The outcome of intracytoplasmic sperm injection is unrelated to ‘strict criteria’ sperm morphology

Sperm morphology was assessed according to the ‘strict criteria* established for in-vitro fertilization treatment in the semen samples used for 354 consecutive treatment cycles for intracytoplasmic sperm injection (ICSI). The semen samples were classified according to the three predictive categories...

Description
Summary:Sperm morphology was assessed according to the ‘strict criteria* established for in-vitro fertilization treatment in the semen samples used for 354 consecutive treatment cycles for intracytoplasmic sperm injection (ICSI). The semen samples were classified according to the three predictive categories of the Tygerberg strict criteria: excellent prognosis (>14% morphologically normal spermatozoa), good prognosis (4–14%) and poor prognosis (
