[Analysis of decline in seminal fluid in the Italian population during the past 15 years].

Background And Aims: The authors wished to study whether there has been a real decline in the quality of semen over the past years, as reported in the literature by a number of studies. This paper analyses the basic parameters of semen from 1068 males who have acted as donors during the past 15 years (1981-1995) for our semen bank.

Methods: Tables have been drawn up showing the number of cases examined every year, the mean concentration of spermatozoa, the mean percentage of mobile sperm and the mean percentage of non-conforming elements.

Failure in intrauterine contraception. Analysis of 137 cases of unfavourable outcome.

137 cases of unfavourable outcome in IUD insertion (i.e. early removal or expulsion because of complications) were investigated as regards age, parity, previous intrauterine contraception, previous induced abortion, type of device inserted, and type of complications observed.

The efficacy of clarythromycin (A-56268, TE-031) in the treatment of genital chlamydial infection.

The authors report the preliminary results of an experience of treatment with clarythromycin in Chlamydia trachomatis endocervicitis/endourethritis; 100% of 51 outpatients treated had negative ELISA results 7-10 days after the end of treatment with clarythromycin 500 mg. b.i.

[Comparison of cytology and ELISA in the research on cervical Chlamydia infection].

Papanicolaou smears from 100 woman with ELISA Chlamydia-positive (42) and negative (58) endocervical smears were examined. Chlamydial endocellular inclusions were found in 3 ELISA positive and 2 negative smears, with an evident low sensitivity (7%) of cytology in the diagnosis of the endocervical infection. Furthermore, by statistical analysis it is clear that a negative test doesn't add anything to the pre-test probability (prevalence) of the infection.
