Influence of spawning procedure on gametes fertilization success in Salminus hilarii Valenciennes, 1850 (Teleostei: Characidae): Implications for the conservation of this species
(Sociedade Brasileira de Ictiologia, 2011)
Artificial reproduction and gamete fertilization were evaluated in Salminus hilarii wild and domesticated broodstocks. Wild and domesticated broodstocks were artificially induced to reproduction using a carp pituitary ...

Sertoli cell-mediated differentiation of bovine fetal mesenchymal stem cells into germ cell lineage using an in vitro co-culture system
(Elsevier Inc., 2019)
In vitro gamete derivation based on differentiation of germ cells (GC) from stem cells has emerged as a potential new strategy for the treatment of male infertility. This technology also has potential applications in animal ...
Assisted reproductive technology in neotropical deer: A model approach to preserving genetic diversity
(2021-07-01)
One of the most significant challenges in deer is the ability to maintain genetic diversity, avoiding inbreeding and sustaining population health and reproduction. Although our general knowledge of reproductive physiology ...

Participation of epididymal cysteine-rich secretory proteins in sperm egg fusion and their potential use for male fertility regulation
(Chinese Acad Sciences, 2007-07-03)
Rat protein DE is an androgen-dependent cysteine-rich secretory protein (CRISP) synthesized by proximal epididymal regions. DE, also known as CRISP-1, is localized on the equatorial segment of acrosome-reacted spermatozoa ...

Epididymal protein CRISP1 plays different roles during the fertilization process
(American Society of Andrology, 2011-11)
Rat epididymal CRISP1, the first described member of the evolutionarily conserved Cysteine-RIch Secretory Protein (CRISP) family, is expressed in the proximal regions of the epididymis and associates with the sperm during ...
