Abstract
Serum hormone levels in women undergoing successful first and second trimester abortions induced by 9-deoxo-16, 16-dimethyl-9-methylene prostaglandin E2 vagitories have been measured. Significantly decreased levels of prolactin (p<0.01) and TSH (p<0.05) were seen in both groups of women but the drop appeared sooner, within two hours, in first trimester abortions. Regardless of gestational length there was a significant decrease in serum human chorionic gonadotropin (hCG) (p<0.01) concentrations in maternal serum six hours into treatment. In the second trimester abortions total estriol, α-fetoprotein and lactoplacental hormone hPL were analysed in maternal serum but the levels did not change over the eight hour investigation period. It is speculated that the PGE2-derivative most likely affects the maternal pituitary secretion of prolactin and TSH, possibly via direct or indirect interference with TRH mechanism(s).
