Welcome to Spermac Stain, a revolutionary andrology staining medium.

Spermac is a cell-staining medium for use predominantly on sperm. Using a novel dual-staining mechanism that is unique in its action, it provides the best visualisation of spermatozoa available anywhere in the world.

Spermac offers considerably improved visualization of morphology of spermatozoa, staining the nucleus and cytoplasm differentially, which allows for direct visualization of morphological defects, previously indistinct with traditional staining methods. Spermac also offers improved visualisation of the acrosome, the integrity of which has been shown to correlate with IVF success when using frozen semen
