Hormone changes occurring during second trimester abortion induced with 15 (S)-15-methyl prostaglandin F2alpha.
Changes in progesterone, human placental lactogen (HPL), cortisol and estradiol-17B were measured during second trimester abortion induced by I.M. 15-methyl PGF2alpha. A rapid decline in progesterone and HPL was found, indicating perhaps an initial effect on the placenta. A rapid rise in cortisol was found, but it is not clear if this is due to stress or part of the termination mechanism. The changes of estradiol were not as distinct and may reflect opposite effects of the prostaglandin on the placenta and adrenals. Similar hormonal changes were observed regardless of the duration of gestation.
