[Development of seminiferous tubules in guinea pigs during puberty].

The study of development of the seminiferous tubules of the guinea-pig along the puberty is based on diameter, length and volume relate to testicular weight and age. During this period the development is linear. A correlation exist between testicular testosterone concentration and growth of seminiferous tubules in diameter and in length from day 16 to 60, stage of puberty in which the first spermatozoa appear.
