Comparison between the first and the second electroejaculate qualities obtained from neurologically intact men suffering from anejaculation.

BACKGROUND: Electroejaculation is an artificial method used to procure semen from neurologically intact men suffering from anejaculation that have failed other treatments. In order to establish the consistency of semen parameters in repeated electroejaculations, we compared retrospectively the quality of the first and the second electroejaculates of anejaculatory men who were not suffering from any known neurological problems. METHODS: Between 1995 and 2004, 59 neurologically intact men suffering from anejaculation underwent multiple electroejaculations. Sperm quality of the first and the second ejaculates was compared. RESULTS: A significant difference of 0.33 +/- 0.16 ml in the volume of the antegrade portion was found (P = 0.023). The results showed no significant difference in the concentration, motility, count and total motile count of the antegrade ejaculates. In retrograde ejaculates there were no significant differences in the count, motility and total motile count. Neither was there any difference in the total count and the total motile count of both fractions. CONCLUSIONS: Electroejaculation is a reliable method for semen procurement in men suffering from anejaculation. Since semen parameters are consistent, repeated procedures are not justified for improving the sperm quality in anejaculatory, neurologically intact men.

Comparison of semen quality obtained by electroejaculation and spontaneous ejaculation in men suffering from ejaculation disorder.

BACKGROUND: Electroejaculation has become an accepted form of semen procurement in men suffering from anejaculation. However, sperm in these ejaculates often exhibit low motility. The aetiology of asthenozoospermia remains uncertain. It may be related to primary low-grade motility of sperm from anejaculatory men or to detrimental effects of the electroejaculation process itself. The aim of this study was to determine whether the procedure of electroejaculation alters the quality of the semen by comparing the characteristics of the electroejaculates with those of the normal ejaculates of the same patients. METHODS: Nine men suffering from ejaculation disorders underwent 14 procedures of electroejaculation. The sperm concentration and motility of the 14 samples from electroejaculation were compared with 20 collected at a later date after successful ejaculation by the same patients. RESULTS: The mean +/- SD concentration of the electroejaculates was (52.3 +/- 42.1)x10(6)/ml and of the natural samples (67.4 +/- 38.1)x10(6)/ml. No statistical difference was found between the two groups. The mean percentage of sperm showing progressive motility following electroejaculation was 23.1 +/- 18.8% and 36.3 +/- 16.7% after spontaneous ejaculation. No statistical difference was found between the groups (P = 0.082). Likewise, the quality of sperm motility was similar after both methods of procurement. CONCLUSIONS: In our small-sized study group (nine men with ejaculation disorders), the concentration and the motility of sperm obtained by electroejaculation were not significantly different from sperm obtained naturally.

Electroejaculation with a foley catheter in the bladder.

Electroejaculation has been successfully used for sperm procurement in anejaculatory men desiring fertility. The electroejaculation procedure begins with complete catheterization of the bladder and instillation of an insemination medium into the bladder as a buffer. This step can minimize possible detrimental effects of urine on any retrograde ejaculate. The catheter is then removed. After the collection of the antegrade ejaculate, the bladder is catheterized again. Our objective was to evaluate the possibility of performing electroejaculation while the Foley catheter is instilled in the bladder. Eleven men with anejaculation underwent 22 procedures of rectal probe electroejaculation. Each patient underwent electroejaculation twice, once without the catheter instilled in the bladder (standard method) and once with it. The 2 methods, with and without the catheter, showed no significant differences in volume, concentration, motility, count, and total motility of the antegrade ejaculate. In retrograde ejaculate, there were no significant differences in the count, motility, and total motility. In addition, there was no difference in the total count and the total motility of both fractions in the 2 methods. In this study, we show that ejaculation can be achieved while the Foley catheter is instilled in the urethra without any detrimental effect on the sperm. Therefore, we recommend not removing the Foley catheter while performing electroejaculation.
