A degeneracao seminal ocorreu em todos os animais na 4a. semana apos o inicio da insulacao, ressaltando-se a reducao na concentracao, o aumento dos defeitos espermaticos e a reducao do vigor celular, culminando com a necrospermia. A motilidade individual progressiva(MIP) atingiu os valores mais baixos na 3a. semana apos o inicio da insulacao, retornando aos valores normais entre a 8a. e 9a. semanas. Os defeitos espermaticos comecaram a aumentar aos sete dias apos o inicio da insulacao escrotal. O volume apresentou oscilacoes atipicas e o aumento da temperatura escrotal afetou os parametros fisicos e morfologicos do ejaculado de maneira consistente evidenciando-se o efeito negativo sobre a qualidade do semen.  [Scrotal testicular and semen parameters in adult male goats submitted to scrotal insulation]. Abstract: Ejaculations of twelve adult bucks, six Moxotó breed and six crossbred 1/2 Moxotó-Alpine Brown, kept in confinement were evaluated prior to and after insulation of scrotal sac through a plastic bag with double wall for 6.5 days. There was seminal degeneration in all animals, showed by reduction of spermatic concentration and drop of the forward individual motility (MIP) associated to high level of sperm morphological abnormalities and hence necrospermy. The MIP reached lower values in three weeks after beginning of the scrotal insulation when sperm vigor was also reduced and sperm abnormalities increased. Seminal degeneration occurred on the 4th week post-insulation. However, within 56-63 days post-insulation the MIP returned to normality. The sperm abnormalities began to appear seven days after the initiation of insulation. The semen volume oscillated during all experimental period and the increasing heat in the scrotal sac caused a series of physical and morphological changes on seminal cells that altered the semen quality.  aBrazil  aGoats  aSeminal plasma  aCaprino  aSêmen  aBrasil  aCeara  aConsistência testicular  aDegeneracao seminal  aMorfologia espermática  aPerímetro escrotal  aPlasma seminal  aScrotal circumference  aSeminal degeneration  aSperm abnormality  aSperm morphology  aTesticular consistency1 aSIMPLICIO, A.
