background: it is established that sperm dna integrity is essential in fertilization and normal embryo and fetal development. routine semen analysis gives an approximate evaluation of the functional competence of spermatozoa, but does not always reflect the quality of sperm dna. therefore, the evaluation of sperm dna integrity, in addition to routine sperm parameters, could add further informat...

In this study, quantitive characteristics and chemical composition of in roach (Rutilus rutilus caspicus) sperm were investigated. Sperm traits included sperm movement duration, percentage of motile spermatozoa, sperm density, spermatocrit and sperm volume. Some seminal plasma characteristics (sodium, potassium, calcium, magnesium and chloride) were investigated. In addition, some metabolites o...

The present study evaluated the relationship between Bali bull (Bos javanicus) seminal plasma proteins and different semen quality parameters. Semen samples from 10 mature Bali bulls were evaluated for conventional semen parameters (general motility, viability, and normal morphology), sperm functionality (acrosome reaction, sperm penetration rate, sperm penetration index), sperm kinetics (compu...

objective: in sever oligospermia; one of the paths used for surgical sperm retrieval (ssr) is to extract sperm via a testicular biopsy. the aim of our study is to determine the reliable time interval between testicular biopsy and intracytoplasmic sperm injection (icsi) procedure in order to obtain optimumsperm parameters (count, motility and normal morphology). materials and methods: this cohor...

Background: Obesity is a leading preventable cause of death worldwide, with increasing prevalence in adults and children. Some studies have shown that increased body mass index is related to poor semen quality, decreased sperm concentration, decreased normal-motile sperm cells and increased DNA fragmentation index. Lipid peroxidation contributes to the damage of the sperm plasma membrane. Cinna...

Background: Optimal thawing rate is critical for quality and fertilizability of frozen -thawed spermatozoa. Kinetic parameters are the most important factors which are affected by thawing rate so, that have close relation between kinetic parameters and fertility of the spermatozoa. Tris - egg yolk have been widely used for cryopreservation of the buffalo and other species semen. According to ou...

Background: Adipose tissue is not only an energy storage tissue but also an important endocrine organ that secretes protein hormones. Among them, the production and secretion of adiponectin is inversely correlated to the severity of obesity. In adipose tissue, adiponectin production is transcriptionally regulated by peroxisome proliferator-activated receptor-γ (PPAR-γ). Obesity is a major healt...

Background: Phenol is an estrogenic and toxic compound and people are widely exposed to it, in different ways.  OBJECTIVES: The aim of this study was to determine  the  negative effects of phenol on the fertility of male mice, by investigating sperm parameters including viability, motility, fertility rates and daily sperm production (DSP). METHODS: A total of 106 adult NIH mice were divided int...

Koonjaenak S. 2006. Semen and Sperm Characteristics of Swamp Buffalo (Bubalus bubalis) Bulls for Artificial Insemination in Thailand, in Relation to Season. Doctoral thesis. ISSN 1652-6880, ISBN 91-576-7263-6 In this thesis work we tested the hypothesis that tropical climatic conditions affect the quality of fresh and frozen-thawed (FT) spermatozoa from swamp buffalo bulls used for artificial i...
