To examine the effects of ingested snakeweed foliage (SW) on male fertility and reproduction, SW collected at prebloom stage was dried, ground, and mixed with ground commercial rat feed (CRF) as 0, 12.5, and 25% of total diets. Male rats fed SW for 20 d impregnated females as successfully as did dietary controls, but males fed 12.5 or 25% SW for 40 d had seemingly impaired fertility and apparen...

Background: Acrylamid (AA) is found in carbohydraterich foods that are prepared at high temperatures, such as French fries and potato chips. The toxic effects of AA in male animals include degeneration of epithelial cells of seminiferous tubules, decreased number of sperm and elevation in abnormal spermatozoa. The aim of this study was to evaluate the detrimental effects of AA on sperm paramete...

OBJECTIVE To explore the possibility of using the L4 membrane filtration device for processing of spermatozoa for intrauterine insemination and other assisted reproductive techniques. DESIGN, SETTING, PATIENTS Semen samples from 15 patients attending an infertility clinic of a tertiary referral institution and from seven fertile donors were used for the study. MAIN OUTCOME MEASURES The effe...

in 30–50% of sub-fertile couples the male partner has poor semen quality, either because of low sperm count, poorly motile sperm or sperm with abnormal size and shape (morphology). This may result from inherent genetic factors, poor pre-natal testicular development or adult exposure to gonadotoxic agents. There are few proven therapies to improve semen quality. Therefore, the number and quality...

The in vivo cytogenetic effects of 2-trans hexenal were evaluated by investigating chromosomal aberrations and sperm head abnormalities in the bone marrow cells of laboratory bred Swiss albino mice. Single intraperitoneal injections of 8, 16 or 32 μl per kg bodyweight resulted in dose-dependent decreases in the mitotic index, significantly so at the higher doses and earlier times. Chromosomal a...

Inguinal varicocelectomy was performed on 27 selected infertile males with Grade III varicoceles. Follow up was effected for eighteen months. 18 (66%) patients recorded improvement in sperm count to above (20 X 10(6)/ML). 17 (63%) patients recorded improvement in active sperm mortility to above 40%. 15 (55%) patients showed diminution in the level of abnormal sperms to less than 30% abnormal fo...

Genotoxic effects of EMS have been assessed in fish, A. testudineus, using widely accepted cytogenetic protocols like chromosome aberrations, nuclear anomalies in red blood cells and abnormal sperm head morphology. In addition, gel electrophoretic protein profiles and total protein contents in nine selected tissues were analysed for evaluating their utility as potential indicators of genotoxici...

Genetic sperm defects are specific sperm defects, which have been shown to have a genetic mode of transmission. Such genetic linkage, either direct or indirect, has been associated with a number of sperm defects in different species, with this number increasing with improved diagnostic capabilities. A number of sperm defects, which have proven or suspected genetic modes of transmission are disc...

Dunaliella salina, lycopene and vitamin A Carotenoids especially betacarotene, vitamin A and lycopene have been shown to boost sperm parameters [2-5] Dunaliella salina is a microalgae which is a naturally rich source of mixed carotenoids including lycopene [6] Betacarotene, lycopene and vitamin A can reduce sperm DNA fragmentation and lipid peroxidation [1, 2] Vitamin A is an essential nutrient...
