Insulin concentrations used in in vitro embryo production systems: a pilot study on insulin stability with an emphasis on concentrations measured in vivo

Table 2 Insulin concentration in maturation media measured immediately or after 22 h of incubation (INS0.1 = 0.1 µg/ml added insulin)

1709	Before maturation	0.24
	After maturation without oocytes added	0.19
	After maturation without oocytes added	0.16
2611	After maturation with co incubation of oocytes	0.13
2711	Before maturation	0.15
	After maturation without oocytes added	0.11
