Serum progesterone concentrations in Galago crassicaudatus were quantified at 3‐week intervals throughout the 136‐day pregnancy. Progesterone concentrations were significantly elevated over those of nonpregnant controls as early as 6 weeks after conception. Progesterone continued to increase throughout gestation. The progesterone profile in pregnant G. crassicaudatus quantitatively resembles that of chimpanzees and qualitatively resembles that of humans. In two animals that aborted, progesterone concentrations after abortion decreased to values comparable to those seen in nonpregnant animals.
