Maintaining a successful pig artificial insemination programme depends on a number of factors, including evaluation of semen characteristics. This study compared the efficacy of different extenders on the sperm motility of Kolbroek semen during short term storage at 4 °C and 25 °C. Semen was collected from Kolbroek boars using the gloved hand technique and transported to the laboratory for eval...

Background: Semen cryopreservation is the most important section of artificial insemination programs; it allows preservation of semen fertility for a long time. Materials and Methods: The aim of the present study was to detect the effect of in vitro supplementation of 4-hydroxy Tempo on fresh and frozen spermatozoa quality of buffalo bulls. Five healthy buffalo bulls (5 ejaculates from each bul...

A retrospective analysis of sixty one prospective donors who visited the cryobank in person from August 1999 to December 2001 was done. The study evaluated the acceptance rate of prospective semen donors and semen characteristics in order to assess the fertility potential of the supposedly normal population of young men. The outcome of the various screening processes--history taking, infection ...

AIM To assess whether exposure to computers harms the semen quality of healthy young men. METHODS A total of 178 subjects were recruited from two maternity and children healthcare centers in Shanghai, 91 with a history of exposure to computers (i.e., exposure for 20 h or more per week in the last 2 years) and 87 persons to act as control (no or little exposure to computers). Data on the histo...

BACKGROUND There is some controversy about the extent of changes in different sperm cell features in stored boar semen, especially regarding the potential role of the DNA fragmentation assay for assessment of sperm fertilizing ability. The aim of this study was to assess the effect of time of storage and the dynamic changes in sperm cell characteristics in normospermic boar semen stored in long...

Research has demonstrated that porcine circovirus type 2 (PCV2) can be shed into boar semen, raising the possibility that artificial insemination may be an important route by which disease associated with PCV2 is transmitted. The objective of this experiment was to determine the effect of vaccination against PCV2 on ejaculate characteristics and PCV2-specific antibody titers in serum of PCV2-po...

The present study aimed to verify the caprine semen characteristics during dry and rainy seasons in the Brazilian Northeast, and the influence of these seasons on cooled semen. Seminal volume, concentration, percentage of motile cells, vigor and spermatic morphology, as well as biochemical profile (fructose, citric acid, P, Ca 2+ , Mg, total proteins and phospholipase A2 activity) were analyzed...

BACKGROUND: To investigate the relationship of human semen parameters with season, age and smoking status. METHODS: The present study used data from subjects recruited into an ongoing cross-sectional study on the relationship between environmental agents and semen characteristics. Our population consisted of 306 patients who presented to the Vincent Memorial Andrology Laboratory of Massachusett...

OBJECTIVE To assess the association between Follicle-Stimulating Hormone (FSH) and semen parameters in order to evaluate whether the current laboratory reference for abnormal FSH levels should be readjusted. STUDY DESIGN Observational, cross-sectional study. PLACE AND DURATION OF STUDY Infertility Clinic of Gynecology Unit 1, Civil Hospital, Karachi, from May 2015 to April 2016. METHODOLO...
