A study was conducted to investigate the various glycerol concentrations on freezability of mithun semen. The present study was conducted in semen production laboratory, ICAR-NRC on Mithun, Medziphema, Nagaland, India. A total of 20 ejaculates were collected from apparently healthy mithun bulls (n=6) by trans-rectal massage method. These ejaculates were extended with tris–egg yolk-citrate-glyce...

the goal of this study was the evaluation of semen extender filtration on post-thawed buck sperm quality. a total 16 ejaculates were collected from four buck (4 ejaculates from each buck) twice a week. after semen collection and primary evaluation, collected semen samples were pooled and divided into two equal parts. each part was diluted with one of the following extenders: 1) non-filtered lec...

The purpose of the present study was to assess the effect of modified camel milk (MCAM) and skim cow milk (SCOM) on semen quality of INRA180 and Boujaâd ram breeds, stored at 15°C for up to 24 hours. Semen samples were collected from eleven mature rams (6 from INRA180 and 5 from Boujaâd rams) and extended in SCOM vs MCAM, to reach a final concentration of 0.8×109 spermatozoa/mL, and stored at 1...

The current study was performed to test the of quality as well as the DNA integrity of preserved liquid and frozen buffalo spermatozoa due to addition of different concentrations of glutathione (0.50, 1.00, 2.00 and 3.00 mM). Liquid semen was preserved for 120 hour with or without addition of glutathione and examined for progressive motility, viability, plasma and acrosomal membranes integrity ...

OBJECTIVE To explore the associations between semen characteristics and subsequent risk of testicular cancer. DESIGN Cohort study. PARTICIPANTS 32 442 men who had a semen analysis done at the Sperm Analysis Laboratory in Copenhagen during 1963-95. MAIN OUTCOME MEASURE Standardised incidence ratios of testicular cancer compared with total population of Danish men. RESULTS Men in couples ...

STUDY QUESTION Is there an association between alcohol intake and semen quality and serum reproductive hormones among healthy men from the USA and Europe? SUMMARY ANSWER Moderate alcohol intake is not adversely associated with semen quality in healthy men, whereas it was associated with higher serum testosterone levels. WHAT IS KNOWN ALREADY High alcohol intake has been associated with a wi...

The present study investigated the existing relationship between computer assisted semen motility parameters and gametes motility duration, known to express semen quality and fertilizing capacity in fish. The objective was particularly to identify computer aided semen analysis (CASA) parameters that could be used as potential fertility predictors. Semen samples were collected from the beginning...

The aim of the present study was to measure lanthanum (La), cerium (Ce), europium (Eu), and gadolinium (Gd) concentrations in human semen and correlate the results with sperm quality. The median semen content of La was 19.5 µg kg(-1) dry weight (dw) (range 2.27-269), of Ce was 41.9 µg kg(-1) dw (range 4.52 to 167), of Eu was 0.68 µg kg(-1) dw (range 0.06-1.95), of Gd was 3.19 µg kg(-1) dw (rang...

The purpose of this study was to evaluate the probable effects of leptin addition in different levels to the semen extender on sperm quality (motility and motility parameters, viability, sperm membrane integrity, and DNA damage). Semen specimens were evaluated immediately after leptin addition, equilibration time and after thawing the frozen semen. Five healthy buffalo bulls (5 ejaculates from ...

Bulls vary greatly in semen quality, both among bulls and among ejaculates within a bull. Therefore, semen is evaluated routinely using those characteristics that are known to affect fertility. These include general appearance of the semen, volume of the ejaculate, concentration of sperm, motility, metabolic activity, percent live/dead and morphological abnormalities. The minimum levels for a s...
