Restoration of antegrade ejaculation after transurethral bladder neck injection of Deflux for retrograde ejaculation: a case report of natural conception

Abstract

Retrograde ejaculation contributes to male infertility. Pharmacotherapy has a limited role in retrograde ejaculation. Deflux, a viscous substance, consists of two components: dextranomer microspheres and stabilized hyaluronic acid for the treatment of children with vesicoureteral reflux. According to the published articles, the authors described the first case achieved not only restoration of antegrade ejaculation but also followed conception of the spouse after transurethral bladder neck injection of Deflux. A 30-year-old male kept infertile after 3 years of marriage. The patient reported that he could not ejaculate in an antegrade direction after puberty when he reached sexual climax. There was no semen expulsed from the urethral meatus. Medicine prescribed by a local hospital didn’t restore normal ejaculation. Four embryos fertilized by intracytoplasmic sperm injection developed well until transplantation, but none survived. The local reproductive center confirmed that his spouse preserved full capacity of fertility. He was diagnosed as retrograde ejaculation by real-time monitoring of transrectal ultrasound. He received transurethral bladder neck injection of Deflux. One month later, the patient restored antegrade ejaculation and the spouse of the patient conceived. During 18 months of follow-up, no related complications of the surgery have been observed. Transurethral bladder neck injection of Deflux can be considered as an alternative treatment method for retrograde ejaculation, and natural conception is possible thereafter.
