“…Groups 3 and 4 showed normal central vessels that were not congested, on the other hand, group 5 showed mildly congested central vessels, the sinusoids appeared normal and not infiltrated by inflammatory cells. This finding agrees with a similar study by Khater (1998) in studying the effect of different doses (15, 30, 60, 90 mg) of 17α-methyltestosterone on the liver for 28 days and indicated that the hepatic parenchyma had diffused vacuolar degeneration while the central veins and hepatic sinusoids were congested, on the contrary, Deborah, (1990) and Kefi et al (2013) found that there was no deviation from the normal morphology in livers. However, in this study, there appeared to be differences in the hepatocytes, abundant glycogen vacuolation in groups 2 and 4.…”

“…There have been reports that hormones excreted by treated fish from undigested feeds can build up in a closed water system; accumulate in water residue and aquatic biota (Dauda et al, 2014). Kefi et al (2013) in their trial with tilapia fish, observed an induced sex inversion in waters not directly applied with methyltestosterone, although is not well understood; the effect on water pollution.…”

“…Nonetheless, hematological indicators of the fish's nutritional condition and general health have been said to be reliable (Katalay & Parlak, 2004) [31] , as they indicate the nutritional status and overall health of the fish (Akinrotimi et al, 2012) [32] . The fall in Ht and Hb of the fish after MT delivery may indicate that their condition has worsened as a result of the androgen therapy (AS & J, 2013) [33] . According to Joshi et al, 2002 [34] , fish may be less able to increase their activity to fulfil sporadic needs if their haemoglobin levels are lower.…”
