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 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 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 کاملSperm pathology: a step beyond descriptive morphology. Origin, characterization and fertility potential of abnormal sperm phenotypes in infertile men.
Sperm pathology is presented as the discipline of characterizing structural and functional deficiencies in abnormal spermatozoa. This concept complements that of sperm morphology mainly concerned with the appearance of spermatozoa. These two notions collaborate in providing correlations of prognostic value with sperm fertilizing capacity, explaining the mechanisms of sperm inefficiency, suggest...
متن کاملThe effect of rhFSH on Sperm DNA Fragmentation and sperm parameters in Oligozoospermia Infertile Men
Background: One of the main causes of male infertility is the negative effects of oxidative stress. Follicle-stimulating hormone (FSH) plays an essential role in spermatogenesis, as well as in the maintenance of sperm DNA integrity. This study aimed to determine whether the recombinant human follicle-stimulating hormone (rhFSH) treatment of sperm parameters could positively affect sperm DNA and...
