Male infertility caused by anejaculation is common after spinal cord injury (SCI) and following retroperitoneal lymph node dissection (RPLND) for testicular cancer. Other conditions sometimes associated with neurogenic ejaculation loss are diabetes mellitus, multiple sclerosis, extensive pelvic surgery and adult myelodysplasia. Primary absence of ejaculation also has been described. Few treatment options exist for these patients, if they wish to father a child. With electroejaculation (EEJ), or the low-current stimulation of the ejaculatory organs via a rectal probe, emission of semen can be initiated in these men. In non-SCI-patients EEJ requires general anaesthesia. The collected semen is washed and the motile sperm fraction isolated before artificial insemination (AI) of the partner. At the University of Michigan 198 men have been treated between 1986 and December 1991. An ejaculate could be obtained from nearly all patients. A major obstacle to success is the severe asthenozoospermia and the poor functional quality of the obtained sperm samples. This can be caused by the EEJ-technique itself, as well as by the long anejaculatory status. A semen sample with at least 10 million progressively motile sperm cells, useful for AI, was obtained in 75% of the SCI men and in 87% of the men following RPLND. In the couples wishing insemination, 49 pregnancies were induced, accounting for an overall pregnancy rate of 35% per couple. Thirty five healthy babies have been born. Only three complications were encountered. At Hannover Medical School only few patients have been stimulated to date. We could obtain an adequate sperm sample for AI from all of them. No complications were seen. As the first couple has just entered the phase of AI with husband sperm, an analysis of these results would be premature. Electroejaculation combined with artificial insemination is an efficient and safe treatment of male infertility due to neurogenic anejaculation.
脊髓损伤(SCI)后以及因睾丸癌进行腹膜后淋巴结清扫术(RPLND)后,无射精导致的男性不育较为常见。其他有时与神经源性射精丧失相关的疾病有糖尿病、多发性硬化症、广泛的盆腔手术和成人骨髓发育异常。也有原发性无射精的描述。对于这些希望生育孩子的患者,治疗选择很少。通过电射精(EEJ),即通过直肠探头对射精器官进行低电流刺激,可以使这些男性射出精液。在非SCI患者中,EEJ需要全身麻醉。收集到的精液经过洗涤,在对伴侣进行人工授精(AI)之前分离出有活力的精子部分。在密歇根大学,1986年至1991年12月期间对198名男性进行了治疗。几乎所有患者都能获得射精。成功的一个主要障碍是严重的弱精子症以及所获得精子样本的功能质量较差。这可能是由EEJ技术本身以及长期无射精状态导致的。75%的SCI男性和87%的RPLND术后男性获得了一份对AI有用的、至少含有1000万个进行性运动精子细胞的精液样本。在希望进行授精的夫妇中,诱导了49次妊娠,每对夫妇的总体妊娠率为35%。已出生35名健康婴儿。仅出现了3例并发症。在汉诺威医学院,迄今为止仅对少数患者进行了刺激。我们从所有这些患者中都获得了用于AI的足够精子样本。未观察到并发症。由于第一对夫妇刚刚进入使用丈夫精子进行AI的阶段,对这些结果进行分析还为时过早。电射精结合人工授精是治疗神经源性无射精导致的男性不育的一种有效且安全的方法。
