It has, however, become apparent that none of these procedures are sufficient for the determination of male fertility capacity. Owing to the lack of adequate methods to evaluate the fertility potential of a couple, the choice of ART method is made more or less blindly. A continuous search for...
Spermatazoa are the male gamete,meaning they are the cells that fuse with the egg in fertilization giving rise to the embrion and future baby.
remains unknown. We show that codas exhibit contextual and combinatorial structure. First, we report previously undescribed features of codas that are sensitive to the conversational context in which they occur, and systematically controlled and imitated across whales. We call these rubato and ornamentati...
In addition, sperm quality related miRs have also been analyzed in good and bad zebrafish breeders. All of these miRs (miR-122-5p, miR 141-3p and miR-200a-5p) were previously defined as molecular markers in human sperm11, and they are differentially present in normozoospermic when compare...
plants. CNGC are key players in chemotaxis of sperm from sea urchins (Bönigk et al.2009) and motility of Zebrafish (Fechner et al.2015) and control Ca2+entry in sperm. It would interesting to find which Ca2+channels play a role in sperm chemotaxis among plants, and if CNGCs are invo...

Once the sperm are transferred to the female tract in spermatophores, marked changes occur in the sheath; the satellite body disappears, dense material appears between the inner margins of the radial discs, and the inner sheath differentiates into two distinct portions, both of which have a para...
