“…Epididymal growth followed a parallel trend to testis development, as reported previously for Blackbelly ram lambs (10) ; the greatest relative epididymal growth was observed between 9 and 18 wk, which agrees temporally with the greatest rate of testicular growth in this breed (10,11) .…”

“…Esto coincide con los datos del estudio 1, donde los cambios en las características del perfil de LH fueron evidentes a esas edades, los cuales parecen ser eventos endocrinos importantes asociados con el proceso de pubertad. Estos cambios endocrinos están temporalmente asociados con el establecimiento de la espermatogénesis (14) y con el desarrollo y mayor tasa de crecimiento testicular en corderos Blackbelly (15) . En el presente estudio no se hicieron observaciones respecto al inicio de la pubertad; sin embargo, con base en estudios anteriores en condiciones similares (14) , la espermatogénesis comienza entre las 9 y 12 semanas de edad y se completa (basado en la presencia de espermátidas alargadas en la mayoría de los túbulos seminíferos) hacia las semanas 15 a 18, aunque no se haya alcanzado la máxima capacidad; por otra parte, bajo condiciones similares, se observó la presencia de espermatozoides en la cola del epidídimo a las 18 semanas de edad (28) .…”

“…This is in agreement with data from Study 1, where changes in the characteristics of LH profile are evident at those ages, which seem to be important endocrine events associated to the process of puberty. These endocrine changes are temporally associated with the establishment of spermatogenesis (14) , testis development and the greatest rate of testicular growth (15) in Blackbelly ram lambs. In the present study no observations were made regarding the puberty status; however, based on previous studies under similar conditions (14) , spermatogenesis starts between 9 and 12 wk of age and is completed (based on the presence of elongated spermatids in most of the seminiferous tubules) by wk 15 to 18, albeit not reached full capacity; furthermore, under similar conditions, sperms were present in the cauda epididymidis at 18 wk of age (28) .…”
