[Triplet pregnancy after intracytoplasmic sperm injections].
Morphology of the spermatozoa is one of the major criteria in severe male subfertility. We report on a case of severe Oligoasthenoteratozoospermia in which a triplet pregnancy could be achieved after intracytoplasmic sperm injection (ICSI). After treatment with GnRH-analogues/HMG/HCG seven oocytes of metaphase II could be retrieved and injected. Three of them fertilised and were transferred as four-cell stage embryos after two days. Seven weeks later an intact triplet pregnancy could be detected by ultrasonography. The severe sperm defects in this case were evaluated with the technique of electron microscopy. Ultramorphology of spermatozoa appears to have an important predictive value for fertilisation and pregnancy in classical IVF. Its value for the assisted procreation techniques such as ICSI remains to be investigated.
