Empirical treatment of low-level leukocytospermia with doxycycline in male infertility patients.

OBJECTIVE: To design a retrospective study in which infertile men with a seminal leukocyte count of 0.2-1 × 10(6) white blood cells [WBC]/mL were given doxycycline to examine the potential benefits of the treatment on the improvement of semen parameters and natural pregnancy outcomes. It has been reported that even low-level leukocytospermia (0.2-1.0 × 10(6) WBC/mL) could be harmful to male reproductive function and achievement of pregnancy. METHODS: The records of 223 patients were reviewed and 61 patients were identified with a leukocyte count of 0.2-1.0 × 10(6) WBC/mL. Of the 61 patients, 27 presented before 2006 and were not routinely treated for this level of leukocytospermia. These patients were our historic control population. Since 2006, 34 patients met these criteria and received empirical antibiotic therapy (treatment group). RESULTS: The treatment of low-level leukocytospermia with doxycycline did not show statistically significant differences in the semen parameters among the treated patients. Although the therapy did not alter the semen parameters, low-level leukocytospermia resolved in 56% of the treatment group, well above the spontaneous resolution rate of 25% observed in historic controls. The natural pregnancy rate among the treatment group (15 of 32 [47%]) was significantly greater than that among the controls (5 of 25 [20%]). The odds ratio for pregnancy outcome was 3.7 (95% confidence interval 1.1-11.7; P = .04). CONCLUSION: Low-level leukocytospermia might have deleterious effects on male fertility, and antibiotic therapy for such a condition might improve the natural pregnancy rate among infertile couples.

Does severe teratozoospermia affect blastocyst formation, live birth rate, and other clinical outcome parameters in ICSI cycles?

OBJECTIVE: To determine if strict morphology correlates with outcome parameters in couples undergoing intracytoplasmic sperm injection (ICSI). DESIGN: Retrospective review. SETTING: Academic nonprofit IVF center. PATIENT(S): Couples undergoing IVF/ICSI. INTERVENTION(S): In vitro fertilization and ICSI. MAIN OUTCOME MEASURE(S): Samples were evaluated for total sperm count, motlity, progression, and morphology using Kruger's strict criteria. The ICSI cycle outcome parameters included fertilization, clinical pregnancy, implantation, live birth, and blastulation rates and blastocyst quality. RESULT(S): Fertilization rates were high (74%-77%), and clinical pregnancy rates ranged from 60% (subgroup with 0% normal sperm) to 56% (subgroup with >/=7% normal forms). The highest pregnancy and live birth rates were observed in eggs fertilized with sperm from specimens with the most severe teratozoospermia. The blastulation rate was similar among subgroups. The percentage of high-quality blastocysts was significantly greater in the severely teratozoospermic patients compared with patients with >/=5% normal sperm (37% vs. 28%). This is likely because in the lower morphology subgroups, female factors are less prevalent and the primary infertility problem is male factor. CONCLUSION(S): These data suggest that we reconsider the diagnostic value of strict morphology in assisted reproductive technology cycles involving ICSI. Sperm morphology assessed by Kruger's strict criteria had little prognostic value in ICSI cycle outcomes. Sperm morphology did not appear to influence blastocyst development or blastocyst morphology. Microscopic selection of sperm with "normal" morphology during the ICSI procedure allowed excellent outcomes even in samples with severe teratozoospermia.

Advances in microsurgery and assisted reproduction for management of male infertility.

Microsurgical techniques are often used for reconstruction of the male genital tract in order to restore fertility. Advances in technology have led to improved outcomes for patients and men previously felt to be incapable of fathering children are now biologic parents. Use of the operating microscope has led to improved outcomes in vasectomy reversal and has made possible the connection of the vas deferens to a single delicate epididymal tubule. In addition to advances in the area of magnification, novel techniques such as robotic assisted surgery or use of biologic sealants hold promise for further refinement. New surgical techniques and high power magnification has enabled surgeons to find isolated areas of sperm production in testicles of patients that previously were felt to make no sperm at all. In this article we will review the indications, outcomes, and technological advances in the various microsurgical procedures to treat male infertility are.

Varicocele repair: does it still have a role in infertility treatment?

