Injected progestogen and lactation.
Norethisterone ethanate (200 mg every 84 days) and medroxyprogesterone acetate (150 mg every three months) were found to be completely effective in fertility control when started in the puerperium. Neither agent had any ill effect on the amount of milk or the duration of lactation. From the third month onward the three-hourly available milk and the infant weight gain per month were statistically higher in treated groups than in controls. Milk proteins showed a slight decrease in most groups, including the controls, owing to the low-protein diet.No important side effect was produced by these agents other than amenorrhoea.
