The present experiment was conducted at ICAR-National Dairy Research Institute, Karnal, Haryana. Eighteenmale crossbred bucks (Alpine × Beetal) (average 103.94±2.87 days old) were divided into three groups withsix animals in each group, viz. T1 , T2 and T3 . Animals of group fed different green fodder concentratemixture to meet their daily nutrient requirement. according except 20% replacement ...

or Hets and WT (Table 1) for testicular weights, a measure of total sperm production. However, in analyses of a minimum of 200 sperm per animal, gross motility (80% reduced) and progressive motility (91% reduced) were significantly (P < 0.001; Table 1) impaired in null sperm, compared to WT. The Het sperm showed 35% and 32% decrease (P < 0.001) in gross and progressive motility (P < 0.001), com...

BACKGROUND The most common chromosomal abnormality due to non-obstructive azoospermia (NOA) is Klinefelter syndrome (KS) which occurs in 1-1.72 out of 500-1000 male infants. The probability of retrieving sperm as the outcome could be asymmetrically different between patients with and without KS, therefore logistic regression analysis is not a well-qualified test for this type of data. This stud...

Background: Acyclovir is asynthetic purin nucleoside analog,which has been reported to be very effective against the treatment of herpes simplex and varicella zoster infections. Acyclovir is known to be toxic to gonads, but available literature fails to provide the indepth analyses of damage.The aim of the present study was to evaluate the effect of Acyclovir on DNA damage and nuclear maturatio...
