Abstract
Estimating bone mineral by the photon absorption (125I) method applied to the distal part of the radius, it was found that young women using oral contraceptives containing a daily dose of 100 micrograms of mestranol had higher concentrations of bone mineral than non-users. Women twenty to fifty-nine years old who had lactated were among the poorly mineralized, while those who had lactated but were now using oral contraceptives in various combinations were among the highly mineralized.
