Comparison of Intracytoplasmic Sperm Injection Outcomes between Oligozoospermic, Obstructive Azoospermic and Non-Obstructive Azoospermic Patients
BACKGROUND To determine the differences in sperm quality and results of intracytoplasmic sperm injection (ICSI) cycles between three groups of male factor infertile couples: oligozoospermic, obstructive azoospermic and non-obstructive azoospermic. MATERIALS AND METHODS In this prospective cohort study, 628 male factor infertile couples who underwent ICSI cycles from April 2004 to March 2006 w...
متن کاملY chromosome azoospermia factor region microdeletions and transmission characteristics in azoospermic and severe oligozoospermic patients.
Spermatogenesis is an essential reproductive process that is regulated by many Y chromosome specific genes. Most of these genes are located in a specific region known as the azoospermia factor region (AZF) in the long arm of the human Y chromosome. AZF microdeletions are recognized as the most frequent structural chromosomal abnormalities and are the major cause of male infertility. Assisted re...
متن کاملPrevalence of Y chromosome deletions in a Brazilian population of nonobstructive azoospermic and severely oligozoospermic men.
We determined the prevalence of Y chromosome deletions in a population of 60 Brazilian nonobstructive azoospermic and severely oligozoospermic men. PCR-based screening of microdeletions was performed on lymphocyte DNA for the presence of 14 sequence-tagged sites (STS) located in the azoospermic factor (AZF) on the Yq chromosome. All STS were amplified efficiently in samples from 12 fertile men ...
متن کاملClinical use of testicular fine needle aspiration cytology in oligozoospermic and azoospermic dogs.
Clinical investigation of canine testicular function is complicated by the difficulty in the evaluation of seminiferous tubules. Until recently, testicular biopsy was the only diagnostic option for dogs with persistent oligo/azoospermia. In human andrology, testicular fine needle aspiration (TFNA) is currently considered a useful method in the evaluation of azoospermia and severe oligozoospermi...
متن کاملAndrogen receptor gene GGN and CAG polymorphisms among severely oligozoospermic and azoospermic Swedish men.
BACKGROUND We investigated the androgen receptor gene GGN polymorphism and its relation to male infertility and receptor function. METHODS Ninety-nine infertile patients with sperm counts < or = 5 x 10(6)/ml were screened for karyotypic abnormalities and Y-chromosome microdeletions. The GGN and CAG repeats were sequenced in those without genetic abnormalities and in 223 controls. RESULTS Fi...
