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 examination of quality of the sperm ejaculate is one of the most important steps in artificial fertilization procedure. The main aim of semen storage centres is to characterise the best semen quality for fertilization. Reliable information about sperm motility is also one the most important parameters for in vitro laboratory procedures. There exist very expensive automated methods for semen...

Black Bengal goat is the heritage and one of the potential genetic resources of Bangladesh. Genetic and phenotypic parameters for semen characteristics and their relationships with scrotal circumference in Black Bengal bucks were estimated in this experiment. Genetic parameters were estimated by residual maximum likelihood procedure, fitting an animal model ignoring maternal genetic or permanen...

The Zn and Pb concentration was determined in 45 samples of bull semen from three Artificial Insemination Stations (A,B,C) differing in degree of environmental pollution. Bull semen was diluted with Biociphos-Plus to such an extent as to obtain 16 million sperm cells in an insemination dose. The research aimed at assessing the correlation between zinc, lead and other parameters influencing the ...

Sixty semen ejaculates from 10 mature bulls, 5 each of Jafarabadi and Mehsana breed, were studied for sperm motility and velocity parameters of fresh and frozen-thawed spermatozoa using computer assisted sperm analyzer (CASA). The mean values of motile and progressively motile spermatozoa observed in fresh semen of Jafarabadi and Mehsana bulls (79.77±1.62 and 61.80±1.85, and 78.90±1.22 and 61.3...

Semen hyperviscosity (SHV) is one of the factors involved in deficiency in sperm function. This research aimed to evaluate seminal plasma total antioxidant capacity (TAC) and malondialdehyde (MDA) levels in infertile patients with hyperviscous and non-hyperviscous semen samples to understand whether hyperviscous semen is associated with oxidative damage in infertile subjects. In this cross sect...

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...

introduction: different methods have been used to evaluate the beneficial effect of varicocelectomy; these include semen parameters and pregnancy rate. due to high biological variability of semen parameters, sperm functional test has been considered an efficient end point in assessment of fertility. therefore, the aim of this study was to evaluate the effect of varicocelectomy on semen paramete...

Qualitative parameters of piapara semen (Leporinus elongatus) were evaluated before and after hormonal induction with carp pituitary extract at 2.5 mg.kg(-1) of live weight. The progressive motility, the spermatic vigor and the lifetime of the spermatozoa were higher before the hormonal induction (P > 0.05). The percentage of normal spermatozoa and spermatozoa with secondary pathologies did not...
