The use of hormonal preparations for the control of postpartum breast symptoms is advisable. In this study of 118 maternity patients, a new androgen-estrogen combination tablet was administered to 75, while 43 received placebo tablets. The androgen-estrogen combination, given at three dosage levels, was effective without significant side-effects. Those patients who received the highest dosage experienced the most marked relief of breast pain, engorgement, and lactation and showed the least need of additional supportive measures.
