The significance and diagnostic value of semen analysis in chronic bacterial prostatitis has been extensively debated and remains controversial. To investigate the diagnostic relevance of semen culture in the bacteriological workup of prostatitis patients, we retrospectively analyzed a clinical database of 696 symptomatic patients. All patients were routinely subjected to a four-glass test, fol...

Background: Testicular cancer (TC) is usually diagnosed after manifestation of an overt tumour. Tumour formation is preceded by a pre-invasive and asymptomatic stage, carcinoma in situ (CIS) testis, except for very rare subtypes. The CIS cells are located within seminiferous tubules but can be exfoliated and detected in ejaculates with specific CIS markers. Materials and Methods: We have built ...

semen analysis, sperm dna fragmentation (sdf) and hypo-osmotic swelling test (host) are usually performed for the evaluation of sperm fertilizing ability. there are some debates over the necessity of sdf and host incorporation in male infertility work-up.semen of 77 men was evaluated by sdf and host through three semen analyses. sperm parameters were arranged into different categories: < 5%, 5-...

Semen analysis is the first test requested when fertility potential of a man becomes questionable. The results of the semen analysis are often taken as a surrogate measure of his ability to father a pregnancy. The test provides information on the functional status of the seminiferous tubules, epididymis, seminal vesicles, and the prostate. Thus the results of the test should be interpreted in t...

It has been documented that almost 50% of the infertility problems are at present attributed to male factors. In IVF centres, potential infertile men are screened for the sperm quality by semen analysis, in particular investigating concentration, motility and morphology according to WHO guidelines [1]. However, at present, these parameters appear to be poor predictors of the fertilization succe...

A practical approach to semen analysis (SA) interpretation and the initial management of subfertile men is presented. Each parameter of the SA is described and management recommendations based upon SA findings are provided. The indications for and interpretation of adjunctive diagnostic testing for male factor subfertility are also discussed.

In more than half of infertile men, the cause of their infertility is unknown. Several studies revealed the role of viral infections in male infertility. The aim of the present study was to determine the prevalence of herpes simplex virus-1 (HSV-1) and HSV-2 in semen from asymptomatic infertile male patients, and its association with altered semen parameters. A total of 70 semen samples were co...

The aim of this study, based on a prospective analysis, was to evaluate the accuracy of the TEST-yolk buffer enhanced hamster egg penetration test (HEPT) and acrosin activity in discriminating fertile from infertile males as compared with the conventional semen profile. The incidence of spontaneous pregnancies was monitored during a follow-up period ranging between 18-24 months in 62 couples wi...
