According to the medical standard, it seems that your sperm test results are not normal:
1. Sperm volume should be 2.0-6.5 ml; yours is 1.5ml and is referred to as "hypospermia";
2. The time required for liquefaction should be up to 30 min; your measures at 50 min;
3. pH value should be 7.2-7.8; yours is 8.5 which indicates bacterial infection. The presence of bacteria and increased white cell count (WCC) in the sperm also confirms bacterial infection. The presence of erythrocytes and white blood cells with predomination of lymphocytes over neutrophils could indicate tuberculosis of the testicles;
4. Spermatozoid concentration should be >20 millions/ml; yours is 6.5 million/ml and is referred to as "oligozoospermia";
5. Total sperm mobility should be greater than 50% and 4 hours after ejaculation less than 30% of the spermatozoids should lost their mobility; your values have not been reported
6. Vitality of the spermatozoids: >50% of the spermatozoids should be alive; again, there is no data about the vitality of your spermatozoids;
7. Spermatozoid morphology: >50% of the spermatozoids should have normal morphology and in your case there are only 30% with normal morphology (teratozoospermia).
Abnormalities of the sperm are probably the reason for your sterility but it is very hard to say what caused those abnormalities. Enlarged veins of the testicles, or "varicocela", can cause sperm abnormalities... but in your case there are also evidences for persistence of some testicular infection. A specific infection (such as tuberculosis) must first be excluded before proceeding. After establishing a proper diagnosis and treating the infection you can evaluate your fertilization ability. You can consult a urologist for an expert opinion.
