Gene expression of endothelin-1, endothelin-converting enzyme-1, and endothelin receptors in human epididymis.


We have previously reported the presence of endothelin-1 (ET-1) and its receptors in the human testis. In the present study we extended our investigations to human epididymis. The rationale of our study originated from the fact that sperm appear to be immotile during their transit through the epididymis. Hence, it is conceivable that specific factors… (More)
