Ovarian Theca Cells

Meaning

Ovarian theca cells are specialized endocrine cells that form a layer surrounding the developing ovarian follicle, working synergistically with granulosa cells to facilitate steroidogenesis and oocyte maturation. These cells are the primary source of androgen precursors, specifically androstenedione, which are essential for subsequent conversion into estradiol by the granulosa cells. Their proper function is critical for maintaining a healthy menstrual cycle and overall reproductive endocrine health.
