This review explores the relationship between sperm chromosomal constitution and morphology. With the advent of techniques for obtaining information on the chromosome complements of spermatozoa, this relationship has been studied in fertile men and in men with a high frequency of chromosomal abnormalities. Using human sperm karyotype analysis, no relationship between sperm chromosome abnormalit...
BACKGROUND Y chromosomal microdeletion is an important genetic disorder, which may arise due to intrachromosomal recombination between homologous sequences in the male specific region of the human Y chromosome. It is frequently associated with the quantitative reduction of sperm. The screening for Y chromosomal microdeletions has a great clinical value. OBJECTIVE To develop a sequence tagged ...
BACKGROUND TEX101 is a cell membrane protein exclusively expressed by testicular germ cells and shed into seminal plasma. We previously verified human TEX101 as a biomarker for the differential diagnosis of azoospermia, and developed a first-of-its-kind TEX101 ELISA. To demonstrate the clinical utility of TEX101, in this work we aimed at evaluating ELISA performance in a large population of fer...
abstract background: infertility is a major psychosocial crisis as well as being a medical problem. the factors that predict psychosocial consequences of infertility may vary in different gender and different infertile populations. objective: the primary purpose of this study was to investigate whether turkish infertile couples had higher levels of depression and anxiety when compared to non-in...
background: heat shock protein a2 (hspa2) is correlated with sperm maturity and function. therefore, dysfunctional expression of this gene results in abnormal spermatogenesis. on the other hand, dna damage in spermatozoa is considered to be an important cause of male infertility, and the presence of sperm with dna fragmentation and chromatin abnormalities in human ejaculates is well documented,...
