Objective: To evaluate semen quality of men with proven fertility in Spain over the last 3 decades., Methods: We conduct a retrospective analysis of ejaculate samples of 992 men between 1985 and 2009. All patients had proven fertility as demonstrated by fathering at least 2 children and a semen analysis performed before they underwent vasectomy. A standardized procedure was used for the semen analysis. Semen volume, total sperm count, sperm concentration, motility, and percentage of morphologically normal spermatozoa were assessed. Mean values were calculated by examining microscopic fields of 100 spermatozoa., Results: Statistically significant differences were found in all semen parameters analyzed. For the periods 1985-1990, 1990-2000, and 2000-2009, the mean (standard deviation [SD]) sperm concentration was 27.7 (22.97), 20.73 (14.79), and 20.18 (20.79) × 10(6) (P <.0001). The mean (SD) progressive motility for each period was 53.19 (20.35), 47.22 (15.84), and 40.57 (15.15; P <.0001). The mean (SD) normal-shaped spermatozoa for each period was 67.69 (10.24), 58.87 (14.67), and 51.02 (15.76; P <.0001). Multivariate analysis using a logistic regression model showed that age had no significant effect in the variation of semen parameters at the cut-points analyzed, except for normal forms at percentile 25 (P = .001). Multivariate analysis revealed a trend for decline of semen in sperm concentration, progressive and nonprogressive motility, and the percentage of morphologically normal spermatozoa (P = .001-.002)., Conclusion: Over the last 3 decades, a decline in semen quality was found in all the parameters analyzed in Spanish men with proven fertility., (Copyright © 2015 Elsevier Inc.

Objective: To detect current errors within the administration of phosphodiesterase type 5 inhibitors (PDE5is) and evaluate and elucidate what percentage of patients could be recovered for oral therapy with different subtypes of PDE5is through a re-education program., Methods: Two hundred fifty patients remitted to the andrology unit were prospectively analyzed. Patients' chief complaint was erectile dysfunction despite treatment with PDE5i. The International Index of Erectile Function was used to measure erectile function. A structured interview was developed to evaluate the most frequent errors within the administration of PDE5is. A re-education program was offered to patients with incomplete or incorrect use of PDE5is according to the structured interview, classifying them into true nonresponders or false nonresponders. Finally, the percentage of patients who could be recovered for oral therapy with other PDE5is was analyzed., Results: A total of 172 patients (69%) presented some error within drug administration. The most common error was not trying >1 PDE5i (41%). A re-education program was offered to these nonresponders, and 115 (66.9%) accepted. Up to 27 (23.5%) did not respond to the re-education program and were classified as true nonresponders, whereas 88 (76.5%) had a positive response to treatment and were thus included in the false nonresponder group., Conclusion: Two-thirds of patients remitted to our andrology unit and cataloged as nonresponders were in fact using PDE5i in suboptimal conditions. Offering patients more accurate information provided almost 76% with good results using PDE5is and could therefore be successfully treated with these drugs., (Copyright © 2014 Elsevier Inc.
