Sperm morphology, motility, and concentration in fertile and infertile men.
BACKGROUND Although semen analysis is routinely used to evaluate the male partner in infertile couples, sperm measurements that discriminate between fertile and infertile men are not well defined. METHODS We evaluated two semen specimens from each of the male partners in 765 infertile couples and 696 fertile couples at nine sites. The female partners in the infertile couples had normal result...
متن کاملTHE CORRELATION BETWEEN SPERM MORPHOLOGY AND MOTILITY IN FERTILE AND INFERTILE MEN
The swim-up procedure was used to collect a sperm fraction with improved motility and normal morphology from fertile and infertile semen samples. The untreated and swim-up fractions were analyzed with the Hamilton-Thorn Motility Analyser. Comparisons were made to see the effect of this sperm selection technique on sperm motility and morphology. They were then examined by transmission elect...
متن کاملComparison of zinc concentrations in blood and seminal plasma and the various sperm parameters between fertile and infertile men.
The aim of the study was to examine the relationships between concentrations of zinc in blood and seminal plasma and sperm quality among infertile and fertile men. One hundred seven male (infertile group) partners of couples who were undergoing investigation for infertility with no known cause for the infertility and 103 men (fertile group) whose wives were pregnant at the time of the study wer...
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 کاملP-227: Effect of Cigarette Smoking on Seminal TAC and MDA Levels in Fertile and Infertile Men
Background: Defective sperm function is now recognized as one of the most important causes of male infertility. Lipid peroxidation (LPO) is known to cause various impairments of sperm cells and may play a major role in the etiology of male infertility. Malondialdehyde (MDA) is one of the final products of lipid peroxidation in seminal plasma. Seminal plasma possesses a rich source of different ...
