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.
Hydralazine, sold under the brand name Apresoline among others, is a medication used to treat high blood pressure and heart failure. This includes high blood pressure in pregnancy and very high blood pressure resulting in symptoms. It has been found to be particularly useful in heart failure, together with isosorbide dinitrate, for treatment of people of African descent. It is given by mouth or by injection into a vein. Effects usually begin around 15 minutes and last up to six hours.Common side effects include headache and fast heart rate. It is not recommended in people with coronary artery disease or in those with rheumatic heart disease that affects the mitral valve. In those with kidney disease a low dose is recommended. Hydralazine is in the vasodilator family of medications, so it is believed to work by causing the dilation of blood vessels.Hydralazine was discovered while scientists at Ciba were looking for a treatment for malaria. It was patented in 1949. It is on the World Health Organizations List of Essential Medicines. In 2019, it was the 99th most commonly prescribed medication in the United States, with more than 6 million prescriptions. Hydralazine has an adverse drug event of inducing drug-induced lupus and this drugs use is declining with more prescribers prescribing calcium channel blockers. Medical use
Hydralazine is not used as a primary drug for treating hypertension because it elicits a reflex sympathetic stimulation of the heart (the baroreceptor reflex).
