In order to assess the relative incidence of varicocele (V) alone and V+ coincidental didymo-epididymal morphological abnormalities (DEMA) and the role of these pathologies on the pre- and post-surgical sperm outcome, 151 selected (previous exclusion of cases with bilateral V, seminal infections, antisperm autoAb) patients (aged 20-41 yrs) affected by left V at Doppler ultrasonography, underwent both ultrasound scrotal content examinations and semen analyses (sperm density, total sperm count, forward motility and normal morphology employing as frequency distribution) before and after varicocelectomy (on months 4-8-12, taking for statistical comparison the maximal post-surgical sperm value registered vs. mean correspective pre-treatment value). One-hundred two (67.5%) patients exhibited V alone (group A), whilst 49 (32.5%) patients showed V+DEMA (group B). As regards V, DEMA lesions (testis size < 12 ml; epididymides abnormalities: increased head (> 11 mm) and/or tail (> 6 mm) diameter, multiple microcysts; large idrocele) were omolaterally in 21/49 (42.8%) eterolaterally in 11/49 (22.5%) or bilaterally in 17/49 (34.7%). An additional group of 25 patients, exhibiting the above ultrasonic DEMA lesions alone without V, served as controls (group C) for semen statistical analysis in the pre-surgical period only. In this phase among groups A vs B, A vs C, B vs C, frequency distributions of all sperm parameters studied (excepted for density not significative only between B and C group patients) were significantly different. The following data were registered from A, B and C patient groups respectively: a) azoospermia was present in 12.7%, 34.8% and 24%; b) oligozoospermia (< 20 mil/ml) in 39.2%, 49% and 48%; c) normozoospermia in 48.1%, 16.3% and 8%; d) total sperm count was < 40 millions/ejaculate in 44.1%, 91.9% and 76%; e) asthenozoospermia (forward motility < 25%) was present in 32.3%, 71.4% e 72%; f) teratozoospermia (oval form <30%) was present in 34.3%, 62.3% and 48%. In the post-surgical follow-up examinations, significative changes with ameliorated frequency distributions of all semen parameters were observed within group A only, while these same parameters remained unmodified within group B patients, thus being together a significative difference between groups A vs B higher than that observed in the pretreatment. The coexistence of DEMA+V seems to determine two important effects on sperm output: a) in the pre-treatment, this selection judgement allowed to distinguish a different frequency distribution of semen parameters between patients affected by V alone and V+DEMA; b) since patients with V alone in comparison with V+DEMA patients groups had a favourable sperm outcome, the assessment of DEMA in patients with V seems to be mandatory for a better sperm prognostic judice.
