What Does Decrease In Acrosome Positive Reaction Indicates The Possibility Of Low Fertilization Mean?

Total Ejaculate Millions     203 million Total Ejaculate: Normal (5th per: 40 75th per: 120) Sperm Conc. (millions / ml)       58 mill/ml                 MOTILITY ASSESSMENT (5th percentile value) Sperm Motility     1 Hr     2 Hrs Total Progressive      30%     10% Non Progressive       05%     02% Immotile       65%      88%            Total motility (Total Progressive + Non Progressive)     35%     12% 1 Hour Total motility: Sub Normal (5th Per: 42 75th Per: 50) Advanced CASA parameters     Micro mt/sec Straight Line Velocity-VSL      Not assessed Curvilinear Velocity –VCL      Not assessed Hyper activation –H max assay      Not assessed Advanced Total Progressive Motility Assessment (CASMA) Rapid Progressive      02% Slow Progressive      28% Advanced Total progressive motility: Sub Normal (5th Per: 10      75th Per: 15) MORPHOLOGY ASSESSMENT (TYGERBERG KRUGER) (5th percentile value) Morphology      % Normal Forms     04% Over all Defects      96% Sperm Morphology: Normal (5th Per: 4 75th Per: 9) Head Defects     59% Mid Piece and Neck Defects     20% Tail Defects     04% Multiple Defects     13% Excessive residual cytoplasm (ERC)     09% Ex. residual cytoplasm: Not Significant ADDITIONAL PARAMETER ASSESSMENT: Round cells: 02/hpf Bacteria: Not Significant       RBC: Nil           Agglutination: Nil Cellular debris: Not Significant Comments if any: SPERM FUNCTIONAL INTEGRITY ASSESMENT – SFI Flagellar Integrity - Hypo Osmotic Swelling                  53% Osmotic Swelling Test Normal                : 55 % spermatozoa with tail coiling Significance : This test is a good index of healthy spermatozoa. Clinical Relevance : Decrease in HOS positive reaction indicates loss of viability                     Hence may be an indication of degenerative changes occurring Spermiation defects - Acrosome Reaction after Ionophore Challenge 12% ARIC Test Normal : 15 % spermatozoa with halos having mean diameter of 10 µm Subnormal : 10-15 % spermatozoa with mhalos having mean diameter of 10 µm Abnormal           : Significance: This test evaluates the functional status of sperm acrosome and is a good indicator of sperm’s ability to penetrate the oocyte. Clinical Relevance: Decrease in Acrosome positive reaction indicates the Possibility of low or nil fertilization Can you please help understand the report
