RESUMO
OBJECTIVES: The objective of this paper was to assess whether the beneficial effects of a varicocelectomy on fertility are transitory or definitive after a first fathering. MATERIALS AND METHODS: This was a retrospective study which involved seven andrological centers. The files of 2223 patients who underwent subinguinal ligation of a high grade left varicocele for (oligo)±(astheno)±(terato)-spermia and infertility between January 1(st), 2002 and January 1(st) 2013 were reviewed. Inclusion criteria for the patients were the following: Sperm count improvement and fathering a child after an uneventful left varicocelectomy; 745 patients were considered. Patients who had undergone three assessments for (in-) fertility: Before surgery, before the first fathering and after the first fathering were included in the study. Each assessment included: Clinical history, physical examination, two sperm analyses, bilateral scrotal Duplex scans, blood hormonal levels [follicle stimulating hormone (FSH), luteinising hormone (LH), testosterone (T) and prolactin (PRL)]. RESULTS: Forty patients were finally studied; they all had an improved sperm count and had fathered once after surgery. Fifteen had fathered twice and still had their sperm count increased after the second fathering. Twenty-five patients could not father twice; 13 patients had their sperm count decreased after the first fathering and 12 did not. A decrease in testicular volume and an increase in FSH paralleled the worsening of sperm concentration, motility and morphology after fathering. No other differences could be observed between the groups. CONCLUSIONS: Our data indicated that the beneficial effects of a varicocelectomy might be transitory in some cases.
