H. Fuse et al., EFFECT OF VARICOCELE ON FERTILITY POTENTIAL - COMPARISON BETWEEN IMPREGNATING AND NONIMPREGNATING GROUPS, Archives of andrology, 35(2), 1995, pp. 143-148
Sixty patients with varicocele, complaining of infertility, underwent
a corrective operation. Eighteen (30%) of the 60 patients impregnated
their mates (impregnating group). Sperm concentration significantly in
creased after the operation in the impregnating group (p < .05), but n
ot in the patients who failed to impregnate their mates (nonimpregnati
ng group). Sperm motility was not altered after the operation in these
two groups. Sperm velocity significantly increased postoperatively in
the impregnating group (p < .05), while linearity was not altered in
either group. Sperm swelling significantly increased postoperatively i
n the impregnating group (p < .05), but not in the nonimpregnating gro
up. Preoperative sperm parameters were not different between the two g
roups. Varicocele may disturb sperm function including sperm motion be
sides spermatogenesis and may impair the fertility potential. However,
a prospective large-scale controlled study is required to obtain a de
finitive conclusion.
