The significance of sperm DNA oxidation in embryo development and reproductive outcome in an oocyte donation program: a new model to study a male inf…
2008
Objective: One byproduct resulting from free radical damage is the DNA hydroxylation also known as DNA oxidation. Our aim with this work was to determine the relevance of sperm DNA oxidation on embryo quality in oocyte donation cycles. Design: We prospectively studied pairs of oocyte donation cycles, i.e., the same oocyte donors, donating to two recipients, where the only difference between the two treatments was the use of a different sperm sample. Setting: University-affiliated private IVF setting. Patient(s): Infertile male partners from couples undergoing oocyte donation cycles (n=38): 76 semen aliquots analyzed before and after semen processing by swim up. Intervention(s): None. Main O…
CASA-Mot in mammals: an update
2017
Sperm motility is one of the most widely used parameters of sperm quality. Computer-aided sperm motility analysis (CASA-Mot) systems were developed to reduce the subjectivity of sperm motility assessment, and have had broad scientific and practical acceptance. In this review, the sources of variation and current applications of this technology and its relationships with other sperm quality tests are described in detail. Despite remarkable advances in the technique, there is still great need for standardisation in many species, and the numerous factors that affect the results make it difficult to provide universally accepted criteria for classifying semen samples based on sperm motility char…
Personality Traits Increasingly Important for Male Fertility: Evidence from Norway
2014
We study the relationship between personality traits and fertility using a survey of Norwegian men and women born from 1927 to 1968 (N = 7017 individuals). We found that personality relates to men's and women's fertility differently; conscientiousness decreases female fertility, openness decreases male fertility and extraversion raises the fertility of both sexes. Neuroticism depresses fertility for men, but only for those born after 1956. The lower male fertility in younger cohorts high in neuroticism cannot be explained by partnership status, income or education. The proportion of childless men (at age 40 years) has increased rapidly for Norwegian male cohorts from 1940 to 1970 (from abo…

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
