Resumo: En el examen del semen son importantes las determinaciones de la movilidad, el número y la morfología espermática, sin embargo no resultan suficientes. La observación de las células de la progenie espermática o de otras células epiteliales puede contribuir al mejoramiento del diagnóstico clínico. En el presente trabajo se presentan tres casos de estudios de muestras de sémenes donde la observación citológica fue el criterio más importante para la definición de la patología. Finalmente se discuten imágenes celulares publicadas en el Manual de OMS para el Examen y Procesamiento de Semen Humano, 5a edición, donde se confunden células germinales inmaduras con macrófagos. El propósito del trabajo es poner en evidencia la importancia del conocimiento citológico para una correcta interpretación de ciertas patologías seminales.

Título: Decline in semen quality among infertile men in Brazil during the past 10 years
Fonte: Int. braz. j. urol;41(4):757-763, July-Aug. 2015. tab, graf.
Idioma: en.
Resumo: ABSTRACTPurpose:To investigate whether the semen quality of men undergoing conventional semen analysis is deteriorating over time.Materials and Methods:We analyzed and compared the sperm count, motility and morphology of 2300 semen samples provided by males undergoing conventional seminal analysis, from years 2000 to 2002 and 2010 to 2012. The incidences of severe oligozoospermia and azoospermia over time were also compared.Results:A total of 764 sperm samples were analyzed in 2000-2002 and 1536 in 20102012. Over time, the mean sperm concentration/ml decreased significantly from 61.7 million in 2000-2002 to 26.7 million in 2010-2012 (R2=11.4%, p<0.001), the total sperm concentration decreased significantly from 183.0 million to 82.8 million (R2=11.3%, p<0.001), and the percentage of normal forms decreased significantly from 4.6% to 2.7% (R2=9.8%, p<0.001). The incidence of severe oligozoospermia significantly increased from 15.7% to 30.3% (OR: 1.09, p<0.001) and the incidence of azoospermia increased from 4.9% to 8.5% (OR: 1.06, p=0.001).Conclusions:This study demonstrated a significant time-related decline in semen quality of infertile patients. This finding might have implications on fertility and emphasizes the need for further studies addressing subject's life-style in order to find and reduce the causative agents. Future prospective and multicenter studies including representative samples of the general population are needed to confirm whether semen quality is really declining.

Resumo: Gait variability is related to functional decline in the elderly. The dual-task Timed Up and Go Test (TUG-DT) reflects the performance in daily activities. Objective To evaluate the differences in time to perform the TUG with and without DT in elderly women with different ages and levels of education and physical activity. Method Ninety-two elderly women perfomed the TUG at usual and fast speeds, with and without motor and cognitive DT. Results Increases in the time to perform the TUG-DT were observed at older ages and lower educational levels, but not at different levels of physical activity. More educated women performed the test faster with and without DT at both speeds. When age was considered, significant differences were found only for the TUG-DT at both speeds. Conclusion Younger women with higher education levels demonstrated better performances on the TUG-DT. .

Alterações da marcha são indícios de declínio funcional em idosos. O TUG com dupla tarefa (TUG-DT) reflete o desempenho das atividades do cotidiano. Objetivo Avaliar as diferenças no tempo de execução do TUG com e sem DT em idosas com diferentes faixas etárias, e níveis de escolaridade e atividade física. Método Noventa e duas idosas foram avaliadas pelo TUG nas velocidades usual e máxima, sem e com DT cognitiva e motora. Resultados Houve aumento no tempo de execução do TUG-DT em idosas com maior faixa etária e menor escolaridade, mas não para diferentes níveis de atividade física. Aquelas com maior escolaridade realizaram o teste mais rápido com e sem DT nas duas velocidades. Com relação à faixa etária, foram obervadas diferenças apenas nos testes com DT nas duas velocidades. Conclusão Idosas mais jovens com maior escolaridade demonstraram um melhor desempenho no TUG com DT. .

