The best mode of undescended testis (UDT) treatment remains controversial. However, knowledge gained from randomized controlled studies and meta-analyses allowed different groups of researchers to set out guidelines on management of patients with UDT. The authors reviewed recent literature and came to the following conclusions: (1) Hormonal treatment is not recommended, considering both the immediate results (only 15–20% of retained testes descend) and the possible long-term adverse effects on spermatogenesis. (2) Surgery is the treatment of choice; orchiopexy is successful in about 95% of UDT, with a low rate of complications (about 1%). (3) Orchiopexy should be performed between 12 and 18 months of age, or at first contact if diagnosed later.

There is a theory that the more evident clinical signs of testicular dysgenesis, the more frequent the neoplastic lesions are. The aim of this study was to relate the incidence of testicular germ cell neoplastic lesions (overt germ cell tumours--GCT or testicular carcinoma in situ) to the intensity of testicular organogenesis disturbances (dysgenesis). Biopsies were taken from 154 testes of the following patients: 23 patients with GCT in the contralateral gonad (CGCT), 41 patients with undescended testes operated in childhood (UDT), 90 with azoo-/oligozoospermia (A/O) diagnosed because of infertility. Assessment of seminiferous epithelium, number of Leydig cells, areal fraction of intertubular space (IS), morphometric analysis of seminiferous tubules diameter and thickness of tubular wall were performed. Monoclonal antibodies against placental like alkaline phosphatase and cytokeratin 18 were applied. Germ cell neoplastic lesions were detected in 7.1% of testes and were associated with disturbed spermatogenesis. Among testes with disturbed spermatogenesis they were found the most frequently in CGCT (22.2% vs. 11.1% in UDT and 3.8% in A/O), where spermatogenesis had the highest score (5.7 +/- 3.8 points vs. 4.2 +/- 2.7 in UDT and 4.6 +/- 2.9 in A/O). In CGCT, signs of testicular dysgenesis were less advanced: the highest tubular diameter was 164.4 +/- 32.3 microm vs. 163.5 +/- 28.6 in UDT and 161.4 +/- 31.5 in A/O, the lowest thickness of tubular wall was 8.9 +/- 3.2 microm vs. 10.2 +/- 3.6 in UDT and 10.2 +/- 3.2 in A/O, lowest IS was 36.9 +/- 14.9% vs. 47.9 +/- 18.0 in UDT and 46.5 +/- 18.5 in A/O, and the lowest percentage of tubules with immature Sertoli cells was 0.1 +/- 0.4% vs. 4.9 +/- 7.0 in UDT and 5.2 +/- 9.7 in A/O. Results indicate that neoplastic lesions appear only in testes with disturbed spermatogenesis. Worse condition of spermatogenesis is associated by the presence of other dysgenetic features, but neoplastic lesions appear more frequently in testes with the less advanced features of testicular dysgenesis.

Urogenital tract infections in males are one of the significant etiological factors in infertility. In this prospective study, 72 patients with abnormal semen parameters or any other symptoms of urogenital tract infection were examined. Semen analysis according to the WHO 2010 manual was performed together with microbial assessment: aerobic bacteria culture, Chlamydia antigen test, Candida culture, Ureaplasma and Mycoplasma-specific culture. In total, 69.4% of semen samples were positive for at least one micro-organism. Ureaplasma sp. was the most common micro-organism found in 33% of semen samples of infertile patients with suspected male genital tract infection. The 2nd most common micro-organisms were Enterococcus faecalis (12.5%) and Escherichia coli (12.5%), followed by Staphylococcus aureus (7%), Chlamydia trachomatis (7%) and Candida sp. (5.6%). Generally, bacteria were sensitive to at least one of the antibiotics tested. No statistically significant relationship was observed between the presence of aerobic micro-organisms in semen and basic semen parameters: volume, pH, concentration, total count, motility, vitality and morphology.
