Abstract

The effects of insulin, glucagon, β‐hydroxybutyrate, and acetoacetate on the in vitro development of preimplantation mouse embryos were studied. In controls, 24% of blastocysts failed to develop successfully when grown for 72 h in Eagle's medium supplemented with 10% fetal calf serum. Insulin at concentrations of 1.0 and 2.0 IU/ml of culture medium interfered with development in 62–63% of the blastocysts. Preimplantation embryos showed a threshold pattern in their reaction to glucagon: its addition in concentrations of 0.0015 mM (5 μg/ml) did not significantly inhibit blastocyst development, while concentrations of 0.003 mM (10 μg/ml) inhibited 70% of blastocysts. The embryotoxic effects of ketone bodies were manifested only in relatively high doses. β‐hydroxybutyrate was embryotoxic at concentrations greater than 5 mg/ml, and its effects were dose dependent: 48 mM (6 mg/ml) inhibited 45% of blastocysts, while 80 mM (10 mg/ml) arrested 87% of embryos from further development. Acetoacetate at concentrations of 0.1 mM (10 μg/ml) inhibited the development of 50% of the blastocysts, and its effects were not dose dependent: concentrations of 1 mM (100 μg/ml) inhibited development in 63% of the embryos. The combination of the diabetic metabolic factors in relatively low concentrations was highly embryotoxic, especially when accompanied by hyperglycemia.
