[Indications for intracytoplasmic sperm injection: possible influence of oocyte quality on the results]

Intracytoplasmic sperm injection is theoretically the first line treatment of many forms of severe male infertility, but the prognostic factors are to be determined according to the indications. Thus the results of two clinical teams working with the same biological Unit show statistically different pregnancy rates per oocyte pick-up (15.9% versus 35.7% - p < 0.02) and per transfer (16.9% versus 34.9% - p < 0.03). They could by explained by female factors such as age and ovarian response to stimulation, which probably have influence on embryonic quality.
