This study evaluated whether follicular fluid levels of BMP2, BMP4, BMP7, GDF9, and Emmprin (basigin) were associated with clinical pregnancy after ICSI in 77 patients, measuring these factors during oocyte retrieval and comparing levels between those who did or did not achieve clinical pregnancy. The authors found that follicular BMP4 levels were significantly higher and Emmprin levels were significantly lower in patients who achieved clinical pregnancy, while BMP2, BMP7, and GDF9 levels did not differ between groups. The paper’s main caveat is that the analysis is limited to associations with clinical pregnancy and does not establish mechanistic causality for these biomarkers. The paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Abstract

PurposeTo evaluate the relationship of clinical pregnancy rates with bone morphogenetic proteins 2-4-7 (BMP 2, 4, 7), growth differentiation factor 9 (GDF 9), and Emmprin levels in follicular fluid of intracytoplasmic sperm injection patients.MethodsFollicular fluid of 77 patients who underwent ICSI procedure was collected during the oocyte retrieval procedure. And follicular fluid levels of BMP 2, BMP 4, BMP 7, GDF 9, and Emmprin (Basigin) were measured and compared for clinical pregnancy rates.ResultsFollicular levels of BMP 4 was significantly higher whereas Emmprin levels were lower in patients who had achieved clinically diagnosed pregnancy compared with those who did not achieve clinical pregnancy after ICSI procedure (P = 0.007 and P = 0.035, respectively). BMP 2, BMP 7, and GDF 9 levels were comparable for both groups.ConclusionClinical pregnancy rates after ICSI may be associated with follicular fluid levels of Emmprin and BMP 4. Follicular levels of Emmprin and BMP 4 can be used as a marker (as markers for predicting ICSI outcomes) for a better ICSI outcome.

Abstract

Purpose To evaluate the relationship of clinical pregnancy rates with bone morphogenetic proteins 2-4-7 (BMP 2, 4, 7), growth differentiation factor 9 (GDF 9), and Emmprin levels in follicular fluid of intracytoplasmic sperm injection patients.

Methods

Follicular fluid of 77 patients who underwent ICSI procedure was collected during the oocyte retrieval procedure. And follicular fluid levels of BMP 2, BMP 4, BMP 7, GDF 9, and Emmprin (Basigin) were measured and compared for clinical pregnancy rates.

Results

Follicular levels of BMP 4 was significantly higher whereas Emmprin levels were lower in patients who had achieved clinically diagnosed pregnancy compared with those who did not achieve clinical pregnancy after ICSI procedure (P = 0.007 and P = 0.035, respectively). BMP 2, BMP 7, and GDF 9 levels were comparable for both groups.

Conclusion

Clinical pregnancy rates after ICSI may be associated with follicular fluid levels of Emmprin and BMP 4. Follicular levels of Emmprin and BMP 4 can be used as a marker (as markers for predicting ICSI outcomes) for a better ICSI outcome. Similar content being viewed by others
