 [sper″mah-to-go´ne-um] (Gr.)
an undifferentiated male germ cell, originating in a seminal tubule and dividing into two spermatocytes.

sper·ma·to·go·ni·um

According to photomicrograph and comparison of seminiferous tubule cross sections among experimental, control and sham groups, there was no tissue changes in spermatogonium, primary spermatocyte and other cells in terms of size, numbers, cytoplasm characteristics, nucleus and their staining.
In males, examination of nuclear characteristics and cell size revealed that the germ cells could be classified into four stages: spermatogonium, spermatocyte, spermatid, and spermatozoa.
