Effect of varicocoelectomy on seminal fluid parameters

Infertility can be a source of anxiety and marital disharmony to a couple. The male factor traditionally contributes 40%. Varicocoeles are a significant cause of male infertility. To assess the effect of varicocoelectomy on seminal fluid analysis parameters in sub-fertile males. This was a prospective study of fifty four patients who presented with infertility to the urology clinic of University of Port Harcourt Teaching Hospital, Port Harcourt, Nigeria between January 2015. and January 2016 . Those who had clinically palpable varicocoeles as the only suspected cause of their infertility were enrolled. The varicocoeles were classified into right, left or bilateral and graded into grades 1, 2 and 3 using Dubins criteria. Each patient had two semen analyses done two weeks apart and underwent a bilateral varicocoelectomy via the inguinal approach. Seminal fluid analyses were done post operatively at four and six months. Of the 54 patients that underwent varicocoelectomy, 11 (20.4%) had azoospermia, 28 (51.9%) had oligospermia and 15 (27.8%) had counts greater than 20 million but less than 40 million. Following varicocoelectomy there was a statistically significant increase in overall motility (p=0.000), morphology (p=0.000), density (p=0.000) and semen volume (p=0.004). Assessing only oligospermic patients there was no significant improvement in morphology (p=0.160). Azoospermic patients showed statistically significant improvement in all parameters though the values were well below those accepted for spontaneous conception. Varicocoelectomy improves semen parameters in patients with varicocoele induced semen anomalies; it may provide an option for retrieving viable semen for patients with varicocoele induced azoospermia.
