Estrogen, SERMS reduce asthma impact by halting constriction

For years, anecdotal evidence suggested that ovulating or pregnant women or post-menopausal women taking estrogen supplements, experienced fewer asthma attacks and less severe asthma symptoms, strongly suggesting that perhaps estrogen affects airway smooth muscle function by preventing the hyperresponsiveness characteristic of asthma and other chronic lung diseases.
