Comparison of Sperm Parameters Between Fertile and Subfertile Couples
Purpose: In each society approximately 15% of couples suffer from fertility disorders and half of these are up to male factors. The aim of this study was to design and perform a prospective study to analyze and compare sperm parameters of feriite and sub fertile couples, in order to determine the minimum values required for fertility in Isfahan. Materials and Methods: 20o semen samples from pa...
متن کاملUltrastructural Morphology of Sperm from Human Globozoospermia
Globozoospermia is a rare disorder characterized by the presence of sperm with round head, lacking acrosome. Coiling tail around the nucleus has been reported since early human studies, but no specific significance has conferred it. By contrast, studies on animal models suggest that coiling tail around the nucleus could represent a crucial step of defective spermatogenesis, resulting in round-h...
متن کاملCorrelation between Sperm Parameters and Sperm DNA Fragmentation in Fertile and Infertile Cigarette Smoking Patients
The present study to investigate that the correlation between sperm parameters and sperm DNA fragmentation in fertile and infertile cigarette smoking patient. Forty men undergoing infertility evaluation were divided into four groups according their smoking ability (A: 2 days ( n=10), B: 4 days ( n=10), C: 8 days ( n=10), D: 15 days ( n=10)) sperm parameters ( sperm concentration, pH, Viscosity,...
متن کاملCorrelation between sperm parameters and sperm DNA fragmentation in fertile and infertile men
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...
متن کاملReliability of the comet assay in cryopreserved human sperm.
BACKGROUND Although the comet assay has potential value for measuring DNA damage in large epidemiological human sperm studies, it is impractical to perform the assay daily on fresh semen samples. Therefore, before its use in epidemiological studies, the reliability of the comet assay in measuring DNA damage in cryopreserved sperm should be compared with that in fresh human sperm. METHODS Seme...
