1 You may neglect height and width of lenses but make sure to find a frame with the accurate total width as required. 2  The other measurements (Nose bridge & Temple size) should also be close to your requirements.3  Frame measurements are listed in mm (millimeters). 4  If you are using an inch ruler, 1 inch = 25.4 mm.

Testosterone stimulates the final steps of spermatogenesis in the seminiferous tubules. 7. Once the degree of spermatogenesis required for male reproductive functions has been achieved, Sertoli cells release inhibin, a protein hormone named for its role in inhibiting FSH secretion by the anterior pituitary.
From Wikipedia, the free encyclopedia. Spermatogenesis is the process in which spermatozoa are produced from male primordial germ cells by way of mitosis and meiosis. The initial cells in this pathway are called spermatogonia, which yield primary spermatocytes by mitosis.hus, the primary spermatocyte gives rise to two cells, the secondary spermatocytes, and the two secondary spermatocytes by their subdivision produce four spermatozoa. Spermatozoa are the mature male gametes in many sexually reproducing organisms.
