Results were as follows;
@EN 1. The seminal parameters, SMI value and sperm penetration distance in both fertile & infertile groups showed significant statistical differences(p<0.01).
2. The SMI rages of the fertile & infertile groups were compared poor(6.7% of fertiles : 28.9% of infertiles), medium(20% : 39.3%), good(73.3% : 31.9%), and the differences were significant difference(p<0.01).
3. Im the general sample. Semen with normal SPA(≥30 mm) presented higher total sperm count, motility, viability and total functional sperm fraction than abnormal SPA(<30 mm) (p<0.01).
4. The sperm parameters among the three categories of the SMI ranges were significantly different(p<0.001).
5. In the normal SPA group(n=124), SMI value showed 6 poor(4.8%), 42 medium(33.9%), 76 good(61.3%) respectively. In the abnormal SPA group(n=56), SMI value showed 36 poor(64.3%), 20 medium(35.7%), 0 good(0%) respectively.
6. Positive correlation was observed among the conventional sperm parameters, SPA and SMI values.
Considering all above results, the SMI provides the positive correlation of the sperm penetration distance for sperm count, motility, viability, and total functional sperm fraction(TFSF). This suggest that the SMI has the potential to replace the
SPA(sperm mucuc penetration assay ; Penetrak), as the simplest and most precise method of evaluating sperm function.
