The analysis of spermatid, spermatocyte and spermatogonia in the central zones of seminiferous tubules revealed that mature cell percentages in low dose groups were higher than both the high doses and the control groups (p less than 0.
Spermatogenic cell series in seminiferous tubule wall, spermatogonium, primary spermatocytes, spermatid cell, and Sertoli cell were found normal and comparable to the untreated control (Figure 4a-d).
Testosterone promotes the conversion of round spermatids between stages VII and VIII of the rat spermatogenic cycle.
Stained slides were assessed by light microscope by a person who had no knowledge of the category and with the following characteristics: Number of spermatogonia cells, primary spermatocytes, sertoli, leydig, spermatids, and spermatozoa.
parallelus have been quantified by analyzing the proportion of abnormal spermatids (morphology and size: aberrant, micro- and macro-spermatids) in pure populations of both subspecies and from infected and uninfected individuals from the hybrid Pyrenean population of Portalet (Fig.
The right testis and caudal epididymis were kept in saline buffer for spermatid and sperm counts, respectively.
Such chromatoid bodies persist throughout spermatogenesis until the spermatid stage, but their size and number is far higher in primary spermatogonia.
The production of step-19 spermatids was reduced by 87.
11 According to criteria 10 is complete spermatogenesis with many (greater than 5) spermatozoa; 9 means many (greater than 5) spermatozoa present but germinal epithelium disorganised with marked sloughing or obliteration of lumen; 8 is only a few (less than 5) spermatozoa; 7 is no spermatozoa but many spermatids (greater than 5); 6 is no spermatozoa only a few (less than 5) spermatids; 5 is no spermatozoa or spermatids but many spermatocytes (greater than 5); 4 is no spermatozoa or spermatids and only a few spermatocytes (less than 5); 3 is spermatogonia only germ cell present; 2 is no germ cells but sertoli cells are present; 1 no cells in tubular section.
In testis, tyrosine phosphorylation is assumed to have the roles in spermatogenesis and testosterone synthesis because these proteins have been localized in the sustentocytes and elongated spermatids (Arad-Dann et al.
Differences in diameters of spermatogenic (spermatogonium, spermatocyte, spermatid, and spermatozoa) and oogenic stages (oogonia, previtellogenic oocyte, vitellogenic oocyte, and postvitellogenic oocyte) between diploids and tetraploids were analyzed by means of analysis of variance (Statistica v.
