Semen quality of 324 fertile Japanese men.

BACKGROUND: A number of studies have indicated regional differences in semen quality. To examine the current status in Japan, we undertook a cross-sectional study on the semen quality of fertile Japanese men for comparison with recent European results. METHODS: Semen parameters of 324 fertile men from the Kawasaki/Yokohama area were investigated. The semen parameters were compared with those published for fertile men from four European cities, Copenhagen, Paris, Edinburgh and Turku. RESULTS: When adjusting for confounders such as ejaculation abstinence period and age, the lowest sperm concentrations were detected in men from Kawasaki/Yokohama followed by men from Copenhagen, Paris, Edinburgh and Turku, but only the differences between men from Kawasaki/Yokohama and men from Edinburgh and Turku were significant (P=0.0008 and P<0.0001, respectively). Total sperm count, percentage of motile sperm and percentage of normal sperm observed in Kawasaki/Yokohama were significantly lower than those from all European centres except for motile sperm in men from Paris. CONCLUSIONS: Japanese fertile men had a semen quality at the level of Danish men, who have been reported to have the lowest among investigated men in Europe. The low level of semen quality of the fertile Japanese men may be due to lifestyle or other environmental factors; however, ethnic differences caused by different genetic variation or combinations cannot be ruled out by this study.

Functional anatomy of the prostate: implications for treatment planning.

PURPOSE: To summarize the functional anatomy relevant to prostate cancer treatment planning. METHODS AND MATERIALS: Coronal, axial, and sagittal T2 magnetic resonance imaging (MRI) and MRI angiography were fused by mutual information and registered with computed tomography (CT) scan data sets to improve definition of zonal anatomy of the prostate and critical adjacent structures. RESULTS: The three major prostate zones (inner, outer, and anterior fibromuscular) are visible by T2 MRI imaging. The bladder, bladder neck, and internal (preprostatic) sphincter are a continuous muscular structure and clear definition of the preprostatic sphincter is difficult by MRI. Transition zone hypertrophy may efface the bladder neck and internal sphincter. The external "lower" sphincter is clearly visible by T2 MRI with wide variations in length. The critical erectile structures are the internal pudendal artery (defined by MRI angiogram or T2 MRI), corpus cavernosum, and neurovascular bundle. The neurovascular bundle is visible along the posterior lateral surface of the prostate on CT and MRI, but its terminal branches (cavernosal nerves) are not visible and must be defined by their relationship to the urethra within the genitourinary diaphragm. Visualization of the ejaculatory ducts within the prostate is possible on sagittal MRI. The anatomy of the prostate-rectum interface is clarified by MRI, as is the potentially important distinction of rectal muscle and rectal mucosa. CONCLUSION: Improved understanding of functional anatomy and imaging of the prostate and critical adjacent structures will improve prostate radiation therapy by improvement of dose and toxicity correlation, limitation of dose to critical structures, and potential improvement in post therapy quality of life.

ICSI outcome in patients with transient azoospermia with initially motile or immotile sperm in the ejaculate.

BACKGROUND: In patients with transient azoospermia, few sperm may be found in the ejaculate. We investigated the outcome of ICSI in patients with transient azoospermia. METHODS: Records of patients with transient azoospermia referred during a 42 month period were reviewed. If only immotile sperm were found, the sample was incubated with 30% human serum albumin (HSA) before motility re-assessment. If still immotile, mechanical assessment of sperm viability was utilized. Study groups were: (A) motile sperm; (B) motility achieved by HSA; (C) no motility, but viability assessed by a mechanical technique; and (D) control group with sperm counts from 1 to 5 x 10(6)/ml. There were 57 couples (cycles) in the study group and 43 couples (cycles) in the control group. RESULTS: Age, days of stimulation and endometrial thickness were comparable among groups. In 29.8% of the cycles, only immotile sperm were found. Fertilization and cleavage rates were higher in groups A and D than in groups B and C. Clinical pregnancy rate/cycle and live birth rate/cycle were not different among groups. No congenital malformations were found in newborns. CONCLUSION: Fertilization and cleavage rates were lower in patients with initially immotile sperm compared with those with initially motile sperm and oligoasthenoteratozoospermia patients. Clinical pregnancy and viable pregnancy rates were not statistically different among groups, although when only immotile sperm were present both clinical pregnancy and live birth rate were lower in comparison with cycles with motile sperm.
