Bone mineral: effects of oral contraceptives, pregnancy, and lactation
NF Goldsmith and JO Johnston
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.
