In our study, no difference in miscarriage rate was noted between lesbians and heterosexual women.
There was no statistically significant difference in miscarriage rate between T1 and T2 women.
However, there was no significant difference in miscarriage rate between Group A and Group B (3.1% vs. 11.8%, respectively, p = 0.273).
However, there was no significant difference in miscarriage rate between the time-lapse system and the conventional incubator (3.1% vs. 11.8%, respectively, p = 0.273).
31 34 Thus the absolute risk of miscarriage associated with bivalent HPV vaccination in weeks 13-20 after gestation is small (in our study, the absolute difference in miscarriage rates was 0.9% (that is, 3.5% minus 2.6%), table 1).
The authors suggest that the difference in miscarriage rates between the two groups may be due to the heterosexual single women in their study being older and having failed to conceive for some time prior to clinic referral.
Two pooled analyses by the vaccine manufacturer did not find a difference in miscarriage risk for pregnancies conceived in a risk window of −30 to 45 days from bivalent HPV vaccination.
A study in China on the effect of HPV on the pregnancy outcome of IVF treated patients found no difference in miscarriage rates between women with abnormal cervical cytology who had a positive high risk HPV test (n = 56) and those who tested negative for high-risk HPV (n = 56, Yang et al., 2013).
For vaginal misoprostol, doses of 600 ug and 800 ug have no significant differences in producing miscarriage within about 24 hours (RR 0.82, 95% CI 0.63 to 1.07).
There is no evidence for differences in the miscarriage rates after the hysteroscopic removal of not more than two submucous fibroids or one submucous fibroid with one intramural fibroid in women with otherwise unexplained infertility for at least 1 year, compared to regular fertility-oriented intercourse (OR 1.5, 95 % CI 0.47 5.00).
