MICROINSEMINATION - A NEW METHOD OF TREAT ING STERILITY IN SEVERE MALE SUBFERTILITY

Microinsemination is a new method of treating sterility. It improves t he chance of fertilization in cases of severe male subfertility and of unexplained infertility. Fertilization is assisted by opening the zon a pellucida with a microneedle (PZD), by introducing a small number of sperms with a micropipette into the perivitelline space (SUZI) or by direct insertion of a spermatozoon into the ooplasm (ICSI). We report on the first delivery achieved by microinsemination (SUZI) at the Univ ersity Hospital Zurich and, as far as we know, in Switzerland.
