This study investigated the effect of exposure to zearalenone (ZEN) and its metabolites on the characteristics of epididymal spermatozoa, testicular and epididymal biometry and histology, and the concentration of testosterone in blood plasma in male wild boars. The study was performed during more than one year on 18 clinically healthy male wild boars with initial and final body weight, of 39 ± 4 kg and 59 ± 3 kg, respectively. The animals were divided into two experimental groups (group I and group II) and one control group (group C) comprising 6 boars per group. Read More

l-carnitine has a documented role as a cofactor in cellular energy metabolism and fatty acid beta-oxidation pathways and it has also been considered to function in reproductive biology. We investigated whether decreasing concentrations of L-carnitine using an inhibitor of its biosynthesis, mildronate (3-(2,2,2-trimethylhydrazinium)-propionate), would influence the sexual behavior or sperm quality in male rats. Mildronate treatment induced a significant decrease in carnitine concentration and an increase in gamma-butyrobetaine (GBB) concentration in both plasma and testes extracts. Read More

The role of FSH for Sertoli cell establishment and sperm production in the boar is not definitely known. In order to elucidate its function FSH was substituted postnatally in male pigs and the resulting effects on testicular histological traits and sperm production capacity were investigated when the boars had reached maturity. Six male piglets received pFSH from 18 to 48 days postnatally. Read More

The objective was to determine the effects of immunization against gonadotropin-releasing hormone on reproductive characteristics in boars. A total of 72 boars were used in a randomized design with three treatments: single immunization (SI) (10 weeks of age) or double immunization (DI) (10 and 15 weeks of age) with Improvest® and intact controls (no Improvest®; CNT) (n=24/group). At 10, 15, 20, 25 and 40 weeks of age, blood was collected and serum harvested to evaluate testosterone concentrations. Read More
