Enhancement of mouse sperm motility by trophinin-binding peptide
Reproductive Biology and Endocrinology, 2012 Background Trophinin is an intrinsic membrane protein that forms a complex in the cytoplasm with bystin and tastin, linking it microtubule-associated motor dynein (ATPase) in some cell types. Previously, we found that human sperm tails contain trophinin,

Isolation and Characterization of a Rabbit Sperm Tail Protein [PDF]
Archives of Andrology, 1986 Rabbit sperm tails were obtained by a nitrogen cavitation procedure and separated by discontinuous sucrose gradient centrifugation. Proteins were extracted from sperm tails with 3[(3-cholamidopropyl)-dimethylammonio]-1-propane sulfonate (CHAPS) and separative disk electrophoresis and DEAE-trisacryl column chromatography. A protein with an estimated mol

Spermitin: a novel mitochondrial protein in Drosophila spermatids. [PDF]
PLoS ONE, 2014 Mitochondria, important energy centers in the cell, also control sperm cell morphogenesis. Drosophila spermatids have a remarkably large mitochondrial formation called the nebenkern.

Tales of the Tail and Sperm Head AchesChanging concepts on the prognostic significance of sperm pathologies affecting the head, neck and tail [PDF]
Asian Journal of Andrology, 2011 This article presents an update on the variable prognostic significance of different sperm pathologies in patients with severe male factor infertility due to morphology and motility disorders. Severe asthenozoospermia is one of the leading causes of male infertility as spermatozoa cannot reach the oocyte and/or penetrate normally.

The legacy of sperm banking: how fertility monitoring and disposal of sperm are linked with views of cancer treatment [PDF]
, 2011 Background: sperm banking is recommended for all men before cancer treatment, which carries a risk of long-term gonadal damage. However, relatively few men take up the offer.
