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.

First, primitive germ cells known as spermatogonia divide to produce offspring cells, or spermatocytes, that ultimately redivide twice to form young sperm cells known as spermatids.eprinted with Permission by DrRajMD.
