[Spontaneous pregnancy in "sterile couples"]. / Le gravidanze spontanee nelle "coppie sterili".

The aim of the study is to evaluate the results of tests performed in "infertile" couples that have obtained spontaneous pregnancy. 953 couples were studied from 1986 to 1991; 108 spontaneous pregnancies occurred (11.1%). All patients were evaluated according to standard procedures recommended by literature. "Female factor" as cause of infertility was present in 41.5%; "cervical factor" was present in 19.4%; "male factor" was present in 48.1% while in 14.8% of the couples evaluated no pathology was showed. In this series, spontaneous pregnancy occurred within 4 year of infertility in more than 90%; no significant difference was present between primary and secondary infertility. A considerable incidence of pathologies was observed in couples that obtained spontaneous pregnancy. Our data suggest that common investigation for infertility may have not a real prognostic value.

[Induction of puberty and maintenance of secondary sexual characteristics in males with thalassemia major]. / Induzione della pubertà e mantenimento delle caratteristiche sessuali secondarie in maschi portatori di talassemia major.

18 males with beta-thalassaemia major were studied; mean age was 17.6 flAF 4.3, 8 of 18 males evaluated were prepubertal (Tanner 1), 5 were early and mid pubertal (Tanner 2-3) and 5 were full pubertal (Tanner 5). All patients (pts) underwent GnRH test and 61% showed positive response. 8 pts. were treated with hCG; 2 were azoospermic, 6 were aspermic. The starting dose was 1000 IU twice weekly; dose adjustments were made basing on testosterone levels and clinical features. Clinical examination, testosterone assays, semen analysis were performed every 3 months during the treatment period. Therapy was started 18-48 months ago and it is still in progress. Within 12 months of treatment 4 pts progressed to Tanner stage 4, 3 pts to Tanner stage 5, 1 showed no response. Semen analysis showed an improvement in 6 pts: after 12 months of therapy 1 pts was aspermic, 5 were azoospermic, 1 was oligozoospermic. Our data showed that hCG administration is effective in inducing and maintaining secondary sexual character.
