Oral sex is associated with reduced incidence of recurrent miscarriage[$]
In a matched case control study, 97 women with at least three unexplained consecutive miscarriages prior to the 20th week of gestation with the same partner were included. Cases were younger than 36 years at time of the third miscarriage. The control group included 137 matched women with an uneventful pregnancy. The association between oral sex and recurrent miscarriage was assessed with conditional logistic regression, odds ratios (ORs) were estimated. Missing data were imputed using Imputation by Chained Equations.
In the matched analysis, 41 out of 72 women with recurrent miscarriage had have oral sex, whereas 70 out of 96 matched controls answered positive to this question (56.9% vs. 72.9%, OR 0.50 95%CI 0.25-0.97, pā=ā0.04). After imputation of missing exposure data (51.7%), the association became weaker (OR 0.67, 95%CI 0.36-1.24, pā=ā0.21).

Actually, there's lots of reasons to be dubious about the study, e.g. the sample size is quite small. But it could be a good pointer for future more robust studies. Getting a good study is going to be difficult, though, as we don't even have a good estimate as to the frequency of miscarriages. And one may even wonder about the definition. E.g., does it count in the first month? The sixth week?
