| where are leydig cells and what do they make? | interstitial space; testosterone |
| germinal epithelium generally has about how many layers? | 4-8 |

| what stimulates leydig cells to secrete testosterone? | lh |
| order of sperm from seminiferous tubule to outside world? | seminiferous tubule->rete testis->efferent ductules->epididymis->ductus deferens->urethra |
| rete testis is what epithelium? | simple cuboidal (duct) |
| function of efferent ductules? | resorbs fluid from semen |
| efferent ductules epithelium? interesting morphology? | cuboidal/ciliated columnar; has circular layer of smooth muscle |
| what is the epithelium of the epididymis? | pseudostratified columnar epithelium with stereocilia |
| what is epithelium of ductus deferens? interesting morphology? | pseudostratified columnar epithelium; 3 layers of muscle |
