title: Intracytoplasmic sperm injection allows normal pregnancy rates for males 40 with low hypoosmotic swelling test scores even when complicated by very low motility percentage.
abstract: OBJECTIVE
  To determine if the additional burden of low percentage motility reduces the chance that sperm with low hypoosmotic swelling (HOS) test scores will achieve a pregnancy following in vitro fertilization (IVF) with intracytoplasmic sperm injections (ICSI).
  
  
  METHODS
  Couples undergoing IVF-embryo transfer (ET) and ICSI for low HOS tests (< 50%) were retrospectively identified. The percentage motility was divided into deciles. Pregnancy rates were determined according to the deciles of motility.
  
  
  RESULTS
  No differences in clinical or live delivered pregnancy rates per transfer were found in even the very lowest percent motility category.
  
  
  CONCLUSIONS
  The added complicating factor of low percentage motility added to sperm with low HOS test scores does not reduce the effectiveness of IVF with ICSI.
