Summary
Objective sperm analysis using nine nonconventional parameters can predict in vitro fertilization (IVF) success. This aids in selecting the best assisted reproduction technique, like IVF or intracytoplasmic sperm injection (ICSI), for infertile couples.
Area of Science:
- Reproductive Medicine
- Andrology
- Embryology
Background:
- Basic semen parameters have limited predictive power for male fertility.
- Assisted reproductive technologies (ART) require accurate patient stratification.
Purpose of the Study:
- To evaluate if objective sperm analyses beyond basic parameters can predict male fertility.
- To determine if novel sperm parameters can guide the selection of optimal ART techniques.
Main Methods:
- Analysis of 21 objective semen parameters in 78 infertile couples with prior insemination failures.
- Semen analysis performed on fresh samples and post-sperm selection.
- Couples underwent in vitro fertilization (IVF) and were classified as fertile or infertile based on embryo development.
Main Results:
- Multiple variant discriminant factorial analysis identified nine key nonconventional sperm parameters.
- These nine parameters defined two distinct semen classes with 74.4% accuracy in predicting fertile vs. infertile groups.
- The identified parameters showed significant correlation with IVF outcomes.
Conclusions:
- Novel objective sperm parameters can predict the likelihood of obtaining embryos during IVF.
- These parameters facilitate personalized selection between IVF and intracytoplasmic sperm injection (ICSI).
- This approach enhances the efficiency and success rates of assisted reproduction.
