In this review, we consider sperm competition and monogamy as two ends of the selective spectrum, and discuss its effect on sperm structure and function. We address the issue of a lack of sperm competition by comparing sperm traits of essentially monogamous species—their largely degenerative sperm...
Structure and control of a cell-cell adhesion complex associated with spermiation in rat seminiferous epithelium. J Androl 2001 . 22: 1030 – 1052 .Chapin RE, Wine RN, Harris MW, Borchers CH and Haseman JK (2001) Structure and control of a cell -cell adhesion complex associated with ...
Obviously, the direct effect of PVP on sperm structure and function is still controversial. We have applied our submicroscopical method of sperm evaluation (=-=Baccetti et al., 1995-=-, 1997; Strehler et al., 1995; Piomboni et al., 1996) to this problem. Materials and methods The ...
makes it possible to systematically explain observed variability in coda structure. While the communicative function of many codas remains an open question, our results show that the sperm whale communication system is, in principle, capable of representing a large space of possible meanings, using si...

The mammalian spermatozoon constitutes one of the most complex and specialized cell types found in organisms. The structural heterogeneity found in the sperm head suggests an association between its inner composition, shape and specificity of function. However, little is known about the extent of the...
parameters can provide a comprehensive understanding of the patient’s semen status, sperm motility, sperm morphology, defect degree of genetic material in sperm head nucleus, and accessory gonadal secretion function, which has important guiding significance for the diagnosis and treatment of infertility....
Recent studies have demonstrated the significance of sperm RNA function as a transporter of important information directing the course of life. To determine the message contained in sperm RNA, it is necessary to optimize transcriptomic research tools. Th
