La regulación de la fase postnatal temprana de activación testicular así como de la posterior quiescencia en humanos es poco conocida. Tanto la secreción de hormonas hipofisarias como la composición celular del testículo correspondiente a la fase postnatal temprana son diferentes al testículo adulto. El objetivo fundamental del presente trabajo de tesis fue desarrollar el cultivo primario de células testiculares humanas provenientes de necropsia. Se estudiaron 50 testículos de pacientes neonatales (grupo 1, G1), de la etapa de activación postnatal (G2), de la etapa de quiescencia testicular (G3) y puberales (G4). El estudio de la secreción de testosterona (T), marcador de células de Leydig, en función del tiempo post mortem (tpm) encontró q...
