Routine macroscopic and microscopic analyses of semen quality were accompanied by measurement of Se content and GSH\u2010Px activity in blood and semen. The Se concentration in blood plasma, seminal fluid and spermatozoa was measured by fluorometric method, the GSH\u2010Px activity by a method based on NADPH\u2010coupled reaction. A total of 155 ejaculates and 58 blood samples were investigated. The results of this study showed that there was no direct relationship between the Se content and GSH\u2010Px activity in blood plasma and semen, and semen quality of sexual matured boars. The mechanisms controlling Se content and GSH\u2010Px activity in blood and semen seem to be independent. The age of boars as a differentiating factor for Se content and GSH\u2010Px activity in blood and semen is possible. It is concluded that a determination of Se status and\/or GSH\u2010Px activity in organism before Se supplementation is indicated.<\/jats:p>","DOI":"10.1111\/j.1439-0531.2004.00514.x","type":"journal-article","created":{"date-parts":[[2004,9,13]],"date-time":"2004-09-13T13:13:26Z","timestamp":1095081206000},"page":"309-314","source":"Crossref","is-referenced-by-count":16,"title":["Selenium Status and GSH\u2010Px Activity in Semen and Blood of Boars at Different Ages Used for Artificial Insemination"],"prefix":"10.1111","volume":"39","author":[{"given":"B","family":"Lasota","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B","family":"B\u0142aszczyk","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B","family":"Seremak","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J","family":"Uda\u0142a","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2004,9,13]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1095\/biolreprod41.1.183"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1136\/vr.96.16.360"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1439-0396.1998.tb00519.x"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1095\/biolreprod23.5.1007"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2605.1988.tb01014.x"},{"key":"e_1_2_7_7_1","first-page":"A3","article-title":"The requirement for selenium and vitamin E in weaned pigs","author":"Bengtsson G","year":"1976","journal-title":"Proc.