Título: Alteraciones del espermiograma en pacientes asistidos en la Unidad de Biología de la Reproducción de la Universidad de Chile / Alterations in the semen analysis of patients attending the reproductive biology unit at the University of Chile
Fonte: Rev. chil. tecnol. méd;32(1):1678-1682, jul. 2012. tab.
Idioma: es.
Resumo: En Chile, 10 a 15 por ciento de las parejas son consideradas como infértiles y el factor masculino es responsable en un 50 por ciento de los casos. El espermiograma, es un examen fundamental para el diagnóstico inicial de parejas infértiles. Objetivo: Determinar cambios en cuatro parámetros del espermiograma de mayor valor diagnóstico, según edad, estableciendo el parámetro alterado de mayor frecuencia. Métodos: Se realizo un estudio descriptivo retrospectivo de una muestra de 100 pacientes atendidos por problemas de fertilidad entre los años 2004 y 2009, clasificándolos en cuatro grupos etarios. Resultados: Al evaluar la concentración espermática, el 33 por ciento presenta: 5 baja concentración. El 86 por ciento de los pacientes presento astenozoospermia. El 81 por ciento de los pacientes presento anormalidad en la morfología espermática. La viabilidad espermática fue anormal en el 8 por ciento de los pacientes, siendo significativamente más alto en el grupo etario de mayor edad. Conclusiones: Los parámetros estudiados muestran un alto porcentaje de anormalidad en la población en estudio. Al comparar entre grupos, el grupo de mayor edad (sobre los 47 &los) presenta un aumento significativo del- porcentaje de alteraciones en morfología, motilidad y viabilidad respecto a los otros grupos etarios, estableciéndose la edad como un factor negativo en la calidad espermática. La movilidad corresponde al parámetro mas frecuentemente alterado seguido por la morfología espermática a medida que el varón consultante envejece.

In Chile, 10 to 15 percent of the couples are considered as infertile. Since the male factor is responsible of 50 percent of the cases, spermogram is an essential test for initial diagnosis of the infertile couple. Objective: To analyze the frequency of change in four spermogram parameters -according to age- to determine their diagnostic value. Method: A descriptive retrospective study of spermogram data from 100 patients -subdivided in four age groups- analyzed in our Unit for fertility problems between 2004 and 2009 was performed. Results: In sperm count, 33 percenr showed an abnormally low concentration. An 86 percent of the patients has astenozoospermia. 81 percent of the patients showed abnormal sperm morphology. Sperm viability was subnormal in 8 percent of the patients, being significantly higher in the oldest group. Conclusions: The seminal parameters analyzed revealed a high percentage of anomalies in the studied population. The oldest group had significant percentages of anomalies in sperm motility, morphology and viability, thus corroborating that age is a negative factor that affects semen quality. Sperm motility was the most frequently altered parameter followed by sperm morphology in the population under study.

Título: Intracytoplasmic spermatid injection and in vitro maturation: fact or fiction?
Fonte: Clinics;68(supl.1):151-156, 2013.
Idioma: en.
Resumo: Intracytoplasmic injection with testicular spermatozoa has become a routine treatment in fertility clinics. Spermatozoa can be recovered in half of patients with nonobstructive azoospermia. The use of immature germ cells for intracytoplasmic injection has been proposed for cases in which no spermatozoa can be retrieved. However, there are low pregnancy rates following intracytoplasmic injection using round spermatids from men with no elongated spermatids or spermatozoa in their testes. The in vitro culture of immature germ cells to more mature stages has been proposed as a means to improve this poor outcome. Several years after the introduction of intracytoplasmic injection with elongating and round spermatids, uncertainty remains as to whether this approach can be considered a safe treatment option. This review outlines the clinical and scientific data regarding intracytoplasmic injection using immature germ cells and in vitro matured germ cells.

Título: The role of varicocele treatment in the management of non-obstructive azoospermia
Fonte: Clinics;68(supl.1):89-98, 2013. tab.
Idioma: en.
Resumo: The literature on male reproductive medicine is continually expanding, especially regarding the diagnosis and treatment of infertility due to non-obstructive azoospermia. The advent of in vitro fertilization with intracytoplasmic sperm injection has dramatically improved the treatment of male infertility due to nonobstructive azoospermia. Assisted reproduction using testicular spermatozoa has become a treatment of hope for men previously thought to be incapable of fathering a child due to testicular failure. In addition, numerous studies on non-obstructive azoospermia have reported that varicocelectomy not only can induce spermatogenesis but can also increase the sperm retrieval rate; however, the value of varicocelectomy in patients with non-obstructive azoospermia still remains controversial. The purpose of this review is to present an overview of the current status of varicocele repair in men with non-obstructive azoospermia.

Título: The importance of semen analysis in the context of azoospermia
Fonte: Clinics;68(supl.1):35-38, 2013. tab.
Idioma: en.
Resumo: Azoospermia is a descriptive term referring to ejaculates that lack spermatozoa without implying a specific underlying cause. The traditional definition of azoospermia is ambiguous, which has ramifications on the diagnostic criteria. This issue is further compounded by the apparent overlap between the definitions of oligospermia and azoospermia. The reliable diagnosis of the absence of spermatozoa in a semen sample is an important criterion not only for diagnosing male infertility but also for ascertaining the success of a vasectomy and for determining the efficacy of hormonal contraception. There appears to be different levels of rigor in diagnosing azoospermia in different clinical situations, which highlights the conflict between scientific research and clinical practice in defining azoospermia.

