TABLE 2.

Sex Ratio of Pre-Expanded and Expanding, As Well As Expanded and Hatched Blastocysts, on Day 8 of Culture With Glucose (0, 1.5, or 4 mM) and/or DNP (0, 10, or 100 μM)

Glucose (mM)	DNP (μM)	Pre-expanded and expanding blastocysts	Expanded and hatched blastocysts	Total (n)
0	0	0.60	0.42	0.52 (153)
	10	0.63z	0.59	0.61y (150)
	100	0.44	0.63	0.53 (95)
1.5	0	0.51	0.62z	0.55 (260)
	10	0.55	0.66y	0.59y (249)
	100	0.52	0.62z	0.55 (247)
4	0	0.58	0.63z	0.60# (94)
	10	0.67	0.74y	0.71y (51)
	100	0.67*	0.60	0.63z (70)

Number of cultures (n = 26). Deviation from the expected 0.50 ratio is denoted by superscripts:

^yP < 0.01

^zP < 0.05

^#P = 0.06; and

^*P = 0.07.
