“…In the higher doses like 2 and 4 mg L −1 groups, the antioxidant levels were decreased, and simultaneously, ROS levels were increased which led to severe DNA damage in the spermatozoa. This difference in ROS relative to the antioxidant system of spermatozoa can potentially result in metabolic or functional disorders and reduction in sperm motility (Li et al 2009). The relatively high polyunsaturated fatty acid content of the spermatozoon membrane makes it susceptible to oxidative damage (Trenzado et al 2006).…”

Effects of tributyltin (TBT) on antioxidant [total superoxide dismutase (SOD), glutathione peroxidase (GPx), and glutathione reductase (GR)] and DNA damage levels in the spermatozoa were studied and reported here for the first time in the freshwater prawn Macrobrachium rosenbergii. Three groups of (n = 10 in each group) fishes were exposed to three different nominal concentrations of TBT viz., 1, 2, and 4 mg L(-1) along with control group for 90 days. Significant decrease of antioxidant and increased DNA damage levels were seen at higher doses of 2 and 4 mg L(-1). In prawn, the antioxidant level plays a vital role in sperm protection, activation, differential functions related to the physiology, and reproductive behavior. This study serves as a biomonitoring tool to assess the TBT effects on reproductive behavior of aquatic biota.

“…An increase in oxidative stress can cause metabolic or functional disorders of spermatozoa reducing sperm motility (Li et al, 2009). S. birrea fruit and S. pepo seed have been shown to possess polyphenols and high antioxidant activity (Borochov-Neori et al, 2008; Steinberg, 1991; Kunyanga et al, 2012).…”

Background: Any substance that increases erectile function, sexual performance and enjoyment is considered an aphrodisiac. The aim of this study was to compare the effects of food plants Mondia whitei, Chenopodium album, Cucurbita pepo and Sclerocarya birrea extracts at a fixed dose of 200mg/kg body weight on sexual behavior, sperm parameters and testosterone levels in adult male rats. These are food plants also traditionally used as aphrodisiacs in South Africa, Zimbabwe and other parts of Africa. Materials and methods: Sexual behavior parameters assessed in this study included an arousal component (mount latency and intromission latency); sexual potency (mount frequency and intromission frequency), erection (copulatory efficiency) and ejaculations. All treatments were administered orally daily for 28 days. Sexual behavior parameters were quantified 2 hours after a single dose, at 14 days and at 28 days of treatment. Results: The order of efficacy in stimulating sexual behavior in male rats was M. whitei >S. birrea > C. pepo ≥ C. album. Although there was no change in number of ejaculations and sperm count (P>0.05) for all treatment groups compared to controls, all treatments increased (P<0.05) sperm motility. M. whitei and C. pepo treatments resulted in increased (P<0.05) serum testosterone levels. Conclusion: Therefore, this study demonstrates varying aphrodisiac activities of food plants used traditionally as aphrodisiacs.

“…Assessment of the composition and functions of enzymes of semen provides new insights into spermatozoa motility and fertilizing abilities, via creating possibilities for improving artificial reproduction and germplasm resource conservation procedures (Li et al 2008). Studies on the enzymatic status of fish semen are specialized and are limited to a few enzymes.…”

An important aspect in the management and protection of endangered species from extinction is the determination of normal physiological values, including the blood and seminal plasma properties. This study was undertaken to establish a reference range for six important blood and seminal plasma enzymes. Samples of 20 Acipenser persicus Borodin, 1897 (10 female and 10 male) were analyzed. The reference ranges for the total samples and also for each sex were determined. The activities of measured enzymes in blood and semen were: alkaline phosphatase (ALP, 363.2 ± 25.24 and 12.23 ± 3.66 IU/L), acid phosphatase (ACP, 4.98 ± 0.39 and 1.86 ± 0.71 IU/L), lactate dehydrogenase (LDH, 1978.8 ± 176.5 and 472 ± 138.7 IU/L), creatine kinase (CK, 1149.6 ± 110 and 553.8 ± 119.9 IU/L), aspartate aminotransferase (AST, 51.12 ± 3.5 and 2.29 ± 1.34 IU/L) and alanine aminotransferase (ALT, 14.7 ± 0.89 and 6.9 ± 2.5 IU/L), respectively. There were significant differences between male and female fish in terms of LDH, CK and ALT activity (P < 0.05). To detect relationships among investigated parameters we used the Pearson correlation coefficient; no significant correlations were observed between these parameters in either blood or seminal plasma.
