Abstract
Leukocyte-poor platelet-rich plasma (LP-PRP) has a potential influence on tissue regeneration by stimulating the proliferation and differentiation of progenitor cells. The aim of this work is the morphological assessment of spermatogenesis under the influence of growth factors after electron irradiation. Materials and methods Experimental animals (n = 135) were divided into 5 groups: I – control (n = 10); II – 2IR (n = 35; 2 Gy); III – 2IR + LP-PRP + IGF-1 (n = 30); IV – 2IR + LP-PRP (n = 30); V – LP-PRP (n = 30). Results Electron irradiation reduces the number of germ cells in comparison with the control group. After injection of LP-PRP + rhIGF-1 significantly increased the number of germ cells, Sertoli and Leydig cells, the height of germinal epithelium, area and diameter of seminiferous tubules. Conclusion LP-PRP + rhIGF-1 has a normalizing effect on structural and functional disorders of the testis caused by electron irradiation.
