Our previous studies have demonstrated that rat epididymis expressed luteinizing hormone receptor (LHR), tissue type ( t ) and urokinase type ( u ) PA, mRNAs, and tPA activity was stimulated in vitro by human chorionic gonoadotrophin ( HCG ) ... In-vitro experiments showed that both tPA and uPA activities in epididymal cells were dramatically stimulated by HCG , but not by follicle stimulating hormone ( FSH )

PRL also suppressed HCG induced tPA gene expression in a dose- and time dependent manner
