Aim
Epididymal proteins are known to play an important role in the maturation of spermatozoa. We ought to determine if there are regional differences in androgen-dependent epididymal proteins.
Methods
A group of adult rats was castrated and epididymides were removed three days following castration. The epididymides were dissected into caput, corpus and cauda segments, homogenized, and proteins were fractionated by anion exchange HPLC. Proteins in selected fractions were resolved by SDS-PAGE and visualized by silver staining.
Results
It was observed that the levels of multiple proteins drastically reduced in the various regions of epididymis of the orchiectomized rats.
Conclusion
The epididymal proteins appear to be useful markers to study androgenic action in the epididymis.
