PURPOSE: We evaluated the therapeutic efficacy of finasteride in the treatment of hemospermia, especially in prostatitis-related hemospermia. MATERIALS AND METHODS: Among the patients who visited our urologic department due to hemospermia from Jan 2000 to Oct 2003, 46 patients enrolled in the study. Semen analysis, expressed prostatic secretion, and transrectal ultrasonography were performed for all patients, and we determined whether or not the hemospermia was caused by inflammatory chronic non-bacterial prostatitis. We sorted all the subjects into 2 groups by the use of finasteride or not. We sub-divided the 2 groups by the presence or absence of prostatitis. In each of the 4 groups, the results were compared. Results were also recalculated after excluding sonographically abnormal cases. RESULTS: In the 35 finasteride-treated patients, the prostatitis group showed a 75% (12/16) success rate whereas the non-prostatitis group showed 31.6% (6/19) success. This difference was statistically significant (p=0.01). In the 11 non-finasteride patients, there was no difference in success rate between the prostatitis group (57.1%) and non-prostatitis group (50.0%). After excluding 15 sonographically abnormal patients, the finasteride-prostatitis group showed an 80% (8/10) success rate whereas the non-prostatitis group showed a 25% (3/12) success rate. CONCLUSIONS: Finasteride treatment in hemospermia was more successful in prostatitis than non-prostatitis patients. Efficacy was more prominent after excluding sonographically abnormal cases. Finasteride could be an useful agent in the treatment of prostatitis-related hemospermia. More extensive study is needed.

OBJECTIVE: The goal of this study was to compare the semen parameters of two successive samples obtained within an interval of less than 60 minutes from patients planning to undergo intrauterine insemination (IUI) whose first samples exhibited low semen quality. METHODS: Thirty-two consecutive patients were enrolled in the study. On the day of IUI, the semen analysis of the samples initially presented by all patients met at least two of the following criteria: sperm concentration <5×10(6)/mL, total sperm count <10×10(6), progressive sperm motility (a+b) in the native sample <30%, and total motile sperm count (TMSC) <4×10(6). A successive semen sample was obtained no more than 60 minutes after the first sample. RESULTS: Compared to the first sample, the second exhibited significantly (p<0.05) improved sperm concentration, TMSC, progressive motility, and vitality. Regarding TMSC, the most critical parameter on the day of IUI, 23 patients (71.8%) improved it, while nine (28.2%) displayed poorer outcomes. CONCLUSION: In defined cases, requesting a second successive ejaculate on the day of insemination may result in a high percentage of cases in an improvement of the quality of the sample.

OBJECTIVE: The objective of this study was to compare results of the macroscopic one-layer vasovasostomy with those of microscopic one-layer vasovasostomy and to analyze the change of semen parameters according to the interval of vasal obstruction. METHOD AND MATERIALS: Between March 1987 and December 1997, we performed 121 vasovasostomies using modified one-layer technique with loupe magnification (macroscopic vasovasostomy) or microscope. Among the 68 could be followed post-operatively, 37 patients were treated by macroscopic technique with loupe, and 31 patients by microscopic technique. We compared rates of anatomical patency (sperm count above than 10x106/ml) and pregnancy of macroscopic vasovasotomy with those of microscopic vasovasostomy. Patency and pregnancy fates according to vasal obstructive interval were also examined. RESULTS: The patency rates of macroscopic and microscopic technique were 86.5% and 87.1%, and pregnancy rates of macroscopic and microscopic technique were 64.9% and 67.7%. There was no statistical significance between these two methods (p>0.05). The pregnancy rates and sperm motility were decreased if more than 10 years had elapsed following vasectomy(p<0.05). CONCLUSION: We found little difference in success rates resulting from macroscopic and microscopic vasovasostomy and the former had the advantage of reduced cost and a lower operator skill level. in post-operative semen analysis, the sperm motility was the most probable factor associated with vasal obstructive interval.

PURPOSE: We investigated whether oligospermic or asthenospermic men have decreased testosterone-to-estradiol (TE) ratios and whether this condition can be corrected with an oral aromatase inhibitor. We also determined the predictive value of pretreatment TE ratios for aromatase inhibitor efficacy in infertile men. MATERIALS AND METHODS: From June 2002 to December 2003, a total of 68 subfertile men with abnormal TE ratios were treated with 1 mg of anastrozole daily for 3 months. Changes in serum testosterone, serum estradiol, TE ratios, and semen parameters were evaluated 3 months after this therapy. RESULTS: Men treated with anastrozole had an increase in TE ratios (mean 0.2+/-0.7 [SE] versus 0.38+/-0.15; p<0.001). Semen analysis before and during anastrozole treatment showed an increase in sperm concentration (48.96 versus 70.42 million/mL; p<0.001) and motility (26.3 versus 33.2%; p<0.005). CONCLUSIONS: Men who are subfertile with lower TE ratios can be treated with an aromatase inhibitor with an increase in TE ratios that correlates with improved semen characteristics. We advise that an aromatase inhibitor be used in oligospermic or asthenospermic men if the TE ratio is below 0.2.

A study was conducted in three large populations to determine whether sperm quality has changed in Korea between January 1995 to November 1999. We reviewed sperm concentration, motility and semen volume on two tertiary general hospitals in Korea, data of which collected since 1995 till 1999 according to the WHO guidelines(1987). The data were collected in healthy young Korean men in one center and those who visited urologic clinic in another center, There was no statistically significant difference at each year(p>0.05). Also semen volume and motility were not changed during that times. The data was collected in 1999 in both centers and monthly trends were also compared. No significant change was observed. No changes were observed in the semen parameters analysed in this two distinct populations, showing no evidence of deteriorating sperm quality in Korea over recent years. Furthermore, more data is required to draw any conclusion about the trend of semen qualities in Korea.

PURPOSE: The purpose of this study was to compare the surgical outcomes of two different surgical methods for varicocelectomy, and to assess the effects of varicocelectomy on semen parameters in subinfertile men. MATERIALS AND METHODS: This study included 63 patients with clinically palpable varicocele and abnormal semen parameters who underwent varicocelectomy. Thirty-three patients underwent laparoscopic varicocelectomy, and 30 received microsurgical inguinal varicocelectomy. Semen analyses were performed 5.3 months later, and compared with the pre-operative data. RESULTS: The mean age of patients was 32.1+/-1.3 years old. Comparison of the semen parameters between pre and post-varicocelectomy revealed significant improvement in the sperm count (p<0.05). In laparoscopic and microsurgical inguinal varicocelectomy, the sperm counts were increased from 16.2+/-4.3 to 30.6+/-7.5 and from 15.4+/-3.8 to 37.5+/-7.7, respectively. Sperm motility also tended to improve. CONCLUSIONS: Varicocelectomy enhanced semen parameters after both laparoscopic and microsurgical methods. In subfertile men, early varicocelectomy is recommended.