PURPOSE OF REVIEW: To review the role of varicocele repair in the treatment of male infertility. RECENT FINDINGS: Varicocele is a common finding among men with infertility and its repair has been a mainstay of surgical therapy in these men. Although each year multiple discoveries are made concerning the mechanism of varicocele-induced infertility, the exact pathophysiologic mechanism remains unknown. This study will update significant findings in regard to the pathophysiology of varicocele-induced infertility, such as increased expression of the aquaporin receptor and new findings related to testicular blood flow and vas deferens motility. Recent information concerning the effects of apoptosis and oxidative stress are also reviewed. With regard to the efficacy of varicocele repair, previous meta-analysis of the available data has been misleading due to improper selection criteria. Available clinical data are critically evaluated, with a focus on new meta-analyses that contradict the findings of the Cochrane database review, a study that has been accepted by many as evidence against varicocele repair. SUMMARY: We conclude that varicocele repair not only is an effective treatment for appropriately selected patients but can also be the most cost effective option.

Minority issues in prostate disease.

This article has discussed the increased incidence and disproportionately increased mortality of prostate cancer among African American men.Although the exact reasons are unknown, genetics may play a role, in addition to health care practices. Morbidity from other disease states, such as diabetes, obesity, or hypertension, may influence the overall survival of patients with prostate cancer. Current research tools will continue to explore biologic differences between the races; however, socioeconomic status and access to health care must not be overlooked. Several studies have demonstrated that similar disease stages and equal access to health care will result in similar outcomes. It is recognized that screening for prostate cancer will remain a controversial topic. Several influential professional societies recommend against screening and other professional societies endorse screening. Large-scale trials are currently underway hoping to answer this critical question. Since the advent of current screening tools, however, it seems that the overall mortality for prostate cancer has decreased and this cannot be ignored. Certainly, screening programs and clinical trials have traditionally had difficulty in recruiting minority participants, although more recent trials seem to be finding success. A primary care physician who is viewed as competent by their patients can certainly have a positive impact on their African American patients' willingness to participate in studies and screening programs. Most importantly, on the individual level, primary care physicians can provide a great service to their minority patients by offering educational materials on prostate cancer and by offering screening to qualified patients. The current American Urologic Association and National Cancer Institute guidelines recommend offering screening to all men age 50 and above. African American men or men with a first-degree relative with prostate cancer should be offered screening beginning at age 40. Proper screening consists of both a digital rectal examination to assess for asymmetry or nodules of the prostate and a serum PSA. Current recommendations are that individuals with a serum PSA greater than 4 ng/mL ora prostate nodule or asymmetric prostate should be referred to an urologist,where a biopsy can be performed easily in the office setting.The PSA cutoff of 4 has recently been questioned. A study by Thompson et al [31] evaluated 2950 men with a PSA of 4 or less with prostate biopsy.They found that the risk of prostate cancer in men with a PSA between 3.1 and 4 was 26.9% and that 25% of these men with prostate cancer had high-grade disease. All men found to have cancer had T1 disease. The clinical relevance of this surprisingly high rate of prostate cancer in men with a normal PSA is yet to be determined and is pending in studies on the ultimate effect of screening on mortality from prostate cancer. This information is not intended to confuse the issue, but intended to provide the most up-to-date information and allow for the best clinical decision making by the primary care physician. What can currently be recommended is if a patient is concerned about his possibility of having prostate cancer despite a normal PSA, a referral to an urologist to at least further discuss the issue may be in order. This may be especially true if the patient is African American or has a family history of prostate cancer at an early age.

Genital and perineal burns in children: 10 years of experience at a major burn center.

PURPOSE: The aim of this report is to review a decade of experience in the management of perineal and genital burns at a major burn center. METHODS: Seventy-eight children who sustained perineal or genital burns admitted to the Shriners Hospitals for Children in Galveston are discussed. RESULTS: Genital and perineal burns occurred in the context of major burns and were rarely isolated. A total of 64.1% were caused by hot liquids (scalds), 29.5% were flame burns, 3.8% contact burns, and 2.6% electrical burns. A total of 61% of the burns could be treated conservatively with loose debridement, topical, and parenteral antibiotics with satisfactory outcomes. Foley catheterization did not increase the morbidity in these patients except in children less than 1 year of age. Testicular involvement was associated with the most severe burns. Child abuse was found in 46% and 48% of boys and girls, respectively, younger than 2 years that had sustained scald burns to the perineum and, or genitals. CONCLUSIONS: Most perineal and genital burns in children can be treated successfully with a conservative approach. Child abuse should be vigorously investigated.
