibit microorganisms had led to its increased use. It is well- known that Azithromycin is widely used to treat or prevent certain bacterial infections, most often those causing middle ear infections, strep throat, pneumonia, typhoid, and Volume 2 2015 Issue 1 DEC-JAN AIJCSR ISSN 2349 – 4425 www.americanij.com sinusitis.
