Effect of insulin-like growth factor I on functional parameters of ram cooled-stored spermatozoa

Original language description

The study was aimed at examining the effects of IGF-I on ram sperm traits after hypothermic (4?C) storage. Sperm ejaculates from 3 Lacaune rams were diluted in Triladyl, pooled and divided into the groups of IGF-I doses added (0, 10, 100 or 200 ng/ml). Following 72 h of storage the sperm samples were stained for a plasma membrane integrity (peanut agglutinin, PNA-FITC), membrane stability (annexin V-FITC) and apoptosis (Yo-Pro-1) and analyzed under a fluorescent microscope. Sperm motility was determinedby CASA (at 0, 24 and 48h) and fertilizing ability (at 48h) - by an in vitro fertilization (IVF) test on bovine oocytes. IGF-I (100 and 200 ng/ml) decreased the portion of spermatozoa with disrupted plasma membrane integrity (15.9 and 16.5% resp. vs 28.3% in control, p< 0.05) and, given at all tested doses, reduced the rate of apoptotic sperm (6.2, 4.9 and 4.4% resp. vs 9.7% in control, p< 0.05). The proportion of spermatozoa with annexin V-labelled membrane changes was reduced by IGF-I
