Description
Summary:The relationship between spermicide use and spontaneous abortion was ex amined in a New York City case-control study carried out during 1974–1982. in a series of matched sample analyses, case groups categorized by karyotype of the abortus were compared to a control group of prenatal patients with respect to spermicide use. Spermicide use was defined in terms of proximity to the date of conception of the study pregnancy and duration of the episode of use most recent to the study pregnancy. There was no association between spermicide use defined either in terms of recency or duration of use and chromosomally normal abortions, which comprise about 60% of all spontaneous abortions. Similarly, there was no association between spermicide use and the various types of chromosomally abnormal abortions, with the exception of trisomic abortion. Spermicide use for more than one year at any time prior to conception was more common in the cases aborting trisomic conceptions than in the control group (odds ratio = 1.9, confidence limits = 1.2, 3.0). There was evidence to suggest that the association varied with maternal age and phase of entrance into the study.
