Abstract

Purpose: To consider the relationship between different sperm nuclear maturity tests and in vitro fertilization (IVF) rate, in order to select the most sensitive, specific, and independent factor(s) for prediction of in vitro fertilization. Methods: Infertile couples (101) were randomly selected from IVF candidates referred to Isfahan Fertility and Infertility center. Semen samples were collected on the day of oocyte recovery. Following routine semen analysis, major portion of the semen was prepared for routine IVF insemination and the remaining was used for following sperm nuclear maturity tests: chromomycin A3 (CMA3), aniline blue, sodium dodecyl sulphate (SDS) test, and acridine orange test with or without heat shock (87°C, 5 min). Sperms (200) were evaluated for each test. The results were recorded and analyzed for their correlation to fertilization rate, using correlation coefficient, logistic regression analysis, student t-test, and receiver operating characteristics (ROC) curve. Results: Among these tests, aniline blue and CMA3, and semen parameters, sperm morphology, and sperm motility showed a significant correlation with fertilization rate. Using logistic regression analysis, sperm morphology and CMA3 were the only independent factors related to in vitro fertilization. ROC curves showed that among above tests, CMA3 is the most specific and sensitive for sperm nuclear maturity. Conclusion: Among CMA3, aniline blue, SDS test, and acridine orange, CMA3 was the most sensitive and specific test that can be used along with routine semen analysis for more precise prediction of fertilization rate.
