OBJECTIVE: To investigate whether particular hormonal patterns could explain the persistence of cyclic menstruation-like bleeding during denied pregnancies.
METHODS: Hormone measurements were performed immediately after delivery in a total of 28 subjects with denied pregnancies. The results were studied in three patient subgroups: subjects with any cyclic bleeding during pregnancy (n = 22), subjects with cyclic bleeding during pregnancy until the delivery date (n = 7) and subjects with amenorrhea (n = 6). These data were compared with those of a control group (n = 126). In some of the women who reported cyclic bleeding, hormone assessments were also done once the lactation period ended.
RESULTS: For estradiol, free estriol and progesterone, no more than two values in each group were outside the 95% confidence interval of the control group. Several results for prolactin were remarkably lower. The findings for human chorionic gonadotropin, free testosterone, dehydroepiandrosterone sulfate, alpha-fetoprotein and thyroid-stimulating hormone were almost all within the 95% confidence interval. In seven subjects, abnormal results were obtained for the gondaotropin-releasing hormone/thyrotropin-releasing hormone test and the metoclopramid test after delivery and lactation. All of these subjects showed signs of corpus luteum insufficiency. In five subjects, evidence of hyperprolactinemia was found.
CONCLUSION: Results revealed that hormonal patterns assessed immediately after delivery do not provide any causal explanation for the cyclic menstruation-like bleeding that occurs during denied pregnancies. Hormone assessments performed after the lactation period, i.e. during a normal menstrual cycle, showed a number of abnormalities. However, a causal relationship could not be drawn.
