morphological diversity of sperm: a mini review

Morphological diversity of sperm: A mini review

Sperms are highly specialized cells for delivering DNA from male to the ovum. Incredibly, wide degree of diversity in sperm morphology in their basic structures i.e. head, middle piece and tail is found across species. Differences in terms of overall size of the sperm, shape and number of sperm produced are also incredible. One of the key for this variations or diversity in sperm may be associa...

the profile of human sperm proteome; a mini-review

new advances in mass spectrometry-based proteomics technology are having amajor impact on our understanding of how human spermatozoa acquire their capacity for fertilization. a complete analysis of the proteins found in the human spermatozoa is essential for understanding the events leading up to, and including, fertilization and early embryo development. in this short review, we have collected...

The Profile of Human Sperm Proteome; A Mini-review

New advances in mass spectrometry-based proteomics technology are having a major impact on our understanding of how human spermatozoa acquire their capacity for fertilization. A complete analysis of the proteins found in the human spermatozoa is essential for understanding the events leading up to, and including, fertilization and early embryo development. In this short review, we have collecte...

Antioxidants for elevated sperm DNA fragmentation: a mini review

MINI REVIEW Sexually antagonistic coevolution in insects is associated with only limited morphological diversity

Traits specialized for male–female interactions have long been known to commonly show rapid and divergent evolution, and thus to differ even among closely related species (West-Eberhard, 1983; Eberhard, 1985; Andersson, 1994). Traits such as courtship songs and male genitalia are often key traits for distinguishing species (e.g. Mayr, 1963) (Fig. 1). This rapid divergence has enabled taxonomist...

MINI REVIEW Glycobiology of sperm–egg interactions in deuterostomes

The process of fertilization begins when sperm contact the outermost egg investment and ends with fusion of the two haploid pronuclei in the egg cytoplasm. Many steps in fertilization involve carbohydrate-based molecular recognition between sperm and egg. Although there is conservation of gamete recognition molecules within vertebrates, their homologues have not yet been discovered in echinoder...
