Percentage of in vivo fertilized eggs after natural mating with wild type (WT) or Ldhc^-/- (KO) males.

	A.			B.
genotype	Fertilized	2-cell embryos	4-cell embryos	Morula + blastocyst	Degenerated cells
WT (A.179/B.229)	62.77 % ±17.03	52.18 % ±23.65	46.93 % ±22.29	75.33 % ±12.38	24.67 % ±11.67
KO (A.263/ B.259)	0.30% ±0.81	3.41 % ±5.30	0 %	0 %	100 %
Control (195)	0 %	6.38 % ±6.08	0%

Eggs were collected: (A) the day following mating; fertilization was assessed by the presence of pronuclei and development to two-cell and four-cell embryos; (B) 4.5 days after mating; number of in vivo-derived blastocysts were counted. Results are expressed in percentage of fertilized, two-cell, four-cell embryos or blastocysts from total eggs collected. Controls are eggs from superovulated non-mated females, and represent spontaneous divisions. The total numbers of eggs analyzed for (A) and (B) are indicated in parentheses. At least 3 independent experiments were performed. Values are means ±SEM.
