2 (N = 10)	93.7±10.1	88.1	924.6±52.2	886.4
3 (N = 10)	82.6±9.3	76.4	930.7±36.7	754.7
4 (N = 6)	124.8±11.7	129.5	882.4±105.5	903.8
5 (N = 10)	100.7±15.3	88.1	947.8±70.8	842.3
6 (N = 11)	87.4 ± 6.8	90.0	876.7 ± 61.7	813.3
7 (N = 10)	111.1 ± 17.6	90.0	743.33 ± 49.2	770.0

Values are given as means ± SD. Average placental and fetal weights do not include the Lhx3−/−;Lhx4−/− weights.
