Busulfan is known to cause several adverse effects including reproductive toxicity in humans. Garlic (Allium sativum), a widely distributed medicinal plant, is highly regarded for its medicinal activities including antioxidant property.This study was conducted to assess whether garlic extract could serve as protective agents against testicular toxicity during busulfan treatment in a mice model.Seventy-two adult male mice were randomly divided into nine groups. In groups 1,2 and 3, distilled water, busulfan, and dimethyl sulfoxide and in the treatment groups hydro-alcoholic extract of garlic was administered orally at different doses per day (groups 4, 5 and 6; 200, 400, 800 mg kg-1 respectively). Groups 7, 8 and 9 were treated with the extract (200, 400 and 800 mg kg-1, respectively) plus busulfan. Following euthanasia, blood samples and epididymal sperm were collected.The busulfan-treated group showed significant decreases in sperm qualityparameters, and serum levels of testosterone, LH and FSH was observed in the busulfan-treated mice. In addition, the TAC levels and antioxidant enzymes activities were reduced and malondialdehyde (MDA) levels were increased in the busulfan-treated mice. Notably, garlic extract co-administration caused a considerable recovery in sperm qualityparameters, TAC levels, antioxidant enzymes activities, hormonal changes and MDA level. Based on our results, garlic has antioxidant effects against busulfan-induced testicular damages in mice.

The effect of modified vitrification was assessed on cellular development capability in mouse embryos cultured in vitro. In this study, 466 embryos (from zygote to morula stages) were vitrified then thawed embryos have been incubated for in vitro farther development up to blastocyst stage. Also, vitrification and thawing procedures were the same for all experimental groups. Mouse different embryonic cleavage stages were vitrified in ethylene glycol (EG) plus dimethyl sulfoxide (DMSO) and sucrose (VS-1) and EG plus DMSO (VS-2) and thawed by directly placing the vitrified drop into sucrose solution (TS) at 37 ˚C. High recovery (72–97%) of morphologically normal embryos was evident following vitrification and thawing. Development of the vitrified morulae into blastocysts (92%) was higher (p < 0.05). The amount of zygote and 2-cell stages that achieved to blastocyst stage was very low. With progressing the embryo cleavage to morula stage, the embryos that reached to blastocyst were increased to its maximum number. We concluded that the modified vitrification procedure supported better survival of morula stage compared to other cleavage stages in mouse embryos.

Side effects of ciprofloxacin (CPFX), a widely used broad spectrum antibiotic with fluoroquinolone core, have been reported in different organs. In the present study we sought to elucidate the impact of ciprofloxacin on sperm chromatin integrity and sperm DNA damage using Aniline Blue and Acridine Orange technique, respectively. The fertility potential in male mice was also evaluated. NMRI male mice of 8-week old were included in this study and they were randomly divided into three groups. The first group was received low dose (LD) of ciprofloxacin (206 mg kg-1, PO) and the second was treated with high dose (HD) of ciprofloxacin (412 mg kg-1, PO) for 45 consecutive days. The control mice were only treated with oral carboxymethyl cellulose for 45 consecutive days. Sperm cells were removed from cauda epididymis and analyzed for chromatin integrity and DNA damage. In addition, the rate of fertilization, two cell embryos, blastocysts, arrested embryos and their types was examined using zygotes cultured in human tubal fluid - bovine serum albumin (HTF-BSA) medium. Concomitant significant increase in DNA damage and protamine deficiency of the sperm cells in ciprofloxacin treated mice were observed (P < 0.05). In addition, the fertilization rate and embryonic development in treated mice were significantly lower than that of control mice, but the embryo arrest rate in treated mice was significantly higher than that of control group (P < 0.001). In conclusion CPFX was able to induce DNA damage and chromatin abnormalities of sperm cells which could be contributed in the observed low fertilization rate and retarded embryonic development.
