Spermac stain was developed in 1983 as an alternative to traditional papiniculau staining methods for andrology research, development and fertility work.

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.

Spermac stains spermatozoa of all mammalian species, many non-mammals and even some invertebrates.

Spermac offers a cost-comparable alternative to traditional staining methods and is currently providing the best visualization of spermatozoa morphology worldwide.
