A new method of culturing Leydig cells and prospects of their practical use in andrology.

We present a new method of obtaining a xenoculture enriched with Leydig cells from neonatal porcine testes providing 97-99% viability of cells in the culture. Genital extra-testicular transplantation of the obtained xenoculture was applied, which minimized traumaticity of surgery and the number of postoperative complications and had undoubted advantages over the subcapsular cell culture depot.
