Hormonal flux: The primary hormone thought to influence tear production is testosterone. Estrogen and androgen may also play a role since the lacrimal gland possesses both estrogen and androgen receptors. Lactating women, who have elevated levels of the hormone prolactin, often show decreased tear production and increased dry eye.
