There is a relation between adipose tissue and macrophages. These macrophage cells influence adipose tissue by releasing many bioactive chemicals, including the wingless-type MMTV integration site family 5a (wnt5a) glycopeptides and the more traditional cytokines. Healthy adipocytes can release the wnt5a inhibitor Secreted frizzled-related protein 5(SFRP5). However, this protective effect was found to be reduced in obesity. This study aimed to assess the effect of follicular and serum levels of SFRP5 as well as serum and follicular levels of wnt5a on ICSI outcome and determine the potential roles of SFRP5 as a predictor of positive pregnancy in Iraqi infertile females undergoing ICSI with different body mass index .Ninety infertile females who received intracytoplasmic sperm injection and had various infertility factors between 18 and 45 years participated in this prospective clinical cross-sectional study. Follicular fluid, serum SFRP5, and serum and follicular fluid wnt5a levels were measured for all participants on the day of ovum pickup. In addition, ICSI outcomes were determined. There was a significant difference in the mean total gonadotrophin dose used among the three studied groups (p = 0.023), higher in overweight and obese females than normal-weight females. There was a positive significant correlation between serum plus follicular fluid wnt5a and total gonadotropin dose. Serum and follicular fluid SFRP5 levels were significantly higher in normal-weight females. There were higher serum (p-value=0.002) and follicular fluids (p-value=0.005) SFRP5 levels in pregnant females. Both SFRP5 and wnt5a glycoproteins were detected in infertile women's serum and follicular fluid. Serum and follicular fluid secreted frizzled-related protein 5 level positively associated with ICSI outcome. The cutoff values for serum and follicular fluid SFRP5 were ≥15.86 (ng/ml) and ≥ 11.3(ng/ml), respectively, as predictors of positive pregnancy in women undergoing IVF/ICSI cycles.
