Varicocele represents the most common cause of male infertility, and most
reports indicate that varicocelectomy has a beneficial effect on male
fertility and pregnancy outcome. Assisted reproductive technologies (ARTs) are
an alternative to varicocelectomy for the management of couples with a
varicocele. The age of the female partner is important in the decision-making
process; however, the true influence of female age on pregnancy outcome
following varicocelectomy or ART in these couples is unknown. We evaluated the
outcomes of 2 cohorts of infertile men with a varicocele and a female partner
35 years of age or older; one group selected varicocelectomy and the other a
nonsurgical approach. We reviewed a group of consecutive infertile men who
underwent microsurgical varicocelectomy and whose partners are 35 years of age
or older (n = 110). We also reviewed a consecutive group of men with
varicoceles who elected not to have surgery and whose partners are 35 years of
age or older (n = 94). The outcome measures included changes in semen
parameters, pregnancy rates (assisted and unassisted), and use of ART. The
surgical and nonsurgical groups had comparable semen parameters and female
ages. Mean sperm concentration and motility increased significantly after
varicocelectomy (P < .05). At a mean of 30 months follow-up, 35% of couples
in the surgical group achieved a spontaneous pregnancy and an additional 6%
achieved a pregnancy via ART (20% of this group attempted ART). In the
nonsurgical group, 25% achieved a spontaneous pregnancy and an additional 16%
achieved a pregnancy with ART (40% of this group attempted ART). This study on
the natural history of infertile men with varicocele and advanced female age
suggests that the surgical and nonsurgical approaches offer comparable
pregnancy outcome (combined assisted and unassisted pregnancy rates are about
40%). Overall, these data suggest that varicocelectomy is an acceptable option
for couples with advanced female age, but other female factors must be
considered in the decision-making process.
