Leydig cells
These cells contain the LH-R, lie outside the seminiferous tubule, and produce testosterone
Sertoli cells
These cells contain the FSH-R, lie within the seminiferous tubule, and produce a number of products (ex. MIF, ABP, inhibin)
Androgen binding protein
This product of the sertoli cells sequesters large concentrations of testosterone within the seminiferous tubule
inhibin
This product of the Sertoli cells inhibits production of FSH in the pituitary
GnRH
This hypothalamic hormone stimulates the production of FSH and LH
testosterone
This testicular product negatively feeds back to inhibit LH and GnRH production
17-beta-HSD
This enzyme converts both DHEA and androstenedione into testosterone
5-alpha reductase
This enzyme peripherally converts testosterone to dihydrotestosterone
estradiol
The action of aromatases converts testosterone to this
Sex Hormone Binding Globulin
Most serum testosterone is bound to this protein
albumin
Most serum estradiol is bound to this protein
finasteride
This 5-alpha reductase antagonist is used in the medical treatment of prostate cancer
