Resumo: The article presents preliminary data from a prospective investigation in a sample of healthy 14-17-year-old students from a technical school in Sao Paulo, Brazil. Ninety-six Tanner stage 5 and thirty-one Tanner stage 4 adolescents were evaluated: testicular volume was measured using a Prader orchidometer, and semen analysis was performed according to standard procedures. Median testicular volume was 20.0ml among Tanner 5 students and 15.0ml in Tanner 4 students in both the right and left testes. No significant differences were found in sperm volume or motility. Median concentration was 66.0 million/ml for Tanner 5 and 47.0 million/ml for Tanner 4 subjects. Morphological patterns showed abnormal forms in 81.9% of Tanner 5 and 93.6% of Tanner 4 adolescents. Oligospermia (sperm concentration < 5 million/ml) was observed in 7.3% of Tanner stage 5 and 12.9% of Tanner stage 4 individuals. Azoospermia was observed in 3 students (1.8%), with counts less than 1.0 in 8 students (4.8%). The authors discuss the observed results, analyzing the potential implications arising from biological development and potential environmental exposures.

Foram avaliados 96 adolescentes estágio Tanner 5 e 31 estágio Tanner 4: o volume testicular foi medido utilizando um orquidômetro de Prader, e o espermograma foi realizado de acordo com os procedimentos padronizados. O volume testicular mediano, tanto direito quanto esquerdo, era 20,0ml nos alunos Tanner 5 e 15,0ml nos alunos Tanner 4. Não foram constatadas diferenças significativas no volume ou motilidade espermática. A concentração mediana era 66,0 milhões/ml para Tanner 5 e 47,0 milhões/ml para Tanner 4. Os padrões morfológicos evidenciaram formas anormais em 81,9% dos adolescentes Tanner 5 e 93,6% dos Tanner 4. A oligospermia (concentração espermática < 5 milhões/ml) foi observada em 7,3% dos indivíduos Tanner 5 e 12,9% dos Tanner 4. A azoospermia foi observada em 3 alunos (1,8%), além de uma contagem abaixo de 1,0 em 8 alunos (4,8%). Os autores discutem os resultados observados, analisando as implicações para o desenvolvimento biológico a partir de possíveis exposições ambientais.Reports in Public HealthCadernos de Saúde Pública2002-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfhttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/1685Reports in Public Health; Vol. 18 No. 2 (2002): March/AprilCadernos de Saúde Pública; v. 18 n. 2 (2002): Março/Abril1678-44640102-311Xreponame:Cadernos de Saúde Públicainstname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZenghttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/1685/3358https://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/1685/3359Mori, Marcos MitsuyoshiCedenho, Agnaldo PereiraKoifman, SergioSrougi, Miguelinfo:eu-repo/semantics/openAccess2024-03-06T15:26:34Zoai:ojs.teste-cadernos.ensp.fiocruz.br:article/1685Revistahttps://cadernos.ensp.fiocruz.br/ojs/index.php/csphttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/oaicadernos@ensp.fiocruz.br||cadernos@ensp.fiocruz.br1678-44640102-311Xopendoar:2024-03-06T13:01:58.729880Cadernos de Saúde Pública - Fundação Oswaldo Cruz (FIOCRUZ)true
