Since all domestic turkeys are produced through artificial insemination, a measurable sperm characteristic that would be predictive of fertility would allow for the culling of poor males, resulting in improved reproductive efficiency. The sperm mobility test (SMT), which quantifies sperm penetration into an Accudenz solution, has been shown to correlate highly with fertilization potential of in...

background: one of the main laboratory tests for evaluation of infertility is semen analysis (sa). however additional tests may be suggested for further diagnosis of male fertility potentials. the seminal fluid contains sperms non-sperm cells and various types of lipids and glucose. objective: the objective of this cross-sectional study was to correlate the sperm parameters with concentrations ...

conclusions our results show that oxidative stress could play an important role in male infertility as well as in sperm motility and sperm morphology. patients and methods this case control study was conducted using 35 men with idiopathic infertility and 34 men with proven fertility. seminal plasma tac and mda were measured by ferric reducing ability of plasma (frap) and thiobarbituric acid (tb...

Background: Vitamin E is believed to be the primary component of the antioxidant system in spermatozoa. There is a relationship between activity of these antioxidant and function of sperm. Vitamins E and C which are belong to non-enzymatic antioxidant are used as a supplemented drug to improve sperm quality and male fertility. The present study was carried out to investigate the positive effect...

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...

In order to determine iron and lead content of seminal plasma in water buffalo and to study their associations with the semen characteristics, 54 semen samples were collected from 10 buffalo bulls. The semen characteristics were evaluated; its iron and lead content were estimated by atomic absorption spectrophotometer. The iron and lead content of the seminal plasma (Mean ± SEM) was recorde...

conclusions our findings indicated that oxidative stress could play an essential role in male infertility caused by varicocele and may impair spermatogenesis leading to infertility. objectives in the current study, we aimed to assess the tac (total antioxidant capacity) and mda (malondialdehyde) as stress oxidative markers in infertile men with varicocele and fertile men, and moreover, their co...

Background: It is shown that hypertension may affect androgens. The role of blood pressure on sperm parameters is matter of debate. The main goal was to evaluate the probable association between systolic and diastolic blood pressure and sperm parameters. Materials and Methods: Semen Sample of men (aged: 27- 45 years old) from 40 infertile cases who attended at Yazd research and clinical center ...

The present study was conducted to compare sperm motion characteristics of adult Malpura and Bharat Merino rams by the computer-aided sperm analysis (CASA) technique. Malpura is a hardy native sheep breed of the semi-arid tropical environment and Bharat Merino is a crossbred evolved in the same environment by crossing native sheep with exotic rams. Semen was collected from 8 donor rams of each ...
