OBJECTIVE To study the effect of cigarette smoking on seminal fluid parameters, namely; volume, sperm concentration, and motility, as well as morphology, leukocyte infiltration, among males complaining of infertility. METHODS Between August 2010 and July 2011, seminal fluid analysis was done for 1438 males who are partners of couples who visited the infertility clinic at Prince Rashid Ben Al ...
Strategies to increase the population and productivity of beef cattle can be implemented through reproductive management, such as artificial insemination (AI) using frozen semen. This study aims evaluate characteristics semen Limousin bulls different ages, which still used for programs up 12 years age. ages 3, 8, produced in 2021 at Artificial Insemination Center Singosari, East Java Province, ...
population mean heterozygosity (i.e. 12 data points). Both analyses were statistically significant, indicating that populations with low heterozygosity have relatively abnormal sperm. Two alternatives to inbreeding depression are consistent with this result: a third, unknown factor causes some populations to have low heterozygosity and relatively abnormal sperm; for instance, environmental hete...
BACKGROUND In this study we aimed to evaluate the impact of chronic exposure to the Gly-phosate (GP) on rat's testicular tissue and sperm parameters. OBJECTIVE Testicular tissue, morphology of sperms and testosterone level in serum of mature male rats were analyzed. MATERIALS AND METHODS Animals were divided into two test and control-sham groups. The test group was subdivided into 4 groups ...
Male genital tract obstructions may result from infections, previous inguinal and scrotal surgery (vasectomy) and congenital bilateral absence of the vas deferens (CBAVD). Microsurgery can sometimes be successful in treating the obstruction. In other cases and in cases of failed surgical intervention, the patient can be treated by microsurgical or percutaneous epididymal sperm aspiration (MESA,...
We performed immunofluorescent analysis of DNA hydroxymethylation and methylation in human testicular spermatogenic cells from azoospermic patients and ejaculated spermatozoa from sperm donors and patients from infertile couples. In contrast to methylation which was present throughout spermatogenesis, hydroxymethylation was either high or almost undetectable in both spermatogenic cells and ejac...
Abstract Study question Is it possible to classify sperm morphology as normal or abnormal based on their kinetic characteristics? Summary answer Using different classifiers, was found that balanced dataset the classification scores of individual can be optimized during motility just before ICSI What is known already Sperm selection plays a crucial role ICSI. This by embryologists accompanied tw...
