BACKGROUND: There is evidence that the nasal mucosa is affected by estrogen influence.
Some authors have already detected estrogen receptors (ER) in the nasal mucosa.
However, there doesn't seem to be a consensus about the concentration and distribution of
the ER or the possible influence of hormonal contraceptives in the nasal mucosa.
OBJECTIVE: The study was conducted to evaluate the influence of oral contraceptives on
the distribution and concentration of estrogenic receptors in nasal mucosa. STUDY DESIGN …
