Sperm morphology training in India
Andrologia, 2014Sperm morphology is regarded as possibly the most consistent sperm variable that is related to in vitro and in vivo fertilisation success or failure. There is also a re-emerging awareness of andrology, particularly in developing countries where healthcare resources are often limited. This study aimed to record the importance of hands-on training on the

Morphology and the sperm penetration assay
Fertility and Sterility, 2003To assess the ability of Kruger morphology to predict the outcome of the sperm penetration assay (SPA).A retrospective review using univariate and multivariate analysis, t tests, and logistic regression was performed to examine the correlation between Kruger morphology and the optimized zona-free hamster egg sperm penetration assay (O-HESPA).University

American Association of Bovine Practitioners Conference Proceedings, 2004
Abnormal spermatozoa have been historically associated with male subfertility and sterility. As early as 1927, an insightful report by Williams and Savage in the Cornell Vet stated that "the dimensions of sperm heads from good fertility bulls are remarkably uniform". This is still true.

Sperm Production and Sperm Morphology of Swedish Warmblood Stallions
Reproduction in Domestic Animals, 2009ContentsThe present study investigated daily sperm output and sperm morphology of fresh semen in eight Swedish Warmblood stallions aged 5–8 years. They were used for artificial insemination, and their fertility during the breeding season of semen collection exceeded 60% per cycle.

Association between sperm morphology and sperm count of boar semen
Polish Journal of Veterinary Sciences, 2023The number of spermatozoa in the ejaculate is important for its quality and that of the sperm contained in it. The number of ejaculated spermatozoa is also associated with sperm dimensions. The aim of this study was to assess the morphological structure of sperm and the frequency of morphological abnormalities in sperm on the ejaculation performance of

Effect of Lead and Organophosphates on Sperm Morphology
Archives of Andrology, 1991Lead and organophosphates can exert a toxic action on the male reproductive function. A cross-sectional study involving 40 men was undertaken to investigate the effect of these toxins on sperm morphology. Based on the percentage of morphologically normal spermatozoa, subjects were divided into two groups.

The relationship between sperm chromosomal abnormalities and sperm morphology in humans
Mutation Research Letters, 1988It 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

Sperm DNA fragmentation is related to sperm morphological staining patterns
Reproductive BioMedicine Online, 2015In this prospective comparative study, sperm DNA fragmentation (sDNAfrag) was compared at each step of a sequential semen preparation, with semen parameters according to their degree of severity. At each step (fractions) of the sequential procedure, sDNAfrag was determined: fresh (Raw), after gradient centrifugation, washing, and swim-up (SU) for 70 ...
