O volume apresentou-se com oscilacoes atipicas e o aumento da temperatura no escroto afetou as caracteristicas escroto-testiculares e do ejaculado de modo consistente. Os defeitos espermaticos comecaram a elevar-se aos sete dias apos o inicio da insulacao. A motilidade individual progressiva atingiu os menores valores a terceira semana apos o inicio da insulacao, retornando aos valores normais entre a oitava e nona semanas. Entretanto, a degeneracao seminal ocorreu em todos os animais na quarta semana apos iniciado o desafio  escroto-testicular todos os animais mostraram regeneracao do perimmetro escrotal, da consistencia testicular e do quadro espermatico.  [Scrotal-testicular and ejaculation characteristics in crossbred bucks submitted to scrotal insulation]. Abstract: The scrotal sac and ejaculation characteristics of adult crossbred, Moxoto-Alpine Brown half-breed, were studied before and after scrotal insulation using plastic bag of double wall during 61/2 days. Scrotal insulation consistently affected all ejaculate and scrotal sac characteristics. Sperm morphological abnormalities began to appear seven days after scrotal heat stress. The forward progressive motility reached the lowest values at the third week after starting insulating and returned to normal values by the eighth and ninth weeks. However, seminal degeneration was completed in all animals at the fourth week after beginning of thermal injury, showing reduction of spermatic concentration, increase in morphological sperm abnormalities, and reduction in cellular vigor, culminating with the occurrence of acnesy and necrospermy. However, 10 weeks after thermal scrotal injury all animals showed scrotal circumference, testicular consistency and spermatic picture regeneration.  aBrazil  aGoats  aMale genital diseases  aReproduction  aTestes  aBode  aCaprino  aReprodução animal  aSêmen  aTestículo  aBrasil  aCeará  aDegeneração testicular  aInsulação escrotal  aScrotal insulation  aTesticular degeneration1 aSIMPLICIO, A.
