A total of 14 young <jats:styled-content style=\"fixed-case\">B<\/jats:styled-content>arbarine rams were used. Seven animals were treated with three melatonin subcutaneous implants (<jats:styled-content style=\"fixed-case\">M<\/jats:styled-content>elatonin) on 28 <jats:styled-content style=\"fixed-case\">F<\/jats:styled-content>ebruary while the remaining rams remained untreated (<jats:styled-content style=\"fixed-case\">C<\/jats:styled-content>ontrol). After 60 days of melatonin administration, scrotal circumference reached average values of 32.1\u2009\u00b1\u20091.54 and 29.5\u2009\u00b1\u20091.0\u2009cm for <jats:styled-content style=\"fixed-case\">M<\/jats:styled-content>elatonin and <jats:styled-content style=\"fixed-case\">C<\/jats:styled-content>ontrol animals, respectively (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05). Semen characteristics did not differ between groups; melatonin treatment tended (<jats:italic>P<\/jats:italic>\u2009=\u20090.091) to increase sperm concentration 60 days after implantation when means reached 5.87\u2009\u00b1\u20090.703 and 4.61\u2009\u00b1\u20090.654\u2009\u00d7\u200910<jats:sup>9<\/jats:sup> spermatozoa\/mL for <jats:styled-content style=\"fixed-case\">M<\/jats:styled-content>elatonin and <jats:styled-content style=\"fixed-case\">C<\/jats:styled-content>ontrol rams, respectively. Melatonin treatment significantly affected total activity time, number of lateral approaches and mount attempts in comparison to controls. During a 6\u2010h sampling period, mean plasma testosterone concentrations increased as a result of melatonin treatment (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001) and testosterone pulse frequency averaged 3.45\u2009\u00b1\u20092.24 and 1.25\u2009\u00b1\u20091.0 (<jats:italic>P<\/jats:italic>\u2009=\u20090.086) for <jats:styled-content style=\"fixed-case\">M<\/jats:styled-content>elatonin and <jats:styled-content style=\"fixed-case\">C<\/jats:styled-content>ontrol rams.
