Major spliceosome defects cause male infertility and are associated with nonobstructive azoospermia in humans.
Processing of pre-mRNA into mRNA is an important regulatory mechanism in eukaryotes that is mediated by the spliceosome, a huge and dynamic ribonucleoprotein complex. Splicing defects are implicated in a spectrum of human disease, but the underlying mechanistic links remain largely unresolved. Using a genome-wide association approach, we have recently identified single nucleotide polymorphisms ...
متن کاملI-6: Azoospermia Factor in Male Infertility
Background The human Y chromosome is essential for human sex determination and male germ cell development and maintenance. In 1996, Vogt et al. identified three recurrently deleted regions in Yq11 termed the azoospermia factor (AZF). The AZF region is subdivided into three non-overlapping sub-regions called AZFa, AZFb and AZFc and microdeletion in these regions is the most important etiology of...
متن کاملMutations of Two Major Coagulation Factors Are Not Associated with Male Infertility.
BACKGROUND Thrombophilia-related mutations, such as coagulation factor V Leiden and factor II (G20210A), have been associated with female infertility due to spontaneous abortions during pregnancy. The possible role of mutations of these two factors in male infertility has not been studied to date. MATERIALS AND METHODS A total of 208 unrelated Greek men were investigated, including 108 infert...
متن کاملSurgical management of nonobstructive azoospermia
Nonobstructive azoospermia (NOA) is characterized by the complete absence of sperm in the ejaculate due to testicular failure. The evaluation and management of patients with NOA offer a challenge to the reproductive urologist. In the era of in vitro fertilization with intracytoplasmic sperm injection, surgical sperm extraction techniques can afford men with NOA biologic paternity. To provide a ...
