Abnormal meiotic recombination in infertile men and its association with sperm aneuploidy.
Defects in early meiotic events are thought to play a critical role in male infertility; however, little is known regarding the relationship between early meiotic events and the chromosomal constitution of human sperm. Thus, we analyzed testicular tissue from 26 men (9 fertile and 17 infertile men), using immunofluorescent techniques to examine meiotic chromosomes, and fluorescent in situ hybri...
متن کاملSperm aneuploidy rates in younger and older men.
BACKGROUND In order to assess the possible risk of chromosomal abnormalities in offspring from older fathers, we investigated the effects of age on the frequency of chromosomal aneuploidy rates of human sperm. METHODS AND RESULTS Semen samples were collected from 15 men aged <30 years (24.8 +/- 2.4 years) and from eight men aged >60 years (65.3 +/- 3.9 years) from the general population. No s...
متن کاملImpact of DNA Damage on the Frequency of Sperm Chromosomal Aneuploidy in Normal and Subfertile Men
Background: Various frequencies of sperm aneuploidy are reported in sperms of subfertile patients compared to normal individuals. Moreover, sperm DNA damage is shown to be associated with male infertility. In this study, the rate of DNA damage and frequencies of aneuploidy in sperms of subfertile patients was investigated. Methods: Semen samples were obtained from healthy normal and subfertile ...
متن کاملSperm morphology, motility, and concentration in fertile and infertile men.
BACKGROUND Although semen analysis is routinely used to evaluate the male partner in infertile couples, sperm measurements that discriminate between fertile and infertile men are not well defined. METHODS We evaluated two semen specimens from each of the male partners in 765 infertile couples and 696 fertile couples at nine sites. The female partners in the infertile couples had normal result...
