background: sperm preparation is a fundamental step in art and attempt for developing new methods to be continued. objective: to evaluate the efficacy of upstream method for separation of human spermatozoa and its effects on sperm parameters including: motility morphology and concentration. materials and methods: semen samples from 17 men who referred to infertility clinic for evaluating their ...

The semen analysis is the main diagnostic tool for evaluating the male fertility potential. The standard semen analysis includes evaluation of the sperm concentration, motility, and their morphology. The most important question is whether the results from semen analysis may be accurate markers for male fertility. Therefore, we retrospectively studied sperm quality among men attending the infert...

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...

Objective To investigate effects of cryopreservation on changes of the ultrastructure of human testicular sperm and evaluate the efficacy of cryopreserving testicular tissue as a source of sperm for assisted reproduction. Methods Testicular biopsy tissues were obtained from infertile patients (n=12) with obstructive azoospermia and cryopreserved. Testicular sperm motility was observed after in ...

BACKGROUND The present study aimed to analyze the prognostic value of sperm morphology , total motile sperm count (TMSC) and the number of motile sperm inseminated (NMSI) on the outcome of intrauterine insemination (IUI). MATERIALS AND METHODS This cross sectional study was carried out 445 women undergoing 820 IUI cycles. All of the patients underwent controlled ovarian hyper stimulation with...

Objective: To compare the effectiveness of carbon dioxide and carbon dioxide-free incubation system in extracting motile, morphologically normal and chromatin intact sperm populations from the individual semen samples. Materials and Methods: Semen samples were obtained from normozoospermic men presenting for infertility evaluation. Individual samples were divided into two equal aliquots for spe...
