[Experimental research on prespermatogenesis].
The author carried out experimental studies on prespermatogenesis, using 20 rats of Wistar strain, divided into the following groups: newborns, on the 5th, 10th and 15th day after delivery. Histomorphological study of the testicular tissue was made as two basic cellular types--germinal and Sertoli's cells in seminal cords of prepubertal period of the development of the rat were examined. The performed morphological characteristics of germinal and Sertoli's cells during the period of prespermatogenesis of the rat showed the existence of parallelism in the differentiation of the two types of cells. This parallelism and balance between the two types of cellular populations affects later on the normal formation and function of spermatogenesis, which is of substantial significance for the fertile possibility of individuals.
