“…Men with partly preserved sensation may experience significant discomfort and thus require either spinal or general anaesthesia before application of electroejaculation (Ohl et al, 1997;Sonksen & Ohl, 2002). Electroejaculation is successful in producing an antegrade specimen in 63% of men with lower motor neuron lesions (below T10) and in 93% of men with upper motor neuron lesions (above T10) (Momose et al, 1995). Other investigators have reported an overall ejaculatory success rate ranging between 80% and 100% (Warner et al, 1986;Ohl et al, 1989;Nehra et al, 1996;Sonksen & Ohl, 2002).…”

Erectile function and male reproduction in men with spinal cord injury: a review

Spinal cord injury (SCI) in men results in defects in erectile function, ejaculatory process and male reproductive potential. There are alterations in the capacity of men with SCI to achieve reflexogenic, psychogenic and nocturnal erections. The sexual function in different stages after SCI and the types of erections depend mainly on the completeness of the injury and the level of neurological damage. Furthermore, most of the SCI men demonstrate defects concerning the entrance of semen into the posterior urethra and the expulsion of the semen through the penile urethra and the urethral orifice. In addition, SCI men develop defects in the secretory function of the Leydig cells, Sertoli cells and the male accessory genital glands. The overall result is a decreased quality of the semen is recovered either with penile vibratory stimulation (PVS) or with electroejaculation. Nowadays the therapeutic andrological approach of SCI men focuses on achievement of erectile function, recovery of spermatozoa and assisted reproductive technology. The first line of therapy recommended for infertility in SCI men is collection of semen via PVS with concomitant evaluation of total motile sperm yields for assisted conception which may include intravaginal insemination, intrauterine insemination, or in vitro fertilisation/intracytoplasmic sperm injection. Patients failing PVS may be referred for electroejaculation or surgical sperm retrieval.

“…It has been consistently recognized that semen obtained from spinal cord injury men by the present technique show poor sperm motility. 1,8 Pregnancy rates are thus low despite high induction rates of ejaculation by electroejaculation. The ®rst healthy live birth after electroejaculation was reported by Francois and associates in 1978.…”

“…9 The authors have attempted AIH on 54 occasions for 11 couples and reported the ®rst two cases of spinal cord injury men fathered children by electroejaculation in Japan. 1 Pregnancy can be e ectively achieved by advanced reproductive technology (ART) such as in vitro fertilization ± embryo transfer (IVF-ET), zygote intrafallopian transfer, gamete intrafallopian transfer, subzonal insemination and ICSI, even if few motile sperm are made available by electroejaculation. Since Ayers and associates 10 achieved the ®rst live birth by electroejaculation combined with IVF-ET in 1988, several pregnancies have resulted from a combination of electroejaculation and ART, resulting in healthy live births.…”

Fathering of a child with the assistance of electroejaculation in conjunction with intracytoplasmic sperm injection: case report

1997

View full text Add to dashboard Cite

Ejaculatory failure and poor fertility are major problems for patients with spinal cord injury, who wish to father children. Arti®cial ejaculation in conjunction with assisted reproductive techniques has been proposed as a possible solution to this situation. In this paper, we presented the case of a tetraplegic man who fathered a child with the aid of electroejaculation with intracytoplasmic sperm injection (ICSI).

“…16 The couple performed eight cycles of vaginal self-insemination and six cycles of IUI, none of which resulted in pregnancy. In principle, we consider the sperm motility rate of a good candidate for arti®cial insemination to be higher than 50%.…”
