Estrogen and testosterone are considered as male and female hormones, although, both hormones are produced in both sexes, the estrogen is produced by male reproductive organs in various species. The present study was conducted to determine the effect of exogenous estrogen (Diethylstilbestrol) on sexual behavior and libido of Kundhi buffalo bulls. Four Kundhi buffalo bulls of aged 5-6 years kept under good managemental conditions were chosen for the study, the animals were divided into two groups, group-1 having three numbers of bulls treated as experimental animals and internal control as well, and fourth bull was kept as an untreated external control. 20mg of Diethylstilbestrol was injected intramuscularly to each experimental bull, the intensity of sexual behavior, number of false mounting, degree of intromission and erection were observed in individual bull during semen collection for period of 12 weeks with frequency of 4 ejaculates in a week. The collected qualitative data was converted in numeric and score of 1-3 was given according to intensity of particular parameter. The quantified number of false mounting, sexual excitement, degree of erection and intromission in control versus experimental animals were 1.73 vs. 1.90, 1.58 vs. 1.77, 1.66 vs. 1.52 and 1.58 vs. 1.55, respectively. It was concluded that the exogenous estrogens has little impact on sexual behavior in experimental animals. These results indicate that the administrated exogenous estrogen might be utilized by the estrogen receptors present in brain and other various tissue of the body which result in stimulation of sexual excitement.
