Urinary estrogen excretion and concentration of serum human placental lactogen in pregnancies following legally induced abortion.
Feto-placental function was assessed by 24-hour excretion of estrogen in urine and by the concentration of human Placental Lactogen (hPL) in serum in pregnant women whose previous pregnancy was terminated by legally induced abortion. The mean 24-hour excretion of estrogens in urine and the mean concentration of hPL in serum were no lower in this group than in women without previous induced abortion. Neither was the frequency of a low 24-hour excretion of estrogens in urine or low concentration of hPL in serum (values less than mean - 1.96 s) found to be increased. This study could not demonstrate an increased frequency of dysfunction of the feto-placental unit during the last part of pregnancy in women with previous legally induced abortion. These findings indicate that legal abortion does not seem to increase the frequency of retarded intrauterine growth in a subsequent pregnancy.
