The epididymis, cytoplasmic droplets and male fertility.
The potential of spermatozoa to become motile during post-testicular maturation, and the relationship between the cytoplasmic droplet and fertilizing capacity are reviewed. Post-testicular maturation of spermatozoa involves the autonomous induction of motility, which can occur in vivo in testes with occluded excurrent ducts and in vitro in testicular explants, and artefactual changes in morphol...
متن کاملCytoplasmic Male Sterility and Fertility Restoration
Cytoplasmic male sterility (CMS), a condition under which a plant is unable to produce functional pollen, is widespread among higher plants. CMS systems represent a valuable tool in the production of hybrid seed in self-pollinating crop species, including maize, rice, cotton, and a number of vegetable crops. Hybrids often exhibit heterosis, more commonly known as hybrid vigor, whereby hybrid pr...
متن کاملImpact of socio-sexual conditions on the epididymis and fertility in the male mouse.
The influence of previous sexual experience and subsequent differential housing on the epididymis and fertility index was studied for male Swiss albino cc mice. Among animals with previous sexual experience those having a high epididymal beta-glucuronidase activity showed a high fertility index and vice versa. The reproductive potential of animals without previous sexual experience was reduced ...
متن کاملMitochondrial DNA rearrangement associated with fertility restoration and cytoplasmic reversion to fertility in cytoplasmic male sterile Phaseolus vulgaris L.
Restoration of pollen fertility to cytoplasmic male sterile (CMS) Phaseolus vulgaris by a nuclear restorer gene provides a system for studying nuclear-cytoplasmic interactions. Introduction of a nuclear restorer gene to this CMS line of P. vulgaris (CMS-Sprite) results in a mitochondrial genome rearrangement similar to that observed upon spontaneous cytoplasmic reversion to fertility. Three spo...
متن کاملAn Epididymis-Specific Secretory Protein HongrES1 Critically Regulates Sperm Capacitation and Male Fertility
Mammalian sperm capacitation is an essential prerequisite to fertilizion. Although progress had been made in understanding the physiology and biochemistry of capacitation, little is known about the potential roles of epididymal proteins during this process. Here we report that HongrES1, a new member of the SERPIN (serine proteinase inhibitor) family exclusively expressed in the rat cauda epidid...
