Detection of Partial AZFc Microdeletions in Azoospermic Infertile Men Is Not Informative of MicroTESE Outcome
Objective microdeletions of Yq chromosome are the most frequent molecular genetics etiology for the male infertility which usually spans AZFa (azoo spermia factor a), AZFb and AZFc regions. Microdeletions are mostly seen in AZFc region and usually cover genes actively involved in spermatogenesis. Partial AZFc microdeletion may also happen with various spans namely gr/gr, b2/b3 and b1/b3. It is ...

Dear Editor, Trichomonas vaginalis (T. vaginalis), a flagellated protozoan parasite emerged as one of the most common nonviral sexually transmitted infections worldwide, often inhabits the vagina, urethra, prostate, and epididymis.1 It has been estimated that there are more than 170 million new cases of T. vaginalis infections per year worldwide. However, current knowledge of T. vaginalis and t...
متن کاملSperm retrieval techniques in azoospermic patients: PESA, MESA, TESA, TESE and MICROTESE Técnicas de recuperação de espermatozoides em pacientes azoospérmicos: PESA, MESA, TESA, TESE e MICROTESE
Received on: April 28, 2009 – Accepted on: Oct 15, 2009 aBstRact Azoospermia is defined as the absence of mature spermatozoa in semen analysis after centrifugation. The causes of azoospermia may be related to spermatogenesis defects and classified as nonobstructive azoospermia, or to the obstruction of the efferent ducts of the genital tract and classified as obstructive azoospermia. Before the...
متن کاملP-3: Complete Reproductive Hormonal Study in Nonobstructive Azoospermic (NOA) Patients for Determining Reliable Markers of The Presence of Spermatozoa in Their Biopsies
Background: Various hormone tests of the presence of spermatozoa on testicular sperm extraction (TESE) in azoospermic men have been investigated. Because of its clinical importance, we conducted this study to evaluate complete reproductive serum hormone levels in nonobstructive azoospermic (NOA) patients for determining markers which can predict the spermatogenesis. Materials and Methods: Seven...
متن کاملIn vitro differentiation of germ cells from nonobstructive azoospermic patients using three-dimensional culture in a collagen gel matrix.
OBJECTIVE To assess the effectiveness of the three-dimensional culture of spermatogenic cells in a collagen gel matrix from nonobstructive azoospermic patients and examine the relation between the success rate of in vitro spermatogenesis and serum FSH level as a diagnostic prediction. DESIGN Prospective study using radioimmunoassay, immunocytochemistry, and flow cytometry with primary culture...
