ABSTRACT

A infertilidade é um problema que afeta cerca de 10%-20% da população, com incidência variável em todo o mundo. A avaliação do casal infértil é geralmente indicada depois de um ano, tempo em que a maioria dos casais normais teria sido bem sucedida na tentativa de concepção. Algumas investigações são controversas, e, na presença de múltiplos métodos, o custo, a segurança e a conveniência deveriam ajudar a decidir o mais apropriado.


Infertility is a problem affecting approximately 10%-20% of the population with variable incidences across the world. Evaluation of a couple is generally indicated after one year, by which time most normal couples attemptiong conception would have been successful. Some of the investigations are controversial and in the presence of multiple methods of investigating one aspect, the cost, safety, convenience and evidence-base should help in deciding on the appropriate method.

ABSTRACT

The success of any infertility management programme is reflected in its efficacy to achieve a pregnancy either spontaneously or through assistance. For this purpose some routine investigations are carried out to pinpoint the nature of problem(s) which an infertile couple is troubled with. As the basic requisite for conception to occur is the accumulation of motile spermatozoa around the egg at the site of fertilisation, proper assessment of sperm transit from the vagina to the tubal ampulla becomes a very important criterion to predict the possibility of spontaneous pregnancy. Till date postcoital test was the sole investigative tool available to serve this purpose but unfortunately it fails to furnish any information about the concentration and nature of quality of spermatozoa beyond the cervix. This results in the disparity between postcoital test results and pregnancy outcome. In the present study intra-uterine fluid was examined along with cervical mucus 4-6 hours postcoitus in the pre-ovulatory period. The objective was to gather information about the fate of spermatozoa subjected to the uterine environment after being vaginally deposited during coitus. The result of this combined test has been found to be very much informative and helpful for the fertility physician to set the criteria for timed intercourse and / or intra-uterine insemination. This simple test thus appears to play a leading role in infertility management in near feature.

ABSTRACT

A vulvovaginite, expressäo de diversas patologias que acometem o trato genital inferior feminino, é conhecida desde Hipócrates e Soranus como importante manifestaçäo de distúrbios potencialmente graves para a saúde genital e sistêmica das mulheres. Vários trabalhos já enfocaram com muita ênfase, os aspectos microbiológicos destas doenças, porém pouca coisa tem sido feita em funçäo dos fatores coadjuvantes que poderiam favorecer ou dificultar a instalaçäo das mesmas. Neste artigo säo enfocados os aspéctos bioquímicos e nutricionais do conteúdo vaginal fisiológico, dando uma descriçäo dos achados mais frequentes, bem como as possíveis interaçöes com a microflora. Os mecanismos de proteçäo ou de facilitaçäo do corrimento vaginal säo apontados, estressando a importância dos aminoácidos e imunoglobinas, secretadas principalmente a nível local. O conhecimento de tais aspectos, pode servir como chave importante para o ginecologista estabelecer uma correlaçäo entre os achados clínicos e laboratoriais e conseqüentemente elucidar a açäo fisiopatogênica em determinados casos, base fundamental para o perfeito diagnóstico e tratamento

ABSTRACT

Los objetivos del presente trabajo fueron: 1) Conocer el patrón (duración y frecuencia) del reflejo de Flehmen (RF) del toro en respuesta a mustras de moco cérvicovaginal obtenidas el día 0 del ciclo estral. 2) Conocer el patrón del RF del toro en respuesta a improntas cérvicovaginales obtenidas los días 3, 6, 9, 12, 15, 16, 17, 18, 19, 20 y 21 posestro y determinar si existen diferencias entre estos días. 3) Conocer el patrón del RF del toro en espuesta a muestras de leche obtenidas los días 0, 3, 6, 9, 12, 15, 16, 17, 18, 19, 20, 21, posestro y determinar si existían diferencias entre dichos días. En cada experimento se registró con un cronómetro la duración y frecuencia con que se daba el RF en un tiempo de exposición a la muesta de dos minutos. Se encontró una diferencia estadística significativa (P < 0.05) entre los valores promedio obtenidos respeto a la duración y frecuenia del RF durante los días del ciclo estral evaluados con muesras de moco e impronta cervicovaginal, así como con las muestras de leche. Los resultados obtenidos sugieren que la capacidad de estos fluidos para inducir el RF en el toro varía según la etapa del ciclo estral en que se encuentran las vacas y que en consecuencia las características olorosas de dichos fluidos varían según la ciclicidad ovárica. Este trabajo concuerda con estudios previos en el sentido de que el toro es capaz de predecir el inicio del estro de la vaca, incluso con varios días de anticipación, por medio del análisis olfativo de olor característico de las excreciones de la hembra.

ABSTRACT

O trabalho analisa o valor preditivo do teste de penetraçao dos espermatozóides no muco cervical bovino (TMCB) e a posterior performance no teste pós-coito (TPC). O total de 31 casais foi analisado. Inicialmente, os maridos realizaram o TMCB, em seguida, suas esposas foram submetidas ao TPC. Os resultados obtidos mostram que o TMCB anormal identifica com precisao os pacientes que, posteriormente, apresentaram TPC anormal. A eficiência do TMCB foi de 0,73.

ABSTRACT

The time requirement of a routine in-vitro fertilization experiment using human spermatozoa and zona-free hamster oocytes is more than one working day. We have used a simple process of simultaneous sperm washing and capacitation before challenging them against oocytes. Spermatozoa were recovered up to 90 minutes from the proximal end of a column of periovulatory human cervical mucus into Brinster, Whitten and Whittingham's (B.W.W.) medium. Without any further capacitation 50 microliters of these spermatozoal suspension, in the concentration of 2.5-3 X 10(6)/ml, fertilized 81% of a total of 100 eggs. A dramatic decrease in the fertilization rate (18%) was observed when these spermatozoa were further capacitated in-vitro for five hours before actual egg incubation for three hours. Both selection and accelerated capacitation may contribute to this result.
