A pregnancy obtained in a patient with 46XY gonadal dysgenesis (Swyer's syndrome) after ovum donation and IVF/ET is described. The efficacy of this technique in overcoming particular cases of otherwise irreversible infertility is discussed.

Assisted reproductive technologies in severe male infertility.

The increasing incidence of male subfertility as an indication for ART is first discussed. The tendency to use assisted reproduction techniques in such cases is attributed to the disappointing results of classical treatments. The Authors deal with two problems: the choice of the best treatment methods of the sperm and the choice of the best technique of ART for treating male infertility. The analysis of 138 couples treated for male subfertility showed that the centrifugation on discontinuous Percoll gradients (CDPG) and especially on the mini-Percoll (mini CDPG) offers the best results if compared with pellet swim up and other techniques. With reference to the technique of choice, an accurate analysis of tubal (TET and ZIFT) and uterine (IVF/ET) transfers shows that no advantage seems to be obtained with the more sophisticated and exacting tubal transfer. This final conclusion is presently evaluated on the basis of a retrospective study.

The use of three different therapeutic protocols according to the immunologic pathology present in three women with recurrent spontaneous abortion and fetal death for immunologic reasons: flucortolone and salicylates; high-dose intravenous gammaglobulins; subcutaneous heparin.

The authors report three cases of immunologic spontaneous abortions and fetal death. In the first patient there was lupus-like anticoagulant activity with a diagnosis of sub-clinical autoimmune disease; the second showed inadequate blocking factor activity, while the third subject presented excessive lymphocytotoxicity. In these cases three different therapeutic protocols were successfully used: flucortolone and salicylates, high-dose intravenous gammaglobulins and subcutaneous heparin.

Ultrasonography and blood flow velocity waveform assessment in human fetuses.

The authors report their experience with the use of ultrasonography and fetal blood flow measurement in the evaluation of fetal conditions recording patients with previous repeated immunologic abortion (R.I.A.) and with pre-eclampsia. In both groups of patients, the two biophysical methods, proved to be extremely valuable indicators of the fetal conditions.

Uteroplacental blood flow in pregnant women with hypertension and recurrent spontaneous abortion.

Uterine velocimetry was performed in 13 pregnant women with pregnancy induced hypertension (PIH) and in 15 pregnant women with recurrent spontaneous abortion syndrome (RSA-S). Measurement were performed on both uterine arteries and averaged. 75% of PIH group had RI 95th percentile from the first measurement (20 weeks gestation). In the RSA-S group, RI was between 75th and 95th percentile, suggesting an almost pathological vascularization.
