What is produced in follicles?

Follicles are specialized structures in various organs, primarily in the ovaries and thyroid gland. In the ovaries, follicles produce eggs (oocytes) and secrete hormones such as estrogen and progesterone, which are crucial for regulating the menstrual cycle and supporting pregnancy. In the thyroid gland, follicles produce thyroid hormones (thyroxine and triiodothyronine) that regulate metabolism and energy levels in the body.
