Abstract:
Background: Infertility is the inability of a sexually active, non-contraceptive couple to achieve spontaneous pregnancy in one year. It is estimated to affect worldwide up to 15% of couples; overall, a male infertility factor has been found in at least 40% of infertile couples. Several studies have shown that infertile men have a higher incidence and prevalence of cancer, chronic non-malignant morbidities, endocrinological and autoimmune disorders, and overall a higher mortality risk compared to fertile age-matched men. Various hypotheses have been considered to explain the factors underlying

Abstract:
Includes bibliographical references<br>This study aims to address the lack of data on the link between BMI and infertility in the South African population by describing the prevalence of male overweight and obesity in a group of men undergoing infertility investigation, as well as assessing any semen analysis abnormalities in these groups. It also aims to describe how well men can predict their BMI category and determine whether weight loss would be an acceptable part of infertility management in overweight or obese male partners. Beliefs surrounding healthy weight and fertility will also be a

Abstract:
During the last half of the 20<sup>th</sup> century, the world pork industry has achieved astonishing developments in pig breeding. Now swine farms are larger, ownership more concentrated, and farms have become more industrialized. Artificial insemination (AI) plays an important role in animal breeding increasing utilization of genetically superior sires. Currently boars selected for commercial use as AI sires are evaluated on grow-finish performance and carcass characteristics. The objectives of this study were to (A) estimate genetic correlations between production and semen traits in the bo

Abstract:
This dissertation focuses on the effect of breeding on the myocardium of stallions using cardiac troponin I (cTnI) as the preferred blood biomarker for detection of myocardial cell injury. Haematological, echocardiographic and heart rate (HR) parameters are also reported. Fourteen clinically healthy phantom-trained stallions were assessed. Cardiac troponin I concentration was determined pre-semen collection and at 4, 6, 12 and 24 hours following semen collection. Predictors that were measured included mean HR during each stage of semen collection, maximum HR, area under the curve for HR and fr
