theca interna
Theca interna cells express receptors for luteinizing hormone, which when activated will stimulate the production of androstenedione from cholesterol by the enzyme desmolase. Androstenedione ultimately gives the granulosa cells the precursor substrate for estrogen manufacturing. [ http://en.wikipedia.org/wiki/Theca_externa#Theca_interna ]
