| Horowitz et al []73 | 1980 | Fluid intake | 21 | Basal and post–suckling serum prolactin levels and the production rate of breast milk in groups with high (4 L/day) and low (800 ml/day) fluid intake were similar |
| Dearlove et al []74 | 1981 | Mild dehydration followed by sudden excessive hypotonic fluid intake (20 ml/kg body weight, mean sodium concentration <1 mmol/l) | A: 9 (to investigate changes in serum osmolality and prolactin levels)B: 7 (to investigate changes in milk yield) | A: No change in prolactin levels; serum osmolality was unaffected by fluid deprivation, while it was reduced by the following fluid load. B: No change in milk yield |
| Soto-Méndez et al []66 | 2016 | Maternal dehydration reflected by high urinary osmolality | 31, collections repeated in 15 | Milk osmolality is not significantly associated with urinary osmolality |
