Estimation of interhemal membrane thickness of the male and female labyrinth. Semi-thin sections stained with toluidine blue of the placental labyrinth at a E15 and b E20. Electron micrographs of the labyrinth at c E15 and d E20. White scale bars in D and E are 10 um. Interhaemal membrane thicknesses at e E15 and f E20. Data shows mean ± SEM, analysed by Student’s t test. White (male) and black (female). Data averaged 6 individual membranes from 2 blocks. E15 N = 5/sex from 3–4 litters. E20 N = 4/sex from 4 litters
