Predicting the adult daily sperm output after the first ejaculates in cockerels raised under different photoschedules.

In M33 cockerels, the rapid phase of testicular growth and the onset of sperm production were advanced either by increasing daylengths or an interrupted-night photoschedule; they were delayed by constant short days (8L). The results observed under constant long days (16L) were intermediate. In this strain, the cockerels maintained their mean testicular weight during the adult period while their daily sperm output (DSO) gradually declined. Individual variations in the DSO results were greater than individual variations in testicular weight. These variations did not appear to be influenced by the photoschedules. The differences in DSO observed between the best and the worst semen donors at the end of testicular development or thereafter remained relatively stable in ageing cockerels, except in birds submitted to increased photoperiods. This is the basis of the method described here for reliably choosing the best semen donors just before they are used as breeders.

[Successful andrologic-gynecological treatment of sterility caused by an ejaculation disorder after retroperitoneal lymphadenectomy].

A disturbance of emission is a frequent cause of sterility after retroperitoneal lymphadenectomy performed in the treatment of a non-seminomatous carcinoma of the testes. This is the first report in literature on the successful treatment of disturbed emission with subsequent pregnancy. The treatment consisted of a bolus injection of 15 mg midodrin hydrochloride i.v., rinsing of the bladder with tyrode solution, accurate timing of ovulation via sonography, and homologous insemination.

The only presence of sperm in urine does not imply retrograde ejaculation.

This is a retrospective study of clinical experience collected at the University Clinical Hospital over a 19-year period. Semen samples were analyzed according to WHO criteria. In the postmasturbatory urine, sperm count was performed. Data were expressed as total sperm number in urine (TSNU) and using a retroejaculation index. Patients were categorized into four groups according to the presence of sperm in the studied samples: a) in semen and urine; b) only in urine; c) only in semen; d) neither in semen nor in urine. A control group included nonretroejaculator patients. Retroejaculator patients are those whose TSNU is superior to 3.8 x 10(6) and the RI superior to 2.16%. While diagnosing retroejaculation, the only presence of sperm in the postmasturbatory urine is not adequate. The proposed index added to total sperm number in urine and semen volume may identify true retroejaculator patients.
