ALLOTRANSPLANTATION OF CULTURED NEONATAL ANDROGEN-PRODUCING LEYDIGS CELLS

The paper describes the procedure for grafting the cultural neonatal androcen-producing Le dig's cells to the rat gonad, the status of the gonad and the graft in different periods following transplantation. The transplanted Leydig's cells preserve their structure within 6 months after allotransplantation. There is a normal spermatogenesis in the seminal canals. No phenomena of lymphoid infiltration, thrombosis of small vessels and other manifestations of histocompatibility were noted.
