Autor: Cristina Soriano-Úbeda, Jon Romero-Aguirregomezcorta, Carmen Matás, Pablo E. Visconti, Francisco A. García-Vázquez

Publikováno v: Journal of Animal Science and Biotechnology, Vol 10, Iss 1, Pp 1-15 (2019)

Abstract Background The in vivo concentration of bicarbonate (HCO3 −), one of the essential sperm capacitating effectors, varies greatly in the different environments sperm go through from cauda epididymis to the fertilisation site. On the contrary

Alpha-Linolenic Acid: It Contribute Regulation of Fertilization Capacity and Subsequent Development by Promoting of Cumulus Expansion during Maturation

Autor: Ji-Eun Lee, Yong Hwangbo, Choon-Keun Park, Boo-Keun Yang, Hee-Tae Cheong

Publikováno v: Development & Reproduction

The objective of this study was to evaluate the effects of alpha-linolenic acid (ALA) during in vitro maturation (IVM) on cumulus expansion, nuclear maturation, fertilization capacity and subsequent development in porcine oocytes. The oocytes were in

Achieving monospermy or preventing polyspermy?

Autor: Dale B

Publikováno v: Research and Reports in Biology, Vol 2016, Iss Issue 1, Pp 47-57 (2016)

Brian Dale Centre for Assisted Fertilization, Naples, Italy Abstract: Images of sea urchin oocytes with hundreds of spermatozoa attached to their surface have fascinated scientists for over a century and led to the idea that oocytes have evolved mech

The main cause of low efficiency of in vitro produced porcine embryos is the high polyspermic penetration rates at fertilization, which is aggravated in low quality oocytes. Experiment 1 evaluated the embryo development in high and low quality oocyte
