Diagnosis
Ventriculitis is commonly diagnosed using a variety of tests or procedures. When a physician suspects that a patient has ventriculitis, the first step is typically to ascertain the presence of the inflammation using computed tomography (CT) or magnetic resonance imaging (MRI) technology to "take a picture" of the brain. The scans allow physicians to check for "intraventricular debris and pus, abnormal periventricular and subependymal signal intensity, and enhancement of the ventricular lining," all of which indicate the likelihood of ventriculitis. MRIs have been reported as being highly effective and sensitive in detecting such indicators, even from an early stage. After determining whether a patient shows signs of ventriculitis, the doctor may choose to pursue a more specific and useful diagnosis to find the cause of the ventriculitis. This is done by obtaining a sample of cerebrospinal fluid, most commonly via a procedure called a lumbar puncture or spinal tap. For patients with an implanted external ventricular drain, cerebrospinal fluid can be collected from the drains output. After the sample of fluid is obtained, a battery of tests featuring gram staining will be performed to identify any offending pathogen or infection agent. The test will also determine any resistance the pathogen may have to antibiotics. By identifying the viral or bacterial cause of the ventriculitis, doctors are more able to effectively treat the inflammation and infection.
Anejaculation is the pathological inability to ejaculate despite an erection in males, with (orgasmic) or without (anorgasmic) orgasm. Causes
It can depend on one or more of several causes, including:

Sexual inhibition
Pharmacological inhibition. They include mostly antidepressant and antipsychotic medication, and the patients experiencing that tend to quit them
Autonomic nervous system malfunction
Prostatectomy - surgical removal of the prostate. Ejaculatory duct obstruction
Spinal cord injury causes sexual dysfunction including anejaculation. The rate of being able to ejaculate varies with the type of lesion, as detailed in the table at right. Old age
Diabetes mellitusAnejaculation, especially the orgasmic variant, is usually indistinguishable from retrograde ejaculation. However, a negative urinalysis measuring no abnormal presence of spermatozoa in the urine will eliminate a retrograde ejaculation diagnosis. Thus, if the affected person has the sensations and involuntary muscle-contractions of an orgasm but no or very low-volume semen, ejaculatory duct obstruction is another possible underlying pathology of anejaculation. Management
Anejaculation in spinal cord injury

The first-line method for sperm retrieval in men with spinal cord injury is penile vibratory stimulation (PVS). The penile vibratory stimulator is a plier-like device that is placed around the glans penis to stimulate it by vibration. In case of failure with PVS, spermatozoa are sometimes collected by electroejaculation, or surgically by per cutaneous epididymal sperm aspiration (PESA) or testicular sperm extraction (TESE). == Notes ==
