Understanding Semen Analysis Results: Key Infertility Insights
A semen analysis is crucial for couples struggling with infertility, with abnormal results affecting about 40% of infertility cases. Key factors include sperm count, motility, and morphology, as defined by the World Health Organization. Treatments like IVF can help even with low sperm quality.
Key Takeaways
Semen Analysis Criteria for Fertility Evaluation
The World Health Organization defines normal semen analysis as a minimum sperm count of 20 million/ml, 50% motility, and 30% normal morphology. Strict criteria like Kruger’s require at least 14% normal-shaped sperm to assess fertility potential accurately.
Common Causes of Abnormal Semen Analysis Results
Abnormal results may stem from varicocele, hormonal imbalances, genetic issues, or antisperm antibodies. Repeating the test after 2-4 weeks is recommended due to variability, and further tests like ultrasound or hormonal assessments can identify underlying issues.
Treatment Options for Male Infertility with Low Sperm Quality
Advances like IVF and intrauterine insemination (IUI) offer solutions even with low sperm count. IVF success rates exceed 50-60% per attempt, while surgical corrections for anatomical issues like varicocele can improve sperm function.
