Semen cryopreservation from oncological patients: the Italian experience.

The aim of the study is to summarize official data on semen cryopreservation for oncological patients in Italy. The first private semen bank for oncological patients in Italy was founded by Colpi in 1983 in Milan. In 1987, the first public semen bank was established in "Macedonio Melloni" Hospital (Milan) by Ragni. Normal semen samples are usually present in only 40% of oncological patients. The rate of semen sample use for assisted reproduction techniques is similar to international data (5%). At present, semen cryopreservation is possible only in about 20 Italian centers.

[Male contraception].

The only safe method of male contraception is vasectomy, with high reversibility secured by microsurgery. Italy, however, suffers from a lack of regulations on this subject. Hormonal treatment (testosterone plus progestational hormones) is far from providing reliability and safety, while some perspectives, theoretical only for the time being, are offered by studies on functional infertility induced by either speeding up (ganglioplegic, sympathomimetic, parasympatholytic, oxytocin, endothelin, angiotensin) or inhibiting (sympatholytic) the sperm transport through the epididymis, or altering the epididymal environment (alpha-chloridin, chlorodeoxyglucose).

[Management of infertility following treatment of testicular tumors].

Testis cancer mainly affects patients in a reproductive age. Since at the present time recovery can be achieved in 84% of cases within ten years, there has been an increasing demand for paternity by these patients. In most cases, the preventive cryopreservation of spermatozoa and their subsequent use for assisted reproductive techniques can solve the problems connected with secretory infertility (no always reversible) caused by chemotherapy or radiotherapeutic treatment. Cryopreservation also allows to avoid the surgical taking of germinal cells either from testes or from seminal ducts in cases of anajeculation due to retroperineal lymphoadenectomy (present in 23.5-80% of cases). Failing the preventive cryopreservation, the surgical or microsurgical extraction of testis spermatozoa can be performed with success rates equal to 50%. Their use for intracytoplasmic sperm injection (ICSI) procedures presently seems to provide some encouraging results both for fertilization and pregnancy rates.

Effectiveness mechanism of chlomipramine by neurophysiological tests in subjects with true premature ejaculation.

The effectiveness mechanism of the chlomipramine treatment was evaluated by sacral evoked response (SER) and dorsal nerve somatosensory cortical evoked potential (DN-SEP) testings in 15 patients with true premature ejaculation (TPE). We couldn't demonstrate any significant difference between the values of either latency times or amplitudes of the evoked responses determined just before and at the end of the treatment with chlomipramine in these patients. However, the sensory thresholds were 24.4 +/- 4.3 V in the pretreatment term and 30.2 +/- 7.3 V at the end of the treatment. This difference is statistically significant (P = 0.0031). Our results suggest that chlomipramine increases the sensory threshold for the stimuli in the genital area.

Seminal tract washout: a new diagnostic tool in complicated cases of male infertility.

The diagnosis of azoospermia or severe oligospermia that is made using conventional techniques (testicular biopsy, epididymal exploration, and vasovesiculography) may in some cases remain a dilemma. In such circumstances, post-testicular causes of obstruction must be evaluated. Following the clinical experience acquired in a selected population of 150 severely infertile subjects, the total sperm count in the fluid obtained from the bladder after a seminal tract washout during vasovesiculography has proved to be a valid tool to diagnose the location of the (sub-)obstruction in the seminal tract in complicated cases. Some representative cases are presented. In particular, seminal tract washout (STW) helps to identify functional distal seminal tract emptying disturbances and epididymal incomplete obstruction.
