Gamete quality in fish: evaluation parameters and determining factors
(CAMBRIDGE UNIV PRESS, 2015)
Segregation for Sexual Seed Production in Paspalum as Directed by Male Gametes of Apomictic Triploid Plants
(Oxford University Press, 2007-09)
Background and Aims: Gametophytic apomixis is regularly associated with polyploidy. It has been hypothesized that apomixis is not present in diploid plants because of a pleiotropic lethal effect associated with monoploid ...

(Universidad de Costa Rica, 2021)
Photoperiod in aquaculture of the sea urchin Arbacia dufresnii (Echinodermata: Echinoidea): Effects on gamete production and maturity
(Universidad de Costa Rica, 2021-03)
Introduction: Photoperiod is, together with temperature and food availability, one of the main stimuli in the regulation of gametogenesis in a wide variety of species. Objective: To evaluate the effect of photoperiod on ...
The effects of stressful broodstock handling on hormonal profiles and reproductive performance of rhamdia quelen (Quoy & Gaimard) females
(2008-12-16)
A stressful environment induces cortisol that might affect fish breeding and reproduction. In the present work, which aimed to mimic aquacultural conditions of the jundia (Rhamdia quelen) hatcheries in southern South ...

Equine chorionic gonadotropin increases estradiol levels in the bovine oviduct and drives the transcription of genes related to fertilization in superstimulated cows
(Wiley-Blackwell, 2019-07-29)
In the bovine oviduct, estradiol (E2) stimulates secretion and cell proliferation, whereas progesterone (P4) suppresses them. In this study, we have evaluated the effect of two superstimulatory protocols (follicle-stimulating ...
Epithelial and neural cadherin expression in the mammalain reproductive tract and gametes and their participation in fertilization-related events
(Academic Press Inc Elsevier Science, 2015-05)
Mammalian fertilization involves a series of well-orchestrated cell-cell interaction steps between gametes, as well as among spermatozoa and somatic cells of both the male and female reproductive tracts. Cadherins are ...
