Maintaining optimal frequency of coital activity: sperm counts can be depressed by daily coital activity and sperm motility may be depressed by coital activity that takes place too infrequently (abstinence 10–14 days or more). Wearing a protective cup and jockstrap to protect the testicles, in any sport such as baseball, football, cricket, lacrosse, hockey, softball, paintball, rodeo, motorcross, wrestling, soccer, karate or other martial arts or any sport where a ball, foot, arm, knee or bat can come into contact with the groin. Diet: Healthy diets (i.e. the Mediterranean diet) rich in such nutrients as omega-3 fatty acids, some antioxidants and vitamins, and low in saturated fatty acids (SFAs) and trans-fatty acids (TFAs) are inversely associated with low semen quality parameters. In terms of food groups, fish, shellfish and seafood, poultry, cereals, vegetables and fruits, and low-fat dairy products have been positively related to sperm quality. However, diets rich in processed meat, soy foods, potatoes, full-fat dairy products, coffee, alcohol and sugar-sweetened beverages and sweets have been inversely associated with the quality of semen in some studies. The few studies relating male nutrient or food intake and fecundability also suggest that diets rich in red meat, processed meat, tea and caffeine are associated with a lower rate of fecundability. This association is only controversial in the case of alcohol. The potential biological mechanisms linking diet with sperm function and fertility are largely unknown and require further study. Treatment
Treatments vary according to the underlying disease and the degree of the impairment of the males fertility.
Special obtaining
Psychological inhibition– Psychotherapy
– Intercourses with special preservatives without lubricants or spermicides. In case of religion limitations we should use a SCD, or Seminal Collection Device, such as preservatives with holes. – Drug stimulation
– Percutaneous spermatozoa obtaining directly from epididymis, testes, etc. Neurological injury– Vibro-stimulation
– Electro-stimulation

Retrograde ejaculationThis type of ejaculation happens when there is a defect on prostate, so the sample is not ejaculated outside but to the bladder. So, in that case, what we have to do to obtain the sample is:
– Intake bicarbonate, about 25 grams, the night before and the morning of the sample obtaining. This will neutralize acidic urine and will turn it alkaline, near semens pH, so spermatozoa can survive. – Before masturbation we have to urinate to empty the bladder. This must go to the first recipient. – Just after that, the subject has to masturbate and ejaculate, obtaining then a new urine sample with ejaculation that will be stored on the second recipient. – Finally we have to obtain the next urine, 2nd urine, for potential ejaculation fraction, which will be stored in the third recipient. This may contain the most important fraction. Blood sample
Common hormonal test include determination of FSH and testosterone levels. A blood sample can reveal genetic causes of infertility, e.g. Klinefelter syndrome, a Y chromosome microdeletion, or cystic fibrosis. Ultrasonography
Scrotal ultrasonography is useful when there is a suspicion of some particular diseases. It may detect signs of testicular dysgenesis, which is often related to an impaired spermatogenesis and to a higher risk of testicular cancer.
