Transcriptómica de la infertilidad masculina

2012

La infertilidad es un problema cada vez más presente en la sociedad actual, especialmente por razones sociales como por ejemplo la postergación de la maternidad por parte de las parejas y en Europa se calcula que afecta alrededor de a 15% de parejas en edad reproductiva. Las causas de la infertilidad son muchas y pueden afectar a uno sólo de los miembros o a ambos, además su etiología es diversa y a veces es desconocida. Las técnicas de reproducción asistida nacieron como consecuencia de estos problemas acuciantes y desde sus inicios han ido mejorando e innovando para mejorar cada vez más sus tasas de éxito. El mayor éxito en estas técnicas radica en la investigación de los factores que int…

Spermiogram and sperm head morphometry assessed by multivariate cluster analysis results during adolescence (12-18 years) and the effect of varicocele

2016

Artículo científico This work evaluates sperm head morphometric characteristics in adolescents from 12 to 18 years of age, and the effect of varicocele. Volunteers between 150 and 224 months of age (mean 191, n = 87), who had reached oigarche by 12 years old, were recruited in the area of Barranquilla, Colombia. Morphometric analysis of sperm heads was performed with principal component (PC) and discriminant analysis. Combining seminal fluid and sperm parameters provided five PCs: two related to sperm morphometry, one to sperm motility, and two to seminal fluid components. Discriminant analysis on the morphometric results of varicocele and nonvaricocele groups did not provide a useful class…

Ability of the ISAS3Fun Method to Detect Sperm Acrosome Integrity and Its Potential to Discriminate between High and Low Field Fertility Bulls

2021

The objective of the present study was to investigate whether fertility differences in bulls are reflected in variations of sperm quality when analysing only one ejaculate per male. Two experiments were performed. In the first experiment, frozen semen samples from 20 adult bulls were tested
