Abstract

Purpose

The results of subzonal insemination (SUZI) and in vitro fertilization with microdroplet insemination used in couples with male-factor infertility are presented.

Results

The total fertilization rate was 17.4% for SUZI (n=89) and 49.3% for microdroplet IVF (n=100). The fertilization rate for standard IVF (n=510), not including any male-factor infertility and performed during the same period, was 73.2%. The “take-home baby rate≓ per started cycle and per embryo transfer (ET), respectively, was 10 and 17.6% for SUZI and 20 and 24.7% for microdrop IVF. For standard IVF these figures were 27 and 31.7%.

Conclusion

It was concluded that microdroplet IVF can be used with good results in cases of moderate malefactor infertility. The normal (2PN) fertilization rate with the SUZI technique was only 15.1%. However, despite the low fertilization rate, SUZI should be considered when dealing with severe male-factor infertility.
