Results shown as percentages for dichotomous variables and mean ± SEM for continuous variables. N = 60 embryos transferred (six per uterine horn) from five replicate experiments into 10 recipient mothers per HSA treatment (15 recipient mothers total). Different superscript letters denote significance between treatment groups within a row (P < 0.05). HSA human serum albumin
