TL;DR
This study uses electron microscopy to examine the ultrastructure of bovine testes in calves and bulls, revealing developmental stages and cell types important for reproductive biology.
Contribution
The study identifies three distinct stages of seminiferous tubule development and describes two types of Sertoli cells in cattle.
Findings
Three distinct stages of seminiferous tubule development were identified in calves.
Two types of Sertoli cells, differing in electron density, were observed in cattle testes.
Morphological changes in pre-Sertoli cells during maturation were detailed using ultrastructural analysis.
Abstract
The detailed analysis of the structure of individual organs is necessary to understand the processes occurring within them. The complicated nature of male reproductive processes and the still insufficient knowledge of the structure of the male reproductive system prompted us to undertake the present research. In this study, using transmission electron microscopy (TEM) and histology staining, testes of sexually immature calves and reproductive bulls of the Polish Holstein-Friesian Black-and-White breed were analyzed. The obtained results were summarized and compared with previously published reports. The present manuscript presents complementary information on ultrastructure of seminiferous epithelium and interstitial tissue in cattle and provides an essential morphological background for further applied research. The purpose of this study was to analyze the ultrastructure of the testes…
