The in vitro production of porcine embryos has presented numerous challenges to
researchers over the past four decades. Some of the problems encountered were specific to …

Lutein cells produce progestins that support pregnancy. Steroidogenesis requires
coordination of the anabolic and catabolic pathways of lipid metabolism. Peroxisome …

The present study examined the penetrability of pig oocytes by frozen-thawed ejaculated
boar spermatozoa, prepared by the pellet method, coincubated in a modified Tris-buffered …

Porcine in vitro production (IVP) systems, including in vitro maturation (IVM) and in vitro
fertilization (IVF) of oocytes and their subsequent in vitro culture (IVC), have been modified …

The influence of prolonged storage of boar epididymides on post-thaw sperm motility, and in
vitro fertilization was evaluated. Twenty pairs of epididymides were obtained from Large …

The objective of the present study was to evaluate the ability of rosemary to protect
epididymal boar spermatozoa from freeze-thaw damage. Testis from eight boars were …

Porcine cumulus-oocyte complexes were cultured in BSA-free Whitten's medium or modified
Medium 199, each supplemented with porcine follicular fluid (PFF) and hormonal …

Assisted reproduction technology (ART) protocols are used in livestock for the improvement
and preservation of their genetics and to enhance reproductive efficiency. In the case of …

The objective of this study was to compare the in vitro fertilizing capacity of porcine
spermatozoa from fresh and frozen-thawed semen and frozen-thawed epididymal …

A method of cryopreservation was developed for sperm salvaged from the cauda epididymis
and vas deferens of domestic dog testes. Four modifications of the glycerol concentration of …
