Testicular sperm aneuploidy in non-obstructive azoospermic patients

Comparison of the aneuploidy frequency in embryos derived from testicular sperm extraction in obstructive and non-obstructive azoospermic men.

BACKGROUND The use of ICSI has been a major breakthrough in the treatment of male infertility. Even azoospermic patients with focal spermatogenesis in the testis (not sufficient to spill over into the ejaculate) may benefit from the technique. Previous reports suggest a higher pregnancy rate after ICSI treatment in patients with obstructive azoospermia (OA) compared to their non-obstructive azo...

enzymatic digestion improves testicular sperm retrieval in non-obstructive azoospermic patients

background: in patients with non-obstructive azoospermia (noa), vital spermatozoa from the tissue is obtained from testes by enzymatic treatment besides the mechanical treatment. objective: to increase the sperm recovery success of testicular sperm extraction (tese), with enzymatic digestion if no sperm is obtained from testis tissue by mechanical method. materials and methods: tissue samples w...

Enzymatic digestion improves testicular sperm retrieval in non-obstructive azoospermic patients

BACKGROUND In patients with non-obstructive azoospermia (NOA), vital spermatozoa from the tissue is obtained from testes by enzymatic treatment besides the mechanical treatment. OBJECTIVE To increase the sperm recovery success of testicular sperm extraction (TESE), with enzymatic digestion if no sperm is obtained from testis tissue by mechanical method. MATERIALS AND METHODS Tissue samples ...

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...
