Distribution of alpha-, gamma (+beta)- and delta-tocopherol in the seminal plasma, spermatozoa and seminal vesicles of rabbit.
Dietary vitamin E supplementation plays a key role in animal reproduction by protecting germ cells from oxidative damage. Recently, alpha-tocopherol homologues (namely, beta-, gamma- and delta-tocopherol) have been the object of increasing research because of their peculiar nonantioxidant properties. We found that these tocol-derived compounds are not homogeneously distributed among semen compo...
متن کاملPhospholipids of bovine spermatozoa and seminal plasma.
Spermatozoal and seminal plasma lipids of fourteen individual bulls were separated by column chromatography into neutral lipid and several phospholipid fractions. Elution progress was monitored by thin-layer chromatography. Each phospholipid constituent was determined by phosphorus analysis. Total lipid, cholesterol and plasmalogen contents were determined. The fatty acids and aldehydes of the ...
متن کاملEffect of seminal plasma on the characteristics and fertility of rabbit spermatozoa.
The effects of different dilutions of seminal plasma (SP) on the qualitative characteristics of rabbit spermatozoa and on their fertilising ability were analysed. Ejaculated semen was centrifuged twice and the sperm resuspended in media with decreasing ratios of SP/Tris: (1/2; 1/5; 1/10; 1/20; 1/30; 1/100) until the complete substitution was with SP. The control constituted sperm in undiluted S...
متن کاملImmunological differentiation of epididymal and seminal spermatozoa of the rabbit.
Rabbit spermatozoa from the epididymis lack the antigenic material present on seminal spermatozoa, which these latter cells have in common with the seminal plasma. This observation provides further support for the indirect evidence, obtained previously, that antigenic material is taken up by the spermatozoa from the seminal plasma.
متن کاملDifferentiation of rabbit sperm antigens from those of seminal plasma.
two glycoprotein sperm-specific antigens of testicular origin and twelve seminal plasma antigens which coated the spermatozoa during passage through the reproductive tract. Two of the sperm-coating antigens originated in the testis, two in the epididymis and eight above the level of the vas deferens. Relationships between sperm-coating antigens and capacitation, and sperm-coating antigens and p...
