Comparison of the fertilization rate (FR) in infertile patients who have (a) high (10≤) and (b) low (<10) SI₅₀ titers in their follicular fluid (FF). In total, 52 of the 65 mature oocytes inseminated were fertilized and the FR was 80.0%. (a) In the four IVF treatment cycles with high (10≤) SI₅₀ titers in FF, 36 mature oocytes were inseminated and 28 fertilized, giving a FR of 77.8%. (b) In the seven treatment cycles with low (<10) SI₅₀ titers in FF, 29 mature oocytes were inseminated and 24 fertilized, giving a FR of 82.8%. There was no difference in FR between the two groups (P = 0.62).
