Table 1 Prevalence of uterine niche in women with secondary infertility
Study | Design | n | Fertility status/ Prevalence of infertility |
|---|---|---|---|
Sonmezer 2022 [28] | Prospective cohort study | 16 | Among the 16 patients experiencing secondary infertility, excluding four with advanced maternal age as a causative factor, the remaining 12 patients were found to have Isthmocele as the sole identified factor. |
Etman 2022 [8] | Prospective cohort study | 50 | Out of the 50 women who experienced secondary infertility after at least one cesarean section, 31 of them, or 62%, were found to have uterine niches. |
Almarzuki 2022 [37] | Observational cross-sectional study | 100 | Out of 100 women who had both uterine niche and secondary infertility, 25 had experienced infertility for a minimum of 1 year, 31 for at least two years, and 44 for a minimum of 3 years. However, no correlation was observed between the anatomical characteristics of the uterine niche and this group’s secondary infertility duration. |
