SPERM ABNORMALITIES AND CIGARETTE SMOKING

Lancet, The, 1981
Sperm samples from a carefully matched group of 43 cigarette smokers and 43 non-smokers attending an infertility clinic were examined for morphological abnormality. The smokers were found to have a significantly greater percentage of abnormal forms. In the light of other work showing increased chromosome damage in blood lymphocytes of cigarette smokers

The relationship between sperm chromosomal abnormalities and sperm morphology in humans

Mutation Research-Fundamental and Molecular Mechanisms of Mutagenesis, 1988
It has been suggested that an assay for sperm morphology might prove useful as an initial screen in evaluating men at risk for an increased frequency of sperm chromosomal abnormalities. In this study, the technique for analysis of human sperm chromosomes after penetration of hamster eggs was employed to determine whether there is an association between

Major morphological sperm abnormalities in the bull are related to sperm DNA damage

Theriogenology, 2011
The influence of sperm morphology and chromatin integrity on bull fertility suggests a strong but undefined biological relationship between these two parameters. In this study we explore this relationship, making use of the Sperm Chromatin Dispersion test, which allows simultaneous observation of sperm abnormalities and DNA fragmentation.

Chromosomal abnormalities in sperm

Molecular and Cellular Endocrinology, 2001
The use of FISH (fluorescent in situ hybridization) in decondensed sperm nuclei has allowed, during the last decade, to indirectly study the chromosome constitution of human spermatozoa. Studies in control populations have been used to set up the basal level of aneuploidy for all human chromosomes and, based on conservative estimates, the percentage of

Sperm head abnormality test

Mutation Research/Genetic Toxicology, 1982
Abstract Benzyl chloride, 4-chloromethylbiphenyl and 4-hydroxymethylbiphenyl either subcutaneously or intraperitoneally at up to lethal doses did not induce a positive response in mice in the sperm head abnormality assay in mice.

Morphological abnormalities in zebrafish cryopreserved sperm

Cryobiology, 2020
The aim of the present study was to evaluate the effect of cryopreservation on the morphology of zebrafish sperm (Danio rerio). Sperm from 30 males were collected and divided in two treatments: fresh and cryopreserved semen. The following were measured sperm morphology, motility and membrane integrity.

Abnormal morphology of vervet monkey sperm

Journal of Medical Primatology, 1996
Abstract: Ejaculates of 14 colony‐bred and 14 wild‐caught vervet monkeys were examined for morphologically abnormal sperm. Sperm head abnormalities were rare in both groups, occurring at rates of 0.01–0.29%. Tail abnormalities predominated, particularly bent midpieces and coiled and folded tails, which all occurred at rates of 3.79–17.18%.
