Does nicotine lower estrogen levels?

ABSTRACT. Nicotine addiction produces diverse physiological effects common to both men and women because of activation of the nicotinic acetylcholine receptors. In addition to these effects, nicotine reduces circulating estrogen (the female sex hormone) levels and leads to early onset of menopause in women.

Does nicotine block estrogen?

Smoking-attributed nicotine is known to inhibit aromatase enzyme activity, which catalyzes the conversion of androgens into estrogens [10]. Consequently, nicotine reduces circulating estrogen levels and leads to early onset of menopause in women [11,12,13,14,15,16,17,18,19].

Does smoking lower estrogen?
