Results of 550 transfers of cryopres jserved and thawed embryos were analyzed. A total number of 47 pregnancies was achieved (8.5 % per embryo transfer). Significantly better results were obtained when no selection of embryos before cryopreservation was made (i.e. pronucleate stage embryos and patients with all embryos frozen) compared to the „spare embryos'' group-14 pregnancies per 99 transfers (14 %) vs. 33 pregnancies per 451 transfers (7 %) respectively. Cultivation of thawed embryos before embryo transfer has a beneficial effect on implantation-19 pregnancies per 121 transfers (16 %) in the group of cultured embryos vs. 28 pregnancies per 429 transfers (7 %) in the group without cultivation. Cryopreservation significantly contributes to the effectivity of WF and provides further possibilities for conception in addition to those achieved from the fresh cycle.
Intracytoplasmic sperm infection (ICSI) is a very valuable method which implies a qualitative contribution to assisted reproduction and andrologically conditioned sterility, in particular. However, as one of the methods of cellular surgery it has its defined indications which must be respected.

Intracytoplasmic sperm injection (ICSI) is a procedure which dramatically eliminates the necessity to use donor sperm in androgenically conditioned sterility and enables almost all affected couples to achieve pregnancy.. The results in this group, till recently untreatable, are at least comparable with results achieved in the standard IVF programme. The standard success of the transport IVF programme was confirmed also in the transport IVF-ICSI programme. The transport of gametes does not influence the achieved results. It seems that for the results of the transport programme the indication and possibly other (gynaecological) factors of sterility are decisive. Intracytoplasmic sperm injection has become due to its effectivity an integral part of our IVF programme.

Azoospermia is no longer a clear indication for using donor sperm. Aspiration of epididymal sperm or extraction of testicular sperm offers the same hope of pregnancy as ICSI using ejaculated sperm. Not even the high effectivenet8 of ICSI should be the reason for less intensive efforts to assess the exact cause of azoospermia, in particular with regard to genetic aspects. This work was supported by the Grant Agency of the Ministry of Health of the Czech Republic grant No. 3050-2.
