What is the effect of laser anatomical endoscopic enucleation of the prostate on the ejaculatory functions? A systematic review

Introduction Laser anatomical endoscopic enucleation of the prostate (LAEEP) has emerged as a promising new approach in endoscopic surgery for BPH. LAEEP could still result in ejaculatory dysfunction. Aim This systematic review aimed to examine the impact of LAEEP on male ejaculatory functions. Methods The review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, and 15 records were included. Outcomes of interest included ejaculatory dysfunction (retrograde ejaculation, painful ejaculation, etc.) and validated questionnaire scores. The quality of studies included in the systematic review was determined using QUADAS scoring. Results We retrieved data for 1877 men in 15 clinical studies investigating LAEEP surgery and reporting EjD rates. While only three of the obtained studies were on thulium fiber (ThuLEP), the rest were on holmium (HoLEP). The definition of "Ejaculatory Dysfunction" was not standardized, but in most works, it is referred to as retrograde ejaculation (RE). There were no data on the relationship between other LAEEP techniques and ejaculation functions. The authors compared the outcomes of used standard laser enucleation techniques with the modified techniques. The RE rate in LAEEP was 62.1 ± 25.1%, 71.3 ± 16.1% in standard techniques, and 27.2 ± 18.1% in ejaculation-preserving modified techniques ( p
