Testicular 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...
متن کاملBirth after intracytoplasmic sperm injection of ejaculated spermatozoa from a man with mosaic Klinefelter's syndrome.
AIM To report a birth after intracytoplasmic sperm injection (ICSI) of ejaculated spermatozoa from a man with mosaic Klinefelter's syndrome detected by fluorescence in situ hybridization (FISH) analysis. METHODS A 35-year-old man with a normal appearance consulted our hospital because of sterility over a 5-year period. Chromosome analysis showed low-incidence mosaic Klinefelter's syndrome. Us...
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 کاملCorrelation between motility of testicular spermatozoa, testicular histology and the outcome of intracytoplasmic sperm injection.
The objective of the present study was to analyse the influence of motility on the results of intracytoplasmic sperm injection (ICSI) when testicular spermatozoa are used for microinjection and to correlate this with testicular histology. A total of 197 ICSI treatment cycles (167 couples) was analysed retrospectively in which testicular spermatozoa were used, because of complete azoospermia, fo...
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...
