Role of granulocyte elastase and interleukin-6 in the diagnosis of male genital tract inflammation.

Chronic genital tract inflammations are a frequent cause or at least a concomitant factor of male fertility disturbances. The diagnosis is difficult because of the mostly asymptomatic course of the disease. Therefore, determination of biochemical markers of inflammation in addition to the number of leucocytes in the seminal plasma has been recommended. The aim of the study was to find out whether determination of granulocyte elastase and interleukin-6 provide comparable and reliable results with regard to diagnosis of genital tract inflammation; in addition, the association between genital tract inflammation and semen quality should be evaluated with special focus on potentially disturbed sperm functions like sperm motility and DNA integrity. In a prospective study, the concentrations of interleukin-6 (IL-6) and granulocyte elastase were determined in seminal plasma samples from 340 patients to investigate the relationship with other parameters of genital tract inflammation such as the number of peroxidase-positive cells and conventional semen parameters. Microbiological investigations were included. As post-testicular inflammatory influences may cause sperm DNA damage, the correlation between IL-6 and elastase and DNA integrity was evaluated by the sperm chromatin structure assay. IL-6 and elastase were significantly correlated both with each other (P < 0.01) and the number of peroxidase-positive cells (P < 0.01). IL-6 showed a highly significant negative correlation with sperm vitality (P < 0.01) and a significant negative correlation with sperm motility (P < 0.05). Elastase concentrations were highly significantly associated with the number of peroxidase-positive cells (P < 0.01) and negatively correlated with sperm vitality (P < 0.01). Moreover, there were significantly negative correlations with sperm motility (P < 0.05), progressive motility according to WHO a quality (P < 0.05) as well as sperm morphology (P < 0.05). In addition, a significant negative correlation was observed between elastase concentrations and percentage of spermatozoa with intact DNA, which may suggest the use of anti-inflammatory treatment. It can be concluded that both IL-6 and granulocyte elastase are useful and suitable as markers for silent genital tract inflammation; in contrast to previous contributions there were clear correlations of IL-6 and granulocyte elastase with sperm parameters, the relationship of elastase with semen quality being more marked. Moreover, the results of the study confirm the need for a change of the threshold value of peroxidase-positive cells according to WHO definition to lower levels for definition of silent genital tract inflammation.

Aetiology of haemospermia.

There are several unknown factors which cause haemospermia. An earlier developed diagnostic scheme has been expended by novel imaging techniques and biopsy methods. A detailed case history, physical examination and microscopic analysis of the ejaculate is required. In haemo-pyospermia a complete microbiological analysis must be escalated. Noninvasive imaging techniques (ultrasound, computer tomography and magnetic resonance imaging) help in detecting calculous and malignant diseases. So far, as a precise diagnosis has not been available, urethroscopy has been performed. Malignancies (prostate, seminal vesicles) must be histologically verified by biopsies. In contempt of our efforts the practice shows a part of haemospermia remaining essential. Analysing two time periods we found prostatic calculi, chronic prostatitis and carcinoma of the prostate unequivocally as most frequent causes. Considering the rare genital malignancies we find more than 10% frequency. Notably, in our study only 2.4% of the malignancies occurred in patients under 40 years of age. Hence a detailed diagnosis is advocated in haemospermia patients over 40 years. Finally, we may state that in contempt of the applied modern imaging techniques 15% of patients with haemospermia had unknown aetiology.

Treatment for potency problems with Afrodor 2000.

The andrological role of the drug Afrodor 2000 (a special mixture of sedatives, aphrodisiacs and vitamin E) in patients with erectile dysfunction is discussed. In the conservative treatment of erectile dysfunction the aphrodisiacs and severe medicine mixtures are widely used. To our practice one of the most useful drugs is Afrodor 2000, mainly for the erectile dysfunction patients of psychological origin.

Hematospermia.

The appearance of blood in the seminal fluid is an alarming sign, with a rather inconstant origin. The causes of hematospermia are discussed based on a review of the literature and the authors' own experience with 84 patients. The importance of differential diagnosis is emphasized and a diagnostic scheme is presented. Therapeutic opportunities depending on etiology are discussed. It is concluded that although hematospermia is an often self-limiting sign, resolving in a few weeks, all patients should undergo a careful investigation to rule out the presence of malignancy or other significant disease.
