Patients with absolutely immotile spermatozoa and intracytoplasmic sperm injection.
The microinjection of completely immotile spermatozoa may impair the outcome of intracytoplasmic sperm injection (ICSI). Eleven couples underwent an initial ICSI cycle with 100% immotile freshly ejaculated spermatozoa. Two-pronuclear fertilization ensued in 18 of 145 (12.4%) successfully injected oocytes. None of these cycles resulted in a pregnancy. Nine couples underwent ICSI in subsequent cy...
متن کاملDifferent fertilization rates between immotile testicular spermatozoa and immotile ejaculated spermatozoa for ICSI in men with Kartagener's syndrome: case reports.
We report two cases of infertility treatment in couples where males suffered from Kartagener's syndrome (KS) and a total absence of motile sperm in the ejaculate. A total of three ICSI cycles was carried out. In all cycles, viable ejaculated or testicular spermatozoa were selected using the hypo-osmotic swelling (HOS) test. Case 1: In the first ICSI cycle total fertilization failure occurred af...
متن کاملBlastocyst transfer following intracytoplasmic injection of ejaculated, epididymal or testicular spermatozoa.
Recent studies indicate a strong paternal influence on embryo development and progression of the embryo to the blastocyst stage. The aim of this study was to compare, during extended culture, the in-vitro development of embryos resulting from intracytoplasmic sperm injection (ICSI) of ejaculated spermatozoa (group 1, n = 347), epididymal (group 2, n = 22) or testicular (group 3, n = 18) spermat...
متن کاملFertilization of in vitro matured human oocytes by intracytoplasmic sperm injection (ICSI) using ejaculated and testicular spermatozoa.
AIM To evaluate the fertilization competence of spermatozoa from ejaculates and testicle when the oocytes were matured in vitro following intracytoplasmic sperm injection (ICSI). METHODS Fifty-six completed cycles in 46 women with polycystic ovarian syndrome were grouped according to the semen parameters of their male partners. Group 1 was 47 cycles that presented motile and normal morphology...
متن کاملTesticular versus epididymal spermatozoa in intracytoplasmic sperm injection treatment cycles.
BACKGROUND Normal fertilization and ongoing pregnancy can be achieved using intracytoplasmic sperm injection (ICSI), even with severely immature spermatozoa. However, the published literature documents conflicting results as to the outcome of ICSI. METHODS Surgical extraction of spermatozoa in 111 ICSI treatment cycles performed over five years at the Assisted Conception Unit (ACU), Universit...
