Abstract

The incidence of post-implantation pregnancy loss in 197 women was determined prospectively. The diagnosis of pregnancy was based on the detection of human chorionic gonadotropin in the urine during the luteal phase of each menstrual cycle. There were 152 conceptions in the 623 cycles studied with a pregnancy loss rate of 43%. 14 of the pregnancies ended in clinically recognised spontaneous abortions and in 50 the sole evidence of pregnancy was an increased concentration of urinary hCG. The maximum conception rate achieved was 36% in the first cycle after removal of an intra uterine device.

    In all three strategies, a 16% total live birth rate was used as the result of 6 months of attempting spontaneous pregnancy by a 40-year-old woman. This number was calculated by taking the likelihood of a pregnancy during 6 months of attempts (6) and subtracting the expected proportion of biochemical and clinical miscarriages (26). For ART success, a dataset containing all fresh, autologous ART cycle starts reported in 2011 was obtained from the SART Research Committee.

    Citation Excerpt :

    Even if all occurrences classified as fetal deaths were (correctly) observed, such a number would still be an underestimate of changes in fetal health, as it would fail to account for losses before 20 weeks. Given the majority of fetal losses/miscarriages occur within the first trimester (Miller et al., 1980), this would be ignoring a large portion of any effect. If we stratify our sample by estimated trimester of exposure, we find suggestive evidence effects are largest in magnitude for first trimester, further complicating direct observation using fetal death microdata (see Sanders and Stoecker, 2011).