Título: Update in the evaluation of the azoospermic male
Fonte: Clinics;68(supl.1):27-34, 2013. ilus, tab.
Idioma: en.
Resumo: Approximately 1% of all men in the general population suffer from azoospermia, and azoospermic men constitute approximately 10 to 15% of all infertile men. Thus, this group of patients represents a significant population in the field of male infertility. A thorough medical history, physical examination and hormonal profile are essential in the evaluation of azoospermic males. Imaging studies, a genetic workup and a testicular biopsy (with cryopreservation) may augment the workup and evaluation. Men with nonobstructive azoospermia should be offered genetic counseling before their spermatozoa are used for assisted reproductive techniques. This article provides a contemporary review of the evaluation of the azoospermic male.

Resumo: Evaluar la motilidad y morfología espermática en los estudiantes de la Universidad de Oriente. Se realizó el espermatograma a 100 estudiantes de la Universidad de Oriente, Núcleo de Sucre, Cumaná, Venezuela, y se aplicó a los datos un análisis de regresión lineal simple con un nivel de confianza del 95 por ciento. El 12 por ciento de los estudiantes fueron astenospérmicos, 11 por ciento oligospérmicos y 9 por ciento oligoastenospérmicos. Los astenospérmicos, tuvieron una correlación negativa moderada entre motilidad y anormalidades de la pieza principal (r=-0,58), estadísticamente significativa. En los oligoastenospérmicos hubo una correlación lineal negativa moderada (r=-0,57) entre motilidad y anormalidades de cabeza, estadísticamente no significativa. Se sugiere que la causa probable de alteración de la motilidad progresiva, es por defectos de la cola y exceso de citoplasma residual en espermatozoides de estudiantes astenospérmicos, y anormalidades de cabeza en espermatozoides de oligoastenospérmicos.

To evaluate motility and sperm morphology in students of the Universidad de Oriente. We performed semen analysis to 100 students from the Universidad de Oriente, Nuclei Sucre, Cumana, Venezuela, according to WHO criteria, 1999, and applied to the data a simple linear regression analysis with a confidence level of 95 percent. Diagnosis was 12 percent asthenozoospermic, 11 percent oligozoospermic and 9 percent oligoasthenozoospermic. The asthenozoospermic, had a moderate negative linear correlation between motility and principal piece abnormalities (r =- 0.58) statistically significant. In oligoasthenozoospermic there was a moderate negative correlation (r =-0.57) between motility and abnormalities of the head, not statistically significant. We suggest that the probable cause of altered motility is principal tail defects and excess residual cytoplasm in sperm asthenozoospermic students, and abnormalities in sperm head oligoasthenozoospermic.

Título: Chromosomal and molecular abnormalities in a group of Brazilian infertile men with severe oligozoospermia or non-obstructive azoospermia attending an infertility service
Fonte: Int. braz. j. urol;37(2):244-251, Mar.-Apr. 2011. tab.
Idioma: en.
Resumo: PURPOSE: To determine the frequency of genetic alterations in a population of Brazilian infertile men with severe oligozoospermia or non-obstructive azoospermia. MATERIALS AND METHODS: Retrospective study of a group of 143 infertile men with severe oligozoospermia or non-obstructive azoospermia from the Andrology Outpatient Clinic of the Human Reproduction Service at the ABC School of Medicine. Of these patients, 100 had severe oligozoospermia, and 43 non-obstructive azoospermia. All patients underwent a genetic study which included karyotype analysis and Y-microdeletion investigation. RESULTS: Genetic abnormalities were found in 18.8 percent of the studied patients. Chromosomal abnormalities were found in 6.2 percent of the patients, being more prevalent in the azoospermia group (11.6 percent) than in the oligozoospermia group (4 percent). Chromosomal variants were found in 8.3 percent, and Y-chromosome microdeletions in 4.2 percent of patients. CONCLUSION: The high frequency of genetic alterations (18.8 percent) in our series justified performing a genetic investigation in a population with idiopathic infertility, as results may help determine the prognosis, as well as the choice of an assisted reproduction technique. Moreover, a genetic investigation could minimize the risk of transmitting genetic abnormalities to future generations such as genetic male infertility, mental retardation, genital ambiguity and/or birth defects.
