title: [In vitro fertilization in male subfertility--micromanipulation and special techniques for semen preparation].
abstract: Poor semen quality is increasingly the reason for human infertility. For couples who cannot be helped by conventional in vitro fertilization (IVF) treatment, micromanipulation methods and special sperm preparation techniques in in vitro fertilization hold considerable promise to enhance fertilization of the egg. "Partial zona dissection" (PZD n = 59) or "subzonal insemination" (SUZI n = 36) were performed in 88 IVF cycles obtaining a fertilization rate between 12.2% and 34.8% depending on the micromanipulation technique applied and a pregnancy rate of 19.2% per embryo transfer. So far ten ongoing pregnancies have occurred and five healthy children have been born. In certain cases of male factor infertility micromanipulation and special sperm preparation techniques therefore represent the only possibility of conceiving.
