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

Effects of Cannabinoids on Sperm Morphology
Pharmacology, 2008Sperm morphology was studied in hybrid mice of genotype (C57BL x C3H)F<sub>1</sub> following treatment with specific cannabinoids. Mice were treated for 5 consecutive days with the specific cannabinoid; 35 days after the last treatment, epididymal sperm were scored in the light microscope and assessed in the scanning electron microscope ...

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.

Sperm morphology and male urogenital infections
Andrologia, 2009The aim of this study was to investigate the influence of urogenital infections as indicated by leukocytospermia on human sperm morphology, diagnosed cytologically and by means of a leukocyte peroxidase test. A basic semen analysis, including a leukocyte peroxidase test, was prospectively performed on 150 consecutive semen samples. Cytology smears were
