“…This could be the result of a deleterious eect of the electric current. Indeed, Linsenmeyer et al 14 showed that the current had a negative eect upon the motility of spermatozoa. In vitro, after a 2 min application of a 100 mA current, the spermatozoa exposed to the current are less motile than those that are not exposed.…”

This is a retrospective study of 39 male spinal cord injured patients who, over the last 5 years, have consulted us for ejaculatory dysfunction or infertility. All of these patients underwent at least two distinct sessions during which attempts were made to induce an ejaculation by vibratory stimulation, electric stimulation, or by using subcutaneous physostigmine. A semen analysis was performed each time that an ejaculate was obtained. By one or more of these techniques, 75% of these subjects were able to ejaculate. The level of the neurological lesion had a signi®cant in¯uence on the success rate. Likewise, the mode employed to produce an ejaculation in¯uenced certain characteristics of the sperm collected (mean volume, percentage of motile forms), the best results being obtained by vibratory stimulation. Among the 10 couples who had consulted us for medically assisted reproduction, three pregnancies were obtained, two of which resulted in the birth of healthy children. Although the techniques of stimulation that we use allow ejaculation, the possibilities of reproduction remain limited in particular because of the diculty in obtaining semen of adequate quality. Nevertheless, recent methods of micromanipulation of gametes should considerably improve the prognosis of the seminal insuciencies in men with spinal cord injury.

“…33 Further studies to elucidate the cause The signi®cant dierence between the better semen parameters of the antegrade rather than retrograde ejaculate, might be explained by the fact that the former semen is not contaminated with urine and is`fresher'. 35 There was no signi®cant improvement concerning sperm quality parameters after repeated stimulations.…”

Treatment of male infertility due to spinal cord injury using rectal probe electroejaculation: the Israeli experience

et al. 2001

Study design: Male infertility caused by anejaculation is common among patients with spinal cord injury (SCIP). The fertility options for SCIP have improved impressively over the past 10 years. We present the Israeli experience in the treatment of infertility in a large series of SCIP. The issues which are addressed include the treatment of ejaculatory dysfunction, seminal quality and fertility management in SCIP. Setting: Sexual rehabilitation clinic, Neuro-Rehabilitation department, Sheba Medical Center, Israel. Methods: Between June 1992 and May 1998, a total of 84 consecutive SCIP were treated in our clinic with electro-ejaculation (EEJ), representing a sample of the SCIP population, composed mostly of young men traumatically injured. The patients have sustained dierent levels and completeness of spinal injury. Among the patients 33 were interested in achieving pregnancy (39.3%), while the rest were interested in determining fertility potential for family. With EEJ, a low-current stimulation of the ejaculatory organs via a rectal probe is done. The collected semen is used for fertility determination or for fertilization. Results: Eighty-four patients were treated by EEJ. Mean age was 31.3 and mean age at injury was 21.7. There were 29 cervical, 50 thoracic and ®ve lumbar lesions. Sixty-three had complete injury (ASIA A) and 21 incomplete (ASIA B -15, ASIC C -5, ASIA D -1). Fifty-nine had upper motor neuron lesions, and 25 had lower motor neuron. A total of 355 stimulations were performed. Ejaculate was obtained in all patients in 350 stimulations (98.6%), and sperm was present in 74 patients (88.1%) in 296 of the stimulations (83.4%). Fairly good numbers of spermatozoa were obtained, whereas sperm motility and morphology of spermatozoa were low in most cases. A signi®cant dierence in sperm count, motility and morphology was noted between antegrade and retrograde samples. No signi®cant improvement in sperm quality after four repeated consecutive stimulations was noted in 38 SCIP. Side eects were minor and encountered in 16 patients (19.1%). Out of 33 couples who wished to achieve pregnancy, 26 reached the stage of insemination. Four pregnancies were achieved after 33 cycles of InUterine-Insemination (pregnancy rate 28.6% per couple), and 15 after 68 cycles of In-VitroFertilization (micromanipulation) (pregnancy rate of 68.75% per couple). In all, of 101 conception attempts 23 were successful, resulting in pregnancies in 18 couples, and accounting for an overall pregnancy rate of 70% per couple. Conclusion: The high percentage of pregnancies imply that, despite the typically poor sperm motility noted in EEJ, rectal probe EEJ combined with assisted reproductive techniques, and performed by a team approach, is an ecient and safe technique for treating infertility among SCIP.

“…The catheter is inserted using normal saline as a lubricant to avoid possible problems associated with the use of lubricant gels. 24,27 Prior to the introduction of this technique a bu er solution (HEPES/HTF Bu er, North Shore ART, Sydney) was instilled into the emptied bladder to minimise the adverse e ects of urine on sperm motility 28 in any retrograde emission. The retrograde specimen was then obtained by catheterisation after the procedure was completed.…”

A comprehensive approach to the management of male infertility following spinal cord injury

Objectives: To review the outcomes of management of male infertility following spinal cord injury in a specialised fertility clinic. Study Design: Retrospective review of medical records. Setting: The Fertility Clinic of a 45-bed spinal cord injury service in New South Wales, Australia. Methods: The medical and fertility clinic records of 113 males who attended the clinic between 1987 and 1997 were reviewed. Results: The rates of semen retrieval using vibroejaculation and electroejaculation were 67% and 97% respectively. Thirty-one individuals (37%) and their partners sought assistance with the primary aim of achieving a pregnancy. Intravaginal insemination (IVI) undertaken at home following vibroejaculation resulted in a pregnancy rate per cycle of 22%. Electroejaculation and IVI proved less successful with a pregnancy rate per cycle of only 5%, although with intrauterine insemination (IUI) this rate improved to 30%. Micromanipulation in vitro fertilisation (IVF) procedures, primarily intracytoplasmic sperm injection, were used in 18 couples resulting in a pregnancy rate per cycle of 19%. In the 31 couples there have been a total of 17 pregnancies in 97 cycle attempts for an overall pregnancy rate per cycle of 18% and a cumulative pregnancy rate per couple of 55%. Twelve of the pregnancies have resulted in 14 live births (including two sets of twins), there were three pregnancies ongoing at the date of review and there have been two spontaneous abortions. Conclusion: The bene®ts of a specialised fertility clinic o ering a comprehensive, clientfocused approach with education, fertility assessment and a range of semen retrieval and assisted reproduction options, are highlighted.
