Abstract
The aim of this study was to evaluate the influence of sperm morphology, swim-up concentration, and insemination volume on pregnancy outcome in patients undergoing gamete intrafallopian transfer (GIFT) treatment in whom the male partner had a morphology of less than 14%. Only patients who received four oocytes were entered into this study (n=103). In all cases the swim-up procedure time was standardized to 1 h and the insemination concentration was standardized to 500,000 per oviduct. There was no significant difference in pregnancy rate when normal morphology, swim-up concentration, or insemination volume were used as predictors. In the P pattern group (<4% normal forms) only four of the 28 (14%) patients had ongoing pregnancies, whereas in the G pattern group (5% to 14% normal forms) 16 out of 75 (21%) had ongoing pregnancies (P vs G, p > 0.05; not significant). The fertilization rate among excess oocytes in the p pattern group was 18% but was 39% (p < .0001) in the G pattern group. When an attempt was made to compensate for low morphology by increasing insemination concentration no significant difference in the pregnancy rate between the P and G pattern groups in the GIFT program was recorded. This was not the case when the in vitro fertilization rate was used as an endpoint. Insemination volume and swim-up concentration played no role in pregnancy rate.
